This pump is an improved & VLOM (Village Level Operation & Maintenance) version of the India Mark 2 hand pump.
Mark 3 uses riser pipe of 65mm Nominal Bore as compared to 32 mm in Mark 2. Therefore the cost of riser pipes is twice in Mark 3.
The Cylinder Assembly is totally different from Mark 2, the bottom cap is to suit the check valve and top cap is to facilitate extraction of the plunger and check valve assembles for repairs without lifting the riser main.
The Water Tank in Mark 3 has a 65 mm steel socket to accommodate the 65 mm riser pipe.
