__NOTOC__ <small-title />
The Canzee hand pump is a direct-action handpump made with corrosion resistant materials such as plastic, stainless steel and wood. The pump uses two PVC pipes inside each other, each with a simple non-return valve made with a rubber flap.
===Construction, operations and maintenance===

The pump consists of two PVC pipes of different diameter, one inside the other. At the bottom of each pipe is a non-return valve made with a rubber flap which allows water to enter the bottom of the pipe, but not out again.
Except for the pump handle and the stainless steel pump rod, the Canzee Pump is made almost totally of plastic. The pump head is made from the extremely strong plastic ABS, which is UV resistant.
The down hole components such as the rising main and pump rod pipes are made of standard PVC-U pipes used for drinking water, and the plunger and footvalves foot-valves are machined from Polyamide. The only non-plastic components are the pumprod 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. The Canzee Pump is totally corrosion resistant because all materials used are either of plastic, wood or stainless steel.
The pump head, handle and rod weigh 3.0 kilos, while the combined weight of the two pipes is 1.0 kilos per metre. A complete pump kit, capable of lifting from a depth of seven metres, weighs about 10 kilos and is packed in packages no more than 2.0 metres long.
===Field experiences===

The Canzee pump is used in Madagascar, where hundreds of pumps have already been installed. Canzee pumps have also been used for years in Kenya, Ecuador, Israel, Morocco, Zimbabwe, Angola and other countries.
In the field, performance of the pump has been verified in several countries. Kenyan users report 3 years of continued use by 200 people, lifting water from 6 meters, before having to repair the rubber flap. In Uganda 2 years and 8 months passed before the first repair. In Madagascar, village pumps have continued to operate without breakdown for more than 2 years as well.<ref>[http://bushproof.biosandfilter.org/index.php?id=73 Bush Proof article about Canzee pumps.] </ref>
The NGO MEDAIR has been active in Madagascar since 2002, and is the first to have installed a large number of Canzee pumps. They worked in the Maroantsetra region in Madagascar in hydrogeologically hydro-geologically suitable communities in the rural areas. They found that in previous projects, not enough attention was paid to environmental issues. Especially in the context of installation in shallow wells, more careful siting is needed. <ref>[http://www.rural-water-supply.net/en/resources/details/173 The report by MEDAIR can be downloaded here]</ref>
