hydrolub®
Grey cast iron gear pump for industrial processes
Continuously operated equipment calls for reliable components. Whether in lubrication oil applications or in processing plants, a pump is required to work reliably and longlasting. Thanks to the extensive range of components and pump sizes, hydrolub® can be configured to suit customers’ specific requirements and therefore, are far superior
to standard pumps in terms of performance.
Advantages
- High efficiencies (due to tolerances and small clearances being modified in line with applications)
- Precise displacement volume
- Self-priming
- Reliability and longevity
- Safety
- Low pulsations for oil applications (helical gears)
