Progressive Cavity Pumps

Fluid Research® progressive cavity pumps deliver precise, consistent, and reliable dispensing of a wide variety of fluid media. These pumps are included in many of our systems with accurate precision dispensing achieved independent of media viscosity. Each pump exhibits exceptional resistance to abrasive/filled content and chemically aggressive fluids.

Suitable for single or multi-component applications, Fluid Research® pumps are precision-made in the USA, available in seven models. Operational advantages include: constant volume at variable speeds, continuous flow, few moving parts, low maintenance, and no cycle time delays for cavity recharge. Specific design features of progressing cavity pumps provide additional functional benefits. The cavities taper down toward their ends and overlap with their neighbors, essentially eliminating flow pulsation. No flow meter or check valves are required due to the seal design of progressing cavity pumps.
