1.5 Intended Use and Remarks on Safety
The bare shaft set is exclusively designed for
supporting a Bredel pumphead and a drive. Every other
use is not in conformance with the intended use. Refer
to the manual of the pumphead for more information on
safety and the intended use of the complete pump.
ENVIRONMENT
Always observe the local rules and
regulations with respect to processing
(nonreusable) parts of the hose pump.
WARNING
Procedures which, if not carried out with
the necessary care, may result in serious
bodily harm.
CAUTION
Procedures which, if not carried out with
the necessary care, may result in serious
damage to the hose pump, the surrounding
area or the environment.
Remarks, suggestions and advice.

1.6 Warranty Conditions
Refer to the manual of the pumphead for warranty
conditions. These conditions are applicable to the bare
shaft set as well. Damaged parts of the bare shaft set
that are returned to the manufacturer must be
accompanied by a fully filled in and signed safety form
that can be found in the manual of the pumphead.

DESCRIPTION

2 DESCRIPTION
The bare shaft set, if delivered separately, consists of a
support set (B) and a bare shaft kit (A). These two
components are packed separately. If the set is
delivered in a complete pump with pumphead and drive
a flexible coupling (C) is included.
The support set consists of two frame halves, an
adjustable drive support plate and a coupling guard.
The bare shaft kit consists of a shaft, a hub, a bearing
and a seal. No fasteners are provided for mounting the
drive or gearbox.
To align the pump and the drive use alignment jigs. The
jigs are not included in the package.

3.1 Unpacking and Inspection
Follow the unpacking instructions on the packaging.
Check that your delivery is correct and does not have
transport damage. Report any damage immediately to
your Bredel representative.
This chapter will treat the installation of the bare shaft
set. Refer to the manual of the pumphead for
installation and setup of the complete pump and the
pipework.
3.2 Installation
Caution
The drive or gearbox and the pump must
be aligned within the misalignment limits of
the flexible coupling.
Carry out the alignment of the drive or
gearbox and the pump at the pump’s final
operating position. If the support set has to
be bolted to the floor this must be done
first.
A movement of the complete pump will
disturb the alignment due to elasticity of
the construction.
If the bare shaft set is delivered as part of a
complete pump, including pumphead and
drive, a realignment must be done at the
pump’s final operating position.

INSTALLATION

3.2.1 Mounting the support set and the bare shaft
kit to the pumphead
For mounting the kit to the pumphead, the pump must
not be part of a process line and must not contain
lubricant.
1. Use a hoist to place the pumphead (A) against
the support set (B).
2. Insert six sets of washers and bolts (C). Tighten
the bolts with the correct torque. See section
6.3.
Leave the coupling guard demounted.
3. Use a hoist to remove the cover of the
pumphead.
4. Place the O-ring (A) into the groove of hub (B).
5. Make sure the key is removed from the shaft
(C). Slide the shaft (C) into the rotor hub (D),
until the hub (B) is against the rotor.
6. Insert eight sets of washers and bolts (A).
Tighten the bolts with the correct torque. See
section 6.3.

7. Clean the contact surfaces (B) for the bearing
and the seal. Put some transmission oil on
these surfaces (B).
8. Place the retaining ring (C) in the groove (A) of
the shaft.
9. Apply an excessive amount of grease on the
seal (D).
10. Make sure that the hub (C) contains the seal,
the bearing and the outer retaining ring.
Slide the hub (C) over the shaft (B) until it is
against the hub (A).
11. Insert eight sets of washers and bolts (A).
12. Tighten the bolt or nuts in at least two crosswise
cycles. In the last cycle tighten them with the
correct torque. See section 6.3.

13. Place the key (A) in the shaft end. Loosen the
setscrew (B) from the coupling half.
14. Screw a threaded rod (E) into the shaft end.
Place the coupling half (C) on the shaft end.
Install a disc (D) and nut (F) on the threaded rod
(E). Turn the nut (F) to drive the coupling half
(C) onto the shaft.
15. Fasten the setscrew (B) in the coupling half (C).
16. At the front of the pumphead check if the shaft
in still correctly positioned in the flange. Place
the pump cover. Insert the washers and bolts.
Tighten the bolts in at least two crosswise
cycles. In the last cycle tighten them with the
correct torque. See section 6.3.

3.2.2 Mounting and aligning the Drive
1. Determine the correct height of the centre of the
bare shaft according to the surface on which the
drive will be mounted. The bare shaft height
must correspond with the height of the output
shaft centre (of the drive that will be mounted).
2. To correct the height loosen the 12 sets of
fasteners (A).
Move plate (B) up or down to the correct
position and slightly tighten the fasteners (A).
Check the height and repeat this step if
necessary.
If the height is correct, tighten the fasteners (A)
with the correct torque. See section 6.3.
Use a hoist to lift the heavy drive.
Mounting and aligning the drive must be
done on the pump’s final operation
position. Moving the complete pump
assembly after alignment will require re-
alignment at the pump’s final operation
position.

3. Place coupling half (B) on the output shaft of the
drive and slightly fasten screw (C).
Make sure the shaft end has been shifted far
enough into the coupling half but will not
penetrate into the coupling spider (A).
4. Use a hoist to place the drive on the support
set.
5. Make sure spider (A) is placed in one of the
coupling halves.
6. Slide the drive toward the pumphead.
Make sure that the coupling halves (A) and the
spider mesh correctly.
7. Use two alignment jigs (D) to check the
alignment of the coupling halves in the vertical
plane. Looking from aside both coupling halves
(C) must touch the horizontal edge of the upper
jig.
If necessary loosen the fasteners (A), readjust
plate (B) and tighten the fasteners (A) to
accomplish this. Use a hoist to lift the drive.
Axial, radial and angular displacement of the
coupling halves must be minimised.
8. Each side plate of the support set has two pre-
drilled holes (A).
Drill each hole through both plates.

9. Drive a pin (A) into each drilled hole to fix the
horizontal plate in the support set side plates.
10. Use two alignment jigs (D) to check the
alignment of the coupling halves in the
horizontal plane. Looking from above both
coupling halves (C) must touch the edge of both
jigs.
If necessary move the drive (E) over the plate
(B) to accomplish this.
Axial, radial and angular displacement of the
coupling halves must be minimised.
11. Mark the holes (A) for fixing the drive on the
plate of the support set using a punch and a
hammer, or a felt-tip pen.
12. Remove the alignment jigs and use a hoist to
remove the drive.
13. Drill holes, with the correct diameter, in the
horizontal plate (B) at the marked places. See
section 6.3.
14. Remount the drive and slide it toward the
pumphead so that the coupling halves mesh.
15. Fix the drive to the horizontal plate with
fasteners (C) (washers, bolts and nuts). Do not
tighten the fasteners yet.
16. Repeat step 10. (alignment in a horizontal
plane)
Tighten the fasteners (C) and the screws of the
coupling halves with the correct torque. See
section 6.3.
17. Place the coupling guard (A).
Tighten the fasteners (B) with the correct
torque. See section 6.3.

4.1 Cleaning
4.2 Demounting the pumphead
1. Isolate the drive from the electrical supply.
Close any shut-off valves in the suction and
discharge lines and disconnect these lines.
Refer to the manual of the pump.
2. Loosen the fasteners (A) of the coupling guard
and remove the coupling guard (B).
Warning
When cleaning the pump do not use a
high-pressure spraying pistol. This might
damage the seal and the bearing.

be done in two ways: demounting the
pumphead from the support set or
demounting the drive from the support set.
