MQ3-45 A-O-A-BVBP

Complete system The MQ is a complete, all-in-one unit, incorporating pump, motor, diaphragm tank, pressure and flow sensor, controller and non-return valve. The controller ensures that the pump starts automatically when water is consumed and stops automatically when the consumption ceases. In addition, the controller protects the pump in case of faults.

Installation Due to its space-efficient design, the pump does not take up much space and is straightforward to install. No space around the pump is required.

uncomplicated operation The pump features a user-friendly control panel with ON/OFF button and indicator lights for indication of the operational state of the pump.

Self-priming pump As it is self-priming, the MQ is able to pump water from a level below the pump. Provided it is filled with water, the pump is able to lift water from a depth of 8 m in less than 5 minutes. This facilitates installation and start-up of the pump and provides more dependable water supply in installations where there is a risk of dry running and leakages in suction hose or pipes.

Built-in protective functions If exposed to dry running or excessive temperature, for example in case of seizure or overload, the pump will stop automatically, thus preventing a motor burnout.

self-operating reset The pump features an self-operating reset function. In case of dry running or similar alarm, the pump will stop. Restarting will be attempted every 30 minutes for a period of 24 hours. The reset function can be deactivated.

Low noise level Thanks to its hydraulic design and internal cooling, the pump is extremely low-noise, which makes it appropriate for indoor as well as outdoor use.

Pressure tank The built-in pressure tank reduces the number of starts and stops in case of leakages in the pipe system, causing less wear on the pump.

Maintenance No maintenance of the pump is required.

Suitable for: Domestic water pressure boosting

CMBE 1-44 I-U-C-D-D-A

The Grundfos CMBE booster is a space-efficient booster system for water supply in domestic applications. The integrated speed controller enables the CMBE booster to keep constant pressure in the pipe system. A pressure sensor monitoring changes in the water consumption signals the speed controller to change motor speed to adapt performance to the new state. The CMBE booster is very straightforward to install. When the system has been connected to the pipes, it is only a matter of inserting the power plug into a power outlet, and the system is operational. The CMBE booster consists of the following:

The Grundfos CMBE booster requires no external motor protection. The MGE motor incorporates thermal protection against slow overloading and blocking (IEC 34.11: TP 211).

The Grundfos CMBE booster is mainly used for domestic and light commercial water supply or booster systems.

Suitable for: Domestic rainwater harvesting
