Grundfos BM hp 77-5-R NBR (96293291)
BM hp is an encapsulated submersible pump that is suitable for applications where a high system pressure is required, as it can handle an inlet pressure up to 80 bar. Therefore, BM hp is ideal for water treatment, liquid transfer, pressure boosting and closed circulation systems with a high static pressure.
BM hp pumps are available in R-version, in various sizes and with a large variety in the number of impellers. The range covers BM hp 18 to BM hp 215, a total of nine sizes. Depending on its size and frequency, a BM hp 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 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 hp 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.
Two different types of asynchronous motors are available for BM hp pumps: MS 6000 and MMS 8000.
The enclosure class is IP68. The motor power ranges from 5.5 to 30 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.
