Product information "Double diaphragm pump DMP model 1/2" mini plastic"

Material: Polyvinylidene fluoride carbon fiber reinforced (PVDF)
Diaphragm / valve balls / seals material: TPV (EPDM-PP) + TFM (PTFE) / PTFE / PTFE
Center block material: Polypropylene carbon fiber reinforced (PP)

Material explanation: EPDM = ethylene propylene diene rubber, FPM = Fluorine rubber, 
NBR = acrylonitrile butadiene rubber, PP = polypropylene, PTFE = polytetrafluoroethylene, 
TPC-ET + TFM (PTFE) = Thermoplastic polyester elastomer + Modified polytetrafluoroethylene, 
TPV (EPDM-PP) = EPDM/PP compound


The double diaphragm pump is suitable for industrial applications as well as for drum, IBC and tank emptying.

  • typical applications: 200 l drums, paint circulation and feeding, feeding of chemicals, solvents, acids and liquid soap
  • integrated silencer up to model size DMP 1"
  • highly resistant TFM (PTFE) membranes (modified PTFE)

Features & benefits

  • high hydraulic performance
  • maintenance optimized design and easy installation
  • self-priming (even in dry condition)
  • reinforced elastomers and thermoplastic diaphragm
  • absolutely oil-free
  • blockage-free operation

* The maximum flow rate is a value determined by means of a test bench and measured with water at a medium temperature of approx. 20 °C. The measurement is carried out at the pressure joint of the pump, without hose, nozzle or flow meter. The achievable flow rate in use is lower and depends on the individual application, the liquid properties and the configuration of the pump. The max. delivery head also depends on the pump design, motor and fluid. The viscosity values are determined with oil.

** Test assembly: Medium water / diesel, flow in preferred direction, settling section 0.2 m upstream and downstream of flow meter
