Material Our 2stage wood splitter hydraulic pump kit is made of highstrength cast iron, which is sturdy and durable, and can work stably under high pressure, reducing maintenance costs. Application scope This hydraulic pump is very suitable for presses, log separators, clamping devices, compactors, and other machinery. The maximum pressure during operation is 4000 PSI, which allows the actuators in the log separator to quickly approach and retract, making the operation of the hydraulic wood separator easy. Reasonable design and exquisite manufacturing techniques have enabled us to produce highquality products. Our hydraulic log separator pump has the characteristics of stable torque and speed output, low power consumption, strong load force, low heat generation, low noise, and long service life.
