This not only ensures reliable performance over many years, but also significantly reduces the total cost of ownership.
X
Advanced surface treatment
As an option, the pump housing can be supplied with a special surface treatment. This treatment offers wear reduction and improved sliding properties with low-viscosity liquids.
X
Optimum cooling and lubrication
The application-specific dimensioning of the balancing cylinder ensures good cooling and lubrication of the sealing surfaces of the mechanical seal.
X
Ventilation of the sealing chamber
The sealing chamber has its own vent hole. This enables simple, professional venting during commissioning.
X
Self-venting
The venting between the pressure and suction side starts directly at the mechanical seal. This ensures that air cushions are displaced into the vent line by the medium, even when installed vertically.

G series
KRAL 'sscrew pumps for power plants provide a resilient solution for pumping lubricants, oil feed pumps and supply pumps in continuous industrial operation. Our G series is available in six sizes and therefore covers a wide performance spectrum for power plants. The low-maintenance operation is a significant advantage for applications in fuel supply and in continuously operating circulation systems.
These power station pumps operate reliably at viscosities of up to 500 mm²/s and temperature ranges from -10 to 120 °C, optionally even up to 300 °C. This makes them suitable for use alongside lubricating oils. This makes them suitable not only for lubricating oils but also as screw pumps for bitumen or circulation pumps for heavy oil and as circulation pumps for media with high viscosity in thermal process plants. Our engineering takes installation space, operating profile and medium into account; 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 adaptable for circulation units, transfer pumps and ring main pumps. Our employees check the design for circulation pumps for closed liquid circuits, while ATEX approval and API 676 conformity support international projects with high safety and standard conformity requirements.
