Product information "Double diaphragm pump AODD model 1 1/2” non-metallic"

Material: Polypropylene glass fibre reinforced (PP)
Material of diaphragm / check balls / seals: TPC-ET + TFM (PTFE) / PTFE / PTFE
Centre block material: Aluminium

Description of material: 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 large scale industry and plant feeding as well as for large flow rates and higher viscosities.

  • typical applications: Filter press, tank cleaning system, pigment dyes and resins
  • integrated muffler up to model size AODD 1"
  • highly resistant TFM (PTFE) diaphragms (modified PTFE)

Features & Benefits

  • high hydraulic performance
  • maintenance-optimised design and simple installation
  • self-priming (even when dry)
  • reinforced elastomers and thermoplastic diaphragms
  • absolutely oil-free
  • non-stalling 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
