Product Introduction

Our Epiroc pump parts lineup encompasses all critical wear, mechanical, and control components for the complete Epiroc hydraulic pump system, including EZ-rolling sleeves for drill string compatibility, speed reducer assemblies, high-performance main pump mechanical seals, double/feeding pump cartridges, precision bearings, precision shafts, servo/balance control modules, and wear rings/plates. Crafted from high-grade hardened steel, wear-resistant alloys, oil-resistant elastomer seals, and precision-machined components, each part undergoes pressure testing, wear verification, and dimensional inspection to match Epiroc OEM performance standards. This comprehensive selection supports full pump overhauls, targeted seal/bearing replacements, and control system repairs, making it the definitive sourcing solution for Epiroc drilling pump maintenance.
Functional Capabilities
- Leak-Free Hydraulic Sealing: Main pump mechanical seals and precision wear rings create tight, durable seals, eliminating hydraulic fluid loss and maintaining stable system pressure.
- Smooth Power Transmission: Speed reducer systems and precision shafts ensure efficient power delivery to pump components, reducing energy loss and operational vibration.
- Stable Hydraulic Delivery: Double/feeding pump cartridges and servo/balance control modules regulate fluid flow and pressure, ensuring consistent pump performance during drilling operations.
- Wear Resistance & Longevity: High-precision bearings and wear plates absorb friction and impact, extending the service life of critical pump components.
- Drill Compatibility: 9″/9-7/8″/10-5/8″ EZ-rolling sleeves enable seamless compatibility with multiple drill string sizes, supporting versatile drilling operations.
- Precision Control: Servo and balance control modules fine-tune pump operation, preventing pressure spikes and ensuring stable hydraulic output.
Structural Design Features
- Exact Epiroc OEM Fit: Precision-machined dimensions and OEM part number matching ensure seamless replacement, cutting on-site installation time by up to 50%.
- High-Wear Material Construction: Hardened steel bearings, wear-resistant alloy plates, and high-grade elastomer seals resist abrasion and degradation from hydraulic fluids.
- Precision Machining Tolerances: Critical components are machined to ±0.001 inch tolerances, ensuring perfect alignment and eliminating premature wear.
- Modular Repair Design: Individual seals, bearings, cartridges, and control modules enable targeted repairs, minimizing part waste and lowering long-term maintenance costs.
- Wide Compatibility: Designed for all Epiroc drilling rig pump systems, supporting main pumps, double pumps, and feeding pumps across the brand’s equipment lineup.
Applicable Operating Conditions
These Epiroc pump components are engineered to perform reliably in rigorous drilling and mining scenarios, including:
- Epiroc drilling rig main hydraulic pumps, double pumps, and feeding pumps
- Onshore/offshore drilling, mining, and exploration operations with high-cycle pump usage
- High-pressure hydraulic systems with continuous fluid delivery requirements
- Harsh environments with abrasive drilling fluids, dust, and heavy vibration
- Routine pump maintenance, emergency field repairs, and full pump overhauls
Maintenance & Service Recommendations
- Inspect main pump mechanical seals and wear rings every 2000 operating hours for wear, swelling, or cracking; replace components during scheduled pump overhauls.
- Lubricate feeding/double pump bearings with approved high-temperature hydraulic grease every 1500 hours to prevent dry start wear and premature failure.
- Check pump cartridges and shafts for scoring or deformation quarterly, replacing worn components to maintain consistent hydraulic flow and pressure.
- Calibrate servo and balance control modules annually to ensure accurate pressure regulation and stable pump performance.
- Inspect EZ-rolling sleeves for wear or damage during drill string maintenance, replacing worn sleeves to preserve drill compatibility and smooth operation.
- Store elastomer seals and precision bearings in a cool, dry, dust-free environment to prevent premature degradation and contamination.

Field Failure Repair Case Studies
Case 1: Epiroc Main Pump Hydraulic Leakage
An Epiroc main pump experienced severe hydraulic fluid leakage due to a worn mechanical seal (2652154515). Installing a new OEM-matched mechanical seal eliminated leaks and restored full pressure retention.
Case 2: Feeding Pump Bearing Premature Failure
A feeding pump suffered catastrophic bearing failure, causing pump seizure and halting drilling operations. Replacing the worn feeding pump bearing (2657061715) restored smooth pump rotation and stable fluid delivery.
Case 3: Double Pump Pressure Loss
A double pump experienced consistent pressure loss due to a damaged cartridge (2657033011). Fitting a new double pump cartridge resolved pressure drops and restored consistent hydraulic performance.
