WAUKESHA PUMPS – UNIVERSAL II INDUSTRIAL SERIES – POSITIVE DISPLACEMENT PUMP

“Universal II Industrial – Overview”

 

• 316L stainless steel pump body and cover (standard).

• Exclusive, non-galling Waukesha “88” alloy rotors standard; permits running at tighter clearances and pumping a wide range of viscosities. 316L stainless steel rotors also available.

• No internal rotor contact eliminates need to rely on pump fluid as a lubrication.

• Rotor/shaft connection sealed from product zone.

• Mechanical seals standard. Options include single, knife edge, low pressure flush, and high pressure barrier double seals.

• Up to 500 (34.5 bar) psi pressure capability.

• Rotor nut designed for extended service without loosening.

• No bearings in product zone.

• Larger diameter 17-4 PH shafts in seal area for greater strength and stiffness. Helps eliminate vibration; extends seal life. 316SS optional.

• Heavy duty cast iron bearing frame. (Stainless steel available as an option)

• Double tapered roller bearings on all models. Contribute further to precise rotor position and longer seal life.

• Grease 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.

• Remanufacturing Program to extend life and reduce costs.

• Pumps filled with most settled slurries will start without damaging pumps or seals.

• Expanded fluid cavities can pump liquids with large solids without jamming or knocking rotors out of timing.

• Very low shear, product not damaged during pumping.

• No internal rotor contact.

• Requires less horsepower than Progressing Cavity Pumps

• Unique timing gear arrangement reduces troublesome maintenance issues as experienced on conventional lobe pumps

• No cross contamination of lubricating oil into product zone due to unique gear case design.

• Pumps are energy efficient, and easily cleaned, maintained, and repaired.

 

Options

• Composite Diamond Coating (CDC) for abrasive service

• External over pressure valves for full flow relief.

• Bearing isolators.

• Tru-Fit integral gear motor drives.

 

Installation Features

• Bi-directional flow. Rotors, locked with unique washers and torqued nuts, rotate securely in either direction.

• Interchangeable installation dimensions with Universal 1 and
Universal Lobe PD Series pumps.

• Versatile 3-Way mounting of gear case, including vertical alignment of ports.

• Upper or lower drive shaft position.
