Informações detalhadas

1. Principais recursos e benefícios

• Genuine Kawasaki KPM hydraulic pump – OEM part number 627-1299 (also referenced as 6271299). 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 CAT349C.

• Engineered specifically for CAT349C series excavators – Designed for CAT349C, CAT349D, CAT349E, and related 45–50‑ton class excavators. The pump powers the boom, arm, bucket, swing, and travel circuits with the precise flow and high pressure required for heavy mining, quarrying, and large‑scale earthmoving operations.

• Kawasaki K5V series heavy‑duty platform – 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. This translates directly to lower fuel consumption and quieter operation on your job site.

• High‑pressure capability for 45‑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, swing torque, and travel power hour after hour in the most demanding applications – essential for a 45‑ton class machine working in hard rock and heavy overburden.

• 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 is 212 cm³/rev, delivering a maximum flow of approximately 212 L/min from each of its two main sections. This optimizes energy efficiency, reduces fuel consumption, and delivers smooth, responsive control in all operating conditions.

• Twin‑pump configuration – Two independent pump sections in one housing allow you to travel while booming up, or swing while curling the bucket, without one function robbing power from the other. This is critical for the CAT349C’s multi‑function operations – keeping cycle times short and productivity high.

• 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.

• Substituição direta do tipo "aparafusar e usar" – 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 (627-1299) is the power source for CAT349C series excavators used in the most demanding job sites:

• Mineração a céu aberto de grande escala – 45‑ton excavators are the backbone of copper, gold, iron ore, and coal mining operations. The pump’s 212 L/min flow and 34.3 MPa pressure capability deliver fast loading cycles and consistent digging force hour after hour in remote mine sites where reliability is critical. A genuine new pump with zero hours and factory tolerances provides predictable service life – avoiding costly unplanned downtime.

• Pedreiras e agregados – 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 twin‑pump configuration 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 high‑pressure peak capability absorb these extreme conditions without premature wear.

• Frota de aluguel de equipamentos – 45‑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.

• 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.

Critical installation tip for the CAT349C main pump:
– Os A linha de dreno do cárter em cada bomba deve estar desobstruída e sem restrições. Um dreno do cárter bloqueado estourará o selo do eixo instantaneamente na primeira partida. deve estar limpa e sem restrições. Uma drenagem da carcaça bloqueada ou dobrada criará contrapressão dentro do alojamento da bomba e romperá o selo do eixo instantaneamente na primeira partida.
– Antes de instalar a nova bomba, lave todo o sistema hidráulico e substitua todos os filtros. Contaminantes de uma bomba com falha destruirão uma bomba nova tão rapidamente quanto uma antiga – os detritos não discriminam.
– Após a instalação, opere o motor em marcha lenta baixa por 2 a 3 minutos com as bombas em neutro, em seguida, acione lentamente cada função (lança, braço, caçamba, giro, deslocamento) para purgar o ar do sistema.
– 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 o alinhamento da bomba com o alojamento do volante do motor – o desalinhamento causa desgaste prematuro do rolamento e vazamento do selo do eixo.
