Maintenance
Triplex Ceramic Plunger Pump Maintenance
1 The triplex ceramic plunger pumps (pump skids with Giant pumps) are oil lubricated and
require maintenance. The pump has a break-in period of 50 hours. After this time has
elapsed, the crankcase oil must be changed.
The service indicator light will not illuminate to indicate that the break-in period has elapsed.
2 After the initial break-in period, the oil must be changed every 500 hours. The Service
indicator light will illuminate after 400 hours of run time. The pump will then continue to run
for another 100 hours before shutting down. The service and fault indicator lights will
illuminate to indicate this condition.
3 Remember 500 hours is:
 Every 9 weeks if operated for 8 hours every day.
 Every 3 weeks if operated continuously for 24 hours per day.
