   And first—thank you so wholeheartedly, from the bottom of our hearts, for choosing SPARKLING MACHINERY’s KBJ12130 Main Pump for your Case CX290B excavator! Your trust fuels our unwavering commitment to Case’s strict hydraulic system standards. 
   This main pump is your excavator’s "hydraulic power backbone"; a faulty one risks weak actuator movement, uneven operation, or unexpected system breakdowns. Ours matches Case’s original specifications perfectly—you can depend on it fully. Let’s explore why it’s the ideal fit for your machine.

   Why choose the SPARKLING NEW CX290B KBJ12130 Main Pump?
   - Direct-fit compatibility: Custom-engineered to match Case CX290B’s hydraulic system interfaces, mounting brackets, and drive connections. Marked with part number KBJ12130, it aligns seamlessly with existing hydraulic setups—no modification, adapter use, or circuit adjustments required. Cuts replacement downtime by 36%, getting your Case CX290B back to heavy-duty operation faster.
   - Precision control: Features ultra-accurate pressure regulation (deviation <1.2% from Case’s rated specs) and consistent flow output (no sudden drops), maintaining hydraulic pressure within the 38-42MPa optimal range. Ensures reliable performance for mining-site heavy loads or construction-site high-intensity excavation—to avoid operational inefficiencies.
   - Rigorous quality: Undergoes 28+ strict quality tests—including high-pressure durability (45MPa for 2,500+ hours without leakage), high-low temperature cycles (-30°C to 100°C, 1,200+ cycles), wear resistance (4,000+ working hours), and impact resistance (1,000N impact without structural damage). Withstands dusty construction/mining environments, mechanical vibration, and hydraulic shock without component failure or seal leakage.
   - Professional support: Backed by a dedicated team with deep expertise in Case CX290B hydraulic systems. Offers 7×24 online assistance, including step-by-step installation guides (mounting torque charts, oil filling tips), maintenance recommendations (filter replacement intervals, hydraulic oil grade checks), and troubleshooting for low pressure or abnormal noise. Average response time <2 hours.
   - Cost-effective reliability: Delivers Case OEM-level hydraulic performance at a competitive price. High-strength rotor components and wear-resistant seals extend service life by 72% compared to generic pumps, reducing long-term replacement costs by 43%. Minimizes unplanned downtime from hydraulic system failures—preventing costly project delays or equipment damage.
