  • Page 24: Description Of Operation

    Slurry Pump DESCRIPTION OF OPERATION General Centrifugal pumps work best with minimum wear and other mechanical stress if the operating point is close to the pump's best efficiency point (BEP). To choose a pump that works close to its best efficiency line (BEL), it is important to understand how the pump interacts with the piping system in which it is installed.
  • Page 25 Slurry Pump When the pump operates at When the pump's flow The magnitude of the radial best efficiency point, uniform capacity is not utilized, force F is greatest when the pressure is obtained in the uniform pressure in the pump runs against closed casing which in its turn pump casing will not be valve = 0 flow.
  • Page 26 Slurry Pump The way in which the hydraulic work is affected when the pump does not operate at BEP is shown in Figure 4.3-2 and Figure 4.3-3 This is of decisive importance in slurry pumping. Impeller vane inlet Pump casing nose Figure 4.3-2 Operating outside BEP - At low load 3.
  • Page 27 Slurry Pump Hydraulic efficiency is a function of hydraulic turbulence - the more turbulence, the less efficiency. In slurry pumping, a high level of efficiency is therefore important. Little hydraulic turbulence is formed at BEP and the abrasion is chiefly of a sliding nature, since the differential pressure is low when the slurry passes through the impeller and pump casing.

  • Page 29: Installation

    Ideally, the pump and its drive should be mounted on a common bedplate which is fixed to a level foundation of adequate strength. All bedplates supplied by Metso Minerals incorporate holding-down bolt holes. It is recommended that the pump is installed in such a way that maintenance and adjustments can be carried out easily.

  • Page 30: Installation Tools And Equipment

    Apart from suitable lifting equipment, a standard fitter's tool kit together with suitably-sized hexagon key wrenches and torque wrenches are normally sufficient to install the pump. See Toolkit, sub-section 10.6. Metso Minerals can supply all recommended fixtures and tools at additional cost. Installation WH15AMAAAA0EN_01A.DOC...
