100% Tested

Every pump is fully tested to verify performance prior to shipment.

Volatile Fluid Handling

The turbine impeller handles vapors in excess of 20% by volume, minimizing the possibility of vapor lock.

“O”Ring Gaskets

“O”ring gaskets are used throughout the T31 Series pumps to assure positive sealing.

Extended Reliability Motors
