__NOTOC__

The Afripump is an upgrade from the Volanta pump. It no longer has a flywheel, is cheaper, and is said to be more reliable. The Afripump is upgradable to communities with existing Volanta pumps. Below is the story and details of how the Afripump came to be more useful. ====First came the Volanta pump====The Volanta Pump, created by Jansen Venneboer B.V. , is a reciprocating pump driven by a large flywheel for medium to very deep wells. It uses a retractable cylinder and a seal-less stainless steel piston. A crank and a connecting rod convert the rotary motion into a reciprocating action, which is transmitted to the plunger via stainless steel pump rods. The crankshaft and the flywheel run on ball bearings mounted on a plate that can be fixed to a steel or concrete pedestal. The cylinder is of glass fibre reinforced plastic with a close-fitting seal-less stainless steel plunger. The complete cylinder can be lifted from the well by the threaded pump rods, without removing the PVC-U rising main. The stroke is adjustable to reduce the effort needed at deep installations.

It is designed for heavy-duty use and the maximum recommended lift is 70 m.
