ABS submersible sewage pump XFP 80C - 201G
5 Transport and Storage
5.1 Transport
During transport, care should be taken that the pump is not dropped or thrown.
The pumps of the XFP series are fitted with a lifting hoop to which a chain and shackle may be attached for
transport or for suspension of the pump.
The pump must be raised only by the lifting hoop and never by the power cable.
Take note of the weight of the entire unit. The hoist and chain must be adequately dimensioned for
that weight and must comply with the current valid safety regulations.
All relevant safety regulations as well as general good technical practice must be complied with.
5.2 Storage
During long periods of storage the pump should be protected from moisture and extremes of cold or heat.
To prevent the mechanical seals from sticking it is recommended that occasionally the impeller is rotated by
hand.
If the pump is being taken out of service the oil should be changed before storage.
After storage the pump should be inspected for damage, the oil level should be checked, and the impeller
checked to ensure it rotates freely.
5.2.1 Moisture protection of motor connection cable
The motor connection cables are protected against the ingress of moisture along the cable by having the ends
sealed at the factory with protective covers.
ATTENTION! The ends of the cables should never be immersed in water as the protective covers
only provide protection against water spray or similar (IP44) and are not a water tight
seal. The covers should only be removed immediately prior to connecting the pumps
electrically.
During storage or installation, prior to the laying and connection of the power cable, particular attention should
be given to the prevention of water damage in locations which could flood.
ATTENTION! If there is a possibility of water ingress then the cable should be secured so that the
end is above the maximum possible flood level. Take care not to damage the cable or
its insulation when doing this.

6 Mounting and Installation
The regulations covering the use of pumps in sewage applications, together with all regulations
involving the use of explosion-proof motors, should be observed.The cable ducting to the control panel
should be sealed off in a gas-tight manner by the use of a foaming material after the cable and control
circuits have been pulled through. In particular the safety regulations covering work in enclosed areas
in sewage plants should be observed together with general good technical practice.
For the XFP transportable version, arrange the cable run so that the cables will not be kinked or nipped.
Connect the discharge pipe and cable (see section ”Electrical Connection”). Place the pump on a firm surface
which will prevent it from overturning or burrowing down. The pump can also be bolted down to the base or
suspended slightly by the lifting handle. Hoses, pipes and valves must be sized to suit the pump performance.

ABS submersible sewage pump XFP 80C - 201G
6.2 Discharge Line
The discharge line must be installed in compliance with the relevant regulations.
DIN 1986/100 and EN 12056 applies in particular to the following:
- The discharge line should be fitted with a backwash loop (180° bend) located above
the backwash level and should then flow by gravity into the collection line or sewer.
- The discharge line should not be connected to a down pipe.
- No other inflows or discharge lines should be connected to this discharge line.
ATTENTION! The discharge line should be installed so that it is not affected by frost.
7 Electrical Connection
Before commissioning, an expert should check that one of the necessary electrical protective devices
is available. Earthing, neutral, earth leakage circuit breakers, etc. must comply with the regulations
of the local electricity supply authority and a qualified person should check that these are in perfect
order.
ATTENTION! The power supply system on site must comply with VDE or other local regulations
with regard to cross-sectional area and maximum voltage drop. The voltage stated on
the nameplate of the pump must correspond to that of the mains.
The power supply cable must be protected by an adequately dimensioned slow-blow fuse corresponding to the
rated power of the pump.
The incoming power supply as well as the connection of the pump itself to the terminals on the control
panel must comply with the circuit diagram of the control panel as well as the motor connection
diagrams and must be carried out by a qualified person.
All relevant safety regulations as well as general good technical practice must be complied with.
ATTENTION! For use in the open air, the following VDE regulations apply:
Submersible pumps used outdoors must be fitted with a power cable of at least 10 metre length. Other
regulations may apply in different countries.
For pumps intended to be used in outdoor fountains, garden ponds and similar places, the pump is to be
supplied through a residual current device (RCD) having a rated residual operating current not exceeding
30 mA.
Please consult your electrician.
7.1 Temperature monitoring
Thermal sensors in the stator windings protect the motor from overheating.
XFP motors are fitted with bimetallic thermal sensors in the stator as standard, or as an option with a PTC
thermistor (in accordance with DIN 44082). PTC relays for use in control panels must also be in accordance
with this standard.
7.2 Seal monitoring
XFP pumps are supplied as standard with a moisture sensor (DI), to detect and alert to the ingress of water into
the motor and seal chambers (PE1 & PE2), or motor and dry chambers (PE3).
NOTE: Running the pump with the thermal and/or moisture sensors disconnected will invalidate
related warranty claims.

12 Installation, Operating and Maintenance Instructions (Original Instructions)
ABS submersible sewage pump XFP 80C - 201G
8 Commissioning
Before commissioning, the pump should be checked and a functional test carried out. Particular attention should be
paid to the following:
- Have the electrical connections been carried out in accordance with regulations?
- Have the thermal sensors been connected?
- Is the seal monitoring device correctly installed?
- Is the motor overload switch correctly set?
- Does the pump sit correctly on the pedestal?
- Is the direction of rotation of the pump correct - even if run via an emergency
generator?
- Are the switching ON and switching OFF levels set correctly?
- Are the level control switches functioning correctly?
- Are the required gate valves (where fitted) open?
- Do the non-return valves (where fitted) function easily?
8.1 Types of operation and frequency of starting
All pumps of the XFP series have been designed for continuous operation S1 when either submerged or dry-
installed.
8.2 Checking direction of rotation
When three phase units are being commissioned for the first time, and also when used on a new site, the
direction of rotation must be carefully checked by a qualified person.
When checking the direction of rotation, the pump should be secured in such a manner that no danger
to personnel is caused by the rotating impeller or by the resulting air flow. Do not place your hand into
the hydraulic system!
When checking the direction of rotation, or when starting the unit, pay attention to the START
REACTION. This can be very powerful and cause the pump to jerk in the opposite direction to the
direction of rotation.
ATTENTION:
When viewed from above, the
direction of rotation is correct
if the impeller rotates in a
clockwise manner.
NOTE:
The start reaction is
anti-clockwise.
ATTENTION! If a number of pumps are connected to a single control panel then each unit must be
individually checked.
ATTENTION! The mains supply to the control panel should have a clockwise rotation. If the leads
are connected in accordance with the circuit diagram and lead designations, the
direction of rotation will be correct.

13Installation, Operating and Maintenance Instructions (Original Instructions)
ABS submersible sewage pump XFP 80C - 201G
8.3 Changing direction of rotation
The direction of rotation should only be altered by a qualified person.
If the direction of rotation is incorrect then this is altered by changing over two phases of the power
supply cable in the control panel. The direction of rotation should then be rechecked.
9 Maintenance
Before commencing any maintenance work the pump should be completely disconnected from the mains
by a qualified person and care should be taken that it cannot be inadvertently switched back on.
When carrying out any repair or maintenance work, the safety regulations covering work in enclosed areas
of sewage installations as well as good general technical pratices should be followed.
Under continuous running conditions the pump motor housing can become very hot. To prevent burn
injury allow to cool down before handling.
ATTENTION! The maintenance instructions given here are not designed for “do-it-yourself” repairs as
special technical knowledge is required.
9.1 General maintenance instructions
ABS submersible pumps are reliable quality products, each being subjected to careful final inspection.
Lubricated-for-life ball bearings, together with monitoring devices, ensure optimum pump reliability provided that
the pump has been connected and operated in accordance with the operating instructions. However, should a
malfunction occur, do not improvise, but ask your ABS Customer Service Department for assistance.
This applies particularly if the pump is continually switched off by the current overload in the control panel, by
the thermal sensors of the thermo-control system, or by the seal monitoring system (DI).
Regular inspection and care is recommended to ensure a long service life. Service intervals vary for XFP
pumps depending on installation and application. For recommended service interval details contact your local
ABS Service Centre. A maintenance contract with our Service Department will guarantee the best technical
service.
When carrying out repairs, only original spare parts supplied by the manufacturer should be used.
ABS warranty conditions are only valid provided that any repair work has been carried out in an ABS approved
workshop and where original ABS spare parts have been used.
NOTE: XFP pumps are rated for use in hazardous locations (Ex) as standard and feature a
secondary Ex nameplate containing EX data. If an XFP pump is serviced or repaired
in a workshop that is not Ex approved then it must no longer be used in hazardous
locations and the Ex nameplate must be removed.
9.2 Maintenance of Lifting Stations in accordance with EN 12056.
It is recommended that a lifting station is inspected monthly and its function checked.
In accordance with EN regulations, the lifting station should be maintained by a qualified person at the following
intervals:
in commercial premises - every three months.
in apartment blocks - every six months.
in a single family home - once a year.
In addition we recommend that a maintenance contract be taken out with a qualified company.

9.3 Lubricant changing (PE1 & PE2)
The seal chamber between the motor and the hydraulic section has been filled with oil at manufacture.
An oil change is only necessary:
At specified service intervals (for details contact your local ABS Service Centre).
If the DI moisture sensor detects an ingress of water into the seal chamber or motor chamber.
After repair work that requires draining of the oil.
If the pump is being taken out of service the oil should be changed before storage.
9.3.1 Instructions on how to drain and fill the seal chamber
Loosen the drain plug screw (a) enough to release any pressure that may have built-up, and re-tighten.
Before doing so, place a cloth over the plug screw to
contain any possible spray of oil as the pump de-pressurises.
Place the pump in a horizontal position, sitting on its discharge flange,
with the motor housing supported from underneath.
To prevent the pump from toppling over ensure it is supported
to lie flat on its discharge flange.
Position an adequate container to receive the waste oil.
Remove the plug screw and seal ring (a) from the drain hole.
After the oil is fully drained lay the pump flat, and rotate so that
the drain hole is positioned to the top.
When in this position the pump must be held by hand,
or supported at both sides, to prevent it from toppling over.
Select the required volume of oil from the quantities table (p.17) and
slowly pour into the drain hole.
Refit the plug screw and seal ring. (a) Drain plug screw

water and propylene glycol is frost resisting down to -15 °C / 5 °F.
A glycol change is only necessary:
At specified service intervals (for details contact your local ABS Service Centre).
If the DI moisture sensor detects an ingress of water into the seal chamber or dry chamber.
After repair work that requires draining of the glycol.
If the pump is being taken out of service the glycol should be changed before storage.
In the case of extreme ambient temperatures below -15 °C / 5 °F (e.g. during transport, storage, or if the
pump is out of duty) the cooling liquid must be drained. Otherwise the pump may be damaged.
9.4.1 Instructions on how to drain and fill the seal chamber
Loosen the drain plug screw (a) enough to release any pressure that may have built-up, and re-tighten.
Before doing so, place a cloth over the plug screw to contain
any possible spray of glycol as the pump de-pressurises.
Secure a hoist to the lifting hoop. Lay the pump on its side and
rotate until the drain plug is underneath.
Note: because there is insufficient space to place a waste
container underneath the drain plug the waste must be drained
into a sump.
Remove the plug screw and seal ring (a) from the drain hole.
After the glycol is fully drained, place the pump in a horizontal
position sitting on its discharge flange with the motor housing
supported from underneath.
To prevent the pump from toppling over ensure it is

9.5 Coolant changing (PE3 - version with cooling jacket)
The cooling system (seal chamber and cooling jacket) has been filled with glycol at manufacture. The water and
propylene glycol is frost resisting down to -15 °C / 5 °F.
A glycol change is only necessary:
At specified service intervals (for details contact your local ABS Service Centre).
If the DI moisture sensor detects an ingress of water into the seal chamber or dry chamber.
After repair work that requires draining of the glycol.
If the pump is being taken out of service the glycol should be changed before storage.
In the case of extreme ambient temperatures below -15 °C / 5 °F (e.g. during transport, storage, or if the
pump is out of duty) the cooling liquid must be drained. Otherwise the pump may be damaged.
9.5.1 Instructions on how to drain and fill the cooling system
Loosen the plug screw (a) or (b), enough to release any pressure that
may have built-up, and re-tighten.
Before doing so, place a cloth over the plug screw to contain any
possible spray of glycol as the pump de-pressurises.
Secure a hoist to the lifting hoop. Tilt the pump to 45° with the drain
plugunderneath.
Note: because there is insufficient space to place a waste container
underneath the drain plug by the completion of step 5, the waste
must be drained into a sump.
Remove the plug screw and seal ring (a) from the drain hole.
Glycol will drain from the cooling jacket chamber.
When the flow stops, continue to gradually tilt the pump until
horizontal. This will drain the remaining glycol from the seal
chamber.
Note: draining the glycol entirely with the pump in a horizontal
position would result in some glycol being retained in the cooling
jacket.
After the glycol is fully drained raise the pump into its upright position
and refit the plug screw and seal ring (a).
Remove the plug screw and seal ring (b) from the fill hole.
Select the required volume of glycol from the quantities table and
slowly pour into the fill hole. (a) Drain (b) Fill

9.7 Bottom plate adjustment
At manufacture, the bottom plate is fitted to the volute with the correct clearance gap set between the impeller
and the bottom plate (for optimum performance max 0.2 mm).
9.7.1 Instructions on how to adjust the bottom plate
To reset the clearance gap following wear:
(Note: when adjusting PE3 pumps, steps 1, 2 and 3 do not apply)
Check the position of the alignment notch (e) in the fixing lug to determine if the bottom plate is in the fac-
tory pre-set position or if the clearance gap has been previously adjusted. If previously adjusted proceed to
Step 4.
Remove the three screws (c) sec uring the bottom plate to the volute.
Attention: if, due to corrosion, the bottom plate does not release freely from the volute, DO NOT force it
free by tightening the adjusting grub screws (d) against the fixing lugs on the volute as this could damage
the lugs on the bottom plate beyond repair! In that case, first remove the volute from the motor housing by
releasing the three securing screws (f) and then remove the bottom plate by tapping it free from inside the
volute using a mallet and block of wood.
Rotate the bottom plate anti-clockwise through 45° from the pre-set position (a) to the secondary alignment
position (b) and refit the securing screws.
Loosen the adjusting grub screws (d) and tighten the securing screws in the bottom plate evenly until the
impeller will lightly, but freely, rub against the bottom plate when rotated by hand.
Tighten the grub screws fully to secure the bottom plate in position (max. 33 Nm).

9.8 Bearings and Mechanical Seals
XFP pumps are fitted with lubricated-for-life ball bearings. Shaft sealing is by means of double mechanical
seals.
ATTENTION! Once removed, bearings and seals must not be re-used, and must be replaced in
an approved workshop with genuine ABS spare parts.
9.9 Changing the power cable (PE1 & PE2)
To facilitate quick and easy changing or repair of the power cable, the connection between the cable and motor
is by means of an integrated 10-pole terminal block.
To be carried out only by a qualified person, in strict adherence to relevant safety regulations.
9.10 Cleaning
If the pump is used for transportable applications, then in order to avoid deposits of dirt and encrustation it
should be cleaned after each usage by pumping clear water. In the case of fixed installation, we recommend
that the functioning of the automatic level control system be checked regularly. By switching the selection switch
(switch setting “HAND”) the sump will be emptied. If deposits of dirt are visible on the floats then these should
be cleaned. After cleaning, the pump should be rinsed out with clear water and a number of automatic pumping
cycles carried out.
9.11 Venting of the volute
After lowering the pump into a sump full of water, an air lock may occur in the volute and cause pumping
problems. To clear the air lock, raise the pump in the medium and then lower it again. If necessary, repeat this
venting procedure.
We strongly recommend that dry-installed XFP pumps are vented back into the sump by means of the (drilled
and tapped) hole provided in the volute.
