1. Product Overview

2. Core Features

• Tri-Piece Cast Iron Construction: Offers exceptional structural strength and distribution flexibility, ensuring long service life even in harsh environments. The cast iron housing provides excellent resistance to wear, impact, and corrosion.
• Balanced Thrust Plates: Minimize internal friction and fluid leakage, enhancing volumetric efficiency (up to 98%) and reducing energy loss during operation.
• Integrated Journal Bearing Lubrication: Internal fluid channels continuously lubricate bushings, extending bearing life and improving overall reliability under high-pressure conditions.
• Flexible Configurations: Available in single, multiple (up to 6 sections), piggyback, and through-shaft drive configurations. Supports various mounting, shaft, and port options to meet diverse system requirements.
• Wide Fluid Compatibility: Suitable for mineral oil and fire-resistant fluids, including water-oil emulsions (HFB), water-glycol (HFC), and phosphate esters (HFD), expanding application scope in fire-sensitive environments.
• Integrated Valve Capabilities: Optional integrated valves such as load-sensing flow controls, anti-cavitation checks, solenoid unloading relief valves, and priority flow controls, reducing system complexity and potential leak points.
