The Extra Deepwell hand pump is used to lift water from depths greater than 50 metres. It suits static water levels between 50 and 90 metres, with the cylinder placed up to 85 metres deep. SKI has made hand pumps since 1961 and manufactures Extra Deepwell hand pumps in Patna, India, under an ISO 9001:2015 quality system.
What is an Extra Deepwell hand pump?
An Extra Deepwell hand pump is built for places where the water is deeper than a standard hand pump can reach. It is based on the India Mark 2, with a modified head, a thicker handle and a different cylinder assembly, so it can draw water from greater depths.

How it differs from the India Mark 2
Most components are the same as on the India Mark 2. The head assembly is slightly different, and the handle is thicker: it is made of 40 mm square instead of the 32 mm square used on the Mark 2 and Mark 3 pumps. The cylinder assembly is different too, and combines India Mark 2 and India Mark 3 components.
How the Extra Deepwell pump works
The surface handle drives a pump rod inside the rising main. At the bottom of the borewell, the cylinder’s plunger lifts water through the rising main to the spout, while the check valve helps prevent the water column from flowing back down.
These illustrations explain the main parts and are not to scale. Confirm the borewell size and required cylinder placement for the site before ordering.
Cast iron or stainless steel cylinder
Normally, a cast iron cylinder assembly with gun-metal components is used for the Extra Deepwell hand pump. Where the water is corrosive, an SS 304 cylinder assembly is also available, as shown in the pictures below. See our stainless steel components page for the SS 304 cylinder, connecting rods and riser pipes.
Check your borewell before you order
