What makes the NPC standardized pump so special?

High efficiencies and excellent suction behaviour
High wear allowance through high-quality, thick-walled plastics
Minimum wear through perfect hydraulic design and the latest manufacturing methods
Long-lived and maintenance-friendly
Extremely robust, easy-to-service mechanical seal

High-quality construction materials

MUNSCH NPC chemical pumps are available in the following main materials: PP, PVDF and PTFE/ PFA for virtually universal fluid resistance.

PFA	-20 …180°C	Universally applicable fluoropolymer; suitable for organic and inorganic fluids
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	-30 … 90 °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 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.

Maximum flexibility

Powerful pumps must offer flexibility and at the same time operate at the optimum operating point. For best efficiency, centrifugal pumps must operate at the optimum pressure and flow rate.

Operation near the point of best efficiency not only optimizes energy consumption, but also reduces material wear and shaft load, ultimately translating into a longer service life of the pump and reduced operating costs. The bigger the pump, the more important is the efficiency.

To offer you highest flexibility at maximum possible efficiency across all pump sizes, all MUNSCH pumps will be matched to the specific-site conditions to the maximum extent possible. For this purpose, we can draw on digital simulation techniques and the latest manufacturing methods – to make sure that your tailor-made pump as well runs efficiently.
