Don’t run out of material in your transfer pump

When using your transfer pump a variety of issues can occur, the most common being running out of material. As soon as the pump runs out of material, it will cavitate from loss of fluid trying to pump air and most often run wild until the operator shuts it down. Having the pump run out of material can cause damage resulting in shut down repair time or even permanent damage to the pump, costing time and money to replace.  

Keep Your Material Warm

Having warm material is very important for spray foaming, however, it is easy to think a few degrees won’t make a difference. It is important for the health of your equipment and the quality of your work to wait for those few extra degrees to get you the best quality 

Remember to always warm up material to the manufacturers recommended temperature to get the best spray! 

Properly Trained Team

Taking time to properly train your team will prevent losses in both time and money. By investing in your employees, you are able to have them run more efficiently and spend less time fixing costly mistakes.

Training doesn’t always have to take a ton of time out of your schedule. Taking one day to train a group of employees on proper equipment handling, maintenance or basic trouble shooting can prevent hours of lost time. Afterall, spending a few hours to train your crew on taking care of equipment can prevent having hours or even days of downtime due to a preventable mistake.

Changing Over Material

Ventilation at the Job Site

It may seem redundant but, when spray foaming, keep your job site ventilated and do it every single time you spray. Keeping the work area ventilated will prevent unnecessary exposure to fumes and particles that can cause damage to workers. Best practice is to be aware of the airflow and have a source of entry and a way for air to flow out of the work space. Also remember to keep the area ventilated until the re-entry time specified by the foam manufacturer.  

For more information on proper ventilation procedures review the EPA Spray Foam Ventilation Guidelines 

Changing Hydraulic Oil in your Spray Foam Machine

What you need to know before changing hydraulic oil is when operating in ambient temperature recommendations of 0 to 90°F (-17 to 32°C) frequency is about 1000 hours or 12 months, whichever comes first and/or in  90°F and above (32°C and above) 500 hours or 6 months, whichever comes first.

Recommended Oils: 

Citgo A/W ISO Grade 46 Amsoil AWI ISO Grade 46 (synthetic*) BP Oil International Energol® HLP-HM, ISO Grade 46 Carl Bechem GmbH Staroil HVI 46 Castrol Hyspin AWS 46 Chevron Rykon® AW, ISO 46 Exxon Humble Hydraulic H, ISO Grade 46 Mobil Mobil DTE 25, ISO Grade 46 Shell Shell Tellus, ISO Grade 46 Texaco Texaco AW Hydraulic, ISO Grade 46 *

NOTE: After changing hydraulic oil and upon starting motor, hydraulic pumps may make a screeching noise until primed. If this noise continues for more than 30 seconds, switch off motor control and contact your machine manufacturer.

Graco T3 Transfer Pump Packing

Graco T3 Retaining NutAs a general rule, the shaft area of your Graco T3 Pump should be checked, cleaned and lubricated every three to six months. When you get a new T3 Pump and during these checks, run about 20 gallons of material. Afterwards, tighten the packing nut by hand and then use the included spanner wrench to tighten an additional 1/8 to 1/4 turn.

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.
