NPC Mammut centrifugal chemical pump

The giant for corrosive and abrasive service environments

NPC Mammut centrifugal chemical pump

For pumping tasks beyond the norm: the NPC Mammut centrifugal pump is the problem solver for extreme tasks. Here, MUNSCH has combined an extremely robust design and large wall thicknesses with excellent energy efficiency and optimum suction behaviour to redefine performance.

The NPC Mammut can handle flow rates of greater than 1000 m3/h even in abrasive and corrosive service conditions. The higher the pump head, the better is the performance of this centrifugal pump.

PVDF	-20 …120 °C	Versatile, partially fluorinated plastic; depending on the application, an economical alternative to PFA.
PP	0 … 90 °C	Good resistance to many inorganic acids; offers excellent wear properties.
UHMW-PE	0 … 80 °C	Highly cross-linked resin offering excellent chemical resistance in addition to outstanding wear properties. Ideal for fluids with high levels of solids.

Tailor-made mechanical seal

Each MUNSCH shaft seal is matched to the specific application. Being the linchpin in the pump system, the mechanical seal must be right for you – and for your pumping task.

As MUNSCH pumps operate in demanding service environments, the seal as well must satisfy exacting demands. To ensure the highest standards of quality, we have developed a seal offering maximum reliability in tough service conditions while at the same time being individually configurable: the MUNSCH REA-F (S/V).

Its flexibility and adaptability notwithstanding, this metal-free seal comes with a high level of standardization: one seal size fits all the pumps of the NPC Mammut series. In this way, MUNSCH helps you simplify spare parts inventory management and creates confidence on the part of your maintenance staff. Subsequent conversion from a single to a double-acting mechanical seal or vice versa is feasible at any time with a minimum of effort. Flushing connections provided allow various flushing arrangements to be retrofitted without the need for any major modifications in the case of changed service conditions.
