FeaturesSelf-primingWith a suction lift of up to 8 metres (self-priming up to
4 metres), the CM Booster Self-Priming is ideal for pressurising
water from above or below ground water sources.
Robust designAll wetted parts are made from high quality, corrosion
resistant stainless steel to ensure the longest life possible.
User-friendly interfaceThe pump features a user-friendly interface with LED
indicators displaying power status, pump running, alarm
indication and pressure indication (excluding CMB-SP 1-36).
Protective featuresThe pump incorporates a range of protective features such as;
dry run protection, thermal overload protection, cycling alarm
and maximum continuous operation time - 30 mins (excluding
CMB-SP 1-36) to protect the pump and ensure a long life.
Easy installationThe booster unit is a compact and adaptable solution, which
makes it suitable for most installations. Simply connect the
inlet and outlet and adjust the start pressure to suit individual
requirements and you have a fully operational booster unit.
Integrated non-return valveNon-return valve for backflow prevention.
The Grundfos CM Booster Self-Priming is a compact booster pump designed for domestic and light industrial use. The booster unit consists of a robust multistage centrifugal pump and a generator friendly PM1 or PM2 Pressure Manager. The Pressure Manager allows the pump to start and stop automatically according to demand and protects the pump from dry running. The CM Booster Self-Priming is the perfect solution if you are struggling with insufficient mains pressure, and can also be used with above or below ground water sources.
CM Booster Self-Priming
Applications - Mains boosting- Household water supply- Boosting from above ground water tanks- Boosting from below ground water sources e.g. below ground tank/dam- Light industrial use

How tHe SQ(e) protectS and reduceS wear
VolTAGE hAndlInG
Increased winding temperature caused by under voltage often reduces the lifespan of the pump. The SQ(E) motor is protected against voltage fluctuations including over and under voltage.
dry runnInG ProTEcTIon
The SQ(E) pump is factory pre-set based on minimum power consumption. Dry-running protection is activated 40 seconds after power is connected to allow priming of the pump. When there is no water in the hydraulics, power consumption is reduced. The SQ(E) stops automatically when below the dry run power limit and restarts automatically within 5 minutes after cut-out.
SQe and cu301conSTAnT PrESSurE oPErATIon
When using a CU301 controller with the SQE pump, water pressure will always remain constant regardless of how much water is being consumed. As more taps are opened, the pump automatically increases its speed, maintaining the chosen pressure at any flow rate.
PowEr lInE communIcATIon
The SQE communicates with the CU301 without the need for additional cables. If there is a failure at the pump, via the power cable, simple diagnostics can take place.
SImPlE ProGrAmmInG
The CU301 has a simple interface with up/down buttons to control the pressure of the pump. Hold both the up and down buttons for 5 seconds and the unit is locked - easy.
SofT STArT
Soft start ensures a low starting current with a smooth and steady acceleration. This offers excellent starting reliability at low voltage, prevents overload of the mains power, reduces water hammer in the pipe and reduces pump wear.
for morE InformATIon conTAcT:
PowEr SuPPly
Low ampere usage makes it possible to connect more appliances to the same fuse group or reduce the size of the power line. Small generators can be used with SQ(E).
Grundfos recommends to use a generator with a capacity 50% higher than rated pump power consumption.
The SQ(E) pump provides several features that simplify your installation and add reliability to the system.
