SELF PRIMING REVERSIBLE FLOW PUMP

The self priming , magnetic drive pumps of the TMA serie are volumetric,
can deliver the flow in both directions reversing the direction of rotation of
the motor and are adequate to speedily prime chemical liquids with high
specific gravity and/or high vapor tension. ( i.e.: H2SO4 98%, HCl 33%).

HERMETIC PUMP

Elk magnetic drive pumps are “hermetic” for the liquid pumped is totally
restrained in the pump by mean of a single static sealing O ring interposed
between of front and rear casings and no use of rotary sealing means (
like fix and sliding rings of a mechanical seal ) is made.

TOTAL RESISTANCE TO CORROSION

With GFR PP (Glass Fiber reinforced Polypropylene ) or CFF E-CTFE+C (Carbon fiber filled Etylene-ChloroTriFluoroEtylene) almost all chemical liquid can be pumped at either low or medium temperature.

EFFECTIVE PRIMING

Thanks to its design this pump develops more suction lift in shorter time compared to traditional self priming pumps.
The radial impeller, which operates perfectly in both senses of rotation, allows to invert the direction of the flow either lifting or pumping liquids like, for example, sulfuric 98%, hydrochloric 33% nitric , phosphoric, acid or sodium hypochlorite, ferric chlorite from as low as 4 m below of the suction of the pump.

HEAVY LIQUIDS

High torque coupling fitted with rare earth magnets ( Neodymium
Iron Born ) allow to pump liquids as heavy as 1,8 kg/dm3 to the max. flow of
the pump.
