Vertical, centrifugal, single-stage pump, with single entry impeller located between bearing supports

General characteristics:
  • Pump type Centrifugal
  • Installation method Vertical
  • Flow 3000 – 90000 m³/h
  • Pressure range 30 - 140 m
  • Efficiency up to 93%
Purpose of the equipment:

Pumps of the V-DVN series are designed for pumping water and liquids similar to it in main and auxiliary pipeline systems, including in the food industry, with an ultimate pressure of up to 2.5 MPa

Design features of the equipment:
  • The axial force generated in the pump is hydrodynamically compensated, the residual axial force is absorbed by the pump bearings and is not transmitted to the electric motor
  • Highly efficient, AI-designed, corrosion-resistant wet end
  • Impeller type - closed for maximum efficiency
  • A hard-alloy segment plain bearing is installed in front of the impeller, designed to absorb the residual radial force. The impeller is located between the bearings.
  • The main pump bearings are rolling bearings lubricated with automatic grease lubrication
  • Operation of bearing units - more than 50,000 hours
  • Vibration of the pump in the nominal mode does not exceed 2 mm/s, and within the limits of the operating interval of supply does not exceed 3 mm/s
  • The wear rings are made of wear-resistant material, which significantly increases their service life.
  • Mechanical seal unit of modular design, the design provides for the possibility of replacing mechanical seals with stuffing box
  • When pumping river water, the pump is additionally equipped with a hydrocyclone cleaning system for the auxiliary line of the mechanical seal
