Construction, operations and maintenance
India Mark ll
The Mark II is a closed-cylinder pump. The cylinder brass-lined cast iron with the foot valve and piston assemblies made of brass. The piston seals are double nitrile rubber cup seals. The top and bottom of the piston cylinder are “capped” with threaded reducers. The diameter of the pump cylinder is larger than the diameter of the riser main to which it is attached.
Maintenance on any part of the pump cylinder requires that the riser main and the pump rod be removed from the ground.The pump rod is galvanized steel and sections are threaded together. The pump cylinder is threaded onto the last section of riser main and is removed in its entirety as the last component to come out of the ground. The pump cylinder can then be unscrewed from the riser main. The top and bottom caps can be unscrewed from the cylinder body to gain access to the foot valve, the piston valve, the piston seals and anything else inside the cylinder body.
