Shurflo® Pump Strainer

Shurflo Wing-Nut Strainer with 1/2-Inch Hose Barb

The Shurflo 255-225 wing-nut strainer is designed to protect compatible Shurflo pumps by preventing dirt, resin and other debris from entering the pump head.

It connects directly to the inlet port of Shurflo pumps with compatible 1/2-inch male ports, including the Shurflo 8000-946-138 12V pump. The opposite end features a 1/2-inch hose barb for connecting standard 12mm garden hose.

The transparent filter bowl allows you to see when cleaning is required, while the removable 50-mesh stainless-steel screen can be rinsed and reused.

IMPORTANT: THIS LISTING IS FOR ONE STRAINER ONLY. THE PUMP, HOSE, HOSE CLIPS, CONTROLLER, FITTINGS AND ALL OTHER ACCESSORIES ARE NOT INCLUDED.

Protect Your Shurflo Pump

Small particles of dirt, water-softening resin and tank debris can enter a pump and prevent its internal valves from sealing correctly. This can cause reduced pressure, irregular water flow or complete pump failure.

Installing this strainer before the pump creates a protective barrier that helps keep contaminants away from the pump head.

Key Benefits

• Direct pump connection: Attaches to compatible Shurflo pumps with 1/2-inch male inlet ports.

• 50-mesh stainless-steel screen: Captures small particles before they enter the pump.

• Transparent filter bowl: Makes it easy to see when the strainer requires cleaning.

• Reusable filter: Can be dismantled, rinsed and reassembled.

• 12mm hose connection: Accepts standard 1/2-inch garden hose.

• Hand-tightened wing nut: Allows straightforward installation and removal without specialist tools.

• Helps protect your warranty: Reduces the risk of pump damage caused by resin, dirt and other contamination.

Technical Specifications

Installation Directions

1. Switch off the pump and isolate the water supply.

2. Identify the pump’s inlet port. The strainer must be installed on the inlet side, before water enters the pump.

3. Attach the female wing-nut connection directly to the compatible 1/2-inch male pump port.

4. Tighten the wing nut securely by hand. Do not overtighten it or use excessive force.

5. Push the 12mm water-supply hose fully over the barbed inlet.

6. Secure the hose using a correctly sized hose clip.

7. Restore the water supply, switch on the pump and inspect the connections for leaks.

Cleaning and Maintenance

1. Switch off the pump and close the water supply.

2. Release any remaining pressure from the system.

3. Carefully remove the transparent filter bowl.

4. Remove the stainless-steel screen and rinse it thoroughly with clean water.

5. Check the screen, bowl and sealing gasket for wear or damage.

6. Refit the screen and hand-tighten the bowl.

7. Restore the water supply and check for leaks.

Clean the strainer regularly. The required cleaning frequency will depend on the cleanliness of the tank, water supply and connecting hose.
