Piston Pump Flange

The flanges for piston pumps primarily use the SAE J518 standard (also known as ISO 6162), which is divided into Code 61 (3000 PSI series) and Code 62 (6000 PSI series) based on pressure rating. Key parameters include pressure rating, nominal size, material, and temperature range.

Key Features of Yuken flange

• High Pressure Resistance: Designed specifically for high-pressure hydraulic systems, conforming to SAE Code 62 standards (rated at 6000 PSI / 420 bar), and manufactured from high-strength steel.

• Standardized: Conforms to the SAE J518 (ISO 6162) industry standard, utilizing a common four-bolt mounting pattern to ensure global interchangeability.

• Reliable Sealing: Features an O-ring face seal design, effectively preventing leaks caused by high pressure and vibration, providing a zero-gap seal.

• Easy Installation: The split flange design facilitates quick installation and removal in confined spaces, making maintenance convenient.

• Multiple Connection Options: Available with various connection end types, including socket weld, butt weld, and threaded connections, to suit different piping requirements.

Application

• Heavy engineering and mining machinery: excavators, loaders, cranes, and drilling rigs, designed to withstand harsh outdoor environments and heavy-duty operations.

• Industrial manufacturing: injection molding machines, large hydraulic presses, and steel mill equipment, used for precise control and high-intensity production.

• Oil and gas: refineries, offshore platforms, and drilling equipment, used in critical fluid transfer and control systems.

• Energy and marine: power plants and ship steering systems, used to ensure safe and reliable high-pressure operation.

Packaging & Delivery

Hydraulic pumps are typically packaged securely to prevent damage during transit. The packaging includes:

Protective Wrapping: To safeguard the pump from environmental damage.

Custom Crates: For larger, heavier pumps, ensuring safe handling.

Documentation: Includes installation, maintenance instructions, and warranty details.

Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.

Certifications & Quality Assurance

All hydraulic pmps are manufactured in compliance with international standards, ensuring high performance and reliability:

ISO 9001: Certified for quality management systems.

CE Certification: Ensures compliance with European safety, health, and environmental protection standards.

RoHS Compliance: Ensures the pump does not contain hazardous materials.

Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
