SPARKLING High-Pressure Pump

The Sparkling Machinery A2FM23 Hydraulic Pump (model R902201557) is a high-performance axial piston pump in fixed-displacement design, engineered for both open- and closed-circuit hydraulic systems like Rexroth’s A2FM23 range. Rated up to 400 bar nominal pressure (max. 450 bar), this pump delivers strong torque and stable flow under heavy-duty excavation scenarios. Featuring a compact bent-axis construction, it offers high power density and efficient operation in both mobile and stationary applications. It’s ideal for excavators, construction machinery, and industrial hydraulic systems requiring reliable, OEM-compatible performance.

   SPARKLING MACHINERY NEW 301.5 302.5 303 303.5 156-8847 Solenoid is a dedicated electrical control component for CATERPILLAR 301.5, 302.5, 303, and 303.5 mini crawler excavators (versatile for landscaping, indoor demolition, and small-scale construction). As a key switch for the excavator’s hydraulic or fuel systems, it converts electrical signals into mechanical action to control valve opening/closing, ensuring precise operation of functions like bucket tilting and arm movement during delicate tasks.
   Meeting CATERPILLAR OEM standards (part no. 156-8847), it endures -30°C to 85°C temperatures, resists vibration and electrical interference, and maintains stable switching performance. Strict testing guarantees seamless compatibility and long-term reliability for the four CATERPILLAR models.

   SPARKLING MACHINERY NEW ISX15 CM2350 X101 4307226 Relief Valve is a dedicated, high-pressure safety component exclusively engineered for CUMMINS ISX15 (CM2350, X101) engine-equipped excavators—heavy-duty equipment widely used in large-scale mining, construction, and infrastructure projects. As the core safety guard of the excavator’s engine or hydraulic system, it precisely limits maximum pressure, preventing overload damage to critical components (e.g., fuel injectors, hydraulic pumps) during high-intensity tasks like rock breaking, bulk ore loading, and deep excavation. This function is vital for maintaining system stability, avoiding costly component failures, and ensuring uninterrupted operation of CUMMINS-powered excavators.

   Engineered to meet CUMMINS’ original equipment (OEM) standards and marked with the genuine part number 4307226, the Relief Valve withstands harsh working conditions: high operating pressure (up to 35 MPa), extreme temperature fluctuations (-30°C to 110°C), and continuous vibration from heavy-duty use. It resists oil contamination and mechanical wear, providing long-lasting pressure regulation reliability for CUMMINS ISX15 (CM2350, X101) engine excavators. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for daily high-load tasks.

The CA1878636 Main Control Valve Assembly (also referenced as 187-8636 or 1878636) is an essential hydraulic component designed specifically for the Caterpillar D9R track-type tractor. This unit is responsible for the precise distribution and regulation of hydraulic flow, enabling smooth and accurate control of blade, ripper, and other operational functions.

Key Features:

• Direct-fit replacement for CAT D9R – no modification required

• OEM-standard internal machining ensures optimal hydraulic flow and durability

• High-pressure resistance for demanding dozer applications

• Fully tested before delivery, ensuring performance and zero leakage

Whether you're maintaining a mining fleet or servicing a heavy-duty bulldozer, this main control valve assy ensures efficient operation and extended equipment lifespan.
