Hydro-Vacuum S.A. - Single-stage, centrifugal pumps type NHV

The NHV pumps are single-stage, centrifugal, normally sucking, impeller pumps with horizontal shaft axis
Main dimensions and rated parameters conformable to EN 733.
Suction and discharge fl anges comply with ISO 7005-2/PN 16.

Due to special modular design, the whole bearing unit, including the impeller and casing, can be removed without the need to dismantle the system.

All impellers are statically and dynamically balanced according to ISO 1940, class 6.3. Axial thrust is balanced by using a system of rings and balance openings.

Application:

water supply systems and water mains,
water treatment plants,
air-conditioning systems
cooling systems
pulp and paper industry
chemical and petrochemical industry
fire-fighting systems
power plants

OPERATION AREA

Hydro-Vacuum S.A. Pump Selection Progam.

Quick and simple online tool for pump selection based on set criteria.

Thanks to the PDP, by means of the "Hydraulic Selection" function, specific pumps can be selected by configuring, among other things, the area of application, pump type, pump design, medium to be pumped, operating point, etc. Alternatively, by using the "Product Catalogue", you can conveniently browse through the pump catalogue which is Hydro-Vacuum S.A. 's production offer.

The result of the selection is a data sheet for the pump containing all the necessary hydraulic (characteristics), electrical, material, construction, dimensional, etc. data.

The first thing to do is to register a new account. After entering some necessary data and approving the form, an activation link will be sent to the e-mail address provided. After clicking on the link, you will be able to make full use of the Hydro-Vacuum S.A. Pump Selection Software.
