Parker PAVC series hydraulic piston pump PAVC38 PAVC65 PAVC100 PAVC100B3L4222

• Use a clean lubricant (compatible with the working fluid) on all pump components during assembly. • Thoroughly clean the reservoir, suction lines, suction strainer, drain lines, etc., before re-installing the pump. Most premature pump failures occur when contaminants from a previous failure have not been completely removed from the system, or cause for previous failure is still present (i.e. water in oil, bypassing filter, etc.). • Always fill the case with clean fluid before starting a new or serviced pump (fill as high as inlet port will allow on a PAVC style pump). For flooded suction, purge air from suction lines by cracking the inlet fitting or vent plug on pump body. This should prevent an airlock condition and allow for faster priming. • Check for proper shaft rotation, if there is a possibility it may have changed during a system rebuild. • Start pump with an open circuit whenever possible. Reduce the compensator to its minimum setting during start-up. Cycle the pump ON and OFF stroke while increasing the compensator to its required setting. This will assist in break-in of new components and help purge air from the case.
