Feed pumps for transporting liquids and gas

A feed pump transports liquids or gases from one place to another. We are a manufacturer, supplier and provider of feed pumps for various applications. In industry, construction or agriculture, pumps are indispensable for pumping water, oil or other media.

A feed pump works by building up pressure and setting the medium in motion in a targeted manner. It can transfer liquids into tanks, fill pipes or constantly supply systems with the required medium. Our pumps for pumping liquids are designed to be efficient, durable and reliable.

Whether you need a compact feed pump or a powerful model for industrial applications, we have the right solution for you. With our feed pumps, you can ensure that your processes run smoothly and that you remain in control at all times. The feed pumps we manufacture impress with their ease of use and high quality.

Our feed pumps are versatile and have been specially developed to transport liquids and gases efficiently. As a global supplier of pumps for pumping water, oil, chemicals and other media, we offer high-quality feed pumps for a wide range of applications. Our feed pumps impress in industry, agriculture and the construction sector with their performance and reliability.

Our pumps for pumping liquids are designed to work consistently and safely even under demanding conditions. They can transport large quantities of media in a short time, maintain a stable pressure and even handle challenging substances such as chemicals or abrasive materials.

With our feed pumps, you are opting for efficiency, durability and simple operation. Our pumps meet your requirements. As an experienced supplier, we ensure that your processes run smoothly and that you can concentrate on your tasks. You can rely on the quality and versatility of our feed pumps.

Which solution do you choose if feed pumps are to deliver with low pulsation during operation? As a manufacturer, we recommend the screw pump. It works as a positive displacement pump and hardly generates any pressure surges. The flow rate remains stable, especially when used as a circulation pump.

The system runs quietly at high pressures of up to 80 bar.
Such feed pumps protect the medium through gentle transportation. They are suitable for tank farms as feed pumps for loading and unloading. A booster pump is useful in pressure boosting lines and for Ex applications, manufacturer's instructions in accordance with IEC 61508 with SIL 1 in the protection concept apply.

Feed pumps as positive displacement pumps are required in operation when feed pumps convey viscous media, feed pumps meter and feed pumps remain constant. Feed pumps are particularly useful as transport pumps because feed pumps run with viscous media and feed pumps are controllable, so feed pumps remain plannable.

If distances are long, use feed pumps as feeder pumps to prime feed pumps, fill feed pumps and start feed pumps. Feed pumps are mandatory for bitumen, feed pumps are designed as bitumen feed pumps up to 10,000 cSt, feed pumps remain tight.
For circuits, use feed pumps as circulation pumps, so that feed pumps remain the same, and a type approval from Bureau Veritas can apply to feed pumps, feed pumps are approved as feed pumps.

The viscosity influences how feed pumps prime, seal, feed and stop feed pumps. If the medium becomes thin, they need gaps, otherwise the feed pumps slip and lose pressure. If the viscosity increases, the feed pumps draw current, they need torque, which is why feed pumps fit as screw pumps because they push and start volumes.

For oil circuits, choose feed pumps as supply pumps so that they supply, cool and save bearings. In addition, feed pumps are documented as transfer pumps in the ABS audit in accordance with the ISO 9000 standard, so they remain testable. In this way, the feed pumps maintain volume, pressure and quietness, run quietly and remain leak-proof.

Whether feed pumps meet ATEX requirements during operation depends on whether they ignite in the Ex area in vapor or mist. Feed pumps must be approved for this. At KRAL, feed pumps are available as screw pumps and run as positive displacement pumps.

The zone and temperature class according to Directive 2014 34 EU is important for feed pumps. To ensure they remain safe, feed pumps must be earthed and dissipate heat. Feed pumps with group II category 2 and II 2 GD are often suitable.

As a circulation pump, feed pumps keep oil circuits quiet. They also deliver constantly, so that they remain stable during start-up and load changes.
