Standardized pump CS and
closed-coupled pump CS-B

A new pump generation for demanding applications in the chemical industry.

With its CS and CS-B series, Munsch places a new energy-efficient generation of non-metallic centrifugal pumps onto the market. Manufactured from high-performance engineered plastics, the pumps are equipped with the latest generation of metal-free mechanical seals. The robust design of Munsch mechanical seals is a guarantee for long service lives even in high-temperature service or when pumping fluids with high solids loads. Together with the magnetically coupled pumps of the CM / CM-B series, Munsch offers you now a complete pump range for virtually all your pumping needs.


Standardized Chemical Pump CS/CS-B

Flexible all around talent

The CS Series chemical centrifugal pumps with shaft seal are the solution of choice for corrosive and abrasive service conditions and whenever it comes to pumping fluids posing a health and environmental hazard. This CS pump series has been specifically developed for applications in which the use of magnetically coupled pumps is not advisable or undesirable because of the tough service environment.

Casing dimensions, assembly dimensions and design according to SO2858 / ISO5199


Good reasons for a Munsch CS or CS-B chemical pump

Resistant contact surface

All liquid-contacted pump components are fabricated from thick-walled PP and PVDF or universally chemical- resistant PFA plastics. The ceramic components of the mechanical seal combined with the secondary static seals manufactured from fluoroplastics make the pump quasi universally resistant.

Types of construction

The CS Series standardized pumps are designed with fitting dimensions to EN 22858, ISO 2858 and ISO 5199. For the CS-B Series close-coupled pumps, this applies only to the flange connections.

High-performance shaft seals

The CS/CS-B series can be supplied with either single- acting or double-acting metal-free mechanical seals. Ceramic components and a variety of flushing options make the pumps suitable for applications involving high solids loads.

Casing with high wear reserve

Volute casing with wall thicknesses of > 10 mm

Tolerant to solids

A solids deflector effectively keeps solids away from the shaft passage.


Allowing flexibility to your application our CS pumps can be ordered with or without close-cloupling:

  • Standardized CS pump
  • Close-coupled CS-B pump 

Further options:

  • Continuous flushing
  • Shutdown flushing
  • Spring chamber flushing
  • Volute casing drain
  • Temperature sensor in volute casing

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!
