KRAL - Three screw pump (W Series)

The W series pumps from KRAL are ultra-high pressure three screw pumps specially designed for hydraulic systems operating under critical conditions. They provide extremely precise, pulsation-free delivery of oil or other lubricants at pressures of up to 120 bar. Their compact design and high reliability make the W series ideal for turbine generators, compressors, turbines and high-precision hydraulic systems.

Main characteristics:

• Ultra-high pressure: Operation at pressures up to 120 bar - for the most demanding hydraulic applications.
• High feed accuracy: Pulsation-free pumping even at peak loads.
• Compactness: Suitable for installation in nodes with limited space.
• Reliability: It is designed for continuous operation without any loss of performance.

Advantages of the W series:

• The optimal solution for hydraulic lift systems, lubrication systems, turbines and generators.
• Low noise and vibration levels - ideal for precision engineering.
• Compatible with oils, lubricants, thermal oils.

Technical characteristics:

• Productivity: up to 83 m³/h
• Pressure: up to 120 bar
• Liquid temperature: up to 180 °C (up to 300 °C with magnetic coupling)
• The viscosity of the liquid: up to 1,500 mm²/s
• Body material: cast iron / steel
