DHV pumps should be applied for pumping of clean or slightly contaminated liquids with low viscosity and temperature up to 120oC.
The main applications are:
- water supply, water treatment stations,
- irrigation systems,
- water heating and water cooling systems,
- industrial water systems,
- fire fighting systems,
- power plants,
- seawater pumping systems.
Features
- Pumps type DHV are characterized by high rigidity of hydraulic system thanks to supporting of the shaft from its both sides.
- Due to central location of impeller on the shaft and sucking of water by the impeller from its both sides, the axial forces In the pump have been reduced to the minimum what allows for simple pump bearing and elongates its life considerably.
- Pump casing, divided in two halves (upper and bottom) allows for very convenient and easy inspection and reapairs of hydraulic system, after removing of the upper half.
- Pumps are characterized by high efficiencies and low operation costs.
- Due to big number of pump types and their very wide operation range, optimum selection of pumps for set operation parameters is possible.
TECHNICAL DATA
- Capacity Q: up to 12000 m3/h
- Delivery head H: up to 220 m
- Temperature of pumped liquidy t: up to 120oC
Construction
Pump casing - axially splitImpeller - close, double suction
Shaft - protected by shaft sleeves
Sealing - soft packing - standard execution. Mechanical seal ( e.g. J. Crane, Burgmann, Anga) - on demand.
Bearings in this type of pump axial force is reduced to minimum thanks to this radial ball bearings - grease lubricated are applied as a standard, oil lubricated on demand. All rotating elements are dynamiclly balanced and vibration free.
Speed - pump operates with the wide range of seed; from 2900rpm to 500rpm. Pumps may be controlled by Frequency Converters at different speeds or driven by other then electric motors.

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.
We encourage you to create an account and try our program.
