Product Description
Transit Mixer Eaton 3933 4633 5433 6433 7630 motor
Hydraulic Eaton concrete mixer truck motor 3933 4633 5433 6433 7630
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.
Advanced cylinder barrel design - permits high speed and pressure.
Fixed clearance slipper hold down - on Models 39 through 64 allows operation at high speed and reduces friction. Model 76 is a ball guide unit.
Pistons - have long engagement with cylinder bore resulting in low leakage.
Hydraulic servo control - provides low effort operation with low control pressure. Large servo pistons hold swash plate position and provide damping.
Large case drain ports - minimize case back pressure.
