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.
