Series U

Chemically resistant, single-stage centrifugal pump in close-coupled design, with single mechanical seal

The U series is the basic model for pumping aggressive fluids. In the U series, the motor power is transmitted directly to the pump impeller via a continuous shaft (close-coupled pump). A single mechanical seal, lubricated and cooled by the process fluid, ensures pump tightness. The mechanical seal is available with various elastomer and sliding face materials.

The U series is a versatile all-round pump. Its wide range of designs and materials allows optimum adaptation to a broad variety of process fluids and operating conditions. Solids with a particle size of up to 3 mm and a concentration of up to 10 vol.% can be conveyed. The viscosity can be up to 150 mPa·s, and the maximum fluid temperature is 95 °C. All sizes are also available in ATEX-certified versions under the designation U-EX for use in ATEX Zone 2.

Chemically resistant, single-stage centrifugal pump in close-coupled design, with single-acting mechanical seal

Features

  • Cost-effective and robust alternative to magnetic drive pumps
  • Also suitable for fluids with light solids loading due to the spring-loaded mechanical seal
  • Suitable for conveying ferromagnetic particles
  • Low-maintenance operation due to high-quality sliding surface materials. All wetted parts are made of high-grade, corrosion-resistant materials
  • Equipped as standard with threaded connections according to ISO 228-1; from size 130 also available with flange connections as an option
  • Versatile, compact and quiet
  • Corrosion-resistant coating in RAL1017, saffron yellow
  • All screws made of V4A stainless steel (1.4571)




Applications

Pumping of acids, lyes or other corrosive, hazardous or toxic fluids in applications where leakage of even the smallest quantities is undesirable and a hermetically sealed pump is required.

Pumping of high-purity or sensitive fluids where contamination of the process fluid with foreign substances must be avoided.

For example in the following applications:

  • Industrial and municipal wastewater treatment
  • Electroplating and surface coating
  • Laboratory and medical technology
  • Environmental technology, exhaust gas cleaning, gas scrubbers
  • Battery production, energy storage
  • and many other applications
