Orange Line – Air-operated diaphragm pumps: reliable brand quality

There are many reasons to choose an Orange-Line OEM pump. The prototype for these pneumatic double diaphragm pumps was introduced in 1955. Much has changed in the pump market since then, but some things have remained the same: Orange Line air-operated diaphragm pumps are among the best-known and most reliable models on the market. They are characterized by efficient operation and reliable performance. Thanks to new developments, the pumps are constantly being adapted to the ever-changing requirements of different industries. This is why Orange-Line pumps include tried and tested models as well as those that meet the latest requirements.

The advantages of double diaphragm pumps are appreciated and used in many branches of industry. They can be used for numerous liquids and gases. Thanks to their design, they transport even corrosive or highly volatile substances reliably and safely. At the same time, they are easy to operate and require little maintenance. Air-operated diaphragm pumps are suitable for oil, paints and varnishes, gases or various chemicals, for example. This is why they are widely used in the petroleum, petrochemical and chemical industries. They have also proven themselves in the food industry and in pharmaceutical companies. They are also ideal for forwarding fresh or waste water. If you are looking for an after-market air-operated diaphragm pump for your company, Dellmeco offers a wide range of Orange Line pumps.

Discover our extensive range: The experts for double diaphragm pumps provide you with OEM pumps in the Orange Line style in various sizes. They are suitable for many common industrial applications. You also have a choice of different materials. You can opt for a suitable plastic such as polypropylene or polyvinylidene fluoride or choose a pump made of stainless steel, aluminum or cast iron. Regardless of which model you choose, all Orange-Line style pumps perform reliably and are durable thanks to their high quality. So you will find exactly the right Orange Line pump for your company!

High-pressure variants
High pressure pumps are particularly suitable for use in the following areas of application:
  • Coating of chamber filter presses
  • Coating of spray nozzles
  • Delivery of high viscosity media
  • Paint lines
  • Overcoming large pump heights
Operation Our HP range achieves a delivery pressure of 16.0 bar at a drive pressure of max. 8.0 bar through an external pressure converter (booster). With this compressed air booster, our pumps achieve a max. delivery quantity of 34 m3/h (DM50/565). All housing components which come into contact with the product are made from polyethylene (PE), aluminium, grey cast iron or stainless steel.

Dellmeco HP pumps distinguish themselves in that they have a self-regulating design and thus do not require any regulation with regard to dry running, excess pressure or speed. There are also no rotating components, of course, resulting in a particularly gentle material delivery.
Pulsation damper
When operating compressed air driven double diaphragm pumps (positive displacement pumps), a pulsating delivery flow results from the oscillating movement of the diaphragm. In order to achieve an almost uniform delivery flow, the use of a suitable active pulsation damper is mandatory.

The Dellmeco F range is a specially developed pump with integrated pulsation damper and two separate product chambers. The first product chamber is used for delivering a liquid from a reservoir to the system. This chamber works by using a directly installed and actively controlled pulsation damper. The product flow is thus delivered evenly. An air pressure of at least 1 bar is required for perfect use of the pulsation damper.

The second chamber is used for returning the excess product (e.g. colour, glue, adhesive, etc.) from the system to the reservoir. The second chamber can also be used for circulating the product in the reservoir. The quick sedimentation of a product can thereby be prevented.

When using Dellmeco pumps with plastic housing, the pulsation damper is screwed directly onto the material outlet without the use of further components. When using pumps with metallic housing, the pulsation damper is installed downstream from the pump. Each pulsation damper has a separate compressed air connection. Pumps and pulsation dampers should be connected to the compressed air supply together so that both units are supplied with the same air pressure. As soon as the pump is supplied with air pressure and begins delivery, the pulsation also begins reducing the pulsation. The diaphragm in the pulsation damper, as in the double diaphragm pumps, serves as a separating membrane between the air side and the product side. If the air pressure is reduced or increased as a result of modified operating conditions, the pressure on the delivery side is also reduced or increased. This occurs both in the pump and in the pulsation damper. Consistently good damping of the pulsation is achieved, caused by this automatic adjustment of the pressure. Use in potentially explosive areas (EX II 2GD TX) is assured through the use of conductive polyethylene as the housing material.
