GEAR-TYPE HYDRAULIC PUMPS

Modern machines used in construction, logging, mining and material handling rely to an increasing extent on hydraulic systems.   The increased productivity of these machines requires that hydraulic pumps have large capacities and high pressure ratings to handle the heavier loads, faster cycles and higher travel speeds.
High pressures impose greater stress on all components in the hydraulic system.  At the same time, increased reliability as required for operational safety.  Careful maintenance is essential to reduce failure rate, extend service life and insure safe machine operation.
Gear-type hydraulic pumps will normally give good performance over a long period of time when operating in a properly maintained system.  Clean oil of the correct grade, regular filter changes and frequent inspections of all hydraulic system components are essential to hydraulic pump performance.
