Big Hole SH300A3 Excavator Hydraulic Axial Piston Pump K5V140DTP-9N0A

Big Hole SH300A3 Excavator Hydraulic Axial Piston Pump K5V140DTP-9N0A

1. "Big Hole" Design for Enhanced Flow

• Expanded inlet/outlet ports (referred to as "Big Hole") reduce pressure loss and improve oil flow efficiency, enabling higher output with lower energy consumption .

• 140 cc/rev displacement (typical for K5V140 series) ensures consistent power delivery for heavy loads, while variable displacement technology adjusts flow (up to 150 L/min) and pressure in real time, optimizing energy efficiency by up to 15% .

2. Heavy-Duty Compatibility

• Direct fit for SH300A3 excavators: Features a 16-tooth gear and 6-hole mounting flange that precisely match the drivetrain, eliminating modification needs and ensuring plug-and-play installation .

• Engineered to replicate the performance characteristics of original pumps, including pressure response and flow control, for consistent operation across brands like Kobelco, Hyundai, and Volvo .

3. Advanced Hydraulic Control

• Total Power Control balances output between dual pumps to prevent engine overload during simultaneous tasks like digging and swinging .

• Negative Flow Control automatically reduces pump output when hydraulic demand decreases, enhancing responsiveness and reducing heat buildup .

• Speed-Sensing Control adjusts flow based on engine speed, ensuring smooth operation across varying workloads.

Quality Assurance

• Manufactured to ISO 9001 standards for consistent performance and reliability.

• Available as remanufactured units offering cost savings without compromising OEM-grade quality.

• Backed by a 6-12 month warranty on remanufactured pumps, covering defects in materials and workmanship.
