Frequently Asked Questions - Lobe Vacuum Pump Wash System Coburn

What does the Coburn Lobe Pump Wash System do?

It automatically injects cleaning chemical into the intake side of a vacuum pump during the pipeline wash cycle to prevent buildup of dirt, milk fat, or other foreign material on the pump lobes.

What is included in the box?

The system includes one Lobe Wash Pump (#1205356), one Straight Injector Fitting (#051466), and 10 feet of 1/4" OD chemical tubing (#62240). The cleaning chemical is not included but recommended.

Which vacuum pumps is this system compatible with?

It is designed for Coburn lobe vacuum pumps, with sample settings for 10, 15, 20, and 25 HP pumps. It can be adapted for other sizes by adjusting the speed, recharge, and prime dials.

What are the electrical requirements?

The unit accepts 115 VAC or 230 VAC. For 90-115V input, connect the green and black transformer wires; for 230V input, connect the red and green wires. All wiring must comply with state and local codes.

How do I program the pump?

Flip the rocker switch to ▶▶ to prime the chemical lines. Open the front lid and gently turn the dials using a small screwdriver. Adjust SPEED (1-100%), RECHARGE (0-20 sec or continuous), and PRIME (0-190 sec) as needed.

What are the recommended settings for 10 and 15 HP pumps?

For 10 & 15 HP pumps, use the sample settings shown in the manual to deliver about 3 oz. of pump wash chemical per cycle. Adjust as needed based on your wash system.

What are the recommended settings for 20 and 25 HP pumps?

For 20 & 25 HP pumps, use the sample settings shown in the manual to deliver about 6 oz. of pump wash chemical per cycle. Adjust as needed for your specific conditions.

How do I operate the system?

Turn the rocker switch to ▶▶. The green LED will light steadily when the pump is energized by the pipeline washing system. If the LED does not light, power is not being supplied to the unit.

What maintenance is required?

Typically, the chemical tubing should be replaced about once per year. Always turn the rocker switch to off (⏻) and ensure the power source is disconnected before any maintenance, as high voltage can be present even in the off mode.

Why is my green LED blinking?

A blinking green diode indicates the rocker switch is in the off (⏻) mode but the unit has been activated during a pipeline wash. This is a standby indicator; ensure power is disconnected before opening for service.

USER MANUAL Lobe Vacuum Pump Wash System Coburn

Lobe Vacuum Pump Wash System

Your #1205300 Lobe Vacuum Pump Wash System should include the following parts:

One # 1205356 Lobe Wash Pump (Pictured on front)

One # 051466 Straight Injector Fitting

10 feet of # 62240 1/4" OD Chemical Tubing (Not Pictured)

Not included but recommended: #5600-1 (1 gallon) or #5600-5 (5 gallon) Coburn Lobe Pump Wash Chemical

Installation

1. Choose a convenient location in the vacuum line on the intake side of the vacuum pump to locate the injector fitting. Mark the location. This fitting should be mounted as close as possible to the inlet port on the vacuum pump.
2. Drill a 5/16" hole in the vacuum line, then use a 1/8-27 NPT pipe tap to cut threads into the pipe. Be sure to protect the pump and piping from debris.
3. Thread the injector fitting into the intake pipe until snug. The eccentric center tube of the injector should be on the pump side of the threaded holes center.
4. Choose a convenient wall location close to the vacuum pump to mount the lobe wash pump. Secure to wall with anchors appropriate for the wall material. Total distance between the wash chemical container and the inlet on the vacuum line including the pump should be ten feet or less. Make sure it is out of the way but still provides easy access.
5. On the intake side of the vacuum pump, attach one end of the 1/4 ” OD chemical tubing to the injector fitting using the nut supplied on the injector fitting.
6. Measure the distance from the injector fitting to the discharge side of the lobe wash pump. Route the hose as short as possible without any kinks. Cut hose and secure to the right side of the pump using the nut supplied on the pump. Secure hose with customer supplied nylon ties if required.
7. Place lobe pump wash chemical container in a convenient location as close as possible to the lobe wash pump.
8. Attach one end of the tubing to the left side of the pump using the supplied nut.
9. Place the other end of the tubing into the container of lobe wash chemical and secure as necessary.
10. Connect lobe wash pump wires to 115 VAC power source. Transformer green and black wires are for 90-115V input. If power is 230 VAC, open unit and connect power to 230 VAC input red and green wires.

Note on Electrical Connection: All electrical wiring should be completed according to state and local wiring codes. The pump should run with the automatic pipeline washer and be powered from its diverter, cycling once during the pipeline wash process. If your pipeline wash system doesn't have a diverter valve, contact The Coburn Company to discuss other options.

Programming

A properly set system will automatically inject enough cleaning chemical into your vacuum pump during the wash cycle to prevent build up of dirt, milk fat or other foreign material on the pump lobes.

1. Press rocker switch on ▶▶ to prime chemical lines
2. Flip open lid on front (See image at right) and turn dials gently with a small straight blade screwdriver to program:

SPEED = How fast the pump rotates. Faster rotation supplies

more solution.

Adjustable between 1-100%

RECHARGE = Pump running time (in seconds) to “recharge the line” with chemical after it first receives power from the Automatic Pipeline Washer. There will be an approximately 13 second delay after the pump shuts off before the prime cycle starts.

Adjustable between 0-20 seconds, or continuous run for rinse applications

PRIME = Pump running time (in seconds) after the recharge cycle stops.

Adjustable between 0-190 seconds

Sample Settings

SPEED

RECHARGE

PRIME

The above settings deliver about 3 oz. of pump wash chemical for 10 & 15 HP vacuum pumps (Adjust as needed)

SPEED

RECHARGE

PRIME

The above settings deliver about 6 oz. of pump wash chemical for 20 & 25 HP vacuum pumps (Adjust as needed)

Operation

To run Lobe Pump Cleaner, turn rocker switch on ▶▶. Green diode will be lit and steady, and pump will run when energized by pipeline washing system. If green diode is not lit, power is not being supplied to the unit.

Maintenance

To change tubing (usually no more than once per year), turn rocker switch off ⏻. Green diode will be lit and blinking when the rocker switch is in this mode if activated during pipeline wash mode. Never open unit without ensuring power source will stay off—high voltage can be present, even with rocker switch set to off.
