When you need a water pump for larger jobs, just convert your Simple Pump manual water pump into a motorized pump.
Our 1/5 hp DC motor attachment quickly bolts on to operate reliably in any climate.

In addition to all of Simple Pump's design advantages, the motor attachment is made with uncompromising efficiency and durability.

You can easily upgrade an existing hand-operated pump to a motor because of our highly-accurate computer-machined parts. Always identical computer machining assures precise part-to-part fit — even years in the future.
The mounting of the motor takes only a few minutes, and you can just as easily go back to hand-operation, if ever necessary.

Driving the Motor

Any source of 12 volt DC current can then be used to drive the motor.

Running on Solar

Simple Pump is so power-efficient, it can, in many parts of the US, be run from one 130W solar panel.
In cloudier areas, two panels may be needed.

Recommended operation is to use the solar to charge batteries and run the motor from the batteries.
But the pump can also operate directly from a solar panel with a linear current booster installed.
