Pump Specs

The Simple Pump  is made from lead-free, stainless steel and aluminum components. (Aluminum is never in contact with water.)

All components are Safe Drinking Water Act compliant.

Simple Pump  is designed with very few points of wear: the u-cup seals on the piston and the rod seals in the pump head.
