Features & Benefits

High Volume, Lower Cost, CIP

The new Universal Lobe Pumps were specifically designed for a different challenge: lower cost and CIP (clean in place) applications. While intended for lower cost, Universal Lobe Pumps are not “light duty.” They incorporate the advanced technology of the new Universal II PD that strengthens sanitary performance and extends pump life. They are capable of accommodating high temperatures and pressures up to 300 psi (20.7 bar). Universal Lobe Pump Series utilize the Universal II gear case with 3-way mounting flexibility. It offers the full range of seal and port options and has Integral Speed Reducer (ISR) mounting capabilities.

Sanitation Features

• CIPable. Pump body has an internal flat profile and is free draining with vertical ports.
• Cover is free draining in horizontal or vertical port positions.
• Rotor/shaft connection sealed from product zone.
• Exclusive, non-galling Waukesha “88” alloy rotors standard; permits running at tighter clearances and higher efficiencies; 316 stainless steel lobe rotors also available.
• Mechanical seals standard. Single or flushed double.
• Seal flush optional: seal areas interconnected to improve circulation and draining of seal flush fluid. Steam-In-Place also is optional.
• Jacketed cover optional.
• 316 stainless steel pump body and cover; 316L optional.
• Electro-polish of product contact surfaces, optional.
• Stainless steel bearing frame optional.

Long-life Features

Precision rotor movement virtually eliminates vibration; extends seal life.

• Rotor nut designed for extended service without loosening.
• No bearing in product zone.
• Larger diameter shafts in seal area for greater strength and stiffness.
• Heavy duty bearing frame (stainless steel available as an option)
• Double tapered roller bearings on all models. Contribute further to precise rotor movement and longer seal life.
• 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 outer seal life. A wave spring, instead of an o-ring, mechanically loads the seal.
• O-ring on inner seal, seals on clean surface as seal moves due to wear.
• 3 full-radius drive pin grooves reduce stress/increase durability of seals.

Installation Flexibility

• Bidirectional flow. Rotors, locked with belleville washers and torqued nuts, rotate securely in either direction. No more flow direction/shaft position specification.
• Interchangeable installation dimensions with Universal and Universal II PD pumps.
• Versatile 3-Way mounting of gear case, including vertical alignment of ports.
• Upper or lower shaft position.
