Over the past five years, Comet-ME has developed a simple, reliable, low-cost solar-powered water pump, which will offer a game-changing water-delivery solution for off-grid rural farmers and communities in the Global South.
Comet-ME Solar Magnetic Plunger Pump (SMPP)
The Solar Magnetic Plunger Pump (SMPP) is a first-of-its-kind, double-action, submersible borehole piston pump designed for shallow aquifer pumping (with a pumping head in the range of 10-45 m) that can deliver 20-30 cubic meters a day, enough for irrigation of up to 1 hectare per day or for daily domestic usage for a small community.
Four key features of the SMPP make it competitive against similar products on the market:
- The SMPP’s competitive target purchase price of one-half that of leading pumps on the market will make it a desirable and affordable product for even the poorest farmers.
- Robust and very simple design, single moving part, and ease of serviceability lower the overall cost of ownership for the end-user.
- The SMPP is more reliable than centrifugal or helical pumps in the presence of sand particles in the water.
- The SMPP includes an integrated monitoring unit that provides flow data, allowing for PAYG and other remote billing schemes

SMPP Technical Paper
The SMPP’s innovative design takes the ancient and proven piston pump technology and transforms it into a high-flow, robust, simple, and reliable solar pump that outdoes existing solar pumps on the market in efficiency, serviceability, operation in a high-sediment environment, and of lowest cost of ownership.
