1 Function and identification
1.1 Function
The Duodos is an air-driven double diaphragm pump.
The Duodos is run-dry safe and self-priming.
The pump capacity of the double diaphragm pump can be con‐
trolled by changing the pressure in the air supply. The air control is
designed for oil-free operation. The Duodos is ideally suited for the
transport of liquid chemicals.
The Duodos double diaphragm pump transports liquids up to a
delivery height of 7 m. As the pump capacity depends greatly on
the back pressure, always observe the performance curve.
Check the compatibility of the material when selecting the double
diaphragm pump. Also consider the density, viscosity, solids con‐
tent and temperature of the liquid being pumped.
Permissible values for the medium
Temperature of the medium
– PP version: 10 ... 80 °C
– PVDF version: -13 ... 93 °C
Viscosity of the medium: max. 200 mPas
Solids: < 3 mm
