FlowFriend Junior

The FlowFriend range has now been further extended with the FlowFriend Junior. The FlowFriend Junior has much in common with the current FlowFriend models, but it also has a number of significant differences.

The most important difference in the construction of the FlowFriend Junior is that the motor and the control electronics are separated from each other. The motor complies with IP class 67 because the pump does not need a cooling fan. The electronics can be assembled in an easily accessible place and can be controlled remotely in a number of ways.

The control cabinet, pump and cable are fully EMC-shielded.

The extremely efficient design of the FlowFriend Junior has been retained. This means that hydraulic, motor and control electronics losses are all minimised.

The maximum efficiency of the hydraulics at full load is above 85%, that of the motor above 94% and for the control above 98%. The motor suffices with regard to the most recent, not yet officially released IE6 standard for energy efficiency.

The FlowFriend Junior key features:

  • Motor with IP67 protection class
  • Extremely energy-efficient
  • External controller – short-circuit resistance and IP66
  • 0-10V/0-20mA/4-24mA external control
  • Adjustable 2-40 m3/hour/20-370 Watt/500-3000 rpm
  • Without fan – extremely quiet
  • IE6: latest generation permanent magnet motor (EC/BLDC)
  • 7-metre pump head
  • Aluminium/Stainless Steel
  • Max. flow 40 m3/hr
  • Wattage – 10-375
  • Optional Bluetooth
  • Analogue inputs (0-10V/0-20mA/4-20mA)
  • Digital inputs
IP66

The hydraulics in the FlowFriend Junior Pump are, just like in the other FlowFriend pumps, made of 316 stainless steel and of the mixed-flow type. This means a pump head of up to 7 metres and a flow adjustable to 40 m3/h so the pump has a large area of application for efficient use. The FlowFriend Junior Pump is fully adjustable (500-3000 rpm) using an external control system.

FlowFriend Junior Pump control electronics are supplied with short-circuit resistant control electronics and comes standard with the below:

The power consumption can also be read off with this control unit. The Junior can be remotely controlled using the many analogue and digital inputs.

The Flowfriend Junior Pump:

  • extremely energy efficient
  • standard RPM controls
  • high flows at low energy consumption
  • extremely quiet
  • highly efficient, new generation of permanent magnet motor
  • optimised hydraulics, cast entirely from 316 stainless steel
  • optimal coordination between pond and season
  • premium efficiency IE4 motor
  • motor developed and manufactured in Germany
  • can be deployed anywhere in the world
  • voltages ranging from 100-240V/50-60 Hz

Ability to adjust the Flowfriend Junior Pump RPMs (600-2550 RPMs) is a standard feature. The Flowfriend Junior Pump includes a display for this purpose that also displays power consumption and hours of operation. The major benefit of permanent magnet motors compared to frequency controlled asynchronous motors is the remarkably high efficiency at low RPMs. However, even at higher RPMs, these FlowFriend Pro Pump are significantly more efficient producing in excess of 35 m3/hr at only 350 watts !

Flow Friend HP Pump
Flow friend HP Pump

The Flow Friend HP pump are way ahead in terms of pumping water energy efficiently. The Flow Friend HP (high Pressure) already today meets the highest MEI category of over 0.7.

The MEI – Minimum Efficiency Index category is related to the efficiency of the motor, as well as the pump’s hydraulics and a directive was developed in 2012 to mandate the energy efficiency of water pumps.

To underline this extraordinary accomplishment, the EU has mandated a minimum MEI of 0.4 as compulsory effective July 2014.

The Flow Friend HP Pump Series:

  • Extremely energy efficient
  • Standard ow/rpm controls
  • Optional 0-10V control
  • High flows at low energy consumption
  • Extremely quiet
  • Highly efficient new generation of permanent magnet motor
  • 3 different optimised pump housings, cast completely of stainless steel grade 316
  • Optimal adjustment for versatile application
  • Premium efficiency IE4 motor
  • Can be used anywhere in the world ranging from 100-240V/50-60Hz

The motor speed (600-2,550 rpm) can be adjusted as standard with every type of Flow Friend. The pump includes a display for this purpose that also shows power consumption and hours of operation. Every Flow Friend can also be controlled externally via an optional 0-10V port. The major benefit of permanent magnet motors compared to frequency controlled asynchronous motors is the remarkably high efficiency 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 Flow Friend’s hydraulics are entirely made of cast 316 stainless steel. Robust, smooth and a perfect shape to keep internal losses to a minimum.

The hydraulics:

determine the pump’s total efficiency for the large part
determine the pump’s suitability for a particular use

The Flow Friend HP Standard

The standard Flow Friend has a mixed- ow pump housing, a type that is also often used at pumping stations. Its optimal field of application is for a pump lift of between 1 and 5 metres. The hydraulics have been designed such that greater pressure is available than with an axial (propeller) pump. As a result, significantly less energy is used in comparison to pumps of similar capacity.

Almost all pumps with high capacity have more than 10 metres of pressure. This high available pressure uses a great deal of energy. If there is higher back pressure to any extent, resulting for example from longer hose lengths, numerous bends and difference in height, then this ‘standard’ FlowFriend is the optimal choice. The FlowFriend has a 3” screw thread connection at both the suction and the pressure sides.

Motor and seal

The Flow friend HP Pump has a very high-quality Eagle Burgmann shaft seal. The motor has been designed in-house and 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%.

Permanent Magnet motor (PMSM)

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.

Ingenious 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:

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