• Includes 3" / 80mm PVC fittings                                                                                                                                                                                               

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 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 FlowFriend’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 FlowFriend Standard
The standard FlowFriend 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 FlowFriend 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%.

Dry-running or submersible pumps
The FlowFriend is a dry-running pump with a sealed shaft. This technology is superior from an energy and safety perspective to submersible pumps (in which the pump’s shaft rotates in water). This is why almost all pumps used for industrial applications are pumps with a sealed shaft. As with dry running pumps, the shaft and the stator are positioned extremely close to each other, they have significantly lower energy loss in operation by comparison with submersible pumps. Submersible pumps always require a compromise. If the distance between the stator and the shaft is very small, there is a high risk of damage due to dirt that is stuck between the shaft and the stator. However, as this distance increases, the pump’s energy losses increase quadratically.
If the stator in a submersible pump becomes damaged, direct contact between the core (with voltages exceeding 300V) and the water is possible. This is why a submersible pump is not recommended for applications in which people touch the water or swim in it.

Industrial Applications

• Cooling Water / Heating HVAC: Water is used extensively in industries for cooling and heating purposes. In HVAC systems, water circulates through heat exchangers to maintain optimal temperatures. Cooling towers often rely on water circulation to dissipate heat.
• Water Supply: Industrial facilities rely on a steady supply of water for their operations, including process cooling, cleaning, and manufacturing.
• Pressure Increase: Water circulation systems are often used to increase pressure for industrial processes, such as in pumps or pressurized systems.

Water Features

• Waterfalls, Streams, Fountains: In landscaping and decorative architecture, water circulation is used to power water features like waterfalls, streams, and fountains. These systems often rely on pumps to circulate water continuously.

Sanitary Water Use

• Sanitary Water Systems: In residential or commercial buildings, water circulation ensures that sanitary water is delivered to faucets, showers, and toilets.

Swimming Pools and swimming Ponds

• Swimming Pools: Water circulation in swimming pools helps maintain cleanliness and temperature. Filtration systems circulate the water through filters to remove debris, and pumps keep the water moving to avoid stagnation.
• Swimming Ponds: Similar to swimming pools, swimming ponds use circulation systems for water quality management. They often incorporate biological filters to maintain the ecosystem.

Aeration

• Aeration Systems: Used in various applications like wastewater treatment or aquaculture, aeration ensures the water has enough oxygen to support aquatic life and promote microbial digestion of organic waste.

Agriculture

• Water Circulation for Irrigation: In agriculture, water circulation is crucial for irrigation systems. It ensures water reaches plants evenly, whether through drip irrigation, sprinklers, or canals.

Livestock and Zoos

• Water Circulation for Livestock: Livestock require fresh, clean water for hydration and health. Circulation systems help maintain water quality in troughs, tanks, and reservoirs.
• Zoos: In zoo environments, water circulation is often part of habitat design for animals that need aquatic environments, such as fish, amphibians, or aquatic mammals.

Aquaculture

• Aquaculture Filtration Systems:Bead Filter: A type of mechanical filtration used in aquaculture to remove suspended solids.Trickle Filter: A biological filter that provides a large surface area for beneficial bacteria to grow, converting toxic substances like ammonia into less harmful compounds.Drum Filter: A rotating filter that captures particles from the water by using a mesh drum.Multi-chamber Filter: A filtration system with multiple chambers that can handle both mechanical and biological filtration to maintain water quality.Belt Filter: Used for continuous filtration of larger quantities of water, often employed in industrial-scale aquaculture systems.

Fish Ponds

• Fishpond Circulation Systems: Maintaining water circulation in fishponds is essential to keep oxygen levels high and remove waste products. Aeration, filtration, and regular water movement are key components of pond management to ensure a healthy environment for fish.
  

Aquaponics

• Aquaponics is a sustainable agricultural method that combines aquaculture (fish farming) and hydroponics (soil-less plant cultivation) in a closed-loop system. Fish waste provides organic nutrients for plants, while plants naturally filter and purify the water, which is recirculated back to the fish tank. This system conserves water, reduces the need for chemical fertilizers, and allows for the simultaneous production of both crops and fish, making it an efficient and environmentally friendly method of food production.

These systems rely on pumps, filters, and often energy-efficient technology to ensure that water is continuously circulated, ensuring it stays clean, healthy, and properly managed for both industrial and recreational uses. Would you like to dive deeper into any of these specific applications?
