USED 1992 HAUHINCO EHP3K15050

Hauhinco EHP-3K 150/50 Triplex Pump | 75 HP Reliance MotorThe Hauhinco EHP-3K series is the global gold standard for high-pressure water hydraulics and longwall mining support. This EHP-3K 150/50 model is a horizontal 3-cylinder reciprocating plunger pump designed for 24/7 continuous duty in the most punishing environments. Coupled with a 75 HP Reliance industrial motor, this package is engineered to deliver extreme pressures (up to 5,800 PSI) for descaling, hydraulic roof support, and high-pressure process injection.Manufactured in 1992, this unit represents the height of Hauhinco's robust mechanical engineering. The heavy-duty crankcase features an integrated forced-oil lubrication system, ensuring that all internal components remain cooled and lubricated even under maximum load. The "service-friendly" design allows for the liquid end and plungers to be maintained without the need for specialized heavy machinery, significantly reducing plant downtime.Technical SpecificationsManufacturer: HauhincoModel: EHP-3K 150/50Year of Manufacture: 1992Pump Type: High-Pressure Triplex PlungerDrive Motor: 75 HP Reliance ElectricVoltage: 460V (3-Phase)Max Pressure: Up to 5,800 PSI (400 Bar)Flow Rate: ~40–60 GPM (Depending on plunger size/RPM)Lubrication: Integrated forced-oil systemApplication: Mining, Descaling, Water HydraulicsKey FeaturesReliance Industrial Drive: The 75 HP Reliance motor provides the massive torque and mechanical reliability required to drive a reciprocating high-pressure plunger system under full load.Mining-Grade Durability: Built with heavy-walled castings and specialized plunger seals designed to handle high-mineral content water and industrial emulsions.Low Pulsation Flow: The triplex (three-cylinder) design provides a significantly smoother flow and reduced vibration compared to standard duplex pumps, protecting downstream piping and valves.Integrated Cooling & Lube: The self-contained lubrication system ensures the crankcase survives long-duration runs in high-ambient temperature environments.
