Positive Displacement Pumps Solve Ice Cream Mix System Issue

The SPX Waukesha series of positive displacement pumps include advanced sanitation technologies, long-life features, and installation flexibility. They are also Clean-in-Place (CIP) capable that are engineered to perform in food & beverage, dairy, pharmaceutical, and personal care industries.

      • Key Features & Benefits

        • 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.
        • Cover is free draining in horizontal or vertical port positions.
        • Rotor/shaft connection sealed from product zone.
        • Single mechanical seals standard. Optional double mechanical seals
          also available.
        • Seal flush optional: seal areas interconnected to improve circulation
          and draining of seal flush fluid. Steam-In-Place also is optional.
        • Optional aseptic design

        Long-Life Features

        • 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 outer 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

        Success Story:

        Waukesha Brand – Model 130 Universal 1 Series

        Industry: Ice Cream Mix

        Problem: Premature failure of rotors and shaft parts

        Solution: A large US-based dairy installed an ice cream mix system using two Waukesha model 130 Universal 1 series pumps with the help of SPX; one as a feed pump and the other as a pullout pump for a dry/liquid blender.

        The plant was interested to reduce the cost of ownership of the rotary lobe pumps from a previously installed system. The pumps used in the original system required complete rotor replacement every 6 months.

        The External Circumferential Piston (ECP) style rotors, with larger crossover clearances and higher efficiency, were able to stand up to the plant’s demanding performance requirements and eliminate their pump downtime. As an added benefit, SPX’s simple, economical single O-ring shaft seals provided an alternative to the more expensive and sensitive mechanical seals offered on the originally installed pumps.
