Product information "Double diaphragm pump DMP model 1/4" plastic"

Material: polyvinylidene fluoride carbon fiber reinforced (PVDF)
diaphragm / valve balls / seals material: FPM / FPM / FPM
Center block material: Polypropylene carbon fiber reinforced (PP)

Material declaration: 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


Description:

The double diaphragm pump is suitable for pumping small quantities, in laboratory applications and occasional filling operations

  • typical applications: chemical circulation and feeding, liquids with solid particles such as paints and varnishes, electroplating liquids, etc.
  • integrated silencer up to model size DMP 1"
  • highly resistant TFM (PTFE) diaphragms (modified PTFE)

Features & advantages

  • 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
