Clean-in-place (CIP) only works if every interior surface sees the spray. A pin fixed rotary cleaning ball is built to do exactly that: spin on a fixed pivot and throw cleaning fluid across the full tank. This article explains the mechanism and why it reliably reaches 360°.
Unlike a freely rotating ball, the pin fixed design locks the ball onto a stationary pin at the tank dome. The pin sets the rotation axis and keeps the orifice pattern stable, so the jet map is repeatable from cycle to cycle instead of drifting.
Cleaning-fluid pressure drives the ball to rotate; as it turns, the angled orifices paint the walls, dome, and base with overlapping cones. Because the axis is fixed by the pin, the pattern is predictable and the ball can be positioned to cover the far wall and the bottom simultaneously—that overlap is what eliminates shadow zones.
A static sanitary fixed cleaning ball wets only its direct line of sight. The sanitary rotary cleaning ball family—including the pin fixed version—adds rotation for 360° coverage at a lower flow than a rotary jet washer.
| Factor | Pin Fixed Rotary Ball | Fixed (Static) Ball |
|---|---|---|
| Coverage | Full 360° with overlap | Line-of-sight only |
| Rotation | Pin-anchored, repeatable axis | None |
| Reach | Walls, dome, and base | Spray cone front only |
| Best use | Routine CIP of process tanks | Simple rinse of small vessels |
Coverage depends on ball position, tank diameter, and flow and pressure. Place the ball high in the dome, size flow to the manufacturer’s recommended pressure, and verify the spray cone reaches the bottom and sidewalls. EFUN’s cleaning balls are machined to 3A and ISO for hygienic service and pair with the rest of the sanitary tank accessories range.
Engineer a 360° CIP wash for your tank
Send tank dimensions and CIP pressure—EFUN recommends a pin fixed or rotary ball with verified coverage for your vessel.
It fixes the rotation axis via a central pin, so the ball spins around a known center rather than drifting—giving repeatable 360° coverage cycle after cycle.
No. A rotary jet head uses higher pressure and fewer, harder jets for heavy soil. A pin fixed rotary ball uses lower flow and full-cone coverage for routine CIP—lower cost and gentler on product-contact surfaces.
Model the spray cone against tank geometry, or run a dye / CIP verification. Position the ball centrally in the dome and size flow to specification.
