Waukesha Universal 3 Sanitary PD Pump
Overview
The Waukesha Cherry-Burrell Universal 3 Series PD pump is the latest addition to the Waukesha positive displacement pump family. Offerings a front loading seal, there are no bearings in the product zone. With operating pressures up to 500 PSI and standard 316L body and 304SS gearcase, there a Universal 3 for every process condition. Assembled and tested in Delavan, WI, the Universal 3 offers the same great performance and reliability SPXFlow is known for.
Features
Univeral 3 Pump Features include:
-
Up to 500 psi (34.5 bar) pressure capability
-
Pumps rated to 300F (149 C) as a standard
-
Special rotor nut designed for extended service without loosening
-
No bearings in the product zone
-
New shafts are shorter and have larger diameter 17-4 PH shafts:
-
Reduces overhung load which improves shaft alignment and decreases seal and bearing wear for extended seal life.
-
Improves shaft strength and sitffness helping to eliminate vibration
-
-
Heavy duty stainless steel bearing frame standard
-
Double tapered roller bearings
-
Greased lubed bearings for positive lubrication to all bearings over entire speed, temperature, and pressure range
- Body retaining screws for maintaining mechanical seal contact during inspection
- Extended out seal life. A wave spring, instead of an o-ring, mechanically loads the seal
- Unique mechanical seal design utilizes 2 pin stationary seal and special design shaft for rotary seal
- Pump for Life Lifecylce Program
Theory of Operation
The Waukesha Universal Series of pumps use the time-tested circumferential-piston operating principle. The arc-shaped "pistons" (rotor wings) travel in annular-shaped cylinders machined in the pump body; the resulting long sealing path reduces slippage and produces a smooth flow of product without destructive pulses or pressure peaks and without valves or complex parts.
Because the rotors are made of Waukesha non-galling Alloy 88, the rotors can be run with exceptionally close clearance with the 316L stainless steel fluid head, without having to fear galling or seizing should inadvertent pressure surges cause contact. The close clearances combined with the rotor geometry, which gives a long sealing path between the pump inlet and outlet, means low slip operation even with low viscosity fluids. This means you get high efficiency, good priming ability, metering capability, and flow control everytime you use a Waukesha Universal Pump.
Additionally, because of the large fluid cavities in the rotors, plus the large, easy entry anti-cavitation ports, the Universal Series of pumps allow efficient pumping of high viscosity fluids, slurries, or even liquids with large chunks or particles.
Finally, because the Waukesha Cherry-Burrell design has no bearings in the fluid being pumped, no sliding or rolling contact and no rotor-to-rotor contact, we get excellent service with every Universal Positive Displacement pump even under sever or abrasive conditions.
