Usage Precautions & Installation Tips

Filter Requirement: Install a 400-mesh (25μm) or finer filter at the pump inlet (or outlet for closed-loop systems). Ensure the filter's rated flow is at least 1.5 times the pump's rated flow to avoid pipeline resistance.

Dry Running Caution: Dry running is not recommended—prolonged dry operation at high speeds will cause permanent damage to PEEK gears and ceramic shafts. Always ensure the pump chamber is filled or wetted before use.

Pipeline Installation: Align pipelines with the pump's inlet/outlet to avoid eccentric torque. Use pipeline supports to prevent the pump body from bearing pipe weight, which may cause leakage or structural damage.
