Description
When your windmill is tasked with pushing water uphill or into a pressurized storage tank, the 50mm Force Head is your most critical component. Because force heads operate under significantly higher stress than standard cylinders, maintaining a perfect seal is non-negotiable.
The BC 50mm Force Head Kit is built to restore the high-velocity displacement and airtight integrity of your system. Using premium, oil-treated leather and high-tension seating rings, this kit ensures that your force head remains efficient even in deep-bore or high-head applications across the South African interior.
What’s Inside the Kit:
-
Premium 50mm Leather Cup Seal: Specially selected for high-pressure expansion to prevent water bypass during the power stroke.
-
1x 50mm High-Tension Snap-Ring: Precision-engineered to lock internal components against extreme vertical force.
-
1x 50mm Heavy-Duty Cylinder O-Ring: A chemical-resistant rubber seal designed to maintain a vacuum-tight fit at the base of the force head.
-
1x Reinforced Connecting Rod Guide: High-durability threading to ensure the 50mm rod remains perfectly aligned under load.
- 50mm Cylinder Force Head Barrel: High-durability built to last for maximum performance in the field.
Why This Kit is Essential:
-
High-Lift Reliability: Specifically designed for systems where water must be forced to a higher elevation than the windmill itself.
-
Eliminate Pressure Drop: Optimal seal in the 50mm head to immediate volume loss for “tight-fit” high-pressure delivery.
-
Friction Reduction: All components are surfaced to work seamlessly with the honed internal finish of the 50mm BC barrel, reducing mechanical drag.
-
Tailored 50mm bore size: Avoid the “universal fit” trap—these parts are machined to the exact tolerances of the 50mm force head configuration.
