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.

Waukesha Universal III Sanitary Pump

 

        The Waukesha Universal 3 Series is the latest addition to the Waukesha positive displacement pump family by SPX FLOW. It offers a front loading seal design with no bearings in the product zone. Operating pressure capacities up to 500 psi (34.5 bar) and standard 316L stainless steel body and cover makes this an attractive hygienic pump option for your most challenging applications in the food and beverage industry. Assembled and tested in Delavan, WI with “Waukesha 88” non-galling rotors and a standard 304 stainless steel gear case provides an ideal fluid transfer solution that is able to withstand the rigors of daily processing environments. Other characteristics include:

  • Up to 500 psi (34.5 bar) pressure capability 
  • Pumps rated to 300°F
  • Special rotor nut designed for extended service without loosening
  • No bearings in the product zones
  • New shafts are shorter and have larger diameter which improves shaft alignment and decreases seal and bearing wear for extended seal life
  • Extended outer seal life. A wave spring, instead of an O-ring, mechanically loads the seal
