KYB PSVD2-42 Hydraulic Main Pump – Genuine Japanese for Sunward 100 / HTT 85 Excavators

Description

Detail Information

1. Key Features & Benefits

• Genuine KYB Japan hydraulic pump – Model PSVD2-42 (OEM B0600-42001). Manufactured by KYB Corporation (formerly Kayaba), a world‑renowned Japanese hydraulic specialist and OEM supplier to leading excavator manufacturers including Kubota, Yanmar, Hitachi, and LiuGong. This is a brand‑new, factory‑fresh unit – not remanufactured, not a generic substitute.

• Engineered for 6–8 ton compact excavators – Designed specifically for Sunward SWE100, HTT 85 (Hengtian JV85), LiuGong CLG906, Kubota KX series, and related 6–8 ton class machines. This pump powers the boom, arm, bucket, swing, and travel circuits with the precise, responsive hydraulic flow required for demanding construction, utility, and earthmoving work.

• PSVD2 series – KYB’s proven 1C/B split flow pump platform – The PSVD2-42 is a split flow open pump developed by KYB as part of their 1C/B piston pump family for compact excavators. Unlike traditional tandem pumps that require two separate pump sections in a long housing, the 1C/B design integrates two discharge ports (P1 and P2) within a single compact body. The result: a 52% reduction in torque loss compared to existing products performing the same work, with shorter overall length, lower cost, and improved mountability.

• High power density in a compact size – The PSVD2-42 delivers substantial power output within a compact form factor, meeting the high power demands of construction machinery. With a displacement of approximately 42 cc/rev and a maximum pressure of 31 MPa (≈4,496 psi) , this pump provides the hydraulic muscle needed for continuous heavy‑duty operation.

• Variable displacement swash plate design – Features a swash plate axial piston structure with servo regulator control, which automatically adjusts displacement according to load. This matches engine power output, avoids overload, and achieves significant energy savings and efficiency gains.

• High‑pressure, durable construction – Core pressure‑bearing components (valve plate, slipper, cylinder block) use high‑strength wear‑resistant materials. Rated pressure of 25–28 MPa with maximum pressure reaching 31 MPa ensures reliable performance even in difficult terrain and climate conditions.

• Multi‑circuit capability – Integrated design supports multiple hydraulic actuators simultaneously – boom, arm, travel, swing, and hydraulic breaker can all be driven at once, meeting complex working demands. The split flow design discharges two independent flows from locations P1 and P2.

• Designed for deep excavation and easy maintenance – The pump is engineered for deep excavation work and is easy to disassemble and maintain for maximum efficiency. Standardised installation with direct connection to the engine flywheel housing ensures high coaxial drive efficiency and universal mounting interfaces.

• Wide excavator compatibility – The PSVD2-42 is designed to work with a wide variety of excavator models, including mini, medium, and heavy machines. Suitable for Kubota KX series, LiuGong CLG906, Sunward SWE100, HTT 85, and many other 6–8 ton class compact excavators.

• Replaces multiple OEM part numbers – Compatible with and replaces OEM part number B0600-42001 for Sunward and HTT excavators.

• Direct bolt‑on replacement – Mounting flange and hydraulic port configurations match the original KYB PSVD2-42 specifications exactly. No modifications, no adapters – your mechanic unbolts the old pump and bolts this one in.

• Pre‑shipment visual verification – 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.

• Fast delivery – 5–8 working days lead time from our Guangzhou warehouse. Monthly supply capacity of 300 units, available for single‑piece or bulk orders.

2. Applications

The genuine KYB PSVD2-42 hydraulic main pump is the power source for Sunward SWE100, HTT 85, and 6–8 ton class compact excavators used across a wide range of job sites:

• Urban construction & utilities – Sidewalk repairs, water and gas line trenching, fibre‑optic cable installation, and small‑scale demolition in tight access spaces. The pump’s compact 1C/B design, low torque loss, and precise flow control are essential for working near existing structures and utilities. The split flow architecture provides independent flow to separate circuits – travel and working functions operate simultaneously without power loss.

• Residential & commercial development – Foundation digging, basement excavation, retaining walls, grading, and site preparation. The pump’s smooth response, quiet operation, and variable displacement control minimise disturbance to nearby homes, while the high‑pressure capability (31 MPa) provides the power needed for attachments like augers and breakers.

• Quarrying & aggregates – Light to medium quarry work, stockpile management, and material handling in abrasive dust conditions. The pump’s robust construction, high‑strength wear‑resistant materials, and contamination‑resistant design withstand harsh operating environments.

• Agriculture & land management – Drainage ditch cleaning, irrigation trenching, pond maintenance, and fence post holes. The pump’s rated pressure of 25–28 MPa provides the attachment power needed for rippers and post‑hole augers, while the variable displacement control adapts to changing load conditions, improving efficiency and reducing fuel consumption in long‑duration agricultural work.

• Equipment rental fleet – 6–8 ton compact excavators are frequently rented machines. 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.

• Forestry & vegetation clearance – 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.

• Road & bridge maintenance – Shoulder repairs, guardrail replacement, and drainage cleaning. The pump’s responsive control allows operators to position attachments precisely for roadside work, even in tight work zones with limited space.
