Performance data Performance data FACTS The MUNSCH CM+ at a glance FDAconformant material grades also available PLAIN BEARING MATERIALS CM+ series standardized pump with dimensions to EN 22858/ISO 2858/ISO 5199 or CM-B closed-coupled pump with casing dimensions to EN 22858/ISO 2858 The standard construction material is silicon carbide, known for its unsurpassed resistance against corrosion and wear. Dry run-protected plain bearings are available as an option. An additional surface treatment makes these bearings tolerant to temporary dry running. IMPELLER TYPES Closed, semi-open or vortex designs...

1. VOLUTE CASING Replaceable and with thick-walled 10 mm PFA liner. For details, see Page 12 A look inside the MUNSCH CM+ is worthwhile! The inner values of this innovative magnetically coupled pump will convince any pump enthusiast. 7. SECONDARY SEALS Additional extra protection for staff and plant. Pressure-resistant up to 10 bar and absolutely tight in case of pump failure! 2. IMPELLER Robust design through single-piece impeller-shaft construction. Massive pump shaft, radially sealing O-rings and a large impeller core ensure optimal operating reliability. 3. THERMOCONTROL Fluid temperature...

In detail: Volute casing, plain bearing holder and spacer can In detail: Plain bearing and inner magnet assembly IN DETAIL: Volute casing, plain bearing holder and spacer can – the static components of a centrifugal pump VOLUTE CASING The pump casing is designed as a self-supporting volute casing with a minimum wall thickness of 10 mm throughout. Compared to an annular casing, this offers the advantage of having no welds or joint prone to leak. The thick-walled plastics preclude casing deformation, especially at high temperatures and/or under vacuum conditions. The volute casing is completely...

In detail: Impeller and inner magnet assembly Handling: QuickFit and MagPull Impeller and inner magnet assembly – the rotating components of a magnetically coupled pump ENERGY-EFFICIENT AND MATERIAL-FRIENDLY HANDLING Our MagPull and Quickfit easy-maintenance systems facilitate and accelerate pump maintenance, without having to remove the pump from your system. Impellers with high efficiencies and low NPSH requirements help save energy and minimize pump wear, even in challenging service environments. QUICKFIT IMPELLER AND INNER MAGNET ASSEMBLY Impeller core and shaft are of single-piece construction....

Safety concept 5. DRY RUN-PROOF PLAIN BEARINGS The CM+/CM-B+ series pumps can be equipped with dry run-proof plain bearings. Durable protection against dry running is, however, not guaranteed. Effective dry run protection is ensured by monitoring the suction head and flow rate. Whenever safety is top priority! 11. 6. SPACER CAN GASKET The plain bearing holder and intermediate lantern are connected by a separate bolted flange. The gasket compression can be readily checked from the outside. 7. ASSEMBLY There is no need to worry about gap dimensions during pump assembly. No precision measuring tools...

Fluids with solid-content Fluids with solid-content FLUIDS WITH SOLID-CONTENT Solids require additional measures Pumps with vortex impellers have no vanes in the flow path of the volute. The impeller induces a vortex in the suction nozzle already, thereby continuously accelerating the fluid pumped. PUMP DESIGN WITH EXTERNAL LUBRICATION SOURCE FOR PLAIN BEARING When permanently pumping fluids with solid-content, an external lubrication source will be needed for the plain bearing. Unlike the standard design, the impeller is not provided with a circulation bore in such cases. Instead, a product-compatible...
