The Volanta Pump 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.
