Eaton 5423 Series Hydraulic Variable Pump

Product Description

Eaton 5423 Hydraulic Axial Piston Pump For ExcavatorProduct DescriptionHydraulic 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.
Product FeatureDrive 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.

For the drum drive in mobile concrete mixers A4VTG071, A4VGT090 series.
-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.
