Max Flow @ Min Cost

FlowFriend is way ahead in the field of energy efficient water pumps. How is this accomplished?

• a highly efficient, new generation permanent magnet motor, high-quality German made
• an ingenious and optimized hydraulics, fully stainless steel casting
• optimum adaptation to the pond and the season by speed control
• permanent Magneet motor (PMSM)

The motor is a premium-efficiency motor IE4. It 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 a display on the pump is built, where the power, speed and hours are shown.

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

Ingenious hydraulic

The hydraulic of the pump includes a pump impeller and the pumphead.
The hydraulic system provides:

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

The FlowFriends 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.
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.

The hydraulics of the FlowFriend is fully of cast stainless steel 316. Robust, smooth and a perfect shape for minimal internal losses. Thus, the FlowFriend 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. Not 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!

FlowFriend is a dry to pump for fresh water. Specially designed for large amounts of water in the head range between 0 and 5 meters.
