Often the focus on pumping systems at mines are focused around the production, mining and dewatering aspects related to the mining process. It is often forgotten that the very large associated labour force needs showers, basins, toilet facilities as well as washing machines in order to keep the mine functioning.
Mechanical Rotating Solutions (MRS) recently installed a DAB 2-NKVE MCE series pump and constant pressure booster set at a change house in Mpumalanga for a coal mine able to supply constant pressure to 55 showers, 40 toilets 30 basins and 3 industrial washing machines.
The DAB NKVE 32 MCE/P series of pumps have been designed and manufactured to meet the constant pressure requirements of modern system engineering solutions. “Being able to supply a change room of this size with pressure stability holds many advantages for our clients. “Says Franscois Steenkamp, CEO of Mechanical Rotating Solutions.
DAB 2-NKVE MCE centrifugal electric pumps
“One of the biggest problems supplying water under pressure to such a large area is “water hammering” whereby the flowrate of fluid in the pipe changes drastically. It can cause very high pressures in pipes, very high forces on pipe supports, and even sudden reversals of flow leading to burst pipes, damaged supports and leakage at joints. Not only does the DAB system address this issue but also incorporates excellent energy savings (up to 60 %), less maintenance, reduced pump wear and a substantial saving in water usage. The NKVE series of vertical multistage centrifugal pumps are suitable for medium to large user water systems that can be used for hot water and cooling water circulation, firefighting and washing systems, drinking water supply and filling of pressure vessels, sprinkler and watering systems and water purification systems.”
Excellent product support from DAB Pumps South Africa means that a variety of sets such as the sets with MCE/P inverters are readily available built in the standard version with two, three, or four centrifugal electric pumps, completely assembled on a galvanised steel base, tested and ready for installation. Complete with isolator and check valves for each pump, suction and delivery manifolds, expansion vessels, pressure sensor, on-pump inverter, protection control unit.

For every operating cycle, it is possible to switch the restart to a different pump, therefore ensuring even use of all electric pumps. It is possible to set operation times for each individual pump, switching to another pump after such set times. The “SP” pressure can be adjusted by the user using the “+” and “-” keys found on the MCE/P (as a rule, all the pumps are set to the same pressure.)
