Self-Contained Process Water Booster Pump System For Local Mine


The Problem

A local mine required a process water pump with the ability to maintain constant system pressure despite the fluctuations the discharge system may experience.


In order to fulfil that requirement the pump needed to:

  • Be controlled by a Variable Speed Drive (VSD);
  • Contain an accumulator to maintain constant system pressure

The pump, accumulator and all associated instrumentation had to be provided as a complete self-contained package on a single base frame.

Our Solution

All Pumps Sales & Service designed and supplied the complete system for the client requested application.

The pump system uses a Southern Cross ISO Sovereign centrifugal pump. The pump is then coupled to an IP66 motor, after which they are mounted on a galvanised steel base along with discharge pipework.


The discharge pipework includes:

  • IFM SI5006 flow switch,
  • EJA530E pressure transmitter,
  • And valves connected to the pressure accumulator.

To complete the project, the discharge pipework was also painted to the color specification provided by the client

Project Highlights - Process Water Booster Pump

The pump system was designed according to the needs of the mine. Here are some of its capabilities:

  • Control Logic: The pump system involves the accumulator to maintain pressure in the process water discharge system while no water is being used;
  • The pump does not cycle on or off excessively to account for leakages or small intermittent discharges of the process water;
  • When the pressure in the accumulator drops below a set level, the VSD starts the pump to maintain the system pressure at the pre-set level;
  • A detection system called the flow switch allows the detection of no-flows. This allows the pump to stop running if the no-flow is longer than the allocated pre-set duration.
  • After the flow switch detects no-flow for a pre-set time duration, the pump stops running;
  • This allows the accumulator to keep providing the required pressure needed for the task;
  • And the pump is designed and coloured according to client specification.
