A Graco Transfer Pump keeps spray foam jobs moving. It feeds material from the drum to your proportioner. The flow stays steady, so your spray is smooth. Graco Equipment is made to last and easy to use.
This guide reviews five pumps: T1, T2, T3 Carbon Steel, T3 Stainless Steel, and T4. You’ll see what each does best and how to choose the right one.
What Is a Fluid-to-Air Ratio?
The fluid-to-air ratio shows how much material moves for the air pushing it. Higher numbers handle thicker foam or coatings. Lower numbers work well for lighter spray jobs. Knowing this helps you match the Graco Transfer Pump to the job.
Graco T1 Transfer Pump (part #256200)
The Graco T1 Transfer Pump is made of stainless steel. It has a 2:1 ratio. It is simple, strong, and needs little care.
Key benefits:
- ✅ Steady pressure for smooth spraying
- ✅ Works well in all weather
- ✅ Built by the leader in pump design
- ✅ Long life with low upkeep
Choose the T1 if you want a basic, reliable Graco Equipment pump for daily work.
Graco T2 Supply Pump (part #295616)
The Graco T2 Transfer Pump is stronger than the T1. Its 2.25:1 ratio gives extra power for thicker materials.
Key benefits:
- ✅ Even flow for a smooth spray pattern
- ✅ Lower pressure drop with heavy materials
- ✅ Stainless-steel build for long life
- ✅ Low maintenance needs
The T2 is a smart Graco Equipment upgrade when you want more pumping strength.
Graco T3 Carbon Steel (part #24Z834)
The Graco T3 Transfer Pump improves on the T1 and T2. It has a 3:1 ratio for heavy materials. This carbon-steel model is 3.7 inches shorter than the T2, making it easier to handle in a rig.
It runs much quieter — about three times quieter than the T2. It also needs less service because it uses pneumatic switching instead of mechanical parts.
Key benefits:
- ✅ Shorter height for quick drum changes
- ✅ Quieter for better work conditions
- ✅ Less upkeep with fewer moving parts
Pick the T3 Carbon Steel for a Graco Transfer Pump that blends power, comfort, and durability.
Graco T3 Stainless Steel (part #24Z987)
The Graco T3 Stainless Steel Transfer Pump Package gives you all the benefits of the carbon steel version plus corrosion resistance. It comes with two pumps, two hoses, an air supply kit, and a dryer kit.
Key benefits:
- ✅ Same quiet, low-maintenance design as the carbon-steel T3
- ✅ Extra protection from rust and wear
- ✅ Complete kit for fast setup
Choose the T3 Stainless Steel if you want a ready-to-use Graco Equipment package that will last for years.
Graco T4 Carbon Steel (part #26D001)
The Graco T4 Transfer Pump is made for speed. It has a 3:1 ratio and a quick-disconnect motor. This lets you change drums fast without messy drips.
Key benefits:
- ✅ Quick drum changes without spills
- ✅ Light and easy to move
- ✅ Replaceable parts to cut downtime
The T4 is the Graco Transfer Pump for you if you swap materials often and need to keep spraying.
