STARTING THE PUMP
Before attempting to start the pump,
check the water level in the well or sump
to be sure that the first impeller of the
pump is submerged. Do not operate the
pump if the first impeller is above the
standing water level. In this condition,
the pump cannot be expected to pump
water, and severe damage to the pump
may result.
Before attempting to start the pump,
check the readiness of the following
items:
Level of oil in the reservoir
Lubrication of the driver
Oil-cooling connections for the
driver (if applicable)
Wiring of electric motor (if
applicable)
Impeller adjustment
Discharge piping connection
Shut-off valve in discharge pipe –
should be ¼ open
Allow the sight valve to operate for
approximately ½ hour before starting the
pump. This is especially important if the
pump has been sitting idle for some time
after installation.
If the pump does not discharge air
or fluid immediately after start-up, shut
it down.
For pumps in which the enclosing
tube was tensioned by wrenching the
tube nut, check for leakage at the tube
nut gasket. If the gasket does not seal
properly, the tube nut must be tightened.
With the pump shut down, work through
the hand holes to tighten the tube nut to
ensure adequate seal at the gasket.
After the pump is started, check for
any unusual noises and excessive
vibration. If either is present, shut the
pump down and investigate the cause of
the problem.
If the pump is started with the check
valve open and the pump is operating
against the system head, slowly open the
discharge valve until the pump is
operating at its designed dis-charge
pressure. If the system head was
correctly calculated, the pump should
operate at its design condition with the
discharge valve completely open.
Operation of the pump away from
its intended design conditions could
have adverse effects on its efficiency and
service life.
