The Sub Assembly is used to attach a submersible pump onto a cylinder (AS or RDS), enabling the use of the windmill and a submersible pump.
The pipe protectors are fitted onto the rods in the riser pipe and prevents the rods from ‘rubbing’ against the pipes. Two pipe protectors per rod should be fitted just below the thread of the rods (at either end of the rod). A must for every borehole.
A Strainer Adaptor with sieve can be fitted, to the bottom of the cylinder. The sieve prevents the intake of foreign objects into the cylinder that can damage the valves.
The stroke adjuster facilitates the task to adjust the stroke and can be installed between the galvanised rods and the wooden rod of the windmill.
The rust retainer is fitted on the last galvanised rod, before the cylinder, preventing rust or sand from settling in the cylinder.
The Acetal Adaptor can be fitted to the bottom of the cylinder to accommodate a submersible pump or extension pipes and is part of the Sub Assembly.
The Adaptor Foot Valve is manufactured with female thread and is fitted to the bottom of the cylinder to accommodate a submersible pump or extension pipes.
The force head is fitted into a T-Piece on the last riser pipe to prevent water being forced out at the rod. The force head is available for 12mm and 16mm rods.
