The company describes the ABS range as “the smartest dewatering pump in the world”.
The range comes in two series: the XJ series, which is used for drainage, and the XJS series, which is used for sludge. The range is designed for use in construction and mining applications.
“Construction sites can be difficult places to work. “Mud, slurry, stones and rocks are often found in surface water and other water can collect in areas on site. “This can cause delays in time-sensitive projects.
“Further, both surface and underground mines are harsh working environments and pose the same environmental challenges as construction sites. However, large volumes of water need to be removed to keep production running,” says Sulzer sales and marketing manager Sonja Hattingh.
These observations led Sulzer to develop the ABS XJ and XJS pumps.
Speaking at Electra Mining Africa last month, Sulzer Pumps Sweden dewatering product manager Jonas Enevold noted that the ABS dewatering pump range features electronic intelligence in the form of the AquaTronic and AquaPlug units.
“These two features save energy, reduce wear and allow for the monitoring of the pump condition without disassembly,” he says.
The AquaTronic unit ensures correct motor rotation by electronically compensating for incorrect phase order, which Sulzer says is a first among dewatering pumps.
The unit will stop the pump immediately at dry running and allow it to start again when a temperature control or level sensor detects the presence of water.
The AquaTronic unit will also shut the pump off in the event of an overload or high temperatures within the pump.
The unit can be connected to a computer through a universal serial bus connection, resulting in the display of pump performance and service diagnostic data. This allows accurate evaluation of the service and maintenance needs of the pump.
The unit also provides warnings for high and low voltage, low motor insulation or water in the pump oil.
The AquaPlug is an optional device fitted onto the pump to provide pump control and monitoring. It uses an identical plug for all pumps and is available with 16 A or 32 A sockets.
It provides an alarm for motor overheating or power failures and indicates when the pump needs to be serviced.
The plug has a selector that allows the user to choose between stopping the pump automatically or manually and starting it automatically or manually. The plug can also control the pump when needed and stop it when it is ‘snoring’ – which occurs when the water level is low enough for the pump to suck in air.
The AquaPlug works through power-line communication over a four-core power cable, on which Enevold says the company has a patent pending.
Sulzer also has a patent pending on the level sensor, which works in conjunction with the AquaPlug to provide precise water-level control; it starts and stops the pump, depending on the water level.
“The built-in pump electronics eliminate the need for traditional electrical control panels on the pumps. By stopping the pump at dry running and starting it auto- matically at a specified level, energy use is improved and wear can be reduced,” says Enevold.
The XJ and XJS pumps are available in motor ratings ranging from 2.5 kW to 8 kW and in weights varying between 39 kg and 74 kg.
“A double outer casing and good heat convection allow continuous operation at low water levels without motor damage. The ABS range of submersible dewatering pumps is made from robust materials, including cast aluminium for the outer casing, parts cast in lightweight aluminium alloy and mechanical shaft seals made from silicon carbide.
“The highly wear-resistant impeller and adjustable wear-ring are made from high chrome- alloy steel and the diffuser is made from oil-resistant nitrile rubber,” explains Enevold.
He further states that the ABS range of submersible dewatering pumps is easy to use.
