Rotary Positive Displacement (Lobe) Pumps

New Sanitation Features

1.CIP capability available. Pump body has optional internal flat body profile
   and will free drain with vertical ports. Optional rotor and body hub drilling
   provided for difficult CIP cleaning applications.
2.Cover is free draining in horizontal or vertical port positions.
3.Rotor/shaft connection sealed from product zone.
4.Single mechanical seals standard. Optional double mechanical seals also
   available.
5.Seal flush optional: seal areas interconnected to improve circulation and
   draining of seal flush fluid. Steam-In-Place also is optional.
6.Stainless steel bearing frame optional on models 006 to 220.
7.Aseptic Design (Option)

Long-life features

1.Up to 500 (34.5 bar) psi pressure capability.
2.Special rotor nut designed for extended service without loosening.
3.No bearings in the product zone.
4.Larger diameter 17-4 PH shafts for greater strength and stiffness. Helps
   eliminate vibration; extends seal life.
5.Heavy duty bearing frame (stainless steel available as an option).
6.Double tapered roller bearings.
7.Greased lubed bearings for positive lubrication to all bearings over entire
   speed, temperature and pressure range.
8.Body retaining screws for maintaining mechanical seal contact during
   inspection.
9.Extended outer seal life. A wave spring, instead of an O-ring, mechanically
   loads the seal.
10.O-Ring on inner seal, seals on clean surface as seal moves due to wear.
11.Unique mechanical seal design utilizes 3 pin stationary seal and special
    design shaft for rotary seal.


Installation flexibility

1.Bi-directional flow. Rotors, locked with belleville washers and torqued nuts,
  rotate securely in either direction. No more flow direction/shaft position
  specifications.
2.Interchangeable installation dimensions with Universal I and
3.Universal Lobe PD pumps. (Except for 320 and 324 sizes)
4.Versatile 3-Way mounting of gear case, including vertical alignment of ports.
5.Upper or lower shaft position.
6.Jacketed or vented cover optional.
7.Exclusive, non-galling Waukesha 88 alloy rotors standard; permits running
   at tighter clearances and pumping a wide range of viscosities. 316 stainless
   steel lobe rotors also available.
8.316 stainless steel pump body and cover; 316L optional.
9.Electro-polish of product contact surfaces, optional.
