Description

Design

Chemical-resistant stainless steel centrifugal pump in close-coupled design, with single-acting mechanical seal

Features

Robust and durable construction made of thick-walled, solid stainless steel components

  • Also suitable for liquids with a light solids load due to spring-loaded mechanical seal
  • Low-maintenance operation thanks to high-quality sliding surface materials
  • All media-contacting parts made of high-quality, corrosion-resistant stainless steel 1.4571 (AISI 316Ti)
  • Equipped with threaded connections to ISO 228-1 as standard, optionally available with flange connections from size 130 upwards
  • Universally applicable, compact and quiet
  • Approved for use in potentially explosive environments (ATEX Zone 1)
  • Corrosion-resistant paint finish in RAL1017, saffron yellow

 

Areas of application

Pumping salt water, weak acids and alkalis or other corrosive liquids. Pumping of water- or oil-based emulsions at temperatures up to 150°C. Used in harsh environments and in applications where a particularly robust pump is required.

For example in the following applications:

  • Conveying coolants and heat transfer oils in cooling or temperature control units
  • Electroplating and surface coating
  • Waste water and fresh water treatment
  • Paper industry
  • Laboratory and medical technology
  • Environmental technology, exhaust gas purification and gas scrubbers

Technical data

UP centrifugal pump

NORMAL-PRIMING CENTRIFUGAL PUMPS

WITH SINGLE-ACTING MECHANICAL SEAL

  • Housing and impeller material: Stainless steel precision casting 1.4571 (V4A)
  • Elastomer materials: EPDM, FKM (e.g. Viton®), FEP, FFKM (e.g. Kalrez®)
  • Mechanical seal materials: SiC (silicon carbide), graphite carbon, PTFE-GF, Al2O3 ceramic
  • Media-contact metal parts: Stainless steel 1.4571 (V4A)

The UP series is the counterpart to the U series for applications where the use of a plastic pump is not possible, e.g. due to increased temperature requirements of up to 150°C. It is equipped with a single-acting mechanical seal that is lubricated and cooled by the pumped medium. Sliding rings and elastomers are available in various materials, the spring is made of Hastelloy® C4.

 

Advantages:

  • Robust and durable construction made of thick-walled, solid stainless steel components
  • Compact block design
  • Simple installation
  • Suitable for high temperatures

Solids up to 3 mm grain size and 10 % by volume can also be transported. The viscosity can be up to 150 mPas, the maximum media temperature, depending on the version, is 150°C. All sizes are also available in ATEX-certified versions under the designation UP-EX for use in ATEX zones 1 and 2.
