Equipment details

Slurry Pump Basic

VASA HD Series horizontal slurry pumps are an excellent choise for applications where the smallest Metso MD Series or X Series pumps are too large.

Furthermore, VASA HD pumps are well suited for when a higher maximum pump operating pressure is needed.

  • Flow rates to 4 100 m³/h 
  • Heads up to 63 m
  • Maximum operating pressure 25 bar – 360 psi

Typical applications

  • Mill discharge
  • Hydrocyclone feed
  • Tailings disposal
  • In plant slurry transfer pumps

Design

The shaft with its oversized roller bearings is assembled in a cartridge type bearing housing which is bedded in a fabricated pump frame.

The stuffing box housing is attached to the same pump frame to assure total concentricity between shaft and sealing arrangement.

The impeller is fixed to the shaft by a taper and a key, assuring safe attachment even at reverse rotation and still providing easy replacement.

The vertically split casing allows operation of up to five pumps in series with standard pumps.

Shaft sealing arrangements are gland packed, water-flushed stuffing box or dynamic “expeller” seal. Both alternatives supported by pump-out vanes on the impeller. The stuffing box version has a double protection against slurry entering.
