Overview
FLUX drive motors are part of a modular system: Depending on the application, various pumps from the 300, 400, and VISCOPOWER series can be combined with different motors. A pump’s flow rate depends, among other factors, on the power output of the selected motor.
Five motor types cover the entire range of requirements—from portable low-volume pumping to explosion-protected continuous operation.
For driving the FLUX pump a wide range of electrical to pneumatic motors is available. Even if you work in hazardous areas or with flammable liquids. Depending on the application, different pumps can be driven by different motors. Thus, the output of a drum pump depends, among other things, on the power of the motor. Here you will find the most economical and safest drive solution for your application.

Function and Design of FLUX Motors
Every FLUX drum and container pump or eccentric screw pump requires a separate drive motor, which is connected to the pump shaft via a coupling. The choice of motor determines the pump’s speed, flow rate, and application range.
Five motor types are available
- Commutator motors offer the greatest flexibility in terms of voltage and power.
- Brushless motors operate without wear and are also suitable for hazardous areas.
- Three-phase motors deliver constant speeds for continuous industrial operation.
- Pneumatic motors require no electrical connection and are inherently explosion-proof.
- Battery-powered motors enable cordless, portable use.
Thanks to the modular design, the most cost-effective and safest drive solution can be configured for every application.

FAQ
Does altitude affect the performance of pumps and motors (e.g., at altitudes of 2,000–4,000 m)?
Yes. At altitudes of 2,000 meters or higher, pump performance decreases measurably. At 3,000 meters, the loss in performance is approximately 15%; at 4,000 meters, it is about 25%. This is caused by lower air pressure, which reduces cooling and engine performance.
Details:
- 0–1,000 m: Performance remains constant
- 2,000 m: approx. –5% performance
- 3,000 m: approx. –15% performance
- 4,000 m: approx. –25% performance
For operation at high altitudes, we therefore recommend a motor with correspondingly higher power.
Solutions for altitudes >2000 m:
- F 457 motor (800 watts)—commutator motor with high power reserve.
- VISCOPOWER eccentric screw pumps with three-phase motor (up to 1,100 watts)—for high-viscosity fluids at higher altitudes.
Is a ground cable required when operating a FLUX Ex motor with a plastic pump for non-flammable liquids?
No. Since there is no conductive connection to the pump, a ground wire is not required when using an FLUX Ex motor with a plastic pump for non-flammable liquids.
Why are FLUX Ex motors shipped with standard connectors as standard equipment rather than with Ex connectors?
FLUX Ex motors are shipped with a standard plug as standard, since the outlet is typically located outside the Ex area (ATEX zone). Ex plugs and matching Ex outlets are available upon request.
Details:
- The operator is responsible for defining the Ex area (ATEX).
- Standard equipment: 5 m power cord with standard plug, not explosion-proof.
- Optional: Ex-rated plugs and Ex-rated receptacles are available; many operators use their own systems.
- Cable configurations depending on the motor’s protection class:
-- Protection Class I (metal housing): 3-wire, 3 × 1.5 mm² with protective conductor. -- Protection Class II (plastic housing): 2-wire with protective insulation. --- Protection Class III (low voltage ≤ 42 V): max. 5 m cable length (2 × 4 mm²) due to line losses.
- Safety: There is an information label on the cable. The plug must not be plugged into an Ex zone.
