Kawasaki KPM Main Hydraulic Pump for CAT336 Excavator – Genuine New

1. Características y ventajas principales

• 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 MPa (≈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.

• Reemplazo directo atornillable – 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.

• Verificación visual previa al envío – 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.

• Entrega rápida – 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. Aplicaciones

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.

• Canteras y áridos – 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.

• Apoyo minero – 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.

• Demolición y procesamiento de chatarra – 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.

• Flota de alquiler de equipos – 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.

• Silvicultura y desmonte de terrenos – 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:
– Los La línea de drenaje de la carcasa debe estar sin restricciones. Un drenaje bloqueado reventará el sello del eje instantáneamente en el primer arranque. debe estar despejado y sin restricciones. Un drenaje de carcasa bloqueado o doblado acumulará contrapresión dentro de la carcasa de la bomba y romperá el sello del eje instantáneamente en el primer arranque.
– Antes de instalar la bomba nueva, lave todo el sistema hidráulico y reemplace todos los filtros. Los contaminantes de una bomba averiada destruirán una bomba nueva tan rápido como una vieja: los residuos no discriminan.
– Use juntas tóricas y arandelas de sellado nuevas en cada conexión hidráulica. Los sellos reutilizados garantizan fugas.
– 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.
– Verifique la alineación de la bomba con la carcasa del volante del motor; la desalineación causa desgaste prematuro de los cojinetes y fuga del sello del eje.

Nota de garantía: Warranty period is 6 to 12 months depending on product details. No proporcionamos servicio de garantía para piezas originales genuinas. 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.
