Increasing the Life Span of Hand Pump by providing inner liner in the body of Hand Pump (Shallow Hand Pump / Bucket Hand Pump)
Innovator: Mr Selvam T.
Location: Nagappattinam, Tamil Nadu
Category: House Hold Innovations,Equipments,Day to Day Utility
Keywords: handpump, liner tuber, 0.5 h.p. motor.
Details
The New Design : In 5 H.P oil engine the liner inside the cylinder is usually discarded in the old engine. Therefore procured the liner measuring about 1 feet length and thickness of 4 mm. He fitted this liner / sleeve inside the body of the hand pump (Above the ground level). The liner has been fixed by welding or through making grooves on both side of liner tube locally called thread making. This type of the liner with hand metal withstand frequent motion of piston and resists any damage of cylinder. Dissemination : Sri. Selvam after using his model very well satisfied. His neighbours found his innovation is worth while and approached for this alteration in their hand pumps. Over the last 3 years he has made such modification in 150 hand pumps / bucket pumps. However this innovation is not at all known to hand pimp users in other district. Sri.Selvam is now planning to use this liner system in 0.5 1 H.P motor operated bore well pump. By using this model motor alone is sufficient to lift water and there is no need for fitting pump. Therefore the cost of pump (up to Rs.4,000) can be saved in this proposed idea.

Benefits
· The liner is made up of hard steel cast iron and therefore it will not subject to easy wear and tear. · The life span of the hand pump is increased from 5 to 40 years or so. · The operation is easy as the piston rod moves up and down smoothly
