Volute Casing Centrifugal Pumps of the BlockType Construction with Magnetic Coupling ALLMAG Series CMA ATEX 0 a Application For handling toxic, volatile, explosive or other fluids harmful to the environment which require the application of hermetically sealed pumps without shaft seals. The liquids must not chemically attack the materials of the pump/magnetic clutch. Abbreviation Series CMA 32 0/01 1/0 W Type of construction / Installation Horizontal volutecasing centrifugal pump, singlestage of the direct coupled design with magnetic coupling. The casing dimensions and hydraulic data correspond to DIN EN 22858 / ISO 2858. Separated by the stationary can, the transmission of the torque is contactless from the outer to the inner rotor by means of analogously arranged CoSm magnets. The outer magnetic rotor is mounted on to the motor shaft. The inner magnetic rotor is directly connected with a symmetric, doubleflow impeller thus causing the resulting axial thrust to be reduced to almost zero. Due to the between bearing mounting of the impeller, the resulting radial forces in the slidng bearings are reduced by 50%. Size Nominal discharge nozzle diameter Nominal impeller diameter HydraulicNo. Shroud diameter Maget length Material code The designation is indicated on the name plate. Materials Performance data at 50 Hz speeds Q up to 80 m 3 /h pd up to 16 bar ➀ H up to 55 m DNd from 25 to 50 t up to 150 C ➀ Inlet pressure plus internal pressure at maximum delivery head (= 0flow) must not exceed the stated pd value.

Explosion protection The pump fulfils the requirements according to EC Explosion Protection Directive 9/9EG (ATEX 0a) for equipment and equipment group II, category 2 G. Categorisation into temperature classes according to EN 13631 depends on the temperature of the pumped medium. The max. permissible temperature of the pumped medium for the respective temperature classes are shown in the below table: Hazard Temperature class Max. permissible category acc. to EN 13631 medium temperature T 3 C II 2G / c/b T3 150 C ➀ II 3G / c T2 150 C ➀ T1 150 C ➀ ➀ corresponds to the pump s temperature limit Type of protection b = Monitoring of ignition sources Type of protection c = Safe design The temperatures specified above are based on a max. ambient temperature of 0 C. Note: In case of the operation of a category 2 pump, the unacceptable heating of the pump surfaces caused by a possible operational fault must be prevented by a control mechanism. In case of an operation with know parameters (Q, H, υ, ρ = const.), a pump performance controller can be supplied with the pump to detect any operational faults.
