Frequently Asked Questions (FAQs)

1. What are the different types of suction strainer?

The different types of suction strainers include simplex strainers, y strainers, duplex strainers, and automatic strainers. Each type has its own advantages and is designed to remove large contaminants (40-microns or greater) from the material being processed.

2. Which type of strainer is used in pump suction?

A coarse mesh strainer is typically used in pump suction. It is installed at the suction inlet of the pump and helps collect large particles to prevent them from entering the pump. Inline filters, also known as return line filters or spin-on filters, are installed in the fluid return line.

3. What size is a suction strainer?

Suction strainers are available in sizes ranging from G 1/4 inch up to G 4 inch. They come with mesh sizes ranging from 1 up to 2 mm. These strainers are often combined with check valves and referred to as foot valves. They are typically mounted at the bottom of a suction line in a tank.

4. How does a suction strainer work?

A suction strainer is a valve that is installed at the inlet of the suction line. Its purpose is to prevent dirt from entering the system. Suction strainers with integrated foot valves also help prevent the suction line from running empty after the pumping operation is completed.

5. What is the difference between T type and Y type strainer?

T-type strainers have a higher flow capacity and can quickly drain dangerous fluids. They also have a larger filtration system, allowing them to retain more particles. Y-strainers, on the other hand, are better suited for non-dangerous fluids in industrial pipelines.

6. What are common suction line sizes?

Common suction line sizes vary depending on the system. For standard residential systems, the liquid line diameter is usually 3/8 inches, while the suction line diameter can be 3/4, 7/8, or 1 1/8 inches, depending on the size and efficiency of the air conditioner or heat pump.

7. What is the pressure drop across a suction strainer?

If you experience excessive or erratic pressure drop across your hydraulic strainer, it could be due to factors such as using the wrong strainer size or type, a damaged or dirty filter element, high fluid viscosity, low fluid level or air entrainment, or blocked or leaking pipes.

8. What is the difference between a suction diffuser and a strainer?

Strainers are designed to remove debris from the flow to protect equipment like pumps, chillers, and boilers. Suction diffusers, on the other hand, are a specialized type of strainer used for direct attachment to specific pumping equipment inlets. They provide compact and accessible pipeline straining.

9. What is the difference between suction guide and Y strainer?

A suction guide has four times more filtration area compared to Y strainers, resulting in lower pressure drop. Suction guides are available with equal size flanges or a reduced outlet flange, allowing them to replace reducing elbows.
