    o-ring: EPDM (standard for PP pumps);
    VITON (standard for PVDF pumps).
  • Graphite Stator.
  • Rotor shaft: PVDF.
  • Max flow 1000 l/h. Max pressure up to 5 bar.
  • Temperature: PP: max 70°C – PVDF: max 90°C.

ATEX Mag drive rotary vane pumps series EM-P PP/PVDF are made of thermoplastic materials (PP/PVDF) and are suitable for corrosive liquids, alkalis, toxic, noxious and carcinogenic fluids. Thanks to the innovative mag drive system, pumps model EM-P PP/PVDF reduce the risks of leakage and the maintenance costs. EM-P PP/PVDF pumps are useful for low flow and high head applications such as Pilot Plants and Sampling.


* The head and flow of the pump refer to the performance with water at room temperature. Should liquids at high temperatures and with high viscosity and density be pumped the performance has to be calculated accordingly. The electric motor should be selected on the basis of the viscosity and the specific weight given by the customer.

Magnetic drive pumps are designed with a special sealless configuration that is suitable for handling acids, chemicals, corrosive and dangerous liquids thanks to the high chemical resistance of their construction materials and to the absence of leakage and emissions. The design is really simple and it requires very little maintenance with consequent cost savings in terms of repairing, spare parts and machine downtime (costs during the pump life).  This type of pump is not suitable for transferring liquids with solids. Liquid must necessarily be clean and free of suspended solids (max presence of solid admitted: max 2% – max 1mm).
