A pump for drinking water and limited use for irrigating gardens.
The Canzee pump is a direct action pump initially developed in New Zealand. It uses a simple pumping principle. It consists of two pipes, one slightly larger than the other. At the bottom of each pipe is a non-return valve. The pumping movement raises and lowers the inner pipe. The outer pipe remains still. When the inner pipe is raised it lifts the water contained within it. The atmospheric pres-sure pushes more water into the outer pipe. Each stroke lifts the water in the inner pipe to the top until it runs out through the spout. The pump is self-priming. A thin film of water between the two pipes ensures they do not touch: the pump lubricates itself. The Canzee pump is designed as family pump for serving user groups of about 100 to 150 people. It can be used for irrigation of family gardens. Like all direct action pump the operation is not ergonomically favourable, therefore prolonged pumping is not possible.

Materials used

The above-ground components (pump head and pump body) are designed for easy dismantling; the material is ABS, a material that is Ultra-Violet resistant.

The down hole components like rising main and pump rod pipes are made of standard uPVC pipes; The plunger and foot valves are machined from Polyamide; The only non-plastic components are the pump rod (stainless steel) the pump

handle (local hardwood) and a number of bolts, nuts and washers (galvanized steel), which are not in direct contact with the water pumped, thus Pump is corrosion resistant.

Installation and Maintenance

The installation of the Canzee pump is easy and does not need any lifting equipment or special tools. The pumps are generally installed in dug wells or boreholes. This pump has an excellent potential for maintenance by the users. All repairs can be done with few tools. Only one spanner and one nail are required to dismantle the whole pump.

Artisan workshop: small scale production of handpumps in small workshops with few tools using locally available materials. The Canzee Pump has been designed so that the majority of plastic materials used are readily available on the market and only few machining operations are needed for finishing the pump components. Therefore simple manufacturing equipment is required (small lathe machine and a number of tools and fixtures).


Approx USD 100-200 excluding the borehole tube well (depending on installation depth, local material and labour costs)


About 500 – 1,000 Canzee pumps have been installed in Madagascar. Canzee pumps have also been used in Uganda, Kenya, Tanzania, Zimbabwe and Angola.
