SELF-PRIMING CENTRIFUGAL PUMPS MAG-DRIVEN MADE OF PP • E-CTFE ATEX ITALY

SELF-PRIMING PUMPS This peripheral pump is a product between the displacement and the centrifugal pump, in which the medium is pumped in a peripheral channel. It can operate with inlet and outlet reversible by reversing the direction of motor rotation and are adequate to suck up chemical liquids with high specific gravity and/or high vapour tension. PERFORMANCE Strong magnetic coupling made up of rare-earth ELK pump made of ECTFE+carbon materials (Neodimium Iron Boron) and “N” (standard), “P” (powered) or “S” (strong-powered) versions allow to pump, also at maximum flow, liquids with 1.05 -...

MOTORS SPECIFICATIONS Note: Maximum inlet pressure: 1,5 bar (*) Compliant to ATEX 94/9/EC regulations RHINO and ELK pumps, with specific execution GX (E-CTFE added with conductive carbon fibres and motor E-exd), are approved to operate in explosive atmospheres, classified as per ATEX directive, Cat. 2 Zone 1 (Series II 2GD IIB at 135 °C). Inside of pump should be placed safety device.

WORKING PRINCIPLE Stopping phase: a small quantity of liquid is trapped into the pump to enable the next starting. Priming phase: the impeller gives a specific circulation of air-liquid mixture moving air from the suction pipe to the discharge side in the atmosphere. Pumping phase: after the air is totally removed from the suction side, the pipe is flooded by the liquid and the pumping phase can start. APPLICATIONS ELK pumps are ideal for applications requiring a reversible flow and service operations, used in the following sectors: • Chemical industry (acids, cleaning solutions, inks,...)...
