U2 Universal 2 Series Pump

The U2 Universal 2 rotary positive displacement pumps from SPX FLOW Waukesha Cherry-Burrell are a great option between the legacy U1 series pumps and the newest SPX FLOW ECP pump, the U3 series pumps.

The U2 pump series offers improved hygienic performance and even more longevity features than the original U1 pump series. These were the industry standard for ECP pumps until 2018 when the newest U3 series hit the market. The U2 series offered substantial design improvements and is a serious heavy-duty upgrade to the U1 series where more reliability and improved hygienic performance are demanded.

Key Sanitary Features Include:

  • CIP capability is available for all models
  • The pump body has an optional internal flat body profile, which allows it to free-drain with vertical ports
  • Optional rotor and body hub drilling provided for challenging CIP cleaning applications
  • The cover is free-draining in the horizontal or vertical port positions
  • The rotor/shaft connection is sealed from the product zone
  • Optional double mechanical seals are available
  • Seal flush is optional. The seal areas are interconnected to improve circulation and draining of seal flush fluid
  • Steam-In-Place is also optional
  • Stainless steel bearing frame optional on models 006 to 370
  • Aseptic design is available
Key Reliability and Long-Life Features Include:
  • Up to 500 psi (34.5 bar) pressure capability. Compares to 200 psi for the U1 pump series
  • No bearings in the product zone
  • Large diameter 17-4 PH shafts for greater strength and stiffness, improving seal reliability
  • Heavy-duty bearing frame (stainless steel available as an option)
  • Double tapered roller bearings
  • Greased lubed bearings for positive lubrication to all bearings over the 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
  • The O-Ring on the inner seal seals on a clean surface as the seal moves due to wear
  • Unique mechanical seal design utilizes a 3-pin stationary seal and a special design shaft for rotary seal.
Applications for the Universal 2 pump series include:
  • Food and Beverage
  • Pharmaceutical
  • Dairy
  • Chemical
  • Industrial
