Advantages of our power station pumps.
- Maximum efficiency.
Our power station pumps are designed for maximum efficiency to minimize energy consumption and reduce operating costs. Through precise construction and high-quality materials, they achieve a high level of efficiency that contributes to optimum performance. This not only leads to cost savings, but also to a reduction in the CO2 footprint.
- Reliability and durability.
KRAL screw pumps are known for their exceptional reliability and long service life. Thanks to their robust design and high-quality components, they are able to operate consistently even under the most demanding conditions. This means less downtime and maintenance costs, which significantly reduces the total cost of ownership.
- Ease of maintenance.
Our pumps are designed so that maintenance work can be carried out quickly and easily. Thanks to the modular design, individual components can be easily replaced, which shortens maintenance times. This ensures greater system availability and minimizes downtimes.
- Adaptability.
KRAL power station pumps can be adapted to the specific requirements of any power station. We offer customized solutions that meet the individual needs and operating conditions of our customers. This flexibility ensures that our pumps can be optimally integrated into existing systems.
- Quiet and low-vibration.
Our screw pumps are characterized by their quiet and low-vibration operation. This not only contributes to a more pleasant working environment, but also protects the surrounding components and systems from premature wear. The low noise and vibration development is a further advantage that contributes to the overall performance and longevity of the pumps.

Flexible connections
If the outer casing of the screw pump is made of steel, almost any position, direction, size, type and classification of the flange is possible. It can be optimally adapted to any installation situation.
X
Housing variants
Depending on the operating requirements, the CG series screw pumps are available with cast iron or steel housings.
X
External overflow valve
The overflow valve ensures that the liquid is diverted in the event of overpressure.
X
Rotary shaft seal
The CK series screw pump is only available with a radial shaft seal. The CL series screw pump can be equipped with different shaft seals thanks to the longer spindle set. External ball bearings are also possible. This pump line is used as a horizontal or vertical foot pump or flange pump as well as a vertical container pump.
X
Seal housing
Depending on the operating requirements, different shaft seals are possible for the CL series. The CL screw pump is the slide-in pump used in the CG series. The different housing options allow enormous flexibility in terms of fluid connections. An optional external overflow valve can be fitted to CG screw pumps.

G series
The KRAL G series is an industrial-grade solution for pumping lubricants. The pumps are available in six sizes and therefore cover a wide performance spectrum. The low-maintenance operation is a significant advantage for continuous use.
The pumps work reliably at viscosities of up to 500 mm²/s and temperature ranges from -10 to 120 °C, optionally even up to 300 °C. The compact design allows use in space-critical applications. All housing parts can be mounted in 90° steps.
Numerous options - from cartridge seals to tank installation variants - make the series extremely adaptable. The ATEX and API 676 approvals also enable use in international projects with high safety and standard compliance requirements.
