DVP4

(VS4 API 610)

The range of vertical semi-submersible cantilever single-casing pumps with a volute discharge. The liquid passes to the discharge nozzle through a separate column specifically engineered for the efficient pumping of aggressive and high-viscosity liquids.

a plate-type coupling with a spacer provides seal replacement without detaching the pump body from the pipeline;
a mesh filter on the suction side prevents external contamination, extending the lifespan of the seals;
the sliding bearings in the submersible part of the pump, lubricated by the pumped medium, are located along the column and eliminate the need for lubrication or cooling of intermediate bushings with system fluid;
the modular pump construction allows the selection of the optimal pump configuration;
can be manufactured to individual specifications with a heating system for pumping high-viscosity liquids such as bitumen, tar, fuel oil, and other similar fluids in terms of physical and chemical properties;
