The Grundfos SQ series of submersible well pumps with motors are available for 3” maximum diameter wells. This series is extremely compact and ideal for small or restricted boreholes that are no larger than the pump itself.  The SQ offers a number of motor protection and wear-reducing features. The SQ motor is protected against over and under voltage and voltage fluctuation generally.

Includes

• Check valve

Features

• Soft start ensures a low current with a smooth and steady acceleration, offering excellent starting reliability at low voltage, prevents overload of the mains power, reduces water hammer in the pipe and reduces pump wear
• Low current draw and soft start allows use of smaller gauge wire compared to traditional 4” motors, this can reduce the overall cost of installation
• Low ampere usage makes it possible to connect more appliances to the same fuse group or reduce the size of the power line
• It is recommend to use a generator with a capacity 50% higher than rated pump power consumption
• Factory pre-set based on minimum power consumption and dry running protection is activated 40 seconds after power is connected to allow priming of the pump
• Stainless steel materials are used on this pump to ensure durability
• The SQ pump can be installed vertically or horizontally
• Built in electronics
• Permanent magnet motors with high effiiency
• Protection against upthrust
• High flow velocity
• Torque exceeds that of traditional motors
• Higher efficiency than traditional motors
• Maximum acceptable media temperature is 86°F when flow past motor
• Over temperature protectin
• Overload protection
• Over and under voltage protection

Applications

• Groundwater extraction
• Domestic or small waterworks
• Small irrigation systems
• Groundwater lowering
• Pressure boosting
• Garages and petrol stations
• Liquid transfer in tanks
• Enviromental applications-remedial pumping or sampling
• Private housing
