Pin-Mount Rotary Spray Ball

Pin-retained inlet connection

The inlet collar uses a retaining pin or fastener as part of its attachment to the supply assembly. Compare the collar bore and retaining arrangement with the matching pipe connection. Leave access to fit and remove the retainer, and consider how the complete spray head will be withdrawn for service.

Rotary spray head construction

The rotary head has slotted openings and receives cleaning liquid through the inlet. Specify the rotary head and supply arrangement together for the required cleaning process. The pin-retained inlet also needs a suitable inspection and removal route, so the connection and the installed head position should be selected as one assembly.

Pipe-series dimensions

The drawing separates DIN, 3A, SMS and ISO collar-bore dimensions. Use the appropriate column and complete selected row when matching the inlet to the pipe. These separate references help identify a configuration; they do not make different pipe dimensions interchangeable.

Materials, positioning and maintenance

The listed series offers SS304 and SS316L over a nominal ½–2½ inch, DN15–DN65 series range. Check head clearance against the tank opening and internal equipment. Routine maintenance should include the retaining part and collar, moving head and spray openings, while coverage requirements are assessed across the complete vessel layout.
