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. The Loctite Rotospray Pump itself.

3. A Rotospray centrifugal force dispense head.

4. A product tube between the pump and dispense head.

5. An electro-pneumatic or pneumatic control system.

This manual will cover the Loctite Series 9000 Rotospray Pump part number 983330 only.

The Loctite Series 9000 Rotospray Pump is designed to pump anaerobic materials with viscosity <100,000cps that can be gravity fed to the pump. The pump displacement range is

0.02 cc to 0.40 cc.

Typical Loctite ® Products are:

Loctite product 271 ™ , 277, 620, 635, 640, 11264, 11358, 11747, and 12019.

The Loctite Rotospray Pump is not suitable for dispensing moisture cure products such as RTV Silicones or Cyanoacrylates.

Because The Loctite Rotospray Pump is pneumatic, the only utility needed is compressed air.

See the specifications on page 14 for the air quality requirements.

Because anaerobic products are being dispensed, the parts which come in contact with the Loctite Anaerobic products are made as inert as possible. This helps prevent product curing within the system. In addition, the pump is designed with a minimum of dead areas or close clearances where anaerobic curing can start.

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.

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.

Adjusting Pump Dispense Volume

The black knob on the back of the pump is used to set the stroke of the pump which controls the amount of product dispensed per cycle. The knob should be turned fully clockwise then counter clockwise one full turn. You should then cycle the pump and check to see if the proper amount of product is being dispensed. Continue to adjust the knob until the desired amount is dispensed. Turning the knob clockwise reduces the amount dispensed and turning counterclockwise increases the amount. Plus and minus arrows on the stroke adjustment knob indicate the volume increase and decrease directions.

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. If the pump is to be idle for longer than one (1) month, both the pump and the product lines should be serviced. Remove and replace product feed lines. Return the pump to a Loctite

Service Center for cleaning and/or rebuilding.

4. If a gravity feed reservoir is being used, refer to the reservoir manual for idle time information.

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. Shut off air supply and relieve pressure from air lines.

2. Disconnect the air lines and product feed lines from the pump module. Elevate the feed line above the reservoir to prevent product leakage from the feed line.

3. Position and hold the pump assembly so that the stroke adjuster knob is facing you with air line connectors pointing straight up (12 o’clock).

4. Rotate the stroke adjuster knob counterclockwise to the full open position.

5. Rotate the knurled black locking ring clockwise by hand until it bottoms out or stops turning.

6. Gently push the pump module towards the actuator module and rotate the pump module clockwise approximately 90 degrees until it stops.

7. Disengage the pump module from the actuator module by pulling them apart.

To Assemble

1. Push stroke adjuster knob in to advance pin connector.

2. Carefully position a new pump module onto the actuator module; the feed line connector should be at (3 o’clock) position, and push together until fully seated.

3. Rotate the pump module counterclockwise approximately 90 degrees or until it stops.

4. Rotate the black locking ring by hand counterclockwise until tight against face of the actuator.

5. Reconnect product feed lines and air lines to pump assembly and set stroke adjuster knob to dispense desired amount.
