Product information "Double diaphragm pump DMP model 1 1/2" PEE PURE"

Material: Polyethylene (PE)
Diaphragm / valve balls / seals material: PTFE / PTFE / EPDM
Center block material:  Polypropylene glass 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 food and pharmaceutical applications, as well as large flow rates and higher viscosities.

  • typical applications: liquid food and luxury food, pharmaceutical agents and cosmetic products
  • highly resistant PE material with low coefficient of friction
  • FDA compliant

Features & Advantages

  • high hydraulic performance
  • maintenance optimized design and easy installation
  • self-priming (even in dry condition)
  • ice-free air system
  • blockage-free operation
  • food safe connections

* 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
