- Reliable Grease Flow – A 76.2 mm (3″) differential air motor with a double-acting pump design ensures smooth, accurate grease dispensing.
- Heavy-Duty Durability – Thick cast aluminium air motor housing provides unmatched strength for demanding environments.
- Lower Maintenance Costs – Fewer moving parts in the air motor mean less downtime, fewer repairs, and reduced operating expenses.
- Extended Seal Life – In-line pump design keeps the air and fluid pistons aligned, maximising seal longevity.
- Minimised Downtime – Displacement rods are engineered with Graco’s proprietary process to reduce wear and extend service intervals.
- Superior Sealing – Non-metallic poppet valves maintain positive sealing, even in dirty air conditions, for long-term reliability.
- Reduced Icing – Large air porting improves compressed air efficiency, allowing continuous operation with less risk of icing.
- Corrosion-Resistant Build – Protected with liquid salt nitriding, nickel plating, stainless steel, aluminium, and chrome on key components for longer life.









Now that I’ve found Plantman and they’re local which is a bonus, I won’t need to look elsewhere. They also have an extensive range of equipment that suits our requirements for servicing the mining industry. I have no hesitation in recommending Plantman to any of our clients. Well Done!!!
