MKP-S – Stainless Steel Self-Priming Magnetic Drive Chemical Process Pump

Back to Product Guide

  • Pump dimensions to DIN EN ISO 2858, ANSI/ASME B73.3
  • Compact design with virtually no dead areas, allowing easy and efficient heating
  • Hydraulically balanced impeller for minimum bearing loads
  • Internal and external bearing lubrication and flush options
  • Integral priming chamber for high reliability and safety
  • Solids handling capability up to concentrations of 30% and a particle size of 1 mm depending on the pumped fluid
  • Self-priming with suction lift up to 8.5 m
  • Ideal for efficiently emptying tanks that have no bottom drain
  • Available with a double-walled jacketed discharge pipe
  • Modular system consisting of just a few components, easy assembly
