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 inconspicuously yet reliably. Precisely the environment in which MAAG tried and established gear pumps develop their full potential. Thanks to the extensive range of components and materials of construction to choose from, MAAG gear pumps can be confi gured to suit customers’ specifi c requirements and are therefore far superior to standard pumps in terms of performance and reliability.
