1. Product Overview

LD-PV270 is a heavy-duty open-circuit variable axial piston pump independently developed and manufactured by HYDSUNRIDA, specializing in industrial hydraulic pump domestic substitution. Featuring 270cc large displacement and ultra-high pressure resistance, this variable piston pump is professionally engineered for heavy-load industrial hydraulic systems, supporting 24-hour full-load continuous operation and high-frequency start-stop working cycles with stable and consistent performance.With ultra-low internal leakage, minimal flow fluctuation, low noise and outstanding energy efficiency, LD-PV270 supports 1:1 non-destructive OEM replacement of all mainstream 270cc imported and domestic piston pumps. All installation dimensions, flange specifications, oil port layout and core operating parameters fully match global universal standards. No oil circuit modification or system recalibration is required, effectively cutting equipment maintenance and hydraulic system upgrade costs for heavy industrial enterprises.

2. Authoritative Quality Certification & Strict Testing Process

All LD-PV270 series hydraulic pumps are manufactured under strict ISO9001:2015 Quality Management System and certified by SGS authoritative certification, complying fully with GB/T3766-2015 national hydraulic industry technical standards to ensure standardized and reliable product quality.Every unit undergoes four strict factory tests before delivery: ultra-high pressure resistance test, precise flow calibration test, sealing anti-leakage test and long-term full-load endurance running test. Full-range quality control eliminates defective products, guaranteeing excellent overload resistance, structural fatigue resistance and ultra-low failure rate for long-term extreme heavy-duty industrial operation.

4. Core Product & Service Advantages

4.1 1:1 Zero-Modification Replacement

LD-PV270 completely matches the global standard size and parameter system of 270cc piston pumps. It can directly replace imported and domestic equivalent models with zero modification, zero debugging and zero replacement threshold, solving the industry pain points of high procurement cost and long delivery cycle of imported hydraulic pumps.

4.2 Genuine Factory Direct Supply & Spot Inventory

As a source manufacturer with independent R&D and production workshops, we eliminate intermediate dealers’ markup and provide ultra-competitive ex-factory prices. Sufficient spot stock supports bulk batch orders and urgent order delivery, greatly shortening customer procurement cycle and improving project progress efficiency.

4.3 Industrial-Grade Heavy-Duty Durability

Core components such as cylinder block, plunger, valve plate and main shaft adopt high-strength wear-resistant alloy integral forging and ultra-precision mirror grinding process. The reinforced pump body structure effectively resists high pressure, mechanical impact and high-low temperature fatigue, adapting to long-term extreme harsh working conditions and extending equipment service life.

4.4 Full-Cycle Professional After-Sales Service

We provide one-stop full-link services including free professional model selection guidance, remote installation and commissioning guidance, technical problem response and long-term after-sales maintenance consulting. The professional hydraulic technical team provides fast and efficient support to ensure worry-free purchase and use for global customers.
