KEY FEATURES DELLMECO
air-operated diaphragm pumps (AODD) are suitable for a wide range of applications.
They offer high wear resistance and can withstand aggressive chemicals such as acids, oils, solvents, paints, sludge and even media with solids, such as in wastewater. These pumps can also be used for pumping powders.
All pumps are self-priming and both capacity and pressure are easily adjustable.
This pump is a positive displacement pump that moves fluids through the movement of diaphragms driven by compressed air.
The liquid contact parts of the housing are available in the following material versions:
– Aluminum (code: A..-X)
– Aluminum with PTFE coating (code: B..-X)
– Cast iron (code: C..-X) – AISI 316 stainless steel (code: S..-X)
The suction height reaches up to 8 meters. This depends on the construction material used and the application parameters. All data are based on pumping water at 20 °C.
Our pumps can operate fully submerged. The materials used must be suitable for the ambient liquid, and the outlet must be above the liquid level.
This method is suitable for complete emptying of storage tanks, settling tanks or similar containers. The optimum inlet pressure is between 0.2 and 0.3 bar.
RECOMMENDED INSTALLATION GUIDELINES
To reduce stresses on piping and pump connections, we recommend using flexible couplings on both the suction and discharge lines and the air connection. For optimum performance, DELLMECO recommends installing a pulsation damper on the discharge side of the pump.
TECHNICAL DATA
DIMENSIONS OF METAL PUMPS
CAPACITY OF METAL PUMPS
The viscosity of the medium affects the pumping capacity.
The capacities listed in the pump characteristics are based on water (1 cPs).
When pumping higher viscosity media, the volume must be reduced accordingly.
1. Enter the desired flow rate (l/min) and boost pressure.
(example: 50 l/min and 4 bar)
2. Read the estimated energy consumption in volume and pressure.
(example: 0.40 Nm³/min at 6 bar)
