WHERE TO BUY

Universal 3 Series: Hygienic Pumping Power for Food & Beverage Excellence

The Universal 3 Series is the latest addition to the Waukesha positive displacement pump family by SPX FLOW. Designed for hygienic applications in the food and beverage industry, it features a front-loading seal design with no bearings in the product zone. With operating pressure capacities up to 500 psi (34.5 bar) and a standard 316L stainless steel body and cover, it offers a robust and sanitary fluid transfer solution.

Assembled and tested in Delavan, WI, the pump includes "Waukesha 88" non-galling rotors and a standard 304 stainless steel gear case—engineered to withstand the rigors of daily processing environments.

Long-Life Features

Diffusion-hardened surfaces for rotor, body and cover available - ideal for abrasive or corrosive environments (3-A / FDA compliant)
Up to 500 psi (34.5 bar) pressure capability
Rated to 300°F (149°C) as standard
Special rotor nut designed for extended service without loosening
No bearings in the product zone
Shorter, larger diameter 17-4 PH shafts:
- Reduces overhung load, improving shaft alignment and decreasing seal and bearing wear
- Improves shaft strength and stiffness to eliminate vibration
Heavy-duty stainless steel bearing frame (standard)
Double tapered roller bearings
Grease-lubricated bearings for consistent lubrication across all operating conditions
Body retaining screws maintain mechanical seal contact during inspection
Wave spring mechanically loads the seal for extended outer seal life
Unique mechanical seal design with 2-pin stationary seal and specially designed shaft for rotary seal
