Smith Pumps -  E Series Small Capacity Stationary Pumps

Designed for direct motor mount to the 56C-frame electric motor or to internal combustion engine for portable transfer applications. Each E-series pump comes complete with an internal/external bypass valve and built-in strainer. Affords the flexibility of either using the pump bypass valve to relieve within the pump in cases where it is necessary or with a simple rotation of the pump cover, the internal bypass valve can be used as an external bypass valve with the use of a return line back to the supply tank. The bypass valve cartridge is set to crack at 90 psid. Replacement parts for E-series are interchangeable with D-series. Foot mount available. .
