Eaton 5423 Hydraulic Axial Piston Pump For Excavator
Hydraulic Eaton concrete mixer truck pump 4623 5423 6423 7620Closed circuit.Nominal Pressure: 420 bar (6000 psi) and Peak Pressure 480 bar (7000 psi). Displacement from 63.7 to 124,8 cm3/r (3,89 to 7,62 in3/r).
Eaton has the lead position in providing reliable and durable system solutions for transit mixers-vehicles on which downtime can mean disaster. Whether the truck is traveling down a highway or idling at a traffic light, the drum must maintain a consistent rotation speed. That's no problem when Eaton is on the inside. Eaton pump and motor provide the high pressure and high flow required to keep drums rotating.
Drive shafts - a wide variety of options are available to suit every need.
High strength swash plates on variable pumps and motors - resist deflection under high load.
High strength cast iron housings - provide greater noise damping and wall strength.
High flow check valves in pumps - keep the system primed with minimal pressure drop.
Charge pumps on pumps - gerotor type, several displacement options are available to suit the needs of every application. All cast iron construction.
Cartridge shaft seal - lends itself to easy serviceability. Mechanical face seal design tolerates high speed and high case pressures.

Transit Mixer Eaton 3933 4633 5433 6433 7630 motor
-Variable axial piston pump of swash plate design for hydrostatic drives in closed circuit
-The flow is proportional to the drive speed and displacement.
-The flow increases as the angle of the swash plate is adjusted from zero to its maximum value.
-Flow direction changes smoothly when the swash plate is moved through the neutral position.
-Two pressure-relief valves are provided on the high pressure ports to protect the hydrostatic transmission (pump and motor) from overload.
-The high-pressure relief valves also function as boost valves.
-The integrated boost pump acts as a feed pump and control pressure supply.
