Frequently asked


1 What if I mix several chemicals together. Can I use the individual material to chemical ratings that are listed in the chemical resistance chart to transfer this fluid mixtures?

Proceed with caution. Individual ratings may or may not be appropriate for a chemical cocktail. Again, is the fluid currently being transferred successfully using a particular set of materials.

2 How often should I tighten fasteners on my plastic pumps?

That depends on the application. Pressure, average hours in service, and temperature all affect the flow of plastic. Pumps need tightening if leakage should occur. Tightening should be part of any preventive maintenance program and should be based on the service duty of the pump.

3 Do I have to ground the pump when pumping flammable fluids?

Yes. This can be done with conductive plastic pumps via the grounding lugs. If you are not using a conductive plastic pump then ground the fluid through a metallic pipe nipple at both the suction and discharge ports. Metal pumps should also be grounded.

4 How does high specific gravity affect my pumping application?

If the pump is flooded, fluids with high specific gravity may exceed the pump suction limitations of 10psi. If the pump is above the level of the fluid, high specific gravity will limit suction lift.

5 Do all pumps have dual manifold capability?

All 1/4”, 3/8” and 1/2” pumps can be configured at the factory for dual manifolds.
