Submersible pumping station SN-R1-03

Submersible pumping station SN-R1-03 are intended to:

to pump abrasive hydraulic fluids (clay and gravel mortars, mixtures of water and sand, ore, etc.);
to swamp drainage, unwatering of foundation, drainage of lakes and other water bodies;
to bottom dredging, bank alluviation, desliming and etc;
for maintenance and repair of gas pipelines in swampy and flooded areas;
for pumping drill cuttings (cuttings slurry, waste drilling mud), blackwater, industrial waste-water, oil contaminated soil, process effluent of oil-production enterprise and oil refinery;
for pumping domestic and industrial wastewater with long-fibre, coarse and solid inclusions.
