4.3 Operation of the pump
The heart of the pumphead consists of a specially constructed pump hose which lies
contorted against the inside of the pump housing. Both ends of the hose are connected to
the suction and discharge lines by means of a flange construction. A bearing-mounted rotor
with two facing pressing shoes is in the center of the pumphead.
In phase 1 the lower pressing shoe compressed the pump hose by the rotational movement
of the rotor, forcing the fluid through the hose. As soon as the pressing shoe has passed, the
hose recovers to its original shape due to the mechanical properties of the material.
In phase 2 the product is drawn into the hose by the (continuous) turning motion of the rotor.
In phase 3, the second pressing shoe will subsequently compress the pump hose. Due to the
continuous rotating movement of the rotor not only new product is sucked in, but also the
already present product is pressed out by the pressing shoe. When the first pressing shoe
runs from the pump hose, the second pressing shoe has already closed the pump hose and
the product is prevented from flowing back. This method of liquid displacement is also known
as the “positive displacement principle”.

12
4.4 Pump hose
4.4.1 General
The pump hose is made of special rubbers, reinforced with nylon cords and is constructed as
follows:
A. Outer extruded layer made of natural rubber
B. Nylon reinforcement layers
C. Inner extruded liner
The pump hose liner material should be chemically resistant with the product to be pumped.
Dependent on the specific requirements of your application a corresponding pump hose must
be selected. For each pump model various hose types are available.
The material of the inner liner of the pump hose determines the hose type. Each hose type is
marked by a unique colour code.
Hose type Material Colour code
NR Natural rubber Purple
NBR Perbunan Yellow
EPDM EPDM Red
CSM Hypalon©Blue
Consult your Bredel representative for more detailed information about the
chemical and temperature resistance of pump hoses.
The Bredel pump hoses have been carefully machined, therefore there are minimum
tolerances in wall thickness. It is very important to guarantee the correct compression of the
pump hose, because:
•When the compression is too high, it creates a too high load of the pump and pump
hose, which will result in a reduction of the life of the pump hose and bearings.
•When the compression is too low, this will result in loss of capacity and backflow.
Backflow results in a reduction of the life of the pump hose.
4.4.2 Hose compression force adjustment (shimming). (not applicable for series SP/10,
SP/15 and SP/20).
In order to achieve optimal life of the pump hose, the compression force of the pump hose
can be adjusted by placing a number of shims under the pressing shoes.
The shims are fitted between the rotor and the pressing shoe. The number of shims will vary
for each counter-pressure situation. See “Hose compression force adjustment” § 7.8 and
“Shimming table” §10.1.7. Caution: insufficient shimming reduces hose life.
4.4.3 Lubrication and cooling
The pumphead, in which the rotor and pump hose can be found are filled with a special
lubricant.The lubricant lubricates the movement between the hose and the pressing shoes
and transfers the generated heat from the hose to the pump housing and the cover.
4.4.4 Gearbox
The hose pump types described in this manual use various types of gearbox units. The
gearboxes are fitted with a foot rest.

13
4.4.5 Electric motor
The hose pump type described in this manual use various types of motors. If the pump is to
be used in potentially explosive atmospheres, please contact your Bredel representative, as
these type of pumps are not in compliance with ATEX.
4.4.6 Available options
The following options are available for the hose pump:
•High (lubricant) level float switch
•Low (lubricant) level float switch (not applicable for SP/10, SP/15 and SP/20)
•Epoxy pressing shoes (not applicable for SP/10, SP/15 and SP/20)
•Stainless steel 316 flanges, flange brackets, hose clamps, supporting and mounting
articles

5 INSTALLATION
5.1 Unpacking
When unpacking carefully follow the instructions as given on the packaging or on the hose
pump.
5.2 Inspections
Check that your delivery is correct and check it for any transport damage, see “Description:
“Identification of the product”, § 4.1. Report any damage immediately to your Bredel
representative.
5.3 Installation conditions
5.3.1 Ambient conditions
Make sure that the hose pump is in an area where the ambient temperature during operation
is not lower than –20° and not higher than +45°C.
5.3.2 Set-up
•The pump materials and protective layers are suitable for indoor set-up and a
protected outdoor set-up. Under certain conditions the pump is suitable for limited
outdoor set-up or a salty or aggressive atmosphere. Consult your Bredel
representative for more information.
•Make sure that the floor surface is horizontal and has a maximum slope of 1 mm per
meter.
•Make sure that there is sufficient room around the pump to carry out the necessary
maintenance activities.
•Make sure that the room is sufficiently ventilated, so that the heat developed by the
pump and drive can be discharged. Keep some distance between the ventilation
cover of the electric motor and wall to enable the supply of necessary cooling air.
5.3.3 Pipework
When determining and connecting suction and discharge lines consider the following points:
•The bore size of the suction line must be larger than the bore size of the pump hose.
The bore size of the discharge line must be minimal or larger than the bore size of the
pump hose. For more information consult your Bredel representative.
•Limit the presence of sharp bends. Make sure that the radius of the bends are as
large as possible (preferably 5S). It is recommended to use Y-connections instead of
T-connections.
•It is recommended to use a minimum of three quarter (3/4) of the hose length as
flexible hose in the suction or discharge line. In this way you prevent that connection
lines must be removed when changing a pump hose.
•Keep the delivery and suction lines as short and direct as possible.
•Prevent any possibilities of exceeding the maximum working pressure of the hose
pump, see “Specifications”: “Performance”, § 10.1.1. If necessary fit an overpressure
valve.

15
CAUTION
Consider the maximum permissible working pressure on the discharge side.
Exceeding the maximum working pressure may lead to serious damage to the pump.
•Make sure that the maximum forces on the flanges are not exceeded. The maximum
permissible loads on the pump flange are given in the table below:
5.3.4 Pulsating flow
Hose pumps have a pulsating flow that can result in vibrations of pump and lines under the
following circumstances:
•suction and discharge lines are not fixed correctly
•high pump speed in combination with long suction and discharge lines or high specific
gravity of the product
•diameter of suction and/or discharge line too small
In case of unacceptable pulsations, dampeners for suction and/or discharge line can be
supplied for the pump series SP/25 to SP/100. Please consult your Bredel representative for
literature on Inlet Pulsation Accumulators (IPA) or Pulsation Dampeners (PD). These
accumulators and dampeners are not available for SP/10, SP15 and SP/20.
5.3.5 Pumping pressure (counter pressure)
Should not go over maximum allowance (7,5 bar for SP/10, SP/15 and SP/20; 16 bar for
bigger models). If hose failure looks like explosion, check system for blocked lines, closed
valves or failing pressure relief valves.
5.4 Lifting and moving the pump
For lifting and moving the pumphead, it has been fitted with a lifting strip. This lifting strip is
fitted on the rear of the pumphead. For the weights of the pump, see “Specifications”:
“Weights”, § 10.1.5.
The complete hose pump, i.e. pumphead, gearbox and electric motor, must be lifted using
the lifting eyes in the pump support plus additional support on gearbox and motor using
suitably rated straps or slings, see “Specifications”: Weights, § 10.1.5.

7.2 Cleaning pump hose
With a lot of products it is necessary to have the pump hose cleaned immediately after
pumping to avoid hardening of the product inside. The inside of the pump hose can be easily
cleaned by rinsing the pump with clean water. If a cleaning fluid is added to the water, it must
be checked that the hose liner material is resistant to that. Also note that the pump hose can
resist the cleaning temperature. Special cleaning balls are also available; please consult your
Bredel representative).
7.3 Changing lubricant
•Place a tray under the drain plug (series SP/25 to SP/100) in the cover of the pump.
Remove the drain plug. Catch the lubricant from the pump housing in the tray.
Position the drain plug and tighten it firmly. In case of SP/10, SP/15 and SP/20
pumps: remove the hose and drain via the lower port.
•The pump housing can be filled with lubricant via the breather/vent on the cover. For
this purpose remove the breather cap and position a funnel in the breather. In order
to facilitate the filling with lubricant for the series SP/25 to SP/100 it is advised to
remove one or two bolts in the inspection window. Pour the lubricant in the pump
housing via the funnel.
•Keep on pouring until the lubricant level has risen at approx. half way of the pump
casing, or that the specified quantity has been filled. See “Lubricant” § 10.1.3.
7.4 Changing oil in gearbox
For information regarding the changing of oil in the gearbox and the type of oil to be used we
refer to the documentation of the manufacturer of this item.
7.5 Replacing pump hose
7.5.1 Hose removal
The pump hose can be changed without removing the pump cover. If applicable, close the
isolation valves on both the inlet and discharge of the pump to minimize fluid loss.
7.5.2 Removal of lubricant
Place a lubricant tray of sufficient capacity to contain the hose lubricant plus any process
fluid that might be contained within the pump housing. Remove the drain plug (not applicable
for SP/10, SP/15 and SP/20; lubricant will flow when hose is removed) . Ensure that the
breather vent in front is not blocked.
7.5.3 Removal of piping
Shut off the valves on both suction and discharge side and disconnect the piping of both the
ports.
7.5.4 Loosening of hose clamps
Loosen all hose clamps on both suction and discharge ports.
7.5.5 Removal of flanges and/or inserts
Pull the inserts from the hose (SP/10, SP/15 and SP/20) by removing the flanges (SP/25-
SP/100) on both the suction and discharge port.

20
7.5.6 Removal of flange brackets
Remove the flange bracket (SP/25-SP/100) or flange bracket and insert (SP/10, SP/15 and
SP/20) on both suction and discharge port.
7.5.7 Removal of the hose
The hose can be removed without removing the pump cover.
Simply remove the hose by jogging the drive motor.
7.5.8 Cleaning of pump casing
Flush out casing cavity to remove any contaminants. If necessary remove the pump cover to
clean casing completely (but isolate the pump from the electrical supply first).
WARNING
Never remove the pump cover whilst the hose is in place.
The front covers of the series SP/25 to SP/100 should not be removed whilst
the hose is in place. This can cause a deformation of the pump casing and a
non straight tension of the bolts. After fitting the cover and starting up the
pump, the bolts can be extremely forced and break.
When the pump cover was removed for cleaning purposes, refit it before installing the
hose Check the cover O-ring for damage and replace if necessary. Make sure that the bolts
are refitted and that they are tightened in the correct order, diagonally opposite each other,
see “Specifications”: ‘’Torques’’, § 10.1.6.
7.5.9 Tighten drain plug (not applicable for SP/10, SP/15 and SP/20)
Before the hose can be loaded the drain plug has to be mounted. Make sure that the drain
plug is mounted in such a way that no leakage of lubricant can occur.
7.5.10 Preparation of pump hose
Clean the outside of the pump hose and thoroughly lubricate the external surface of the hose
with the Bredel hose lubricant.
7.5.11 Insertion of the hose
•Switch on the electrical supply again and insert the hose into the upper port.
•Jog the drive motor to feed the hose through the housing.
•If necessary, help by pressing the hose firmly into the port opening.
•Stop the drive when the hose is equally extended from the ports.
7.5.12 Place hose clamps
Place on both the suction and discharge port the bushes, all hose clamps (do not tighten
yet!), the brackets, the flanges and the inserts.
7.6 Hose connection
Note: Always start hose connection at one port and finalize these actions completely. Then
repeat these actions for the other port. In this instruction we start from the suction port.
