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.
