Waukesha Sanitary Positive Displacement Pumps


Waukesha Pumps       Waukesha sanitary positive displacement pumps are the most efficient on the market. This is made possible in part by Waukesha’s External Circumferential Piston (ECP) technology.  The basics of which operates on the principle of two counter rotating ECP rotors.  The constant velocity caused by the turning of these rotors combined with its shape allows for a constant volume per unit flow.  In order for this technology to perform well, precise pump clearances are needed.  The following effect precise clearances in a Waukesha pump:

Rotor Location          Bearing           Forces on Body

Timing Gears            Shearing         Temperature

ECP pumps can be used on low to high viscosity products.  It consists of a metered flow and high pressure capabilities.  An ECP Waukesha pump can handle particulates and can be used for shear sensitive products.  It also requires less horse power than centrifugal pumps for viscous flow rates.
