The Graco GT 750 36:1 Grease Transfer Pump features Graco's NXT air motor technology combined with its Fire-Ball pump design to deliver high flow rates at a low air-supply pressure. The large 7.5" air motor and pump lower combination allows this pump to move the same amount of grease with up to three to four times fewer pump strokes, according to the company. This helps improve seal life and reduces the likelihood of pump failure due to icing. This product is made in the U.S.A.
