Kawasaki KPM Main Hydraulic Pump for CAT336 Excavator – Genuine New

1.主な特徴と利点

• カワサキ純正 KPM 油圧ポンプ – 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 – 連続使用圧力の定格は 34.3 MPa（約4,975 psi） 最大許容圧力は 39.2 MPa（約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.

• 可変排量軸方向ピストン構造 – 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.

• 多彩な制御オプション – このポンプはさまざまな制御方式に対応しており、機械式、油圧式、電気式のいずれの入力信号にも応答可能です。これにより、正確かつ予測可能な機械の応答が実現され、これは精密な整地作業、公共設備付近での溝掘り作業、およびアタッチメントの微細な制御において極めて重要です。.

• 直接ボルトオン交換 – 取り付けフランジ、ドライブシャフトのスプライン、および油圧ポートの仕様は、純正のカワサキKPM仕様と完全に一致しています。改造もアダプターも不要です。整備士が古いポンプを取り外し、このポンプをボルトで取り付けるだけです。.

• 出荷前の目視確認 – 梱包前に、実際の製品（取付フランジ、スプライン、ポートのねじ山、鋳造部、全体的な状態）の詳細な高解像度写真をお送りいたします。お客様にご承認いただいた上で出荷いたします。確認なしに発送することは決してありません。.

• 迅速な配達 – 広州の倉庫からの出荷まで、1～3営業日かかります。月間供給能力は1,000台で、1個からの注文から大量注文まで承ります。.

2.アプリケーション

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.

• 採石及び骨材 – 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.

• 鉱山支援 – 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.

• 解体・スクラップ処理 – 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.

• 機器レンタル事業者様向け – 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.

• 林業・土地開墾 – 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:
– ケースドレンライン は、クリアで障害がない状態でなければなりません。ケースドレンが詰まったり屈曲したりすると、ポンプハウジング内に背圧が発生し、初回起動時に即座にシャフトシールが破損します。.
– 新品ポンプを取り付ける前に、油圧システム全体をフラッシングし、すべてのフィルターを交換してください。故障したポンプからのコンタミネーションは、古いポンプと同様に新品ポンプもすぐに破壊します – 異物は区別しません。.
– すべての油圧接続部に新品のOリングとシールワッシャーを使用してください。シールの再使用は漏れの原因となります。.
– 取り付け後、ポンプをニュートラルにした状態でエンジンを低回転で2～3分間空転させ、その後、各機能（ブーム、アーム、バケット、旋回、走行）をゆっくりと動作させて、システム内の空気を抜いてください。.
– ポンプとエンジンフライホイールハウジングの芯合わせを確認してください – 芯ずれはベアリングの早期摩耗とシャフトシールからの漏れの原因となります。.
