Horizontal, centrifugal, single-stage pump, with a horizontal casing split and a double-sided impeller located between the bearings.

General characteristics:
  • Pump type Centrifugal
  • Installation method Horizontal / Vertical
  • Flow 1250 - 25000 m³/h
  • Pressure range 21 - 180 m
  • Efficiency up to 93%
  • API-610 classification BB1
Purpose of the equipment:

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

Design features of the equipment:
  • Spiral split housing minimizes hydraulic radial forces in any condition down to minimum flow
  • The main pump bearings are rolling bearings, lubricated with synthetic grease, without connecting external cooling sources, without the use of roller thrust bearings
  • Special purity of lubricants due to the use of lip seals of bearing units
  • The sealing of the main connector of the body is realized using an asbestos-free gasket material based on aramid fibers
  • Rotor balancing class G0.4 according to GOST ISO 1940
  • The pump rotor can be made in a symmetrical design, for the possibility of installing a drive motor both on the left and on the right side
  • Vibration of the pump in nominal mode - no more than 1.5 mm/s, and within the limits of the operating interval of feeds - no more than 3 mm/s
  • The use of anti-corrosion surfacing technologies, high-speed laser spraying and special labyrinth profile grooves in replaceable rings of slotted seals make it possible to obtain high resistance to the flow of the pumped liquid while maintaining durability
  • Pump wear rings - with additional installation of rubber seals between the pump housing and the wear ring
