BM 3A-9N NBR

BM 3A-9N NBR
BM is an encapsulated submersible pump that is suitable for applications where a high pressure is required. Therefore, BM is ideal for water treatment, liquid transfer, pressure boosting and closed circulation systems with a high static pressure.

BM pumps are available in four different versions (standard, N-version, NE-version, and R-version), in various sizes, and with a large variety in the number of impellers. The range covers BM 3A to BM 215, a total of twelve sizes. Depending on its size and frequency, a BM pump can reach a flow rate of 265 or 310 m3/h. BM pumps can increase the system pressure up to 82.7 bar.

The pump is supplied with an asynchronous motor, Victaulic connections, a straight or 90° bent pipe for BM 3A, BM 5A and BM 9 pumps and a straight pipe for BM 18 and above. The motor is protected by output filters against overvoltage and increased operating temperature. As a result, BM is very reliable and durable. The compact design ensures easy maintenance and alignment of the pump.

The stainless-steel pump and motor housing ensure an excellent resistance against different types of liquids. The R-version is designed to be highly efficient against corrosive liquids.

Three different types of asynchronous motors are available for BM pumps: MS 4000, MS 6000 and MMS 8000.
The enclosure class is IP68. The motor power ranges from 0.75 to 92 kW. The motor is controlled by a frequency converter and protected by Pt100 sensors. The frequency converter is sold as a separate accessory and must be purchased along with the pump. We recommend a Grundfos CUE frequency converter; however, frequency converters from alternative suppliers can be used as well.
