Cartridge seals:
Follow the appropriate lubrications directions (single seal or double seal) given in this section. Use the
cartridge seal gland flushing taps for your seal water connections. Most cartridge seals provide flushing
connections on their glands. The quench taps on the glands (if present) can be used when necessary. Con-
sult seal manufacturer's literature for more detailed information.
SECTION V. OPERATION
A. PRE-START CHECKS:
Before initial start of the pump, make the following inspections:
1. Check alignment between the pump and motor. See Section IV, F, for alignment requirements.
2. Check all connections to motor and starting device with wiring diagram. Check voltage, phase, and
frequency on motor nameplate with line circuit.
3. Check suction and discharge piping and pressure gauges for proper operation.
4. Check impeller adjustment, see Section VII, D for proper adjustment.
5. Turn shaft by hand to assure that it rotates freely.
6. Check stuffing box adjustment, lubrication and piping.
7. Check driver lubrication.
8. Assure that pump bearings are properly lubricated.
9. Assure that coupling is properly lubricated, if required.
10. Assure that pump is full of liquid (see Section V, B) and all valves are properly set and opera-
tional, with the suction valve open. Purge all air from top of casing.
11. Check rotation with coupling disconnected. Be sure that the driver operates in the direction
indicated by the arrow on the pump casing as serious damage can result if the pump is operated
with incorrect rotation. Check rotation each time the motor leads have been disconnected.
B. PRIMING:
If the pump is installed with a positive head on the suction, it can be primed by opening the suction and
vent valve and allowing the liquid to enter the casing.
If the pump is installed with a suction lift, priming must be done by other methods such as foot valves,
ejectors, or by manually filling the casing and suction line.
NOTE: under either condition the pump must be completely filled with liquid before starting. The pump
must not run dry in the hope it will prime itself.
Flushing:
New and old system should be flushed to eliminate all foreign matter. Heavy scale, welding splatter and
wire or other large foreign matter can clog the pump impeller. This will reduce the capacity of the pump
causing cavitation or excessive vibration.
