FLEXIBLE ALL-ROUND TALENT Thick-walled volute casing The pump casing must accommodate pump pressures of up to 16 bar. The one-piece, thick-walled and self-supporting volute design together with the positive-fit metal casing armour offer maximum stability and reserves for high pressures and temperatures of up to 180 °C. The tick-walled volute also means added safety when pumping products with strong diffusive tendencies (e.g. chlorine) and when the pump operates under temporary vacuum conditions. The centre-to-centre dimension h 1 can be adjusted via the stainless steel brackets. The CS Series...

Energy-saving and gentle to pump materials Impellers with high efficiencies and low NPSH requirements help safe energy and minimise pump wear, even in challenging service environments. THE IMPELLER – OPTIMIZED FOR YOUR PUMPING NEEDS N umerically optimized hydraulics Solids-laden fluids The fluid dynamics of MUNSCH pumps are calculated, A solids deflector in the pump casing redirect solids away visualized and optimized using the latest numerical from the mechanical seal and back to the flow path of the techniques (Computational Fluid Dynamics). The result is process fluid. a hydraulic design with...

DOUBLE MECHANICAL SEAL – THE SAFE SOLUTION The pump is equipped with the latest generation of mechanical seals. Double mechanical seals consist of two tandem-mounted single mechanical seals. They are supplied with buffer/barrier fluid from an external source via two connections in the seal casing. One mechanical seal size fits all pump sizes Many interchangeable components Ease of mounting without the need for adjustment or alignment Ease of conversion from a single to a double mechanical seal Optimum circulation of the buffer/ barrier fluid Sense-of-rotation independent The double mechanical...
