803432432 Key Features
- High-Pressure, Durable Design
Rated pressure of 350 bar and peak pressure of 400 bar, it meets the high-pressure requirements of percussion drilling and rotary drives. The one-piece cast iron housing has been optimized using finite element methods for impact and deformation resistance. - High-Precision, Wear-Resistant Gears
The involute gears are made of 20CrMnTi alloy steel, carburized and hardened (HRC58-62), and then treated with a DLC coating, increasing wear resistance by three times, reducing wear caused by particle contamination during drilling. - Dual-Layer Seal Protection
The shaft seal utilizes a silicon carbide (SiC) mechanical seal and a fluororubber O-ring, while the end cap seal utilizes a metal gasket and oil-resistant rubber, achieving an IP67 rating and preventing the intrusion of mud and dust during drilling operations. - Wide Temperature Adaptability
Low-Temperature Startup: The bearings are pre-coated with low-temperature grease, enabling normal startup at -30°C, preventing cold start jams in polar regions or winter conditions.
High-Temperature Resistance: The seals are compatible with oil temperatures up to 120°C, enabling continuous operation of the drilling rig.
803432432 Core Advantages
- Efficient and Stable OutputVolume efficiency ≥ 92% and flow pulsation ≤ 3% ensure smooth operation of the drill rig’s rotary mechanism, reduce drill pipe vibration, and improve drilling accuracy.
- Long Life and Low Maintenance
Gear life exceeds 10,000 hours, and the bearings utilize a double-row tapered roller design (L10 life ≥ 20,000 hours), reducing rig downtime and replacement frequency, lowering overall lifecycle costs. - Strong Contamination Resistance
A large oil intake (≥ 18mm) reduces oil cleanliness requirements (stable operation within NAS Class 10), making it suitable for field drilling environments and reducing failures caused by impurities. - Modular and Quick Replacement
Compliant with ISO 3019-2 standard flange connections, it can quickly replace existing pumps on XCMG drilling rigs of the same series (such as the XR series rotary drilling rigs), shortening maintenance time and improving uptime.
