Products Description
Overview
The suction strainer is a filter or sieve attached to the inlet end of a suction hose (or suction line) to prevent debris, silt, or large particles from being sucked into a pump when drafting (drawing) water from an external source (pond, pool, tank, etc.). Useing a Storz-type fitting/coupling - ensuring quick, secure connection to hoses or pumps that are built for Storz coupling. The strainer body itself often is aluminum alloy; the strainer grid typically stainless steel.
FAQ
Q: What is a Storz Suction Strainer?
A Storz Suction Strainer is a water intake accessory installed at the end of a suction hose when drafting water from open sources (rivers, lakes, ponds). It prevents debris, leaves, stones, and foreign objects from entering the pump and protects the pump impeller.
Q: How does it work?
The strainer acts as a filter by allowing water to enter through its perforated body while blocking solid particles that could clog or damage the pump.
Some designs include a non-return valve to prevent backflow and maintain prime.
Q: What Storz sizes are available?
Common sizes include:
Storz 65 (A-type)
Storz 75
Storz 100 (B-type)
Storz 150 (C-type)
Larger diameters are used for high-flow fire pumps.
Q: What materials are used?
Typical materials:
Aluminum alloy (lightweight, corrosion-resistant)
Stainless steel mesh or perforated steel
Rubber or brass valve parts (for non-return valve models)
Q: What is the function of the non-return valve?
The non-return valve:
Prevents water from flowing back out when the pump stops
Helps maintain pump priming
Reduces time needed to restart operations
Improves safety during drafting
