1 Description, application and working principle
1.1 Description
WARNING: This manual is intended to give Important Information that must be followed
during Storage, Transportation, Installation, Operation and Maintenance of the Pump-Set.
We therefore recommend that this manual is read carefully before the Pump-Set is put into
operation. To prevent damage being caused by inappropriate or incorrect use, or by being
used outside the normal operating parameters of the Pump-set, the Instructions in this
manual must be followed. Failure to do so may lead to damage to or premature failure of the
Pump-set and may cause Injury. Any such actions will invalidate the warranty.
The PT series piston pumps have been designed for vertical and horizontal dewatering applications.
These high efficiency positive displacement pumps are self-priming and suitable for pumping a mix of
water andair under anyconditions.Furthermore, these pumpscanrun drywithout damage orexcessive
wear to any part of the unit. The data sheet that accompanies the pump includes all data for the pump
unit. Before the pump unit is connected, an assessment must always be made to determine whether it
is suitable for the intended application.

1. Suction side
2. Pressure side
3. Lifting eye
4. Stone cather
5. Frame
6. Vacuum gauges

1.3 Intended use
The PT series piston pump is only intended for pumping water from filters or drainage
hose(s),NOT for pumping dirty water drawn directly from the suction hose, with or without a strainer.
Long fibres will cause immediate malfunctions. The maximum permissible particle size is 5 mm.
Contamination results in accelerated wear of the gland packing, gaskets, valve seals, cylinder sleeves
and piston cups.
ThePT series piston pumps are suitable for pH-neutral water (pH value 7) at a maximum temperature of
30°C (86°F) and not for chemically polluted water or water with a pH value higher than 7.
1.4 Unintended use
− It is not permitted to use the pump unit for pumping salt water.
− It is not permitted to use the pump unit for pumping liquids containing larger suspendedsolids.
− It is not permitted to use the pump unit for pumping flammable and/or explosive substances.
− Itis notpermitted todeployastandard pump unitinan environment in which there is adanger of fire
and/or explosion.
− It is not permitted to deploy a standard pump unit in an ATEX environment.
− Use the pump unit only for those applications listed on the specification sheet for the pumpunit.
− It is not permitted to use the pump unit for any application and/or field of activity other than that for
which the pump unit was originally specified and installed without written permission from BBA
Pumps.

2 Safety instruction
This manual contains warning and safety symbols. Do not ignore the instructions. They are provided
for the benefit of your health and safety and to prevent damage to the environment and the pump unit.
DANGER
When the danger symbol with the text DANGER is shown, it is accompanied by
information that is of great importance for the safety of everyoneconcerned.
Ignoring the information can result in injury (possibly severe) or evendeath.
WARNING
When the warning symbol with the text WARNING is shown, it is accompanied
by information that is of great importance for everyone concerned with the pump
unit. Ignoring the information can result in injury or damage (possibly severe) to
the pump
unit.
The pump unit conforms to the European Machinery Directive. However, this does not exclude the
possibility of accidents if used incorrectly.
Useof the pump for an application and/or deployment of thepump in anenvironment other than defined
at the time of purchase is strictly prohibited and can result in a hazardous situation.
This is particularly true for corrosive, toxic or other hazardous liquids. The pump unit may only be
installed, operated and maintained by persons who have received appropriate training and are aware
of the associated dangers.
The installer, operator and maintenance personnel must comply with the local safety regulations. The
company management is responsible for ensuring that all work is performed by qualified personnel in
a safe manner. It is not permitted to make changes to the pump unit without written permission from
BBA Pumps.
If any changes are made to the pump without the written permission of BBA Pumps, BBA Pumps
disclaims all liability. Hearing protection must be worn if the noise emission level exceeds 85 dB(A).
Ensure that hot/cold and rotating parts of the pump are shielded adequately to prevent unintentional
contact.
It is not permitted to start the pump if such guards are missing or damaged.
The company management must ensure that everyone who works with/on the pump unit is aware of the
type of liquid that is being pumped. These persons must know what measures are to be taken in the
event of leakage.
Dispose of any liquids that have leaked, in a responsible manner. Observe local regulations
Never allow the pump unit to run with a blocked discharge line. The heat build-up could lead to an
explosion

3 Lifting instructions PT250 pump unit
DANGER
Never walk under a raised load. This can result in a life-threatening situation.
WARNING
Always disconnect all external connections before moving the pump unit.
WARNING
Neither the lifting eye on the engine nor the lifting eye of the (bare shaft) pump may
be used for transport of the pump unit.
WARNING
Lifting forces must be as vertical as possible; the maximum lifting angle is 15°.
Pump unit in enclosure
There is a lifting eye located on the top of the enclosure. Only lift the unit from this lifting eye.
WARNING
If the pump unit is installed on a swampy or muddy surface, the installation
may be ‘stuck’ to the ground.
DANGER
NEVER move or lift the pump unit by the angle profiles on top of the enclosure or
stacking frame.
