Pin-Mount Rotary Spray Ball — Short Neck

Short collar and pin retention

The short inlet collar is part of the connection to the supply assembly, with a retaining pin or fastener used for mounting. Compare the collar fit and retaining details with the actual pipe connection. Provide access to insert and remove the retaining part after adjacent equipment is installed.

Moving head with slotted openings

Cleaning liquid supplied through the inlet reaches the rotary head and its slotted openings. Select the head and supply arrangement together for the required process. The short collar keeps the inlet close to the moving head, so the selected connection should be checked together with head clearance and access to the retainer.

Installed envelope and maintenance route

The short neck places the spray head close to its inlet mounting point. Check the head envelope and access route against the tank opening, nearby pipes and internal equipment. Plan how the component can be removed for inspection, in addition to checking the space needed when installed.

Listed options and replacement checks

The listed series offers SS304 and SS316L with a nominal series range of ½–2½ inches, DN15–DN65. Confirm the selected inlet dimensions and retaining arrangement before ordering. Routine inspection should cover the retainer, collar, moving head and slots, while the required spray coverage is evaluated for the complete vessel layout.
