Main-line pumps (SE)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
