VMI Horizontal Dredge Hydraulics |
The hydraulic system provides power to all of the dredging components. VMI horizontal dredges are equipped
with four independent hydraulic pumps to provide ample flow to all hydraulic components without starvation. All
continuously operated dredging functions are equipped with variable speed so you can optimize between engine
speed and hydraulic operation speeds.
A closed loop, heavy duty, variable speed piston pump and motor are used to run the centrifugal dredge pump.
The centrifugal dredge pump hydraulic system utilizes a high pressure filter, as well as a dedicated hydraulic
tank. An additional closed loop piston pump and motor are used to run the cutter head drive. This system also
includes a high pressure filter and has variable speed control. The traverse winch drive system uses a closed
loop piston pump and gearotor motor with variable speed. An open loop gear pump in conjunction with a two
way self centering valve with safety relief provides flow to the two heavy duty dual action hydraulic boom
cylinders.
Enhanced filtration includes: suction and return, as well as high-pressure filters to extend the life of all hydraulic
mechanisms. Hydraulic oil coolers are also incorporated to allow the system to run continuously even in
extreme conditions without excessive heating. For added protection automated alarms and manual monitoring
devices are provided for each dredge function.
