VCV-I vertical multistage pumps
VCV-I vertical multistage pumps
Description
Vertical 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.
Technical characteristics
Flow: from 30 to 350 l/min
Lifting pumping height: up to 170m
Motor power: 0.75 ÷ 6.7 kW
Power supply: 3-phase (400V)
Medium temperature: from 0°C to + 130°C
Ambient temperature: from 0°C to + 40°C
Suction height: up to 7m
Maximum permissible operating pressure of the housing: 20bar
Weight: 25 – 112kg
Vertical multistage pumps are made in a monoblock version with a joint shaft of the electric motor and the pumping part, wherein the pumping part and all parts in contact with the medium are made of stainless steel. Each stage of the pumping part consists of an impeller, a guide and a stage housing. The housings are sealed with seals. The pump shafts are sealed with mechanical seals. The pressure and suction connections of the pumps are equipped with internal threaded flanges. 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.
