PVC Duplex Strainers
1) Select strainer size.
2) Input the design flow rate in GPM.
3) Input the Specific Gravity of the fluid if other than water.
4) Select the Viscosity if other than water.
The corresponding clean differential pressure chart will update automatically to reflect the data input.
NOTE: The inlet velocity should be ≤ 5 FPS and the maximum clean differential pressure should be ≤ 2 PSI.

The basket chamber covers for our PVC duplex strainers have been ergonomically designed with large handles for easy removal without tools. The inlet and outlet can be oriented on the same side as shown above or can be facing opposite directions (in-line flow configuration). The strainer bottom is flat and has molded mounting slots.
You can install plastic strainers into alloy pipelines, however it is suggested that you also include plastic pipe at least 10 pipe diameters long on both the inlet and outlet sides of the strainer to account for the different thermal expansion rates of alloy and plastics, pipe vibration and loading forces.
PVC duplex strainers usually ship within 7-10 days after receipt of an order. If lead time is critical please contact us and we'll confirm the lead time required.
The differential pressure calculator can be used to estimate the clean differential pressure for your specific application. The recommended fluid velocity minimizes the effects of valve closure and pump start-up or shut-down.
Likewise, the reason for the clean differential pressure limitation is to maximize the time between basket cleaning. Once the differential pressure is ≥ 5 PSI the basket should be cleaned.
