BMQE PUMP

There are many applications within water supply where it is necessary to increase the system pressure. The Grundfos EZ Boost system is the optimum solution for applications requiring: • Sealless pumps • Quiet operation and/or • Maintenance-free operation. The EZ Boost system offers the following features: • Dry-running protection • High efficiency of pump and motor • Excellent wear resistance • Soft starter • Over voltage and under voltage protection • Overload protection • Over temperature protection. • Variable speed • Electronic control and communication. Applications • Pressure boosting. • Water treatment. BMQE Pump The pumps used for The Grundfos EZ Boost system are modified SQE submersible pumps. The EZ Boost BMQE pump is an SQE pump with an MSE 3 motor. Pump and motor are centered in the 4” stainless steel sleeve. BMQE pumps are suitable for both continuous and intermittent operation for a variety of pressure boosting applications. BMQE Motor The MSE 3 motors are based on state-of-the-art technology within permanent magnets (PM motor), which accounts for the high motor efficiencies. In addition, the motors have a built-in electronic unit with a frequency converter for variable frequency and soft starting. The MSE 3 motors features high efficiency within a wide load range. The high and flat efficiency curve of the PM motor enables the same motor to cover a wide power range as opposed to conventional AC motors. For BMQE pumps, this means fewer motor variants. EZ Boost Controller The BMQE pump features variable speed which is offered through frequency control via the EZ Boost controller. As a consequence, the pump can be set to operate in any duty point in the range between the minimum and maximum performance curves of the pump. Each BMQE pump must be connected to its own EZ Boost controller. It is also possible to operate the BMQE without an EZ Boost controller, though the features offered will be fewer.
