Kawasaki KPM Main Hydraulic Pump for CAT336 Excavator – Genuine New

1. प्रमुख विशेषताएँ और लाभ

• Genuine Kawasaki KPM hydraulic pump – Manufactured by Kawasaki Precision Machinery (KPM), a global leader in hydraulic components for heavy equipment. This is a brand‑new, factory‑fresh unit – not remanufactured, not rebuilt. Kawasaki has been a trusted OEM supplier to Caterpillar for decades, and this pump is built to the same specifications as the unit that left the factory on your CAT336.

• Engineered specifically for CAT336 series excavators – Designed for CAT336, CAT336D, CAT336D2, CAT336GC, CAT336E, and related 33–36‑ton class excavators. The pump powers the boom, arm, bucket, swing, and travel circuits with the precise flow and high pressure required for heavy construction, quarrying, and mining operations.

• Kawasaki K5V / K7V series heavy‑duty platform – Depending on the specific CAT336 variant, this pump is available in the K5V160DP, K5V200DP, or K7V series configurations. The K5V series is the proven successor to the widely used K3V platform, featuring higher power density, improved efficiency, and reduced noise – up to 1.5 percentage points better efficiency and 3 dB(A) lower noise than earlier generations. The K7V series offers a step change in hydraulic pump efficiency for the most demanding applications.

• High‑pressure capability for 33‑ton class work – Rated for continuous operating pressure of 34.3 兆帕（约 4,975 psi） with peak pressure capability up to 39.2 MPa (≈5,685 psi) . This pressure capability delivers consistent digging force (over 200 kN), swing torque, and travel power hour after hour in the most demanding applications.

• Variable displacement axial piston design – Features a swash plate type axial piston pump with variable displacement technology that automatically adjusts flow to match actual working demand. The nominal displacement ranges from 160 cm³/rev to 200 cm³/rev depending on the specific model. This optimizes energy efficiency, reduces fuel consumption, and delivers smooth, responsive control in all operating conditions.

• Kawasaki‘s proven reliability and durability – Known worldwide for high efficiency, low noise, energy savings, long service life, and precise control. The pump is designed with robust construction and contamination resistance for long service life even in harsh operating environments. Kawasaki’s K3V/K5V series are the most common hydraulic pumps for excavators, with a well‑established reputation in the industry.

• Multiple control options – The pump supports various control methods and is capable of responding to either mechanical, hydraulic, or electrical input signals. This provides precise, predictable machine response – critical for precision grading, trenching near utilities, and fine attachment control.

• 直接螺栓固定替换 – Mounting flange, drive shaft spline, and hydraulic port configurations match the original Kawasaki KPM specifications exactly. No modifications, no adapters – your mechanic unbolts the old pump and bolts this one in.

• 发货前可视化确认 – Before packing, we send you detailed high‑resolution photographs of the actual unit (mounting flange, splines, port threads, castings, overall condition). You approve shipment – we never ship blind.

• त्वरित डिलीवरी – 1‑3 working days lead time from our Guangzhou warehouse. Monthly supply capacity of 1,000 units, available for single‑piece or bulk orders.

2. अनुप्रयोग

The genuine Kawasaki KPM main hydraulic pump is the power source for CAT336 series excavators used in the most demanding job sites:

• Large‑scale construction & infrastructure – Highway excavation, dam building, bridge footings, and large‑scale earthmoving projects. The pump‘s variable displacement technology provides the flow needed for fast cycle times while automatically reducing flow during lighter work to save fuel. The high‑pressure capability (34.3 MPa) delivers consistent digging force and swing torque hour after hour.

• 采石与骨料生产 – Loading trucks, stockpile management, and material handling in granite, limestone, and basalt quarries. The pump’s robust construction and contamination‑resistant design withstand abrasive dust conditions, while the load‑sensing control provides smooth, responsive operation for precise bucket control.

• 矿山辅助作业 – Site cleanup, road maintenance, drainage works, and equipment pad grading. A genuine new pump with zero hours and factory tolerances provides predictable service life (typically 6,000–8,000 hours) – avoiding costly unplanned downtime in remote mine sites.

• 拆除与废料处理 – Shock loads, vibration, and sharp debris are routine in demolition yards and metal recycling facilities. The Kawasaki KPM pump’s robust cast iron construction and high‑pressure peak capability absorb these extreme conditions without premature wear.

• 设备租赁车队 – 33‑ton excavators are high‑value rental assets. A genuine new pump eliminates the gamble of remanufactured or used units, offering predictable performance and reliability that keeps your machine on rent, not in the shop.

• 林业与土地清理 – Steep slopes, fallen timber, and uneven terrain demand reliable hydraulic performance. The integral control system prevents engine stall under sudden load spikes, maintaining consistent power for saws, grapples, and mulchers.

Critical installation tip for the CAT336 main pump:
– 壳体泄油管路 必须畅通无阻。堵塞或扭结的泄油管会在泵壳内产生背压，并在首次启动时立即损坏轴封.
– 在安装新泵之前，请冲洗整个液压系统并更换所有滤芯。来自故障泵的污染物会像损坏旧泵一样迅速地毁坏新泵——碎屑不分新旧.
– 在每个液压连接处使用新的 O 型圈和密封垫圈。重复使用密封件必然导致泄漏。.
– After installation, run the engine at low idle for 2‑3 minutes with the pump in neutral, then slowly cycle each function (boom, arm, bucket, swing, travel) to purge air from the system.
– 检查泵与发动机飞轮壳的对中情况——不对中会导致轴承过早磨损和轴封泄漏.

保修说明： Warranty period is 6 to 12 months depending on product details. 我们不提供原装正品零件的保修服务。. Our value is delivered up front: genuine Kawasaki KPM components, new‑condition pump, and pre‑shipment visual verification. For customers who require a warranty‑covered option, we can quote aftermarket alternatives – ask our sales team.

The main hydraulic pump is the heart of your CAT336‘s hydraulic system. A genuine new Kawasaki KPM pump from Hongtengda Parts delivers the reliability and performance your 33‑ton excavator demands – not with worn components disguised as “rebuilt”, but with factory‑fresh Japanese engineering.
