Positive Displacement

A positive displacement pump works by causing a fluid to move by trapping a fixed amount, then forcing (displacing) it to the discharge pipe.

Positive Displacement

These pumps can be used for all types of fluids, including those that are of high viscosity. There are several types of positive displacement pumps including internal gear, external gear, rotary lobe, diaphragm, and progressing cavity. Cullum & Brown can supply any of these pump types to best fit the application requirements. We represent some of the leading manufacturers in this industry, providing you more than one choice for your application. No matter what type of positive displacement pump you desire, we have a solution for you.
