Gear Pump JD132091 is a critical hydraulic pressure supply component exclusively designed for Hydraulic Rock Drills. It excels in harsh mining environments—for instance, underground hard rock mines, high-altitude quarries, tunnel construction sites and continuous drilling areas with heavy load demands.
These settings pose unique challenges for gear pumps: frequent pressure fluctuations, abrasive hydraulic oil contaminants, high-speed operation (up to 2800rpm), vibration, and temperature swings. These issues often cause pump leakage, low efficiency, gear wear, or noise pollution, leading to drill hydraulic system failure and costly downtime. Yet, Gear Pump JD132091 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its cast iron housing + precision ground gear set withstands 25MPa rated pressure and 50MPa burst pressure. This eliminates pump rupture or internal leakage caused by pressure spikes in drill hydraulic systems. Second, the 92% volumetric efficiency delivers stable flow rate for drill actuation. Consequently, it improves drill operational efficiency by 20% compared to standard gear pumps. Third, the anti-leak double mechanical seal blocks oil leakage even at high pressure. Likewise, this reduces hydraulic oil loss and environmental contamination in mining sites.
Fourth, the precision gear meshing design minimizes operation noise (≤65dB at 1800rpm), complying with mining safety noise standards. Above all, this protects worker hearing and reduces on-site noise pollution. Fifth, the wide temperature adaptability (-20°C~100°C) ensures reliable operation in cold high-altitude mines and hot underground drilling environments. On top of that, the anti-wear gear coating (nitriding treatment) extends service life by 140% in contaminated hydraulic oil.
Unlike ordinary industrial gear pumps, this model is engineered for Hydraulic Rock Drills’ dynamic working conditions. To elaborate, the cast iron housing provides superior shock resistance, while the precision gear set matches the drill’s high-pressure flow requirements. Thus, it outperforms generic pumps in service life by 150%, significantly reducing replacement-related downtime.
Our manufacturing team uses precision gear hobbing + nitriding treatment technology for the gear set. Furthermore, each unit undergoes 25MPa pressure testing (30 minutes) and efficiency verification. Additionally, the pump undergoes 1000-hour continuous operation trials to ensure no performance degradation.
Notably, it adapts to extreme temperatures from -20°C (high-altitude cold regions) to 100°C (high-load drill hydraulic systems). Moreover, the cast iron housing passes 300-hour salt spray tests with no rust or corrosion. In addition, the mechanical seal endures 5000-hour oil immersion trials without leakage.
The pump’s standard flange connection design integrates seamlessly with mainstream Hydraulic Rock Drill hydraulic systems. It requires no modifications to existing pipelines or motors for installation. As a result, maintenance teams can complete replacement in 20 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform pressure resistance tests, efficiency inspections, noise measurement trials and leak verification. Importantly, it complies with ISO 4405 international hydraulic gear pump standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces pump-related failure rates by 93%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 57%.
It not only ensures stable hydraulic pressure supply for drill operations but also extends the service life of drill hydraulic systems by 85%. Overall, Gear Pump JD132091 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it minimizes downtime caused by pump failure, maximizing operational efficiency and project profitability.
