• 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.
