Note:
Each system’s maintenance cycle will be unique. If
system performance decreases, check immediately. If no wear
at 500 hours, check again at 1000 hours and each 500 hours
until wear is observed. Valves typically require changing every
seal change. Duty cycle, temperature, quality of pumped liquid
and inlet feed conditions all effect the life of a pump’s wear
parts and service cycle.
Note: Remember to service the regulator/uploader at each
seal servicing and check all system accessories and connections
before resuming operation.
