Frequently asked questions

The pressure relief valve helps prevent over-pressurization of the pump, which can damage the pump and cause serious injury. It can also be used to adjust flow rates.

It is important to inject a small amount of fluid into the pump inlet prior to starting the pump. This helps the pump self-prime and prevents the loud screeching noise that can occur if the gears are completely dry.

If your pump is decoupling at startup, check for solids stuck in the gears or for restrictions in the inlet/outlet lines. Reduce the motor speed if the fluid viscosity is too high.

Do not allow the fluid to freeze in the pump. Avoid operating the pump outside the temperature limits set forth in the manual and the pump’s individual specification sheet.
