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 drain lines are
piped together to a multi-drain to allow the entire system 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 and/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 necessary. Reassemble the pump and test for
proper operation. (Also see separate manual provided.)
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 ESP 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 Table 4-3: “Pump Ratings (GPM / LPM)” on page 55.)
A pump must be able to pump FULL rated capacity at 150 PSI (10 BAR), 70%
capacity at 200 PSI (14 BAR) and 50% capacity at 250 PSI (17 BAR).
Tank-to-Pump Flow Rate Test
Note: This procedure is provided as a reference only. It does not supersede any
local procedures.
1. Fill the water tank until it overflows.
2. Close the tank fill line, bypass the cooling line, and all the pump intakes.
