MAIN FEATURES
DELLMECO air operated diaphragm (AODD) pumps are suitable for a wide range of applications.
They have a high abrasive resistance and withstand aggressive chemicals including acids, oils, solvents, paints, sludges and even media containing solid particles such as found in waste water. These pumps can also be used for transferring powders.
All the pumps are self-priming and the capacities and pressure can be easily controlled.
This pump is a positive-displacement pump that transfers fluids by means of diaphragms movement operated by compressed air.
The casing in contact with the fluid is made of PE (polyethylene), PE conductive, PTFE (polytetrafluoroethylene), PTFE conductive.

RECOMMENDED INSTALLATION GUIDELINES
To reduce piping and pump connections stresses, we recommend flexible connections on both the inlet and outlet pipes and air inlet connections.
For best results DELLMECO recommends installing the pulsation dampener on the discharge side of the pump.

CONNECTION TYPES – PLASTIC SERIES
Standard BSP
This is a standard connection for all plastic and metal pumps.
S – split connections
All pump models can be fitted with split connections (code S).
The pump can be converted from a standard double-action air-driven diaphragm pump into a unit with two single chambers. The suction and discharge connection are replaced by a split sleeve with a separate suction and discharge for both chambers. Both chambers are independent and by having them with the same drive it means there can be two media streams in a 1:1 ratio.
Flange connections PN10
This options offers the possibility to use flange connectors according to DIN/PN 10.
The inlet/outlet flange connections are by thread bushings made of stainless steel. The attached O-rings have to be inserted into the grooves of the manifolds to improve sealing before connecting the pump.
F1 – Flange connection PN 10 EPDM
F2 – Flange connection PN 10 NBR
F3 – Flange connection PN 10 FEP/FPM
Other types of flange connections
F4 – JIS B2220
F7 – PN10 DIN 2576
F8 – ANSI 150 RF SO
F9 – PN 10/16 DIN 2277/2278
