The Zimbabwe Bush Pump: "Open top cylinder" model Installation Manual with notes on maintenance

Description:

The standard and most commonly used version of the Zimbabwe Bush Pump uses down the hole components comprising 50mm galvanised iron pipe, 6mm mild steel pump rods, a 75mm brass cylinder with matching piston and heavy duty foot valve. The 75mm piston is fitted with two leather piston seals. The two piston seals are the fastest wearing part of any Bush Pump, and in the standard version, their replacement requires the lifting of the rising main (steel pies) to gain access to the piston and its seals. This is routine practice in Zimbabwe.
