KRAL - Three screw pump (K Series)

KRAL's K-series pumps are high-performance three screw pumps specially designed for pumping clean lubricating and fuel liquids with low to medium viscosity. They provide stable operation with minimal pulsation and low noise, making them ideal for marine, power generation and industrial applications.

Main characteristics:

• Low noise level: Thanks to the three-screw design, the pump runs quietly and smoothly.
• Compact design: Ideal for installation in tight spaces.
• High efficiency: Optimised hydraulics for a stable fluid flow without pulsations.
• Reliability: Durable materials and a minimum number of wearing parts.

Advantages of the K series:

• It can work with liquids of various viscosities, including fuels, lubricants, and thermal oils.
• Suitable for continuous operation in harsh environments.
• Available with magnetic coupling for pumping hot liquids up to 300 °C.

Technical characteristics:

• Productivity: up to 467 m³/h
• Pressure: up to 16 bar
• Liquid temperature: up to 300 °C (with magnetic coupling)
• Viscosity: up to 1,500 mm²/s
• Body material: grey cast iron / steel / bronze (optional)
