Test Your Side Seals and O-Rings for Proper Seating

Posted on by

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.

The Right Transfer Pump

Transfer Pump in drumHaving the right transfer pump for your material is important for success. Not all pumps are the same. When looking at transfer pumps, look for a pump that can handle the materials you use, is easy to clean and can fit into the drum size you need. When in doubt, check your material against the transfer pump manual. This will help you identify proper ratio, cycles per gallon, psi and other important factors.

When to Perform Maintenance Checks

Avoid unnecessary down time by performing maintenance checks before you start your day. It is easier to perform these checks while the system is cool and pressure free. Taking this step saves you downtime later if something was wrong.

How to Fix your Transfer Pump – Before you Replace it

After 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. You can notice the spring wear off 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. In this situation, hanging 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.

Watch for Crystals Forming in your Hose

Posted on by

When winterizing and storing hoses over an extended amount of time, be sure to clean the system thoroughly. Often, the flush and remaining isocyanate will separate over time. With the isocyanate clinging to the hose walls, fittings and various locations throughout the equipment doesn’t come out 100% with an initial flush. As a result, when the hose is put back in service, the heating required will cause expansion – dis-bonding the settled isocyanate. To help prevent this, be sure to thoroughly flush the system and follow up with a second flush within 3-4 days. This action will allow time for the remaining isocyanate to settle and be cleared with clean flush.

PROCESS & DOCUMENTATION

Making a Record of Your Parts

Posted on by

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.
