Stainless steel submersible multistage clean water pumps MXS
Design
Submersible multistage pumps made of stainless
chromium-nickel steel
Hydraulics at the bottom and motor at the top, cooled by the
pumped water to ensure reliable operation even
when the pump is partially submerged.
Double seal on the shaft with inserted oil chamber.
The suction filter prevents
solids larger than:
- 2.5 mm for MXS 203,204,205,206,404,405,803,804
- 2 mm for MXS 207,8,9,10 - 406,7,8,9,10 - 805,6,7,8, nine.
Application
Water supply from wells, baths or reservoirs. Use in everyday life, industry, gardening and irrigation. Rain water recycling.
Operating restrictions
