HORIZONTAL VC PUMPS

Horizontal VC pumps

Description

Horizontal multistage pumps are designed to pump clean cold or hot water with a temperature of up to 130°C. They are useful for supplying residential houses and settlements with water or for pumping process water. They are installed in irrigation systems, hydrophore devices, hydrant networks or hot water systems. In technological processes, they are useful for pumping all chemically neutral liquids that do not contain abrasive particles with a viscosity similar to the viscosity of water.

Horizontal multistage pumps are made in a monoblock version with a common shaft of the electric motor and the pumping part (the pumping part with castings made of gray cast iron and brass). Each stage of the pumping part consists of an impeller, a guide and a stage housing. The housings are sealed with seals. Pump shafts (VC…S) are sealed with mechanical seals. The pressure connections of the pumps are equipped with an internal thread. The suction connections of the pumps are made without internal flanges with an internal thread in the pump cover. The drive motors are air-cooled three-phase motors with IP54 degree of protection and insulation class F. The electric motors have built-in radial closed bearings. Motors with power up to 2.2kW are intended for direct start, and motors with power up to 3kW and more are designed for soft (y/Δ) start.
