The Rower pump was developed as a simple manually operated pump for small scale irrigation. The Rower Pump is a suction pump in which the piston is directly activated. A surge chamber (an air vessel just downstream of the foot valve, makes the pumping operation smoother). It is a simple and reliable pump with very few moving parts thus wear is reduced.

It is easy to repair and maintain. The sitting position of the operator is ergonomically favourable and makes it easy to pump for prolonged periods, thus well suited for irrigation. The pump has limited use for drinking water as the spout is relatively low. Typically, Rower Pumps are installed in collapsible tube wells with the screen extending to the coarse sand aquifer.

===Suitable conditions===

About 200,000 pumps have been made in Bangladesh.

===Construction, operations and maintenance===

[[Image:rower pump2.jpg|thumb|right|200px|Rower pump is basically a suction plunger pump. Drawing: [http://en.howtopedia.org/wiki/How_to_Build_Human-Powered_Water-Lifters How to Build Human-Powered Water-Lifters.]]]

Industrial production: large scale production in local or foreign industrial units. The cast iron design required foundry equipment and skills.

===Costs===

Approx US$ 100-200 including tube well (depending on installation depth and drilling method).
