1 Warnings and Precautions • OBSERVE ALL WARNINGS. READ and UNDERSTAND all instructions in the manual before attempting to install and operate this equipment. • This equipment has been designed and tested for use with Loctite® anaerobic products. • DO NOT USE equipment for other than intended use. • BE SURE that all adhesives, solvents, or fluids used are chemically compatible with the wetted parts of the equipment.
2 Introduction The Loctite® Series 9000 Rotospray Pump will apply a metered amount of Loctite® anaerobic products to a Rotospray centrifugal force dispensing head. The Loctite Series 9000 Rotospray Pump is pneumatically operated and needs a 4-way pneumatic valve to control the pneumatic signals. The Loctite Series 9000 Rotospray Pump is usually part of a system that consists of the following components: 1. A gravity reservoir to supply product to the Loctite Rotospray Pump. 2.
3 Installation Inspection Before Installation The Loctite Rotospray Pump was inspected before shipment. Check the items in the shipping container against the list on Page 3 of this Manual. After removing the items from the shipping container inspect them for visible damage. Promptly report any damaged or missing parts to both the shipper and your Loctite representative.

4 Theory of Operation The Loctite Series 9000 Rotospray Pump is a pneumatically-operated piston pump. It has a single ball type check valve at the outlet and a flooded inlet. The piston stroke is adjustable to control the amount of product dispensed. Fig. 2 below shows the sequence of operation: PISTON RETRACTED, CHECK BALL ON SEAT, METERING CYLINDER FILLED WITH PRODUCT. PISTON MOVING FORWARD, CHECK BALL OFF SEAT, PRODUCT DISPENSED.
5 Operation Priming the Pump (first time use) 1. Set the pump stroke to maximum. 2. Move the pump piston to the fully retracted position. 3. Fill the reservoir with product. 4. Disconnect the 3/8-inch OD tube from the pump inlet. 5. Let the product flow to within 1/2-inch of the end of the 3/8-inch tube, then reconnect the tube to the pump inlet. 6. Cycle the pump. 7. Continue to cycle the pump until air-free product flows at the dispense point.
6 Maintenance Routine 1. Inspect air tubing, product tubing, and fittings for cracks, kinks or breaks and replace, as required. 2. Drain the air line filter bowl, if necessary. Idle Time 1. If the pump is in daily use, you do not need to service the pump or product tubing to prevent product curing unless a contaminant is introduced into the system. 2. The pump and tubing can be left idle for as long as one (1) month without curing under normal temperature (70° - 80°F). 3.
6 Maintenance, cont. Replacing The Pump Or Actuator Module The rotospray pump consists of a pump module (part no. 983117) and an actuator module (part no. 983116). In most cases, the pump module is the one replaced. WARNING: Failure to correctly change out the pump module(s) will result in DAMAGE. No tools are required to connect or disconnect the pump from actuator. If any forceful effort is required, the assembly is not correct and the instructions should be reviewed. To Disassemble 1.
7 Troubleshooting Possible problems and solutions for the Series 9000 Rotospray Pump. Problem Pump does not dispense product and the Stroke Adjuster Knob does not move when the pump is cycled. Troubleshooting Guide Cause No air supply. Turn on air supply. Low air pressure. Adjust air pressure to at least 60 psi. Stroke Adjuster Knob set to zero stroke. Reset Stroke Adjuster Knob. Pump air actuator defective. Replace actuator. Control valve faulty. Replace control valve. Control logic problem.

9 Series 9000 Pump Rebuilding Program The Series 9000 Pump is not field serviceable. Our rebuilding process ensures that the pump is free of contaminants and assembled to proper specifications reducing the possibly of a premature failure or unsatisfactory performance with Loctite products. This is accomplished by: • Ultrasonically cleaning the parts in the proper solvents for a predetermined time. • Pretreating all the wetted components to ensure a passive surface. • Using proper replacement parts.
