Protection against:
Dry running
Over voltage and under voltage
230 V cuts out at < 150 V and > 280 V
115 V cuts out at < 75 V and > 150 V
Overload
Over temperature
Sound pressure level The sound pressure level is < 74 db[A] at a distance of 3 feet (1 meter). It is recommended by
Grundfos that the pump be installed with sound and vibration dampening equipment such as;
flexible piping adapters and anti-vibration mounting. The pump should not be mounted in or
adjacent to living quarters. The pump can also be wrapped with sound proofing insulation to
reduce noise. (See page 16, EZ Boost System Diagram.)
Reset function BMQE pumps can be reset via EZ Boost controller.
Power factor PF = 1.
Operation via generator It is recommended that the generator output is equal to the motor input power P1 [kW] plus
50%; min. P1 +10%, however.
Pipe connection 1.25” NPT inlet / 1” NPT discharge.
Strainer Holes of the strainer: ø0.09” (2.3 mm)

System
EZ Boost Controller
The EZ Boost controller is a control and communication
unit especially developed for the BMQE booster pumps in
constant pressure applications.
The EZ Boost controller provides:
• Full control of the BMQE pumps
• Two-way communication with the BMQE pumps
• Possibility of adjusting the pressure
• Alarm indication (LED) when service is needed
• The possibility of starting, stopping and resetting the
pump simply by means of a push-button
The EZ Boost controller communicates with the pump via
power line communication, meaning that no extra cables
are required between the EZ Boost controller and the BMQE
pump.
The EZ Boost controller features the following indications
(see drawing below):
1. Flow indicator
2. System pressure setting
3. System ON/OFF
4. Button lock indicator
5. Dry-running indicator
6. Service needed in case of:
– No contact to pump
– Over voltage
– Under voltage
– Speed reduction
– Over temperature
– Overload
– Sensor defective
The EZ Boost controller incorporates external signal input
for pressure sensor and a pump status relay for use with
devises dependant on pump status.
