It comprises a force head with packing, cylinder 600mm, piston with two rings and rod and suitable valves.


Force Head

The Jooste force head is applied to prevent water from discharging from the top of the column of pipes when pumping with a windmill thus delivering water higher than the surface. The packing is specially designed for durability, to last longer and minimise adjustment.
