Murray Engineering’s dewatering dewatering pumps and equipment are designed to withstand the harsh mining environment. Designed by highly experienced industry professionals, Murray Engineering’s dewatering pumps and equipment outstrip competitors in terms of performance, maintenance and longevity. With pumping specialists based in Pinjarra, Kalgoorlie, and Newcastle, our team has Australia-wide coverage for all your pumping requirements throughout the mining industry and beyond.
Murray Engineering Pump Sets (MEPS):
Helical Rotor Pumps
The MEPS- Helical Rotor Pump is designed for heavy-duty dewatering applications. The base unit includes a tank, progressing cavity pump, inspection ladder, valves, and piping all mounted on a common galvanized or painted steel skid. Murray Engineering also provides the unit with a control panel as required; with an integrated instrumentation panel that provides automatic operation of the pump system.
Why is the Murray Engineering Helical Rotor Pump superior to competitors?
Due to the housing design in the Helical Rotor Pump, the position of the mechanical seal/stuffing box is close to the housing flange, which allows the pumped fluid to flush and agitate the solids in the sealing area. Solids particles will not accumulate in the sealing area which will avoid premature wear and lack of lubrication on the seal.
The bearing housing of the Helical Rotor Pump has bearings greased and sealed for life, therefore requiring less maintenance. The sealing line of the rotor and stator is also longer than competing pumps, which results in increased longevity.
Don’t Settle For Inferior:
In comparison to competitors, the volume of the cavity in the Helical Rotor Pump is bigger (7% bigger than other brands). This allows the Helical Rotor Pump to run slower with the same flow and less particle build up, which significantly increases the run life of the rotor and stator on the Helical Rotor Pump compared to competitors.
The main feature of these Netzsch pumps is that they run slower than competitor brands. This is achieved by the below:
A larger cavity between the rotor and stator and leads to a longer sealing line between the two items, resulting in increased longevity.
The ratio between the length of the pitch and the height of the pitch has been designed and engineered to deliver optimal performance.
The supporting and drive structure (the coupling rod and joints) of the rotor and stator assembly have been designed to transmit the required torques from the pump drive (motor) through to the rotor with minimal losses.
Netzsch uses individual drivetrain designs for each model of pumps resulting in higher efficiency. Our competitors use the same drivetrain design in their 4, 6, and 8 stage pumps.
The bearing housing has been designed to handle the radial and axial forces developed in the pump at the maximum stated duties that the pump is rated to. Again each pump size has its own bearing housing.
- Conical-shaped stator entrance improves fluid pathway and decreases NPSHr.
The cardan joint absorbs more torque and thrust loads than a flexible shaft.
heavy duty centrifugal pumps
The MEPS- Heavy Duty Centrifugal Pump is designed for heavy-duty dewatering applications. The base unit includes a tank, heavy-duty centrifugal pump, inspection ladder, valves, and piping all mounted on a common galvanized or painted steel skid. Murray Engineering also provides the unit with a control panel as required; with an integrated instrumentation panel that provides automatic operation of the pump system.
