PREPARATION FOR START-UP
CHECKING ROTATION
▲
! CAUTION
Serious damage may result if pump is run in
the wrong rotation.
1. Unlock driver power.
2. Ensure all personnel are clear of area. Jog
driver just long enough to determine direction of
rotation. Rotation must corresponding to arrow
on pump casing.
PRIMING PUMP
Never start pump until properly primed (pump casing
and suction piping are full of liquid).
▲
! CAUTION
Operation without liquid in the pump will
damage the mechanical seal.
Your particular system will dictate method used to
prime pump.
STARTING PUMP
1. Make sure suction valve and any recirculation
lines are open.
2. Fully close or partially open discharge valve as
dictated by system conditions.
3. Start driver.
▲
! CAUTION
Immediately observe pressure gauges. If
discharge pressure is not quickly attained,
stop driver, reprime pump, and attempt to
restart.
4. Slowly open discharge valve until the desired
flow is obtained.
▲
! WARNING
Continuous operation against closed
discharge valve may vaporize liquid creating
an explosive hazard due to confined vapor
under high pressure and temperature.
▲
! CAUTION
Continuous operation against closed
discharge valve will cause pump to overheat.
