Applications

These starting and operating instructions are applicable to electric submersible pumps
specified on the cover. The pumps are intended for pumping water that may contain
abrasive particles.
c
DANGER! The pump must not be used in an explosive or flammable
environments or for pumping flammable liquids.
The pumps conform to the EU machine directive. See rating plate.
The manufacturer guarantees that a new pump will not emit airborne noise in excess of
70 dB(A) during normal operation, when either fully or partially submerged.
m
CAUTION!
The pump must not be run if it has been partially dismantled.
c
CAUTION! Earth leakage detector (RCD Residual-current device) is
recommended to be used when a person come in contact with either
the pump or the pumped media.
Special regulations apply for permanent installation of pumps in swimming
pools.

Product description

Limitations
Immersion depth: up to 20 m / 65 ft. Liquid temperature: up to 40°C / 104°F.
Motor
3-phase AC squirrel-cage induction motor for 50 or 60 Hz.
Level control
Some pumps can be equipped with float switch for automatic level control.
Motor protection
For built in motor protection, the thermal contacts in the motor are fitted to disconnect
the power at high temperature (140ºC/ 284ºF). The thermal contacts can as alternative
be connected to an external motor protection.
Electric cable
H07RN8-F, S1BN8-F or equivalent cable. If the cable is longer than 20 m, the voltage
drop must be taken into account. Note that the pumps can be supplied with different
cables and for different connection methods.
Handling
The pump can be transported and stored either vertically or horizontally. Make sure that
it is secured and cannot roll.
m
CAUTION! The pump must always rest on a firm surface so that it
will not overturn. This applies to all handling, transport, testing and
installation.
m
CAUTION! Always lift the pump by the lifting handle - never by the
motor cable or hose.
NOTE! Always protect the cable end so that no moisture will penetrate into the
cable. Water could otherwise seep into the terminal compartment or into the
motor through the cable.
If the pump is stored for a long period of time, protect it against dirt and heat.
After a longer period of storage, the pump must be inspected and the impeller must be
rotated by hand before the pump is taken into operation. Check the seals and cable
entry particularly carefully.
Installation
Safety measures
In order to reduce the risk of accidents during service and installation work, take ex-
treme care and bear in mind the risk of electrical accidents.
m
CAUTION! The lifting tackle must always be designed to suit the
pump weight. See under the heading "Product description".
Pump installation
Arrange the cable run so that the cables will not be kinked or nipped.
Connect the cable. Connect the delivery piping. Hoses, pipes and valves must be se-
lected to suit the pump delivery head.
Place the pump on a firm surface which will prevent it from overturning or burrowing
down. The pump can also be suspended by the lifting handle slightly above the bottom.

Electrical connections

The pump must be connected to terminals or starting equipment installed at a level at
which it cannot be flooded.
c
CAUTION! All electrical equipment must always be earthed (ground-
ed). This applies both to the pump and to any monitoring equipment.
c
CAUTION! The electrical installation must conform to national and
local regulations.
Check that the mains voltage, frequency, starting equipment and method of starting
agree with the particulars stamped on the motor rating plate.
N.B. A pump designed for 400V50Hz, 460V60Hz can be used in the 380-415V50Hz,
440-460V60Hz range. A pump designed for 230 volt can be used in the 220-245 volt
range.
Connection of stator and motor conductors
If the pump is not fitted with a connector, connect it in accordance with valid wiring
diagram. Wiring diagrams are included in the workshop manual.
Cable marking on pump cables:
L1, L2, L3 = phase marking at D.O.L start / U1, V1, W1, U2, V2, W2 = stator marking
at star-delta start / F0, F1, F3, F4 = thermal sensor marking / D1, D2 = leakage sensor
marking, must be connected to external relay / GC = ground check marking
The electrical installation shall be inspected by an authorized electrician.
Operation
Before starting:
Check the direction of rotation of the pump (see fig-
ure). At the instant of starting, the pump will jerk anti-
clockwise when viewed from above.
If the direction of rotation is incorrect, transpose two
phases.
m
CAUTION! The starting jerk may be violent. Don't hold the pump
handle when checking the direction of rotation. Make sure that the
pump is firmly supported and cannot rotate.
c
CAUTION! Reversal of the direction of rotation on a plug that has
no phase transposing device may be done only by an authorized
person.
m
CAUTION! If the built-in motor protection has tripped, the pump will
stop but will restart automatically when it has cooled down.
Service and maintenance
c
CAUTION! Before any work is started, check that the pump is iso-
lated from the power supply and cannot be energized.
Regular inspection and preventive maintenance will ensure more reliable operation. The
pump should be inspected every six months, but more frequently if the operating condi-
tions are difficult.
For a complete overhaul of the pump, please get in touch with an authorized Sulzer
workshop or your Sulzer dealer.
m
CAUTION!
If a cable is damaged, it must always be replaced.
m
CAUTION! A worn impeller often has sharp edges. Take care not to
cut yourself on them.
m
CAUTION! In the event of inward leakage, the oil housing may be
pressurized. When removing the oil plug, hold a piece of cloth over it
to prevent oil from splashing.
End-of-life units can be returned to Sulzer or recycled in accordance
with local regulations.
