KRAL lubricating oil pumps are characterized by their ability to continuously pump large quantities of lubricating oils of different quality and viscosity, even under conditions of high differential pressure. In addition, these pumps offer further advantages over other pump types thanks to their compact design and high flexibility.

Reliable performance under all conditions.
Thanks to innovative technologies, our pumps achieve optimum pumping performance with minimum energy consumption. This contributes to a significant reduction in operating costs and increases the overall efficiency of your systems.

Durability and low maintenance.
Thanks to the use of high-quality materials and advanced manufacturing techniques, our pumps guarantee a long service life and minimize maintenance requirements. This results in lower operating costs and less downtime.

High efficiency and energy savings
The design of our lube oil pumps ensures lower energy consumption, which is not only good for the environment, but also significantly reduces your energy costs.

Low-noise operation
Our lubricating oil pumps are designed to reduce noise to a minimum. This not only improves comfort in the workplace, but also complies with the strict noise protection regulations in many industries.

Environmentally friendly
The efficiency and precision of our pump technology helps to minimize lubricant consumption and prevent leaks. This not only protects the environment, but also ensures a cleaner and safer working environment.

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.

X

Longer spindle set

Thanks to the longer spindle set, external ball bearings are also available as an option.
