The FLUX VISCOPOWER high viscosity drum pump range is designed to handle a wide range of media, from low to extremely high-viscosity fluids. These positive displacement, progressive cavity pumps are available in both vertical and horizontal designs, for installation directly in drums and IBC’s, or for connection to low-level tank, mixer or IBC outlets.
Viscopower was designed with one main consideration in mind – ease of cleaning and maintenance. Consequently, the pump has very few moving parts and can be dismantled in under 30 seconds, without the use of special tools. Therefore, the Viscopower high viscosity drum pump particularly suits sanitary applications in the cosmetics, food, and beverage industries. However, its benefits also extend to industrial applications as well.
Progressive cavity drum pumps have several benefits, when compared to other self-priming pump technologies:
* Avoid dry priming. Excessive stator wear may result.
The Viscopower high viscosity drum pump family comprises three pump configurations:
The Viscopower F 570 high viscosity drum pump is designed for easy handling and is an excellent choice for transferring slow-flowing, high-viscosity media with limited adhesive properties. With two-stage gearbox (1 : 16 ratio), F 570 is powered by Flux F 400 series compressed air, commutator or brushless motors. It is suitable for handling media with typical viscosity up to 30,000 mPas. Use F 570 only with Flux motors that have a minimum power rating of 600W, including:
This compact pump is ideal for mobile use, for handling several different fluids, or pumping from various different containers. Its modular design with quick release connections allows rapid disassembly, so physical cleaning can be completed in minutes. For more demanding sticky or Newtonian fluids, the single-stage gearbox version (1 : 7 ratio) is powered by high-speed asynchronous electric motors, and is suitable for pumping fluids up to 80,000 mPas.
For challenging applications, the robust Viscopower F 580 transfers highly viscous, non-flowing, or adhesive media from barrels and IBC containers. This high viscosity drum pump can handle fluids up to 100,000 mPas, making it a powerful solution for tough industrial applications, such as transferring epoxy resins from barrels and IBC containers. The F 580 uses 3-phase asynchronous electric motors, spur gear motors, or compressed air motors and features a ball bearing clutch to prevent the pump from running in the wrong direction. Additionally, this model is available with a rotation sensor, offering indirect, contactless flow measurement to ensure accurate and efficient volume control.
The horizontal Viscopower TR works with IBC containers, tanks and any other vessel with a low-level outlet. Whereas models F 570 and F 580 are immersed directly in the pumped media, TR is coupled to the feed container outlet via fixed pipework, or suitably-sized flexible suction hose. TR can be used with lidded containers and tanks, or containers that are not accessible from above. TR creates high levels of suction, helping to draw viscous materials, up to 100,000 mPas, to the pump inlet. The pump can prime up to 4 m in height (depending on media viscosity). However, pump systems handling adhesive media should be given special consideration, to ensure the pump can prime quickly enough. The compact design of Viscopower TR is perfect for use in confined spaces, for instance, underneath tanks and mixing vessels.
Viscopower progressive cavity pumps are perfect for handling various liquid types, offering both power and smooth, consistent delivery:

Viscopower high viscosity drum pumps are available in specialised FOOD versions, ensuring compliance with stringent hygienic regulations. With ultimate cleanability, highly polished surfaces and elimination of dead spaces where bacteria could survive, these pumps are ideal for handling products such as:
Whether for industrial, pharmaceutical, food or cosmetics applications, these pumps provide ultimate flexibility, with interchangeable motors, stator options and discharge port connections.
The Viscopower high viscosity electric drum pump has been designed with a focus on ease of use, particularly efficient disassembly and quick decontamination. The design ensures that surfaces in contact with the media are easily accessible, allowing for fast, hassle-free cleaning.
Designed with flexibility in mind, the Viscopower pump is adaptable to changing performance requirements. Thanks to its modular construction and standardised interfaces, rotors, stators, motors and seals can be easily replaced or upgraded. This means one pump can deliver a range a flow rates, ensuring the pump remains effective if your pumping needs evolve over time.
*Pumping abrasive products will shorten stator life. Consider the concentration and size of solid particles entrained in the liquid. Flux Progressive cavity pumps are generally not considered suitable for handling abrasive fluids containing high concentrations of Titanium Dioxide or media with solids content >20%.

To ensure optimal performance in every possible application, the Viscopower progressive cavity barrel pump is available with a selection of stator materials. Stator choice will depend on specific project requirements, such as liquid chemistry, media abrasiveness and regulatory approvals that may be required. Furthermore, stator material and geometry influences performance, abrasive handling capability and compatibility with different fluids, under various conditions. Stator options are as follows:
(Acrylonitrile Butadiene Rubber): Suitable for maximum liquid temperature 90°C, this material is perfect for handling oils and fats, therefore, making it an excellent choice for food applications. This material is compliant with FDA / EC 1935 food safety standards. NBR stators are also suitable for handling certain abrasive products, however, please consult your Flux sales engineer for assistance with your specific application.
(Fluororubber, trade name Viton): Suitable for handling many common chemicals at temperatures up to 100°C. Unsuitable for food applications.
(Polytetrafluoroethylene): Harder and potentially faster wearing than both FKM and NBR stators, but recognised for its exceptional chemical resistance and maximum liquid temperature up to 120°C. With FDA / EC 1935 food approvals, PTFE is the best all round choice for food, pharmaceutical, chemical and cosmetic products.
Viscopower is fitted with FKM o-rings as standard. However, you can request optional EPDM, NBR and FFKM o-rings for ultimate chemical compatibility. Please consult chemical resistance charts to ensure material compatibility before purchase.
The Viscopower progressive cavity pump is available with four rotor geometries to meet differing performance requirements. All rotors are compatible with the same 53 mm diameter pump tube. These options cover project specific delivery pressure, flow rate and dosing requirements:

The Viscopower progressive cavity pump operates on the principle of rotating positive displacement. This is a highly effective method for moving liquids of varying viscosities, but is particularly well suited to handling high viscosity media.
The pump is driven by compressed air or electrically powered motor, coupled to a rotating shaft with eccentric screw at the pump inlet (similar to an Archimedes screw). Firstly, as the shaft rotates, the screw oscillates inside a stationary stator. Furthermore, the helical design of the eccentric screw and matching stator profile create delivery spaces that open and close in series, to transport the liquid from the pump inlet to the outlet. Progressive cavity pumps are considered slow running, with typical rotor speeds between 300-1000 RPM.
The pump works purely through contact between the surfaces of the rotor and stator. The resulting friction creates a vacuum which helps draw fluid into the pump inlet. The liquid enters the pump chamber, where it is pushed upwards through the rotor-stator cavities and into the pump body. The pumping action can be thought of parcelling or shovelling a fixed volume of liquid with each rotation. Therefore, the product is not energised or agitated during pumping, with the result that progressive cavity pumps are ideal for handling shear-sensitive media.
The rotor is manufactured from solid stainless steel 316, which is harder than the stator material. Thus, the stator will naturally wear over time and will require periodic replacement to maintain pumping efficiency. One of the key benefits of this design is that the viscosity or consistency of the fluid does not dramatically affect the flow rate. The amount of fluid pumped is determined by the motor speed, making it easy to control the flow rate with precision, especially when using a frequency converter. Therefore, this provides excellent flexibility for applications requiring consistent or adjustable output rates.
In addition, higher viscosity materials, especially those of an adhesive nature, take longer to flow into the pump inlet and fill the first cavity. Therefore reducing motor speed can be especially helpful, allowing more time for the material to flow into the pump and resulting in increased flow rate.
Another key feature of progressive cavity pumps is the limited number of moving parts and the associated ease of maintenance. Time required for service and repair is considerably less than other positive displacement pumps, such air-operated diaphragm pumps, or piston pumps.
For highly viscous, adhesive fluids such as epoxy resin, vertical progressive cavity pumps are an ideal solution. These pumps are designed from the outset to handle high-viscosity, sticky, shear-sensitive, or solids-laden fluids. Because the pump inlet is immersed in the fluid, with the inlet at the lowest point in the container, gravity helps the fluid flow into the pump. In addition, the pump creates considerable suction, drawing the product into the pumping chamber.
Using both gravity and suction is ideal when pumping adhesive, sticky media, especially compared to self-priming, surface mounted pumps, which rely mainly on suction to draw product to the pump inlet. Adhesive media such as honey or epoxy resin will cling to the walls of suction pipe and create so much friction, it can be impossible for the pump to prime (ie. fill the pump inlet chamber with liquid).
For especially thick, sticky products, we would recommend either the F 570 Viscopower with single-stage gearbox, or the direct-drive, high-torque F 580 model with powerful 3-phase electric or compressed air motors. Variable speed motors can be especially useful, as running the pump slowly will allow more time for thick liquids to flow into the pumping chamber. Therefore, this reduces the possibility of NPSH problems and cavitation occurring.
