Theory of Operation
The Loctite Series 9000 Rotospray System operates as follows:
Refer to the Fig.1 on page 7.
• A customer-supplied slide positions the Rotospray Head and spinner disk inside the
bore to be treated.
• Gravity feeds the Loctite Product from the Reservoir into the pump and the Pump has been
cycled a sufficient number of times to fill the tubing between the pump and the Rotospray
Head with Loctite Product.
• The Air motor starts, rotating the spinner.
• The Pump cycles, dispensing a metered amount of Loctite Product onto the rotating
spinner disk.
• Centrifugal force moves the product across the disk surface until it reaches the edge
of the disk.
• At the edge of the disk, centrifugal force spins the product across the gap between the
edge of the disk and the ID of the part.
• The Loctite Product is applied as a ring or bead within the part bore.
• The air motor stops and the spinner stops rotating.
• The pump piston retracts.
• The customer-supplied slide returns the Rotospray Head and spinner disk to the
home position.
The Loctite Series 9000 Rotospray Pump is a pneumatically-operated piston pump.
Adjusting the piston stroke controls the amount of product dispensed. The amount can be
adjusted between 0.02 cc to 0.45 cc per stroke.
See Loctite Manual 983355 for both a more detailed description of the Series 9000 Pump and
an illustrated sequence of pump operation.
