2. SAFETY AND ENVIRONMENT:
2.1 General safety instructions
- Only trained and authorized staff may install, and maintain the pump
after carefully reading this manual.
- Only use the pump for its intended purpose and under the regulated
circumstances.
- Don’t go near rotating parts.
- Clean the pump before maintenance and inspection.
- Observe the local regulations when working with aggressive, corrosive, toxic,
flammable and explosive chemicals.
- Never remove safety signs, keep them clean.
- Always connect to a grounded circuit.
- Before maintenance and inspection always disconnect the pump from the
mains.
- Use a proper hoist for lifting and handling the pump.
- Never drop the loose cable end in water.
2.2 Environment
Parts which will be replaced during repair, maintenance or renewal, could contain
materials which could be harmful to the environment.
Please be also aware that some of the components can be very useful for reuse.
The owner is responsible for careful disposal and processing of the materials.
Do this in according to the local environmental regulations.

3. TECHNICAL DATA:
3.1 General:
The BTP pump is cast iron closed spiral vane impeller pump, designed to pump sewage and
other solids containing waste water with low energy consumption.
The impeller is designed in such a way that fibrous materials will not hook onto the edge but slide
along towards the impeller passage.
3.2 Construction:
Two independent shaft seals, running in oil.
Heavy duty bearings, greased for life.
closed spiral vane impeller for low energy consumption.
Vanes at the backside prevent solids entering the seal area and reducing the pressure on the
seal.

3.4 Sound level:
Depending on duty point and speed, the pump will produce a certain sound level.
Next to this the piping system may produce some noise and vibration.
By altering the pipe support and using rubber compensators the vibration will be reduced.
In the next table the sound levels of the BTP pumps are shown.
4. CHECK POINTS BEFORE INSTALLATION:
After unpacking the pump, follow out the following check points:
4.1 Delivery-check:
Check for possible transport damage.
Check for complete delivery.
When the delivery is incomplete or damaged, please contact your dealer immediately.
4.2 Oil level:
Check the oil level in the oil tank.
The oil plug has a gauge rod and the level should be between the two indications.
4.3 Power supply:
Before making the electrical connections, check if the line voltage and frequency are
the same as on the pump data-plate.
If thermostats are supplied make sure that they are correctly connected.
For examples of electrical diagrams and pump cable coding, see appendix 1 and 2.

4.4 Motor protection:
The pump should always be connected to the line by means of a suitable motor
protection circuit breaker.
If the pump is started direct on line (DOL), the protection breaker should be set to the current, as
given on the data-plate.
For star delta start (YD), it is preferable to install the over current relay directly after the
main contact. In this case, the pump is also adequately protected in star-connection.
The maximum setting of the over current relay is 0.6 x the current as given on the data
plate.
It is preferable also to set the protection breaker at a 10% lower current, because all breakers
require at least 110% of the adjusted current before tripping.
4.5 Motor check:
If you in doubt about the condition of the motor, “Megger”test motor windings against grounding
wire.
The value should be at least 1 M-Ohm.
4.6 Pump seals:
Turn the impeller clockwise by hand, using a proper socket wrench.
Following this procedure sticking mechanical seal surfaces will be loosened smoothly.
4.7 Installation:
Check if all components for your installation are delivered. See also chapter 6.

5. FIRST PUMP START:
5.1 Direction of rotation:
A correct direction of rotation is essential for proper operation.
Check the direction of rotation with the arrow on the pump-casing.
This can be done by observing the direction of rotation of the motor or coupling.
5.2 Current-check:
The current must be checked during normal operation.
Apply an ammeter to one of the phase wires and check if the current is not higher than
the value stated on the motor data-plate. If this is the case, check for:
- low voltage ?
- Specific gravity or viscosity too high ?
- blocked volute ?
- direction of rotation correct ?
If the problem cannot be solved contact your dealer or the manufacturer service department .
5.3 Start frequency:
When the pump is controlled by level regulation, the on and off levels should be
adjusted in such a way that the pump does not make more than 20 starts per hour.

6. INSTALLATION OPTIONS:
6.1 General:
For the BTP pumps the following installations are possible:
- Installation -H Horizontal, on base plate
- Installation -R Horizontal, on rail construction
- Installation -V Vertical, on support
- Installation -K V-belt driven
6.2 Installation - H:
Horizontal installation on base plate.
Checkpoints before operation:
- Fixation of the base-plate to the floor.
- Flanges straight horizontal and vertical
see fig. pos 1.
- Pump and motor shaft aligned,
see 6.2.1.
- Maximum flange forces and moments,
see 6.5.
- Adjust start and stop levels in such a way
that the pump does not make more than 20
starts per hour.
6.2.1Alignment of pump and motor shaft:
After the base-plate is fixed to the floor, the alignment of pump and motor-shaft must be checked.
When the base-plate is fixed to the floor, forces on the base-plate might have disturbed the
alignment . - Remove the protection hood, (pos 4).
- Check for:
- 1 radial deflection (R) max. 0.4mm.
- 2 angular deflection (A) max. 1o
To improve the alignment, use skims underneath the motor and pump fixing bolts.
Re-install the protection hood in the original position.
The main parts are:
1.
pump unit;
2.
bearing unit;
3.
flexible spacer coupling;
4.
protection hood
5.
electric motor;
6.
base plate;
7.

6.3.Installation R-
The main parts are:
1. Pump housing unit
2. Bearing housing (RF only)
3. Coupling
4. Lantern house
5. Motor
6. Slide construction
7. Fixing bolts
8. Pump housing foot
9. Discharge flange
10. Suction flange
11. Base plate with rail
construction
12. Sled Anchoring
13. Rail adjustment
When installing, it must be ensured that:
- The base plate (pos.11) is anchored to the foundation (pos. 7).
- The top surface of the discharge flange is level, (pos.9).
- The base plate is filled with non-shrinking concrete
- The forces on the discharge and suction flanges do not exceed the values according to the table
in section 6.6.
- The rails are adjusted accordingly with pos. 13 that it is level and that the pump can be smoothly
driven in and out of the pump housing. See par. 7.6.5
- The carriage anchoring pos.12 is adjusted in such a way that the wheels are not under tension
when the pump is not being serviced.
- The start and stop levels of the level control are set so that the pump does not make more than
20 starts per hour.
- If the base plate is connected to a subsequent base plate with rail construction, orientation must
be correct. The rails are properly oriented when the pin on the end of the rails falls into the hole
of the successive rails. The rails are symmetrical and can optionally be turned around on the
base plate. The rails can be adjusted with the aid of pos. 13 can be adjusted in all directions.
Adjust the rail construction and the coupled rails on the rail construction of the pump.
