Informações detalhadas

1. Principais recursos e benefícios

• Genuine Kawasaki KPM main hydraulic pump – OEM part number 603555586. 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.

• Engineered for SANY SY480 and SY550 large excavators – Specifically designed for the 48–55‑ton class SY480 and SY550 excavators. This pump powers the boom, arm, bucket, swing, and travel circuits, delivering the massive flow and high pressure required for heavy mining, quarrying, and large‑scale earthmoving operations.

• 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. This optimizes energy efficiency, reduces fuel consumption, and delivers smooth, responsive control in all operating conditions.

• High‑pressure capability for 48–55‑ton class machines – Rated for continuous pressures up to 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, swing torque, and travel power hour after hour in the most demanding applications.

• Advanced control options – The pump supports multiple control methods including load sensing and pressure cut‑off, responding to mechanical, hydraulic, or electrical input signals. This provides precise, predictable machine response – critical for precision grading, trenching near utilities, and fine attachment control.

• Exceptional durability and contamination resistance – Designed with anti‑contamination features and robust construction for long service life even in harsh operating environments. Proper hydraulic fluid contamination control is essential to prevent premature wear and extend working life.

• Low noise and high efficiency – Kawasaki KPM pumps are known for high efficiency, low noise, energy savings, and long service life. The compact design delivers reliable performance while minimizing operational noise.

• Direct bolt‑on replacement for SY480 / SY550 – 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.

• Verificação visual pré-envio – 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. Aplicativos

The genuine Kawasaki KPM main hydraulic pump (603555586) is the power source for SANY SY480 and SY550 excavators used in the most demanding heavy industries:

• Mineração a céu aberto de grande escala – 48–55‑ton excavators are the backbone of copper, gold, iron ore, and coal mining operations. The pump’s variable displacement technology provides the massive flow needed for fast loading cycles 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 in remote mine sites where reliability is critical.

• Pedreiras e agregados – Loading trucks, stockpile management, and material handling in granite, limestone, and basalt quarries. The pump’s contamination‑resistant design withstands abrasive dust conditions, while the load‑sensing control provides smooth, responsive operation for precise bucket control.

• Construção pesada e infraestrutura – Dam building, highway cuts, tunnel portals, bridge footings, and large‑scale earthmoving projects. The pump’s ability to maintain consistent flow under varying loads ensures the excavator performs reliably throughout long shifts in exposed conditions.

• Demolição e processamento de sucata – 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 anti‑contamination features absorb these extreme conditions without premature wear.

• Manutenção de frotas de equipamentos para aluguel – 48–55‑ton excavators are high‑value rental assets. A genuine new pump provides predictable service life and eliminates the gamble of remanufactured or used units – avoiding costly mid‑rental failures, towing bills, and customer complaints.

• Energy & power generation projects – Pipeline construction, power plant earthmoving, and wind farm access road development. The pump’s high efficiency and low noise operation are advantageous in environmentally sensitive or noise‑restricted areas.

3. FAQ - Perguntas frequentes

Q1: Is this pump an exact replacement for my SANY SY480 or SY550?
A: Yes. The 603555586 is the genuine Kawasaki KPM main hydraulic pump for SANY SY480 and SY550 excavators. To confirm compatibility for your specific machine variant, send us your machine serial number and a photo of the old pump nameplate – we will verify within 2 hours.

P2: Esta é uma bomba nova ou uma unidade remanufaturada?
R: É nova / original genuína, not remanufactured. All internal components are new. The pump is manufactured by Kawasaki Precision Machinery (KPM) to original specifications and meets all OEM performance standards. KPM is one of the world’s leading suppliers of hydraulic pumps and motors for excavators, with over 95 years of hydraulic industry experience.

Q3: What is the warranty on this pump?
A: Warranty period is 6 to 12 months depending on product details. Não fornecemos serviço de garantia para peças originais genuínas. 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.

Q4: What are the key specifications of this pump?
A: This is a variable displacement axial piston swash plate pump rated for continuous pressures up to 34.3 MPa (≈4,975 psi) and peak pressures up to 39.2 MPa (≈5,685 psi). It supports multiple control options including load sensing and pressure cut‑off, and is designed for high efficiency, low noise, and long service life.

P5: Quanto tempo leva para a entrega?
A: Delivery is 1–3 working days after order confirmation from our Guangzhou warehouse. Express shipping (DHL/FedEx/UPS) is available for urgent orders.

P6: Quais formas de pagamento vocês aceitam?
A: We accept T/T (wire transfer), XTransfer, and Western Union.

Q7: How can I verify the pump is genuine before shipping?
R: Antes da embalagem, enviamos fotografias claras e de alta resolução da unidade real – flange de montagem, estrias, roscas das portas, marcas de fundição e condição geral. Você aprova o envio somente após revisar essas imagens. Nunca enviamos às cegas.

P8: Qual óleo devo usar com esta bomba?
A: Use a mineral oil‑based anti‑wear hydraulic fluid as recommended by Kawasaki. Proper hydraulic fluid contamination control is essential to prevent premature wear and extend the pump’s working life. Always refer to your SANY SY480 / SY550 operator’s manual for the correct viscosity and specification.
