The Grundfos 10SQ05-160 is our most popular submersible well pump and for good reason - they are a perfect match for those using off-grid solar power systems!
Advantages
- Superior build quality - every Grundfos pump is manufactured using only high-quality stainless steel enclosures
- Simple 2-wire (2 wires ground) electrical connection
- 1/2HP, single phase, 60Hz, 3-stage motor
- 10 GPM, total dynamic head = 160FT
- Soft-start technology - unlike standard submersible pumps, soft-start technology means you can use a smaller inverter, and consume less power during operation
- 115vAC connection - We can't tell you how many times customers make the mistake of purchasing a deep well submersible pump that requires 240vAC and oversized for their needs! This is especially important because those who have smaller off-grid requirements are forced to invest in expensive 240vAC split-phase inverters who otherwise could be using smaller 120vAC inverters.
- UL Certified (for both US and Canada)
- 2-Year Warranty
The 10SQ05-160 can be installed without the need of any additional control units, and connect directly to a standard residential pressure switch pressure tank.

SQ innovative motor technology
SQ pumps feature an innovative motor design incorporating permanent-magnet technology. By combining permanent-magnet motors and a Grundfos micro-frequency converter, we are able to deliver unmatched performance and the ability to control and communicate with the pump in ways never before possible.
High pump efficiency
The hydraulic pump components are polyamide reinforced with 30 % glass fiber. The hydraulic design provides for high pump efficiency resulting in low energy consumption and therefore low energy costs.
High motor efficiency
The motors are based on a permanent magnet rotor (PM motor) featuring high efficiency within a wide load range.
Wear resistance
The pump design features "floating" impellers (not fastened to the shaft). Each impeller has its own tungsten carbide/ceramic bearing.
Protection against upthrust
Starting up a pump with a very low counter pressure involves the risk of the entire impeller stack being lifted, also called upthrust. Upthrust may cause breakdown of both pump and motor.
Excellent starting capabilities
The integrated electronic unit of the motor features soft starting. Soft start reduces the starting current and thus gives the pump a smooth and steady acceleration.
The soft starter minimizes the risk of wear on the pump and prevents overloading of the mains during start-up.
The excellent starting capabilities are a result of the high locked-rotor torque of the permanent magnet motor together with the few pump stages. The high starting reliability also applies in case of low voltage supply.
Overload protection
Exposure of the pump to heavy load causes the current consumption to rise. The motor will automatically compensate for this by reducing the speed to 3000 rpm.
If the rotor is being prevented from rotating, this will automatically be detected and the power supply will be cut out. Consequently, no extra motor protection is needed.
Overtemperature protection
A permanent magnet motor gives off very little heat to its surroundings. In combination with an efficient internal circulation system leading the heat away from the rotor, stator and bearings, this ensures optimum operating conditions for the motor.
As an extra protection, the electronic unit has a built-in temperature sensor. When the temperature rises too high, the motor is cut out; when the temperature has dropped, the motor is automatically cut in again.
Reliability
The motors are built for high reliability and feature:
- Tungsten carbide / ceramic bearings
- thrust bearings protecting against downthrust
- product life time equal to conventional AC motors
Important: Any well with a high static water level may allow the pump to operate off the curve and outside its recommended range. We recommend using a "Dole" flow restriction valve to throttle the pump to prevent upthrust damage to the pump and motor. The maximum flow must be restricted to within the pumps recommended operating range.
