The pumps NHV are intended for pumping of pure liquids or liquids with trace pollution with low degree of viscosity.
The pumps nhv find application in:
- systems of water supply and water systems
- systems of water treatment and water purification
- klimatizatsionny systems
- cellulose industry
- chemical and petrochemical industry
- fire-prevention installations
- power plants
|Productivity||to 1700 m3/h|

The pumps NHV it is one-stage, centrifugal, normalnovsasyvayushchy lopasty pumps with a horizontal axis of a shaft. The main sizes and parameters correspond the EN 733 standard.
The soaking-up branch pipe and pressure head branch pipe correspond the ISO 7005-2/PN 16 standard.
Due to the use of special modular system all bearing system together with a rotor and the case can understand without the need for dismantle of all installation.
All rotors statically are also dynamically balanced respectively by the ISO 1940 standard a class 6.3. Load of an axis is balanced through use of system of rings and the balancing openings.
