Sandvik HL1560T/HL1000/HL850S Drill Diaphragm | Long Hole Parts

The Sandvik HL1560T, HL1000, HL1000S, HL1010 and HL850S rock drill lineup is purpose-built for heavy-duty long-hole and large-diameter drilling, covering both open-pit surface mining and underground bulk blasting projects. Featuring independent rotation structures and separate flushing systems, these top hammer drills deliver powerful percussion output and stable deep-hole forming capacity, making them the core configuration for Sandvik Pantera series surface drilling rigs and underground long-hole drilling equipment. For heavy-load deep penetration operations, the rock drill diaphragm acts as a critical hydraulic protection component, sustaining system stability under extreme long-duration working loads.

Tailored for the high-power hydraulic circuit of Sandvik HL1560T, HL1000-series and HL850S drills, the professional Sandvik rock drill diaphragm features upgraded pressure-bearing and long-cycle fatigue resistance, different from standard precision or low-vibration diaphragms. As a core hydraulic long hole drill diaphragm, it undertakes continuous pressure stabilization and instantaneous peak pressure buffering during deep-hole drilling. It effectively balances hydraulic pressure output for independent rotation and percussion systems, prevents pressure deviation caused by long-hour operation, and isolates abrasive rock dust and drilling sludge from invading internal hydraulic components. This robust sealing performance eliminates common deep-drilling faults such as inconsistent hole depth, weakened deep-hole percussion force, and hydraulic system leakage.

Constructed with high-pressure resistant industrial rubber and thickened reinforced structure, this heavy-duty drill wear diaphragm adapts perfectly to the high-frequency, high-load working characteristics of large-aperture drilling equipment. The HL1560T model supports 89–152mm large-diameter hole drilling with 33kW high percussion power, while HL1000, HL1000S, HL1010 and HL850S models handle medium and large deep-hole mining tasks with stable high-output performance. Generic ordinary diaphragms are unable to withstand prolonged heavy percussion loads, easily causing bulging, cracking and elastic failure. The OEM-matched diaphragm maintains complete structural integrity and stable sealing performance, ensuring continuous and efficient deep-hole drilling efficiency.

Scientific replacement of load-bearing wearing parts is essential for mining long hole drill maintenance in large-scale mining fleets. Most efficiency attenuation and unplanned shutdowns of Sandvik heavy-duty long-hole drills are caused by aging and fatigued diaphragms, which fail to stabilize hydraulic pressure under deep-drilling loads. Timely upgrading to high-performance heavy-duty diaphragms restores the drill’s rated percussion power and deep-hole penetration capacity, reduces repeated drilling operations and equipment maintenance frequency, and significantly improves the overall productivity of open-pit and underground mining projects.
