Preventive Maintenance

Check Drain Lines to Multi-Drain
Drains are supplied on the pump and piping at the lowest points where water
could collect and freeze, rendering the pump ineffective.
Most of these drains are piped together to a multi-drain to allow the entire sys-
tem to be drained by one valve.
It is necessary to inspect each line of the multi-drain to ensure the entire system
is draining when the valve is operated. Inspect each connection and verify the
individual lines to the multi-drain are free of debris. Repair or replace any lines
that are damaged, kinked, or corroded.
Clean Priming Pump
Disassemble the priming pump and clean the housing and vanes. Inspect the
vanes for wear and replace as needed. Reassemble the pump and test for
proper operation. (See separate manual provided, Hale p/n: 101-2850-02-0.)
IIMPORTANT !
DO NO USE A LUBRICANT ON THE PUMP VANES AND VANE SLOTS. LUBRI-
CANT AND COLD WATER FORM AN EVENTUAL GUMMY RESIDUE THAT REN-
DERS THE PRIMING SYSTEM INOPERATIVE. A COMPLETE AND THOROUGH
DISASSEMBLY AND CLEANING IS THEN REQUIRED.
Performance Testing Overview
The yearly standard performance test consists of checking the pumper,
(according to rating) at three capacities and comparing the results to when the
pump was first placed in service. This provides some measure of performance
deterioration, if any. (See Figure 4-3: “Pump Ratings (GMP/LPM).”)
