strong, safe, self-priming – MAGSON MAS

MAGSON MAS achieves a very high suction capacity thanks to its patented, valveless process.

Whenever you have to deliver highly aggressive fluids out of tanks from above, self-priming pumps should be your first choice. Using a patented valveless technique, MAGSON MAS pumps feature an excellent priming capacity.


To prevent damage to the environment, most polluting and aggressive fluids are stored in double shell tanks. When delivering fluids out of such tanks, a non-selfpriming centrifugal pump would have to be attached at bottom level of the tank.

As the risk of leakage there is very high, this would require a lot of safety precautions. By far the safer and less expensive thing is to use a selfpriming magnetically coupled centrifugal pump. This pump also has to prime fluid, but due to its integrated priming tank takes in and delivers the fluid from the bottom up. Being suitable to run dry for a limited period of time, MAGSON MAS pumps are also able to drain a tank down to the last drop.

 

Installation of an MAS pump in comparison to a non-self-priming MA pump: 

MAGSON MAS pumps (above) prime fluid from the bottom up whereas non-self-priming MA pumps only prime horizontally.


Advantages of MAS pumps are:

  • excellent priming capacity of 5m.WG in less than 2 minutes
  • capacity range of up to 27m.WG and 470 l/min
  • no additional priming tank required
  • being suitable to run dry for some time, they can also be used for total drainage

Operating principle of MAGSON MAS pumps

Before starting the pump:

The housing with integrated priming tank has several chambers. Before starting the MAGSON MAS pump for the first time, fill it up with fluid.

Priming:

The impeller and priming chambers’ design ensures that air is evacuated and a two-phase mixture (of fluid and air) is delivered without causing any damage. There is always enough fluid in the bottom chamber to supply both the impeller and the bearing with fluid.

Delivery:

When delivering, MAGSON MAS pumps like MA pumps operate as magnetically coupled centrifugal pumps without shaft seal in an equally reliable and efficient way.

Stop

When the pump stops, the fluid in the suction line flows back into the tank. The special layout of the internal chambers makes sure that there is always enough residual fluid in the pump housing and the priming tank is not emptied totally. This patented technique does not require any valves.
