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 the following material versions: Aluminium (code: A..-X), Aluminium coated with PTFE (code: B..-X), Cast Iron (code: C..-X), AISI 316 (code: S..-X).

Dellmeco Aluminium & AISI 316 pumps

Features & Benefits

Designed to succeed – temperatures up to + 120°C – pressure up to 14 bar – lubrication-free operation – low air consumption – abrasion resistance (PE, PE conductive)

Flexible installation – BSP as standard – PN10, PN16, ANSI, NPT, JIS, RJT, split manifold configurations available – connections may rotate 180°

Solid, compact and strong – housing machined from solid PE, PTFE as well as conductive PE and PTFE – withstands aggressive chemicals – gentle pumping action – viscous media transfer

Perfect diaphgram – completely smooth liquid-side surface (no holes) – no metal in contact with the media – materials made match the application

HOW TO INSTALL DELLMECO PUMPS?

Self-Priming Application 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.	SUBMERGED OPERATION 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 bar g As a method for completely emptying holding tanks, clarifiers or similar containers. Optimum inlet pressure should be kept at 0.2-0.3 bar.

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.

METAL TECHNICAL DATA

IMETAL PUMP DIMENSIONS

METAL PUMP CAPACITY

The viscosity of the media affects pump capacity.
The capacities specified in the pump performance charts generally refer to water (1cPs).
The volume mus be reduced accordingly when pumping media with higher viscosities.
