Standardized NP and close-coupled NP-B chemical pump | Munsch pumps

Description

Type NP/NP-B standardized chemical pump

The NP pump series is excellently suited to pumping tasks in the chemical industry, electroplating plants, metallurgical industries, steel and stainless steel pickling lines, evaporation and regeneration units, wet flue gas cleaning systems downstream of waste incinerators as well as in exhaust air scrubbing and industrial waste water treatment. The MUNSCH REA mechanical seal, specifically developed for non-metallic pumps, ensures maximum operating reliability and a long service life while being easy to assemble and repair. The main construction material of the mechanical seal is silicon carbide. No other material offers better corrosion and wear resistance.

Good reasons for Munsch NP or NP-B series pumps

Corrosion resistant plastic casing

Sturdy, single-piece plastic casing and solid casing cover provide diffusion-tight containment, eliminating secondary sealing problems; superior mechanical wear resistance for maximum operating reliability in chemically aggressive and abrasive environments.

Silicon carbide seal rings

Rotating and stationary seal rings are fabricated from this advanced silicon carbide, that not only offers extreme abrasion resistance but is also resistant to virtually all acids and alkalis.

Various impeller designs

Impeller available in closed and semi-open designs.

Options

Continuous flushing
Shutdown flushing
Spring chamber flushing
Volute casing drain

Industries

Reliable pumping solutions for Refineries

Pumps and Metering Systems for Distillation Plants and Applications in Refineries

Crude oil must be cleaned, separated, and converted (refined) until the final products suitable for sale are made (e.g., gas, diesel, heating oil, lubricants, propane, butane). LEWA supports you with pumps and metering systems, which are used in the refining process during chemical metering. Application with our products are distillation plants, coker, cracker, or visbreaker, for example. Ask our experts for more information!
