__NOTOC__ <small-title />
The Afripump, also called the Blue pump, 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 the upgrade to communities with existing Volanta pumps. Below is the story and details of how the Afripump came to be more useful and some information about the Volanta pump, for those still existing in use.
====First came the The Volanta pump====The Volanta Pump, created DGIS in co-operation with 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 installation depth is 70 50 m.
The Volanta Pump is not in the public domain and information can be asked from the manufacturer. The Volanta Pump is fully corrosion resistant. It is rather difficult to install and it needs extensive masonry work. Maintenance Regular maintenance is easy so that communities can care for the pumps.
