Usage Precautions & Installation Tips

To ensure optimal performance and prolong pump service life, follow these guidelines:

Filter Requirement: Install a 25μm or finer filter (400 mesh recommended) at the pump inlet. For closed-loop systems, the filter can be placed at the outlet. Ensure the filter’s rated flow matches the pump’s requirements to avoid pipeline resistance increase.

Pipeline Installation: Align pipelines with pump inlets/outlets during installation and use proper pipeline supports. Do not apply eccentric torque or weight to the pump body, which may cause damage and leakage.

Dry-Running Notice: Avoid prolonged dry running at speeds exceeding 1600 rpm. Ensure the pump chamber is filled with liquid or wetted before operation.
