Kawasaki K3V112DTP-9TEL Hydraulic Main Pump for Kobelco SK200-6E Crawler Excavator

Product Overview:
The K3V112DTP-9TEL is a high-performance swashplate design axial piston tandem (dual) pump from the renowned Kawasaki K3V series. Specifically engineered for open circuit hydraulic systems, this variable displacement double pump delivers exceptional power density, reliable operation, and precise control under extreme loads . With a total displacement of 112 cm³/rev (per pump) and robust construction, it provides stepless flow adjustment for demanding mobile applications. With over 25 years of proven field experience, the K3V series is recognized for its high reliability in the global construction machinery market . This unit is a direct, high-quality replacement solution for original Kawasaki equipment, specifically designed for Kobelco SK200-6E and SK230-6E excavators .

Core Features:

• Tandem / Dual Pump Configuration: Two high-performance pumps in a compact, space-saving tandem arrangement, providing independent hydraulic power for multiple machine functions (e.g., boom, arm, bucket, swing) from a single drive source. The two pumps share a common suction port but have independent delivery ports .

• PTO (Power Take-Off) Capability: The "P" in DTP indicates this model features a through-shaft PTO, allowing for the connection of additional hydraulic components such as pilot gear pumps, providing flexible system configuration options .

• Robust Swashplate Design: The proven swashplate design with cast iron construction ensures reliable operation, excellent volumetric efficiency (up to 95%), and long service life in open circuit applications. Advanced surface wear-resistant coating technology significantly extends the pump's service life .

• High-Pressure Capability: Delivers 32 MPa rated and 35 MPa peak pressure (approximately 320-350 bar), meeting the most demanding excavator and construction application requirements .

• Excellent Suction Characteristics: Superior self-priming performance (up to 2,200 rpm) ensures reliable operation even in demanding conditions and at higher speeds, minimizing cavitation risks .

• Multiple Control Options: Offers various control methods including negative flow control (standard for excavators), load sensing control, and total horsepower control, providing flexibility for different application requirements .

• Low Noise Operation: Unique design features significantly reduce pressure fluctuations that cause noise, ensuring quiet operation meeting stringent workplace noise regulations .

• Durability: High-quality materials and stringent quality control processes ensure long service life in demanding continuous operation. Hardened steel components and precision-machined parts withstand heavy loads and harsh environments .
