These Service Instructions apply to PUMPEX electric submersible
drainage pump models
P 601-701-801-1001-1501-2001 and 3001.
All configurations; including, centerline, high volume, normal head,
and high head.
Pump models P601 P 701 and P 1001 and P 2001 are available in
either 3-phase or single-phase operation; other models for 3-phase
operation only. All pumps for 3-phase operation are equipped for
D.O.L. start, and do not require an external start control. Model P
2001W is equipped as 230v 1-phase, and is supplied with a factory
control box.
Only
a factory supplied control box should be used on
this pump.
All 3-phase pumps are fitted with a built-in contactor unit and thermal
switches in the stator windings, connected in series with the contactor
coil. Single phase pumps have start capacitors or factory supplied
control box. In case of the motor overheating, the thermal switches
open and disconnect the contactor and the power supply to the pump.
Note!!
When the motor has cooled down the thermal switches close
and re-start the pump automatically.
Connection at the job site
Check that the pump is connected for the actual mains voltage.
Reconnection between 230 volts and 460 volt 3-phase is made by
changing the contactor coil and reconnect according to the wiring
diagram.
If the contactor is not equipped with a dual voltage contactor coil, the
coil must be replaced to coincide with the desired voltage at the site.
Separate external motor protector is not required, but fuses of correct
size should be installed as short-circuit protection. Use time lag fuses
according to the following table.
Check the direction of rotation in all 3-phase pumps. Tilt the pump and
start it. It should jerk in a counter clockwise direction as indiciated by
an arrow on the pump. If it jerks in the other direction, two phases
should be shifted. If the bottom of the sump is soft and muddy, place
the pump on some planks, put it into a bucket, or suspend it from a
rope to prevent it from digging itself into the mud.
Never lift or pull the pump by the electric cable.
Note!!
Harm to the
pump cable may cause injury or death.
Always
disconnect the pump from the power supply before opening
any part of the pump. Always use a qualified electrical technician
when servicing pump.
