4. Preparation

Before installation, the following checks should be made:
1. Transport damages
Make sure that the pump has not been damaged during
transportation.
2. Pump type
Check that the type designation corresponds to order, see
pump nameplate.
3. Electricity supply
Check that the supply voltage and frequency correspond to
the values stated on the motor nameplate and frequency
converter nameplate, if any.

5. Technical data

See motor and pump nameplates.

5.1 Sound pressure level

The table below indicates the sound pressure level in dB(A)
measured in a reverberation room at a distance of 1 metre from
the pump. The anechoic noise level is calculated by subtracting
3 dB(A) from the stated values.

6. Installation

The BMP pump can be used in both closed and open systems.
• The suction port is marked with an "I".
• The discharge port is marked with an "O".

6.1 Position of pump

Fig. 1 Position of pump
The pump must be installed on a solid foundation by means of the
bolt holes in the foot-mounted motor. It is recommended to use
vibration-absorbing machine feet.
