SPRAY GUNS

Fix Your Transfer Pump – Before You Replace It

PMC GHO, IPM OP series, Graco T2 Transfer Air motor performance

Rebuilding the entire transfer pump can get expensive and may not be required. After much use, the transfer pump air motor starts operating sluggish and leaks air. This is generally due to deforming (wear) of the upper reversing spring and the upper air valve gasket. The spring shows this wear generally in two ways. The first being the pump fails to return to the down stroke and secondly the pump will pause momentarily when reversing to the down stroke which appears as a cavitation type action. Changing the spring is the best solution, but when in a pinch, stretching the spring to its near original length can get you through the day.

Test Your Side Seals and O-Rings for Proper Seating

After replacing the o-rings in your AP-2 Gun, it’s important to make sure they are sealing properly. In order to test if the side seals are seating properly and the o-ring is sealing, follow these steps:

With the safety on and the gun disconnected from the hose, hook an air hose onto the gun and pull on the trigger. This pulls the chamber back slightly which cuts the airflow coming out of the tip. The air should cease from blowing out of the tip and should only slightly exhaust at the vent near the handle and the air-motor. If the side seal, the o-ring around the side seal or the oring at the screen screw is not sealing the air will push out of the check valve seat.

Making a Record of Your Parts

Proper part identification is extremely important to ensure you are receiving the correct part for your machine. If a part is ordered by the wrong number, the wrong part is shipped and extra shipping charges are incurred for returns. But more important than the extra shipping involved, is the possible loss of production time that this unnecessary delay may cause you.

I recommend making a record of all part numbers, as equipment is purchased. This will help prevent delays and added expense.

Weather Conditions

As seasons begin to change, it’s easy to overlook the still-frigid-nights with the sunny days. Temperatures fluctuate from day to night, even in the spring and summer, so I recommend keeping your material stored and warm overnight. Don’t let the sun fool you!

Clean your screen filter

Materials entering the proportioning unit may require screening or filtering. Therefore, manufactures of the spray equipment commonly install y-strainers or filter housings on or near the machine to pre-screen the materials as they are transferred from the storage vessel prior to entering the proportioning unit. Proper cleaning or replacement of the screen filter must be completed daily or as needed to ensure proper material supply is achieved. Clogging and restriction of the screen filter may cause cavitation and/or poorly dispersed product known as off-ratio.

Restoring an Iso Hose

After several years of service, iso will form a buildup within the hose. We recommend doing a thorough strip and rinse of these hoses to assure full flow performance. Order our SprayWorks Power Flush System to restore those aging iso hoses or when winterizing the system. You’ll be amazed at the amount of old cured materials that will come out.

Prepare for Cold Weather

With the cold weather quickly approaching and roughly 20 good working days between now and Thanksgiving, it’s important to make the most of product yield and production by being prepared. Make sure drums are warm and ready for the job by keeping them heated with products such as the Barrel Blazer heating system. Temps are dropping in evening, so container temps are going to drop. Plan ahead and be effective!

Gun Cleaner for Minimizing Wear on Parts

Torching, picking, sanding, and wire brushing off the gun and related parts often does more damage than good. At best, it cleans the parts but accelerates service life by abrasive cleaning. Utilizing an effective gun cleaner to reduce excessive cleaning of parts is recommended. Generally, a quality gun cleaner can clean parts within 15-20 minutes when the gun cleaner is heated overnight at room temperatures.
