1.5 INTENDED USE
The pump should only be used for pumping the media it was selected for and within the limits
specified in the technical datasheets. Any other application beyond the intended use or conversion of
the pump without written agreement with the manufacturer shall be deemed to be not in accordance
with the intended use.
The pump may only be started up for the first time if it has been ensured that all safety devices are
completely fitted and functional.
If any areas are subject to have the risk of explosion, the relevant explosion-proof designed pumps
should be used.
Intended use also covers compliance with the conditions of operation, servicing and maintenance
specified by the manufacturer.
The pump is only to be put into operation filled with medium to be pumped.
Before starting up ensure that:
- Open the valves on the suction side completely to avoid cavitation and,
- Open the valves on the discharge side completely to avoid exceeding the permitted differential
pressure of the pump
- Discharge-side safety measures should be done (e.g. safety valve) to protect the pump from
non-permitted excess pressure
- Protection against contact for hot, cold and moving parts must not be removed during operation
1.6 TYPE DESIGNATION
The type designation can be found on the pump name plate and also on both the order confirmation
and customer invoice.
Example (an X in the code denotes a special version):
Type: ZP/120-213/114
ZP: pump series
120: pump type
213: speed of the pump when the motor operates at 50Hz
11: motor power in kW multiplied by ten (11 = 1.1 kW)

5
4: number of poles of the motor
Mat. Code: (BW-120) D37SSVQ
BW: rotor type (BW = bi-wing)
120: temperature class of the pump (Deg. C)
D: type of couplings (D = DIN 11851, B = BSP, E = DIN 2642, F = DIN 2576, R = RJT, S = SMS,
I = IDF, T= Tri-Clamp ISO2852, M = Tri-clampASME BPE, O = Tri-clamp ISO, N = ANSI flanges,

reducer aligned on base plate with cover)
Moreover, the year and week of construction, the pump serial number (to be stated when ordering
spare parts), the weight, maximum operating temperature and maximum differential head are also
marked on the name plate.
1.7 SOUND PRESSURE LEVEL
The sound-pressure level of the pump, operating at 50Hz without cavitation measured at 1m is less
than 70dB(A). In order to minimize noise and vibration, no other parts of the machine may vibrate at
the same time as the pump. The best solution is therefore to allow the pump to rest directly on the
concrete floor, or to fit shock absorbers between the pump and the frame of the machine.
1.8 CONSTRUCTION
ZP series Circumferential Piston Pumps can be ordered with bare shaft, i.e. pumps without motor or
base plate.
Or, ordered as a complete unit with drive motor, coupling & guard, base plate (or trolley) and layout
described as below.

1.9 PACKAGING & TRANSPORT
ZP series are shipped in non-returnable wooden packaging.
Unpack the pump/unit upon delivery and inspect it for visible transport damage.
Any damage occurred during the transport has to be immediately reported to the transport agent
after receipt of the consignment. Do not put the damaged products into operation.
The pumps need to be transported and secured with care to ensure no damage is caused. Lifting
equipment (hoist) and load securing straps must be placed with sufficient load capacity.
Make sure you set the pump down on a stable, horizontal surface.
Below a picture of a complete unit with drive & baseplate is shown as an example.
1.10 STORAGE
If the pumps need to be stored temporarily, they should be preserved under normal environmental
conditions and must not be exposed to the weather for any significant period of time.
Heed below measures when a longer storage period is required.
1. Protect pumps against dust, dirt, water or any other harmful environmental factors. Coat all
non-painted surfaces with acid-free and resin-free grease.
2. Do not grease stainless steel parts and non-metallic parts.
3. Cover all openings of pressure and suction ports.
4. Drain water when using it as flushing/quench medium for the shaft seal.

No danger
Ignitable liquid
•Flushed mechanical seal
•or single seal with preventive
maintenance by the customer
The flashpoint of a combustible liquid is the lowest temperature at which sufficient vapor is created
above a combustible liquid so that it can ignite when mixed with air. However, be aware that the
temperature of certain spots on the pump (e.g. the mechanical seal or motor) could be warmer than
the temperature of the circulated liquid. Therefore, if the flashpoint of the liquid is above the
temperature the liquid is pumped but below 135°C, it should also be considered as ignitable when
considering the risk leakage.
Please be aware that if a mechanical seal runs dry, the temperature of the seal faces can rise above
400°C.
Pumps with flushed mechanical seal:
You have to make sure there is a continuous circulation of the flushing liquid and the motor is
stopped immediately in case of lack of flushing liquid. Otherwise the mechanical seal can run
dry and generate dangerous high temperatures. When a quench reservoir is applied, the level
of the flushing liquid in the quench reservoir must be guarded by an ATEX approved level
sensor. If the level becomes too high or too low, the pump must be stopped. The temperature
in the quench reservoir should be guarded by an ATEX approved temperature sensor. The
temperature of the flushing liquid should be kept below 60°C. If necessary an external cooling
system should be used to keep the flushing temperature under 60°C. It is the responsibility of
the end user to use a suitable flushing liquid for the mechanical seals. The mix of the flushing
liquid and the pumped liquid must not create any dangerous or explosive gasses.
The pump should never run with closed valve.
Pumps with single mechanical seal:
You must monitor the flow (e.g. with an ATEX approved flow sensor on the inlet of the pump).
If there is no flow detected, you must stop the motor immediately.
Leakage of an ignitable liquid is a serious safety risk. The end-user has to evaluate the
consequences of the leak and adjust the check frequency for leak of the mechanical seal. In
case leak is detected, the pump must be stopped and the mechanical seal has to be replaced.
The mechanical seal has to be replaced preventively every 3000 operating hours.
The baseplate of the pump must be earthed in order to prevent a build-up of static
electricity.
The pump must not pump liquids warmer than 108°C.
The pump should not be started before compliance with all these safety measures.

3 INSTALLATION
3.1 INSTALLATION
1. The mounting surface should be flat and level.
2. Ensure at least 0.5 m clearance around the pump.
3. Normally, pump and drive unit are assembled on a baseplate. If you want another
configuration, feel free to contact PACKO.
4. To check the direction of rotor’s rotation, start and stop the motor for a short time.
5. Before connecting the pipelines, check the location of suction and discharge.
6. Ensure the pipelines are connecting correctly and tightly.
7. The suction line should be kept as short as possible and present minimum friction loss.
8. To check the working condition correctly, we recommend installing a pressure relieve valve
and pressure gauge at discharge line.
9. Suction and discharge lines must be fully supported and installed so that no expansion or
shock forces act on the pump which could lead to distortion.
10. Ensure sufficient clearance around the motor and pump.
11. The coupling alignment must be checked and readjusted if necessary.
3.2 CONNECTION OF THE MOTOR
The electrical connections may onlybe made when no electrical power is connected and by qualified
personnel in accordance with EN 60204 and the local regulations. Special attention must be paid to
optimal earthing of the motor; this must be performed in accordance with the applicable regulations
in the relevant country. Check on the name plate of the motor whether the motor can operate from
the available voltage and frequency.
The connecting cables and the protection system against excessive currents must be chosen
according to the data on the name plate of the motor. The voltage drop during the starting of the
motor may not exceed 3 %.
Tighten the nuts of the connector terminals in accordance with the torque values (Nm) stated below:

Do not install anywashers or nuts betweenthe cable lugs of the motor windings andthe cable lugs of
the connecting cables.
Inspect the seal of the gland. The gland must match the diameter of the connecting cable used.
Bending of the cable beside the gland must not allow water to penetrate. (Allow the cable to be
routed downwards when it leaves the motor.)
Connect the motor in star or delta according to the designation on the name plate of the motor and in
accordance with the diagram that is installed in the terminal box. Do not connect the motor if you
have any doubts regarding the interpretation of the connection diagram. If in doubt please contact
PACKO. Never check the direction of rotation of the pump when the terminal box is open. The

11
technician is responsible for complying with the regulations relating to electrical compatibility in the
country where the pump is installed.
The voltage and the frequency stated on the name plate of the motor must be observed. (Tolerance
of 5 % for the voltage, and 1 % for the frequency.)
For pumps whose power exceeds 7.5 kW, special starting provisions must be provided (star-delta
starter, soft starter, or starting with frequency converter).
The installation of an overcurrent protection device is always mandatory.
3.3 CONNECTING THE FLUSHING MECHANICAL SHAFT SEAL
In a pump with flushing, the sliding surfaces of the mechanical seal are lubricated and/or cooled by
a different liquid than the pumped liquid. This flushing liquid is supplied and discharged via the two
connections in the pump casing.
Either connect the water supply to one of the connections. Adjust the flow so that the water drips
slowly from the other connection (± 10 liters / hour). Preferably, a hose is placed at the outlet to drain
the leak next to the pump. Never provide a valve or throttle in the flushing liquid outlet to prevent
pressure build-up in the flushing chamber.
Or connect the flush to a quench reservoir of at least 5 liters. To ensure adequate circulation of the
flushing liquid, its viscosity must not exceed 100 centiPoise, the hoses used must have an internal
diameter of at least 14 millimeters and the hoses together must not be more than 2 meters in length.
There must be no bridges in the hoses where air can accumulate and thus hinder circulation. Place
the reservoir approximately 70 centimeters above the pump. The connection of both hoses to the
reservoir must be below the fluid level. Refill the quench container regularly and check for proper
circulation. When the temperature in the reservoir rises above 60 ° C, it must be cooled or switched
to a flow-through quench as described above.
In both cases, the pressure in the flushing chamber must never exceed 0.5 bar!
3.4 START UP
1. Before connecting the suction and discharge pipe work the entire system must be thoroughly
cleaned to prevent damage from welding, grinding and other residues.
2. Before starting, bump the motor to check if the motor fan is rotating clockwise or
counterclockwise when seen from the motor back. (Bump means to momentarily apply power
to the motor and then immediately remove power).
3. Direction of rotating must only be checked with a completely filled system. Where double
mechanical shaft seals are installed the flush supply must be operational. Any dry running will
result in seal damage.
4. The motor rating plate should be checked to ensure that it is in accordance with the available
electrical supply. It is essential that the full load current is not exceeded to prevent motor
overload.
5. Before start up any safety guards required by local statutory regulations should be fitted.
6. The pump must never be driven against a closed discharge valve. Please make sure the
pressure at the discharge does not exceed the maximum pressure as indicated on the
nameplate of the pump. The installation of a pressure relieve valve is recommended.
Pay attention to circumstances that could indicate pump cavitation:
1. Low pressure in the suction line due to bad suction conditions.

12
2. Air in the suction inlet line.
3. Pumping temperature is too high.
4. Pump is oversized.
4 CHECK THE PUMP ROTATION
4.1 PRINCIPLE OF OPERATION
-The pumps are of the positive displacement rotary type with lobed rotors. The volume at the
inlet increases when the rotors rotate and the product is drawn into the pump. It is then
transported in the space between the lobes and the periphery of the pump casing to the
discharge side. The volume between the rotors is reduced here and the product is forced out
through the outlet.
4.2 DIRECTION OF ROTATION
-The direction of flow is dictated by the direction of rotation of the drive shaft. Reversing the
direction of rotation will reverse the flow direction. Top and bottom shaft drive.

5.2 CLEANING
1. Before cleaning the pump, wear rubber gloves and protective glasses.
2. During CIP and SIP process, do not touch the pump and pipelines.
3. Ensure velocity rate of the CIP solutions is adequate to clean entire circuit. For most
applications a velocity of 1.5 m/sec is sufficient. For the CIP solution to achieve the proper
velocity, the pump drive must have enough speed range and horsepower. The required inlet
pressure also must be satisfied. If the pump does not supply enough CIP solution velocity, a
separate CIP supply pump with an installed bypass may be used.
4. Refer to the below CIP and SIP process.

6 MAINTENANCE
6.1 ROTOR CASE DISASSEMBLY
Prior to removal of the pump, the shut-off valves in the suction and discharge pipe work must be
closed. If there is any risk that product may be hardened, crystallized or frozen in the pump, it should
be thoroughly drained and cleaned immediately after use. Similar attention must be applied to the
seal flushing system. An authorized electrician should remove power before servicing to prevent
from any unintended start of the pump.
Reference numbers are indicated in the exploded view in chapter 8.
Remove the front cover and O-ring after removing the four cap
nuts from the front cover. If it is stuck, tap on the front cover
with a soft mallet and pull out.
If the front cover was stuck at the dowel pins, insert a flat driver
in the two grooves between front cover and rotor case to open
the pump.
Place a plastic round bar between the rotors and remove the
rotor bolts with the rotor bolt extraction tool. To avoid
damaging the rotor bolt, the extraction tool should be
positioned in the groove properly and pushed in strongly.
Turn the rotor bolts counter-clockwise and remove them.
The rotors can be removed from the pump casing by pulling
straight.
If they are stuck tight, alternately tap on the back of the inlet
and outlet ports with a soft mallet after removing the four hex
nuts of the stud bolts securing the case to the gearbox.
Treat the rotors carefully to avoid damage.
Remove the rotating seal rings from the backside of the rotors
as shown in Figure 4. Then, the O-rings can be removed.
Fig. 1
Fig.2
Fig. 3
Fig. 4

16
Clean and examine all of the pump components for damage. Replace damaged
components as required. PACKO recommends replacing all the wetted elastomers
during reassembly.
If you want to replace the seal ring only, you can remove the old one & insert the new
one easily just after removing the rotors without dismantling the rotor case.
Refer to chapter 6.3 for the further procedure.
In case you want to remove the seal body, it can be easily
dismantled from the rotor case after removing the stationary seal
ring and O-ring of the rotor case.
After pulling out both rotors and four hex nuts, the rotor case can
be separated by sliding along the stud bolt and pulling out from
the gearbox. Inspect the rotor case for wear, clean and continue to
seal maintenance (Refer to chapter 6.3), if needed.
If it is stuck tight, tap alternately on the back of the inlet and outlet
ports using a soft mallet as shown in Figure 7.
After the rotor case has been removed, handle and place carefully
the top & bottom shim(s). Keep track of their position in order to
avoid misalignment and to keep the right clearances between
rotors and rotor case.
They are installed accordingly at the factory for that particular
body.

6.2 INSPECTION
While performing standard maintenance or cleaning, check for signs of damage or extreme wear.
A simple inspection may show signs of a problem long before it becomes a serious issue. Detection of
such problems can avoid costly repairs and reduce down time.
1. Inspect O-rings and seals for re-use. Worn O-rings and seals should be replaced.
2. Inspect seal faces for chipping, scratches or cracks. Replace any seal faces if damaged.
3. Check the mating faces of the shaft and rotor for any damage.
4. Inspect rotor galling sign among the rotor case, front cover and rotors. Signs of galling must
be removed or damaged parts must be replaced.
5. Inspect the rotor bolt groove for burrs. Burrs must be removed or damaged parts replaced.

18
6.3 SEAL MAINTENANCE
Check & inspect all components of the seal replacement kit carefully whether there is any damage or
defect before installing. If any chipping, crack or scratch found during inspection, do not reuse them
and replace the damaged one.
Below shows the Single mechanical seal (Figure 9), Double mechanical seal (Figure 10) and PTFE
Triple lip seal with ceramic coated sleeve (Figure 11).
The seal ring can be easily removed from the rotor by hand. This
is common for the Single mechanical and Double mechanical seal.
Put the rotor face down on the table and pull out the seal ring and
O-ring from the rotor.
Pre-assemble the NEW O-ring and seal ring and then insert into
the rotor.
When inserting the seal ring, the pin of the rotor has to fit in the
hole of the seal ring.

Fig. 13

19
Single Mechanical Seal Maintenance
Remove the Seal ring from the rotor case & rotor and inspect
them. If any seal is damaged, do not re-use and replace it.
Clean both shaft ends and the rotor case before assembling. After
rotor case assembly, push the replacing NEW Seal ring into the
rotor case O-ring and turn it until the seal pins on the seal body fit
in the groove in the seal ring (Refer to ‘chapter 6.4’).
In order to disassemble the current seal body, pull out the current
O-ring and seal body sequentially.
Insert the replacing NEW seal body and O-ring into the rotor case
sequentially.
See ‘Rotor Case Assembly’ (chapter 6.4) to continue.
