PEDAL POWERED CENTRIFUGAL PUMP PURIFIED WATER SUPPLY DEVICE
Abstract
This paper analyzes the design of a pedal powered purified water supply device to be used by
local dwellers. It works on the principle of compression and sudden release of a tube by creating negative pressure in the tube and this vacuum created draws water from the sump into the pump while rollers push the water through to the filter where adsorption takes place to purify the water. The design composed a peristaltic pump powered by paddling, a carbon filter and hose or flexible tube. As the operator sits on the seat and paddles, the pedal crank transfer the motion to the rotor thus the rollers and the tube is squeezed by the set of rollers to move the fluid. The design analysis shows that one revolution of the pedal gives 1.1 litres of water. This design will reduce the labour, cost and weariness caused by transporting and sanitizing drinkable water for use in the homes of Ghanaian villages.
