Main-line pumps (SE)

Designation: pumps SE type are designed for pumping in heating pipe networks with temperatures up to 180ºС

Design: pumps network SE - centrifugal, horizontal, volute with horizontal connector housing, one- and two-stage with transfer pipes with double-entry impellers. Rotor bearings are outrigger bearings with crankcase lubrication. Shaft seals - mechanical with gland packing with cooling and locking liquid supply (-C), interchangeable with mechanical face (-T).

Materials:

  • body, covers - cast iron
  • impeller – chromium steel 20KH13L
  • slot seals details - indelible corrosion-resistant alloys
  • shaft - structural alloy steel 40KH

Completeness:

  • pump assembled with auxiliary piping within the pump
  • counter flanges on the branch pipes
  • drive motor
  • coupling type MUVP or MUP with fencing
  • common or separate foundation frames (depending on the pump size)
  • pump, engine and clutch fencing parts
  • spare parts kit
