• Closed & open loop combination hydraulic systems provide quiet, efficient, clean and reliable operation.
• Two hydrostatic pumps are dedicated to the pump unit's drive cylinder while a single variable displacement, pressure compensated, axial piston pump drives the shift cylinder. The hydraulic charge pump is then free to continuously circulate the hydraulic fluid through the full path hydraulic filters and cooler.
• Supplementary timing proximity switches are installed throughout the pumping unit to provide backup and redundancy guarantying flawlessly continuous operation prior to normally scheduled maintenance stops.
• Heavy duty hard chrome-plated concrete conveying cylinders enhance longevity and reduce maintenance.
• Feed hopper with heavy-duty agitator assures proper concrete delivery to cylinders suctions end, even when pumping harsh, stiff mixes.
