IMI-Series Hydraulic Suction Scanning Screen Filter

The High Performance Standard in Scanning Filtration

Rain Bird’s IMI-Series Hydraulic Suction Scanning Screen Filter provides worry free high-flow rate filtered water quality. Powered by source line water pressure, the filter’s backwashing system produces a concentrated high velocity reverse water flow to systematically clean the mesh screen of any entrapped contaminants. Models are available as a filter unit only, or as a filter assembly including bypass plumbing and valves for fast and easy installation on site.

Operation (see illustration to the right)

The unit consists of two stages of filtration, a coarse screen pre-filter and a stainless steel fine screen. Suspended solids accumulate on the inner surface of the fine screen, building up a filter layer which eventually restricts the filter and creates a pressure differential. Once the pressure differential reaches a preset level a rinse cycle is initiated by the Rain Bird supplied controller. The solids are removed from the fine screen using a concentrated backwashing method which aggressively sucks the accumulated dirt off the screen where it is carried to drain via the rinse valve. The dirt collector rotates while it moves linearly, ensuring the entire screen is cleaned each cycle. The process takes a matter of seconds, without interruption of system flow.

Monitoring and Controls

The standard Rain Bird automatic control system consists of a microprocessor based controller, a differential pressure switch and a solenoid actuated flush valve. The differential pressure switch monitors inlet and outlet pressures and comes factory preset to 7 psi. The flush valve is activated by the controller when the differential pressure exceeds 7 psi. The filtration system is automatically monitored and controlled on elapsed time since the last cleaning cycle or pressure differential (user definable). If timed cleaning cycles are utilized, the system will automatically default to a backwash based on differential pressure if a 7 psi differential pressure is reached before the next timed cleaning cycle. Standard Rain Bird automatic controls are available for 115 VAC and 230 VAC, 50 / 60 Hz (user-configurable) single phase power. Omni 2000 Controllers are used for single and dual filter applications. An Omni 150-I battery operated controller with DC Latching solenoid and optional Solar package is also available for single filters.

Construction

Rain Bird IMI-Series filters are built for years of durable, trouble-free service. The housing and covers of standard filters are made from thick wall high-grade, low-carbon steel. All exposed surfaces, both inside and out, polyester powder coated over a zinc phosphate primer coat. All wetted components are constructed of either engineered plastics or non-corrosive metals. Standard micron wire mesh screens are PVC-supported which virtually eliminates the possibility of screen collapse. Easy maintenance access to the internal components of the filter is via a removable front cover with handles that are secured to the front end of the filter housing. All wetted components are constructed of either engineered plastics or non-corrosive metals. Larger screens are manufactured in a modular form which allows replacement of sections of the wire mesh, rather that the entire wire mesh element. All Rain Bird IMI-Seriesfilters are also available in Stainless Steel construction, for the most demanding water quality applications.

IMG-Series Hydraulic Suction Scanning Screen Filter

Economy and Value with Lower Backwash Volumes

Rain Bird’s IMG-Series Hydraulic Suction Scanning Screen Filter provides worry free mediumflow rate filtered water quality. Powered by source line water pressure, the filter’s backwashing system produces a concentrated high velocity and low volume reverse water flow to systematically clean the screen of any entrapped contaminants. Models are available as a filter unit only, or as a filter assembly including bypass plumbing and valves for fast and easy installation on site.

Operation (see illustration below)

Dirty water enters the inlet (1), where it enters the fine screen (2). The water passes through the screen from the inside to the out (3). The solids accumulate on the inner surface of the screen creating a pressure differential across the screen. Once the pressure differential reaches a preset value, a rinse cycle is activated and the Rain Bird supplied control system opens the rinse valve (4) to drain. As a result, the pressure drops in the hydraulic motor chamber (5) and dirt collector assembly (6). The pressure drop causes water to backflush through the screen in a small concentrated area at the nozzle openings. The high velocity backwash stream pulls the dirt off the screen. The backwash water is carried through the collector and ejected out of the holes in the hydraulic motor (7). The dirt collector rotates while it moves linearly (on models with a piston assembly), ensuring the entire screen is cleaned each cycle. The process takes a matter of seconds, without interruption of system flow.

Monitoring and Controls

The standard Rain Bird OMNI 2000 control system consists of a microprocessor based controller, a differential pressure switch and a solenoid actuated flush valve. The differential pressure switch monitors inlet and outlet pressures and comes factory preset to 7 psi. The flush valve is activated by the controller when the differential pressure exceeds 7 psi. The filtration system is automatically monitored and controlled on elapsed time since the last cleaning cycle or pressure differential (user definable). If timed cleaning cycles are utilized, the system will automatically default to a backwash based on differential pressure if a 7 psi differential pressure is reached before the next timed cleaning cycle. Standard Rain Bird automatic controls are available for 115 VAC and are user configurable to 230 VAC, 50 / 60 Hz power.

Construction

Rain Bird IMG-Series filters are built for years of durable, trouble-free service. The bodies of standard IMG-Series filters are made from highgrade, low-carbon steel. All exposed surfaces, both inside and out, are polyester powder coated over a zinc phosphate primer coat. All wetted components are constructed of either engineered plastics or non-corrosive metals. Standard wire mesh screens are PVC-supported which virtually eliminates the possibility of screen collapse. All Rain Bird IMG-Series filters are also available in Stainless Steel construction, for the most demanding water quality applications.

IME-Series Electric Suction Scanning Screen Filter

High Performance Precision Scanning

Rain Bird’s IME-Series Suction Scanning Screen Filter provides worry free high-flow rate filtered water quality. Powered by source line water pressure and an electrical drive motor, the filter’s backwash system produces a concentrated high velocity reverse water flow to precisely clean the screen of any entrapped contaminants. Unique to this design, Rain Bird has eliminated potentially troublesome limit switches (for reversing the drive mechanism) and implemented a reversing mechanism that is simple and higher in reliability than other units on the market today. Models are available as a filter unit only, or as a filter assembly including bypass plumbing and valves for fast and easy installation on site.

How It Works (see illustration below)

The unit consists of two stainless steel stages of filtration, a coarse pre-filter and a fine screen. The fine screen presents a positive barrier to all particles larger than the openings in the screen. The unwanted solids accumulate on the inner surface of the fine screen, building up a filter cake which filters out even finer particles, creating a pressure differential. Once this pressure differential reaches a preset level, a rinse cycle is activated by the factory supplied control system. The rinse valve is opened to atmosphere dropping the pressure in the backwash chamber and dirt collector assembly. The pressure drop creates a backflush stream at each nozzle that aggressively sucks the dirt off the screen, similar to a vacuum cleaner. The backwash water and debris is carried through the collector and ejected out the rinse valve to a drain. At the same time the drive assembly rotates the dirt collector at a constant low speed and moves it linearly at a fixed rate, ensuring that the nozzles sweep the entire screen surface for 100% cleaning. The process takes a matter of seconds without interrupting system flow.

Monitoring and Controls

The standard Rain Bird control system consists of a programmable logic controller, a differential pressure switch, electric drive motor, and a solenoid actuated flush valve. The differential pressure switch monitors inlet and outlet pressures and comes factory preset to 7 psi. The housing mounted solenoid actuated flush valve and electric drive motor are activated by the controller when the differential pressure exceeds 7 psi. The filtration system is automatically monitored and controlled either on elapsed time since the last cleaning cycle or pressure differential (user definable). If timed cleaning cycles are utilized, the system will automatically default to a backwash based on differential pressure if a 7 psi differential pressure is reached before the next timed cleaning cycle. Standard Rain Bird automatic controls are available for 115 VAC and 230 VAC, 50 / 60 Hz (user-configurable) single phase power.

IMV-Series Automatic Self Cleaning Water Filters

Water Saving Filter Slashes Backwash Water By 90%

The IMV-Series units from Rain Bird provide efficient and reliable filtration, while conserving the amount of backwash water required. Due to its efficient rinse system, the IMV filter uses only 1 to 2 gallons per rinse cycle. This low flush volume makes it the ideal unit for a wide variety of applications. Designed for low flow applications, the unit is available with 3/4″ and 1″ inlet and outlet, to handle flow rates up to 27 gpm. The stainless steel fine screen is available in a variety of sizes to suit any application.

How It Works

Dirty water enters the inlet (1) into the center of the fine screen (2). The water then passes through the fine screen from the inside out and exits to the outlet (3).

The unwanted solids accumulate on the inner surface of the fine screen, building up a filter cake which filters out even finer particles, creating a pressure differential. Once the pressure drop reaches a preset level, a rinse cycle is activated by the control system, opening the rinse valve (4) to an atmospheric drain and closing the optional controlled outlet valve (C.O.V.) (5).

As a result, pressure drops in the hydraulic motor chamber (6) and the dirt collector assembly (7). The pressure drop creates a backflush stream, which sucks the dirt off the screen, similar to a vacuum cleaner. The backwash water is carried through the nozzles (8) and the direct collector tube before being ejected out of the holes in the hydraulic motor (9).

The water being ejected out of the hydraulic motor causes the direct collector to rotate, similar to a sprinkler. In addition, the pressure drop in the hydraulic motor chamber forces the dirt collector assembly to move axially, controlled by hydraulic piston (10). This combination of movements ensures that the entire screen area is cleaned each cycle.

IMC-Series Automatic Coarse Screen Filters

The Rain Bird IMC-Series coarse screen filters span the 10-3,000 micron filtration spectrum. The IMC filter is ideal for applications where fine filtration is unnecessary, or the high loading of large particles may require a separate filtration of coarse particles.

THE SOLUTION

As a solution, automatic coarse screen inline Rain Bird filters are available with a stainless steel perforated screen which is cleaned automatically. The housing is constructed of carbon steel, covered internally and externally by a baked-on polyester coating (other materials available upon request.) The filter’s internals are easily accessed by a removable bolted cover, allowing for ease of service and maintenance. All wetted parts are constructed of non-corrosive metals, allowing for extended service life.

CONTROLS

The state of the art PC-board-based, electrical and battery operated OMNI500 control system provides perfect rinse cycle activation using differential pressure, time cycle or volumetric flow.

OPERATION

During normal operation, the dirty water enters the inlet and travels to the concave surface of the perforated screen. The flow is longitudinal, trapping the large particles on the surface of the perforated screen. The water then exits the filter through the outlet. The screen rinse cycle initiation is accomplished by engaging a solenoid valve which controls the diaphragm valve located opposite of the filter cover. When the solenoid valve is triggered, the top portion of the diaphragm valve drains, causing the valve to open. When the valve opens, a portion of the water flows back through the screen, lifting the solids off. At the same time, a portion of the water flows from the inlet of the filter and out to be drained, carrying the accumulated solids with it.

IMM-Series Manual Filter

Protect Valuable Equipment With Cost Effective Filtration For Any System Rain Bird’s line of IMM-Series Manual Filters offer a solution for those systems with big operating problems but small operating budgets. Available in 1” to 8” line sizes, the filters are capable of handling flows up to 1320 gpm. Constructed of carbon steel and coated with extra durable polyester, electrostatically applied (and oven cured) on a zinc phosphate layer, the filters are designed with durability in mind. The screen is available in sizes down to 72 micron/200 mesh, allowing the unit to be used in a variety of applications.

Benefits

• Low Cost
• No Moving Parts
• Screens Down to 72 Micron

How It Works

Dirty water enters the inlet (1) and passes through the screen (2) to the outlet (3). Unwanted particles accumulate on the outside surface of the screen. A manual backwash cycle is activated by opening the rinse valve (4) to drain. A portion of the water travels back through the screen, dislodging the particles. At the same time, a flow is induced across the surface of the screen, carrying the particles to drain. The screen can also be accessed for manual cleaning by removing the cover (5).

Installation Guidelines

• Filter must be installed horizontally with body pointing upwards and drain valve pointing down.
• Filter must be installed in the proper flow direction as indicated by the arrows on the housing.
• For ease of maintenance, install filter with inlet and outlet isolation valves.
• Be sure to leave sufficient space around the filter for screen removal and maintenance.
• For best results, operation with a clean screen pressure drop of 4 psi or less is recommended.
• Maximum Working Pressure: 125 psig; Maximum Fluid Temperature: 140°F.

Pumping water from wells or other sources with excessive amounts of sand, silt, or other abrasive grit particles can lead to the premature degradation of components. Rain Bird Centrifugal Sand Separators are designed to separate abrasive particles before they can enter a system, keeping equipment clean and clear of debris, which minimizes the amount of maintenance required and increases operational efficiency. These filters are designed and manufactured in the USA to exacting standards, providing many years of optimal performance.

Rain Bird centrifugal separators are designed for easy installation, minimal maintenance, and reliable operation. The separator removes sand and particles that are heavier than water (materials with a specific gravity of 2 or greater) before these particles can damage your system.

Liquids and solids enter the unit and begin traveling in a circular flow. This centrifugal action throws heavier particulates towards the filter walls and eventually downward in a spiral motion to the separation chamber. The particulates collect in the separation chamber and are purged manually from the system. The filtered water is then drawn to the separator’s vortex and through the outlet.

An optional automatic purge controller and valve can be used on all applications to automate the purge process, which eliminates the need for manual flushing. Small vertical design separators may be wall mounted or supported by the system piping.
