The Flowfriend Pump gives you Max Flow with the minimum cost.

The Flowfriend Pump is way ahead of time in the field of energy efficient water pumps.

The Flowfriend motor is a premium-efficiency motor IE4. The Flowfriend Pump meets the latest energy requirements from 2015 what will be required in the industry.

The engine is fully developed and manufactured in Germany. The flow is adjustable by speed (800-2550 rpm). For controlling the pump a display on the unit is built, where the power, speed and hours are shown and can be adjusted.

The Flowfriend pump is a highly efficient, new generation permanent magnet motor, its made from the highest quality components available in German.

An ingenious and optimised hydraulics, fully stainless steel casting.

Optimum adaptation to the pond and the season by speed control
Permanent Magneet motor (PMSM)

Flowfriend Pumps

The main advantage of permanent magnet motors compared to a frequency controlled a-synchronous motors is the remarkably high efficiency at low rpm. However, even in the higher rpm range, they are significantly more economical.

FlowFriend PumpsIngenious hydraulic

The hydraulic's of the pump includes a pump impeller and the pump head. The hydraulic system provides:

  • a significant extent the overall efficiency of the pump.
  • For which application the pump is suitable

The Flow friends pump hydraulics is specially designed for high flow at low pressure. Its optimal application is between 0 and 5 meters head:

More pressure available then a propeller pump, which in some pressure piping is unsuitable.

2400 rpm: 39m3/hour @ 4 meter @ 605 Watt
2400 rpm: 23m3/hour @ 5 meter @ 610 Watt
2500 rpm: 35m3/hour @ 5 meter @ 730 Watt

Much more pressure than comparable pumps with maximum m3. Almost all pumps available with larger capacities (watts), have more than 10 meters head. This is very much at the expense of the available flow (number m3). This pressure is a good pond completely unnecessary.

FlowFriend PumpsSuitable for:

  • Drum Filters
  • Bakki Showers
  • SuperBead Filters
  • Multichamber Systems
  • Endless Belt Filter
  • Waterfalls
  • Moving Bed Filters
  • Tricklefilters

The hydraulics of the Flow friend is fully of cast stainless steel 316. Robust, smooth and a perfect shape for minimal internal losses. Thus, the Flow friend has 3 "(90mm) inlet and outlet. The allowable size of particles is less than 15 mm.

The result:

The result of the pump is best displayed in the charts pump. The pump was tested at a test facility that meets the following standards: BS EN ISO 9906.

The test bench and the prototype was shown during the Interkoi April this year in Germany. The flow test bench and production Flowfriends will to be showed during the Koishow in Arcen.

FlowFriend PumpsNot only is the flow / pressure characteristic shown, but also a so-called Power Curve.

Here you can at any point of the graph also also the exact energy of the pump will consume!

Flow friend Pump is a dry to pump for fresh water.

Specially designed for large amounts of water in the head range between 0 and 5 meters.
