ATTENTION
Pumps that do not stand steady or stable on
their own, should be mounted on a rigid
and stable base.
ATTENTION
Place the pump there where there is the
lowest risk for noise nuisance.
1. Place and install the pump on a level, stable surface in
a dry and frost-proof room.
2. Make sure that sufficient air can reach the cooling fan
of the motor. For this purpose the free space above the
cooling fan should be at least ¼ of the diameter of the
fan cover air intake.
3. Install the pump with counter flanges. Pumps with non-
standardised connections; counter flanges are delivered
separately.
4. Install a valve on the supply and on the delivery
connection of the pump.
5. If there is a chance that when the pump is standing still
the medium can flow back, it is advised to install a non-
return valve.
6. Make sure that the inlet of the pump is never clogged.
F-1.1) Indicators:
The arrow (A) on the pump foot indicates the flow direction
of the liquid. The arrow (B) on the top bracket indicates the
rotating direction of the motor.
F-1.2) Install bypass:
Install a bypass if the pump operates against a closed
valve. The required capacity of the bypass is at least
10% of the optimum volume flow. At high operating
temperatures a higher volume flow is required. Refer to the
table “Minimum volume flows” in the paragraph “Working
range”
F-2) Mounting a motor on the pump:
ATTENTION
It is to be advised to use a special designed
BP Pumps motor. Before installing an other
brand/standard IEC-norm motor, BP Pumps
has to be consulted to judge the applicability.
The motor has to conform to the following conditions:
• Increased power output (to limit the standard installed
motor power)
• Reinforced bearing at driven end (to withstand the axial
force)
• Fixed bearing at driven end (to minimize the axial play)
• Smooth shaft, no key lock (to improve the coupling grip
and to improve the motor balance)
The advised bearings per motor type are:
(HP) Axial Bearing (HP) Co-axial Bearing

F-2.1) Install the motor on pumps, supplied without
motor, with a standard mechanical seal:
1. Remove the “transport fixation assembly” together
with the coupling guards (681) and the coupling shells
(862). For some models the coupling shells are
delivered separately.
2. Thoroughly clean the motor stool (341), the shaft (210),
the coupling shells (862) and the motor shaft.
3. Loosely fasten the coupling shells (862) with the
coupling pin (560) on the shaft (210). Use the hexagon
socket head cap screw (914.01) and the nut (920.01)
for this purpose. (When the pump is equipped with a
steel coupling, never use the same coupling twice but
order a new one).
4. Place the motor on the motor stool (341).
5. Tighten the lower bolts of the coupling shells (862)
so far that the coupling slightly clamps around the
motor shaft.
6. Lift the pump assembly to the maximum upwards
position put a tyre lever under the coupling.
ATTENTION
For motors of 15HP or higher, block the
rotor when adjustments are made to
the coupling. This ensures that the rotor will
not come out of its bearings.
IMPORTANT
Correct seal tension max, -1mm lower than
the maximum upwards position!
7. Position the pump assembly 1mm lower than the
maximum upwards position as mentioned earlier.
8. Fully tighten the couplings to the correct torque (See
“Torques” in the annexes). Make sure that the gaps
between the couplings are equally divided on both
sides (see drawing).
9. Attach the coupling guards (681) with the hexagon
head bolts (901.01) to the motor stool (341).
10. Connect the electricity supply to the motor.

11
F-2.2) Installing the motor on pumps, supplied without
motor, with a cartridge seal:
1. Remove the “transport fixation assembly” together
with the coupling guards (681) and the coupling shells
(862). For some models the coupling shells are
delivered separately.
2. Thoroughly clean the motor stool (341), shaft (210),
coupling shells (862) and the motor shaft.
3. Loosely fasten the coupling shells (862) with the
coupling pin (560) on the shaft (210). Use the hexagon
socket head cap screw (914.01) and the nut (920.01)
for this purpose. (When the pump is equipped with a
steel coupling, never use the same coupling twice but
order a new one).
4. Place the motor on the motor stool (341).
5. Loosen the three cartridge grub screws (904) one turn.
6. Push the hydraulic pump assembly in the lowest
position.
7. Tighten the three cartridge bolts (904) firmly to the shaft.
8. Tighten the lower bolts of the coupling shells (862) so
that the coupling clamps slightly around the motor shaft.
9. Lift the pump assembly to the maximum upwards
position and mark the shaft. For this purpose put a tyre
lever under the coupling
ATTENTION
For motors of 15HP or higher, block the rotor
when adjustments are made to the coupling.
This ensures that the rotor will not come out
of its bearings.
IMPORTANT
Correct seal tension max. -1mm lower than
the maximum upwards position!
10. Position the pump assembly 1mm lower than the
maximum upwards position as mentioned earlier.
11. Fully tighten the couplings to the correct torque (see
“Torques” in the annexes). Make sure that the gaps
between the couplings are equally divided on both
sides (see drawing).

off valve (B).
2. Open the fill plug (C).
3. Gradually open the suction shut-off valve until the liquid
flows from the fill plug (C).
4. Close the fill plug.
5. Fully open the suction shut-off valve.
6. Check the rotational direction of the pump.
7. Fully open the outlet shut-off valve.
F-4.2) In an open circuit with a liquid level lower than
the pump:
1. Partly loosen the drain lug (A). For BPVE, BPVCF, and
BPLHS the drain plug must be fully removed.
2. Remove the fill plug (B) from the top bracket.
3. Block the entry of the drain plug on the outside of the
pump foot.
4. Close the outlet shut-off valve.
5. Fill the pump housing to the maximum through the fill
plug with the liquid that is to be pumped.
6. Screw the drain plug into the pump foot.
7. Insert the fill plug in the top bracket.
8. Check the rotational direction of the pump.
9. Open the outlet shut-off valve.
F-4.3) After an extended period of non-operation or
storage:
During first start-up, be sure to check the mechanical seals
for leakage due to seizure or dehydration of he lubricating
film. if this is the case, please proceed as follows:
1. Turn shaft manually or;
2. Start up the pump, then open and close the outlet shut-
off valve quickly during operation.
3. Check if the mechanical seal is still leaking.
If the shaft is still leaking:
1. Disassemble the mechanical seal.
2. Thoroughly clean and degrees the running surfaces.
3. Assemble the mechanical seal again ad retry start-up.
If this doesn’t solve the shaft leakage, replacement of the
mechanical seal is necessary.

Problem Possible Cause Possible Solution Checkpoints
Pump supplies
insufficient capacity and/
or pressure
Outlet and/or inlet shut-off valve
is closed
Open both shut-off valves
There is air in the pump Vent the pump
The suction pressure is insufficient Increase the suction pressure
Pump rotates in the wrong
direction
Change over L1 and L2 of the
three phase supply
The suction line has not been
vented
Vent the suction line
Air bubble in the suction line Install the suction line with pump
end higher than the other end
Pump sucks air because of
leakage in the suction line
Repair the leakage
Too little water consumption so air
bubbles clog up in the pump
Make sure the consumption
increases or use a smaller pump
The diameter of the suction line is
too small
Increase the diameter of the
suction line
Capacity of water meter in the
supply line is too small
Increase the capacity of the water
meter
Foot valve blocked Clean the foot valve
The impeller or the diffuser is
blocked
Clean the inside of the pump
O-ring between impeller and
diffuser is gone
Replace the O-rings
O-ring not resistant to the medium
to be pumped
Replace O-ring by an O-ring with
better resistance

These instructions concern the repairs which can be
handled by a local service engineer. Please note that
during all mentioned repairs all precautions are to be taken
and the pump always has to be disconnected from the
electrical supply. The numbers mentioned after the parts
refer to the position numbers of these parts in the cut
away drawing of the pump concerned.
IMPORTANT
Never allow the pump to run dry
M-2) Replacement of standard mechanical seal
BPV(S):
1. Check if pump is drained and if not, drain it.
2. Remove the hexagon head bolts and coupling guards
(901.01, 681), disassemble the coupling shell (862) and
the pin (560), unscrew hexagon head bolts and washer
(901.02, 554.02) and take the motor (800) off the motor
stool (341).
3. Loosen the 4 nuts (920.03) crosswise and equally lift
the motor stool (341) and the cover (160) from
the upper stage casing (108.05/108.06/171.03) and
the pump-shroud (10-6). If necessary use a screwdriver
(flat and narrow) to remove the motor stool (341) from
the pump-shroud (10-6). Push the screwdriver in the
groove of the pump-shroud (10-6) and rotate it around
the edge of the motor stool (341). Repeat this action
several times until the two parts are separated.
4. Pull the rotating part of the mechanical seal (433)
from the shaft (210). Clean the shaft (210) and check
for damages.
5. Wet the shaft-end (210) with water or a soap solution.
Push the rotating part of the new mechanical seal (433)
on the shaft (210).
6. Remove the old static part of the mechanical seal (433)
from the cover (160) assembly. Wet the new part of the
mechanical seal (433) with water or a soap solution and
put it in the motor stool (341). Slide this cover (160) into
the motor stool (341) and over the mechanical seal.
7. Finish the pump assembly as described in xx.xx.x
Finishing the pump assembly all BPV(S)(C)(F) with
standard mechanical seal 195.
8. Install the motor (800) on the motor stool (341) and
assemble pin (560) and coupling shell (862) on the
shaft (210) as described in xx.xx.x BPV(S)(F)
2/4/10/18/32/45/65 with standard mechanical
seal 196.
9. De-aerate pump and pipe work. Check for the correct
rotation (clockwise). See xx.x Setting up the pump 145.
10. Test run the pump and retighten the tie-rods crosswire
and equally on torque.
M-3) Replacement of standard mechanical cartridge
seal BPV(S)F 32/45/65:
1. Carefully relieve any pressure in the pump.
2. Remove hexagon head bolts (901.01) and coupling
guard (681), disassemble the coupling shell (862) and
the pin (560)
3. Unscrew the three grub screws (904) partly and the four
hexagon socket head cap screws (914.01) completely.
4. Place a screwdriver between the seal cover (471) and
the motor stool (341) and lift the cartridge seal from the
shaft (210)
5. Unscrew the grub screws (904) completely and remove
the ring (500), if present the flat ring and the seal cover
(471), from the spacer sleeve cartridge (525.07).
6. Remove the old static part of the mechanical seal (433)
from the seal cover (471) with water or a soap solution
and place the new static part.
7. Remove the old rotating part of the mechanical seal
(433) from the spacer sleeve cartridge (525.07).
Clean the spacer sleeve cartridge (525.07) and check
for damages.
8. Wet the spacer sleeve cartridge (525.07) with water or
a soap solution and place the new rotating part.
9. Remove the O-rings (412.05, 412.06) from the spacer
sleeve cartridge (525.07) and the seal cover (471) and
replace them by new ones.
10. Slide the seal cover (471) on the spacer sleeve
cartridge (525.07) and the ring (500) and screw grub
screws (904) partly in. Do not replace the flat ring.
11. Wet the shaft (210) with water or a soap solution and
place the new cartridge seal.
12. Assemble pin (560) and coupling shells (862) on the
shaft (210) as described in xx.xx.x BPV(S)F
32/45/65 with mechanical cartridge seal 197.
