A Superior Solution

So why is the Murray Engineering Helical Rotor Pump superior to competitors? We choose to use the world-renowned German brand Netzsch Helical Rotor Pump as the basis for our MEPS Helical Rotor Units. Its superior design and build quality are just the beginning of the story.

The pump has a fluid mixing chamber with agitation vanes ahead of the stator inlet. These keep solids in suspension so that they enter the stator evenly. The mechanical seal also benefits from this as particulates will not accumulate in the sealing area which helps avoid premature wear and lack of lubrication on the seal.

The overall result is greatly improved wear.

Increased lifespan

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 and the lowest cost per litre pumped in the market.

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:

UNIQUE FEATURES:

UNIQUE FEATURES:

  • A larger cavity between the rotor and stator leads to a longer sealing line between these two components resulting in increased longevity
  • The ratio between the pitch's length and height 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 energy efficiency losses. This results in lower power consumption per litre pumped and represents a significant electrical cost saving over the life of the pump
  • 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 drivetrain cardan joint transmits more torque and thrust loads than a flexible shaft
