4 Preventive Maintenance
4.1 OVERVIEW
Hale RSD Single-Stage PTO Pumps require very little care and maintenance.
However, the little required is extremely important. Preventive maintenance
tasks require very little time to accomplish and consist mainly of testing for
leaks, lubrication, and cleaning.
The following procedures are for normal use and conditions. Extreme condi-
tions may indicate a need for increased maintenance. The procedures in this
section identify measures needed to ensure lengthened pump life and continu-
ing dependability. Always follow local maintenance and test procedures.
4.2 POST OPERATION
1. Inspect the suction hose rubber washers and washers in the suction tube
caps. Remove foreign matter from under these washers. Replace worn,
damaged, or dry washers.
2. Verify that all discharge valves, booster line valves, drain valves, and cocks
are closed.
3. Tighten suction caps.
4.3 EXTREME CONDITIONS
Extreme conditions occur when the pump has been operated during freezing
weather or as a result of pumping from a water source that contains material
that is harmful to the pump if not purged.
During Freezing Weather
In freezing weather, drain the pump as follows:
1. Open all discharge and suction valves, remove suction tube caps and dis-
charge valve caps.
2. Open pump body drain cocks and/or Hale multiple drain valve.
