Horizontal multistage stainless steel centrifugal pump

CHM

New-generation light horizontal multistage pumps, CHM1 to CHM20

Non-self-priming horizontal multistage pumps with a compact extended-shaft motor design. The liquid enters axially and leaves radially. The flow passage is stamped and welded stainless steel (304L or 316L), giving high efficiency, low noise, light weight and easy installation and maintenance.

  • Rated flow 1–20 m³/h, up to 9.6 bar pump pressure
  • Liquid -15 to +70 °C; hot-water type up to +105 °C
  • Threaded G1 to G2 connections, stainless flow passage
  • Air conditioning, cooling, industrial cleaning, water treatment, aquaculture
