Description

The Graco 26A304 T3 stainless steel transfer pump offers professional contractors a high performance, low maintenance solution for moving polyurethane foam and polyurea A- and B-materials. With a 3:1 fluid-to-air pressure ratio it achieves the required fluid pressure using less air input, and is rated for up to 315 psi (21.7 bar) fluid pressure. Its stainless steel construction ensures durability and resistance to corrosive material exposure. The pump features Graco’s proven Merkur air-motor with pilot-valve technology, eliminating mechanical reversing components and reducing maintenance cycles. Compared to its predecessor (the T2 pump), the T3 is approximately 3 × quieter and stands 3.7 in (9.4 cm) shorter above the drum, improving maneuverability inside spray rig setups. Every unit includes a fluid supply kit and air hose kit to facilitate installation and operation. Ideal for industrial spray applications, this pump delivers reliable flow and rugged construction to support demanding jobs.

Frequently Asked Questions

Service & Support

Can the pump handle high-viscosity foams and polyureas?

Yes the T3 pump is designed for A and B materials used in foam and polyurea spray systems and holds a high fluid pressure rating of 315 psi.

What makes the T3 pump better than earlier models?

The Merkur air-motor uses pure pneumatic switching (pilot-valve) which eliminates the mechanical reversing mechanism found in earlier pumps, reducing wear and parts count.

Will the T3 pump fit easily in tight drum-available spaces?

Yes — the T3 is 3.7 in (≈9.4 cm) shorter above the drum than the older T2 design, making drum removal and installation easier in compact rigs.
