HYDSUNRIDA LD-P7D3R1A9A2B00 High Pressure Variable Piston Pump | 57799322 Russia Mining Replacement Pump

HYDSUNRIDA LD-P7D3R1A9A2B00 High Pressure Variable Piston Pump | 57799322 Russia Mining Replacement Pump

1. Product Overview

HYDSUNRIDA LD-P7D3 series high-pressure variable piston pump (Part No. 57799322) is professionally optimized for Russia’s alpine mining, open-pit heavy-duty and 24-hour continuous operation scenarios. Featuring 119cc/r large displacement and 345bar ultra-high pressure, it fully matches original equipment parameters and realizes 1:1 non-destructive replacement for Atlas Copco and Epiroc drilling rigs, drill jumbos and air compressor hydraulic systems. Validated by seven years of mass production and actual mining operation, this pump delivers stable low-temperature startup, precise high-pressure holding, low internal leakage and long wear resistance. It effectively solves common defects of ordinary replacement pumps such as insufficient pressure, pressure drop, low-temperature failure and fast abrasion, serving as a cost-effective and reliable solution for Russian mining equipment replacement.All LD-P7D3 piston pumps are ISO9001:2015 and SGS certified. Every unit undergoes strict high-pressure testing before delivery, ensuring stable performance and high durability under extreme working conditions.

2. Full Product Model Coverage

The LD-P7 series covers customized versions for diverse Russian mining conditions, adapting to temperate, cold and extreme cold field environments with precise and error-free replacement:

• 4A Standard Electronic Control: Suitable for stable operation in temperate mining areas

• 8A Heavy-duty Electronic Control: Designed for high-frequency impact and high-load drilling conditions

• 9A Extreme Cold Electronic Control: Popular version for Russia, supporting -40℃ ultra-low temperature startup and harsh open-air weather conditions

• Non-standard Customization: Adjustable pressure range, variable displacement range and sealing structure according to equipment requirements

3. Core Technical Parameters

All parameters strictly comply with original P7D standards. After replacement, the equipment’s flow, pressure, speed and power output remain consistent with the original state without performance attenuation or compatibility issues.

4. Product Core Advantages

HYDSUNRIDA LD-P7D3 mining piston pumps deliver original-level performance and extreme condition adaptability, with comprehensive advantages over ordinary replacement products:

• Original-level Zero-error Replacement: 119cc large displacement and 345bar ultra-high pressure fully match the original hydraulic system. The mounting size, flange, oil port, electronic control and pressure curve are 1:1 universal, requiring no equipment modification or debugging for direct installation.

• 7-year Mature Mass Production & Field Verification: Core components adopt precision independent finishing and automatic assembly. Each pump passes strict high-pressure testing, adapting to 24-hour continuous heavy load, high-frequency impact, dust and low-temperature mining working conditions.

• Special Optimization for Russian Extreme Cold Conditions: Optimized sealing, lubrication and electronic control low-temperature performance for Siberian, Far East and Ural alpine regions. It ensures smooth startup at -40℃ without pressure drop or stalling, supporting all-weather open-air operation.

• Manufacturer sells directly, highly competitive market pricing: Adequate factory spot inventory effectively solves the problems of long procurement cycles, high prices and unstable supply of imported pumps, supporting long-term stable bulk orders for Russia.

• Customization & Complete Hydraulic Supporting: Customizable pressure range, variable response and cold-resistant configuration. Supporting hydraulic motors, valve groups and power units of the same series are available to realize one-stop supporting for mining hydraulic systems.

5. Compatible Equipment Models

LD-P7D3 piston pumps are widely compatible with mainstream Epiroc and Atlas Copco mining equipment in Russian mining areas, featuring strong replacement compatibility and stable operation after installation:

• Drill Jumbos: BOOMER 281, 282, 291, 292, E10, E20, S1 and other full-series underground tunneling equipment

• Open-pit Drilling Rigs: FlexiROC, PowerROC, D-series and T-series top hammer and down-the-hole drilling rigs

• Mining Air Compressors: XATS, XAHS, XAVS, XRHS series mobile air compressor hydraulic systems

• Exploration Equipment: Hydraulic power units for field core drilling, sampling drilling and pile foundation drilling equipment

6. Overseas After-sales Guarantee

All LD-P7D3 series piston pumps come with 12-month overall warranty, and core components support extended warranty. We provide English and Russian bilingual technical support, with 7×24-hour remote guidance for installation, commissioning and troubleshooting. Complete export qualification and customs clearance documents are available to support bulk foreign trade orders and large-scale mining project cooperation in Russia.
