Denison Premier P260 Hydraulic Pump: Maximum Displacement for Large Rotary Drilling Rigs Rotary drilling rigs used for bridge piling, high-rise foundations, and deep excavation demand hydraulic systems that deliver enormous torque at low speeds while withstanding continuous high pressure. The Denison Premier P260 pump —also known as the Parker P260 hydraulic pump —is built for these extreme conditions. Available as P260H and P260Q , this pump features a massive displacement of 262.2 cm³/rev, continuous pressure up to 500 bar (7250 psi intermittent), and an optimized speed range of 1850–2100 rpm. It is the hydraulic heart that powers the largest rotary heads, crowd cylinders, and auxiliary circuits on Atlas Copco, Sandvik, and Epiroc drilling rigs. Technical Data – Denison Premier P260 Parameter P260H / P260Q Max. Displacement 262.2 cm³/rev Continuous Pressure 414 – 500 bar Intermittent Pressure 6000 – 7250 psi Speed Range @ Full Stroke 1850 – 2100 rpm Circuit Type Open circuit Warranty 12 months Technical PDF www.baolilai-pump.com/contact_us/ P260H optimized for 1850–2000 rpm (higher torque); P260Q for 2000–2100 rpm (higher flow) Why Rotary Drilling Rigs Need the P260 Massive Displacement for Low-Speed, High-Torque Rotation Large-diameter augers (up to 3 meters) require immense torque to penetrate hard clay, cobbles, or soft rock. The P260’s 262.2 cc/rev displacement delivers approximately 550–600 L/min at 2100 rpm, providing the rotational force needed without overspeeding the rotary head. The P260H variant is specifically calibrated for applications where torque is paramount, such as drilling through boulder beds. 500 Bar Continuous – No Pressure Drop Under Load When the rotary head encounters resistance or the crowd cylinder pushes the auger deeper, pressure can spike to 7250 psi. The gold cup rotating group—featuring a floating valve plate and hardened piston shoes—absorbs these shocks without internal leakage or housing distortion. This ensures consistent penetration rates and prevents costly stalling. Built for the Harshest Drilling Environments Explosion-proof: Spark-resistant internals and sealed housings meet ATEX/MSHA standards, safe for drilling near gas pockets or coal seams. Contamination defense: Double shaft seals keep abrasive drill cuttings, bentonite slurry, and groundwater out. Thermal stability: –30°C to 115°C range – reliable in freezing winters or desert heat.
