Flow Friend Pumps

 

Flow friend pumps are now amongst the most powerful and yet most energy efficient pumps available today.

 

The motor speed (600-2,550 rpm) can be adjusted as standard with every type of FlowFriend. The pump includes a display for this purpose that also shows power consumption and hours of operation. Every FlowFriend can also be controlled externally via an optional 0-10V port. The major benefit of permanent magnet motors (DC motors) compared to frequency controlled asynchronous motors is the remarkably high effuciency at low rpm. However, even at higher rpm, these pumps are significantly more efficient.

 

Ingenious pump housings

 

A pump’s hydraulics consist of the pump’s rotor and the pump’s housing. The FlowFriend’s hydraulics are entirely made of cast 316 stainless steel. Robust, smooth and a perfect shape to keep internal flow losses to a minimum.

 

FlowFriend PRO.

 

This Axial-flow (impellor) pump has a low pump lift and large water volume. For exampe, at 0,5 MWC, a capacity of 50m3/h (11,000 gallons per hour) is acheivable at a power consumption of only 200 watts. The PRO can deal with signifcantly higher pressure than so-called 'air-lift' based systems, and the PRO is outstandingly flexible in use on account of its adjustability. Uses are mult-chamber, moving bed and drum filters. Plus the are popular in recirculation systems in fish farms.

 

Motor and seal.

 

The FlowFriend has a very high-quality Eagle Burgmann shaft seal. The motor is manufactured by one of Germany’s largest and most important producers of electrical motors. The motor’s efficiency, depending on the RPMs, is between 88 and 94%.

 

Product characteristics at a glance

 

  • extremely energy efficient - up to 94%
  • standard ow/rpm controls
  • optional 0-10V control.
  • Extremely quiet
  • A highly efficient new generation of permanent magnet (DC) motor
  • 3 different optimised pump housings, cast completely of stainless steel grade 316
  • variable flow on all models for optimal versatility
  • can be used anywhere in the world ranging from 100-240V/50-60Hz
  • Massive flow rates acheivable for very low energy consumption
