Dellmeco - Model PN10 - Plastic Air Operated Diaphragm Pumps
From Dellmeco Pumps
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.
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
The suction lift range is up to 8 meters. This will vary according to construction materials and application parameters. All data are based upon pumping water at 20°C.
Our pumps can operate under full submersion. The construction materials must be suitable for the surrounding liquid and the outlet must be positioned above the liquid level.
POSITIVE SUCTION HEAD
As a method for completely emptying holding tanks, clarifiers or similar containers. Optimum inlet pressure should be kept at 0.2-0.3 bar.
