Key Technical Features

1. Thrustproof Integrated Dual Helical Gear Reducer

• Features integrated double helical reduction gears providing a compact design, accurate transmission, and no internal wear parts.
• Utilizes a floating crankshaft and pinion shaft to free the assembly from axial loads and eliminate thrust, extending bearing life.
• Reduces stress concentration at the crankshaft and gear to maximize overall system reliability.
• Equipped with double-row spherical roller crank bearings for self-alignment under heavy loads.
• Includes a non-sparking labyrinth seal on the gear shaft for permanent durability.

2. Wearproof Forced Lubrication System

• Driven directly by the crankshaft, an internal forced lubrication oil pump supplies pressurized lubricating oil to all moving components.
• A unique step-type crosshead acts as a piston, pumping oil directly through the rod hole to the crank bearing during the rearward stroke.
• Operates with a low lubrication oil level, which minimizes oil consumption and reduces heat generated by oil mixing.

3. Leakproof Seal & Sealing Structure

• Standard design uses a spring-loaded, self-adjusting, and self-tightening V-ring seal that minimizes friction and lowers maintenance needs.
• Features a stuffing box packing that is spring-actuated, removing the need for manual external gland adjustments.
• Offers a double-seal configuration with an internal leakage return design to prevent hazardous emissions into the atmosphere.
• Allows for flushing or lubrication between primary and auxiliary seals, safely collecting hazardous liquids via a flush pipe.

4. Crackproof Liquid End Design

• Optimized with Finite Element Analysis (FEA) fatigue analysis and advanced spark machining for rounded intersections to eliminate stress concentrations.
• High-Pressure Configuration:Incorporates a single-piece coaxial valve that combines both suction and discharge functions. This divides the pump head into distinct high- and low-pressure zones, eliminating alternating stress and preventing fatigue failure.
