Danfoss / Eaton-3.00 CID (49 CC) (420)OLD P/N 421A

Description & Features

Designed for demanding mobile hydraulic applications, the Danfoss / Eaton-3.00 CID (49 CC) (420)OLD P/N 421A is an open circuit piston pump from the X20 420 Series, offering a displacement of 3.00 CID (49 cc). Built to handle high pressure and flow requirements, it supports advanced control options that help match output to application demand across a wide range of mobile equipment.

Typical installations include loader backhoes, agriculture tractors, crawler dozers, mini excavators, articulate haulers, concrete and asphalt pavers, vibratory cable plows, and container handling equipment, among others. The pump is also suited to mining machinery, tunnel boring equipment, railroad equipment, utility boom trucks, rough terrain forklifts, and feller/bunchers. Fast response and recovery characteristics make it well suited to mobile equipment where hydraulic demand shifts frequently under load.

Question by: Rusty G on May 23, 2025, 9:32 PM
We run a loader backhoe pretty hard most days and been looking at piston pumps in this size range. This the 3.00 CID unit from the 420 Series?
Answer by: Customer Support on May 25, 2025, 6:24 PM
Yeah, that's the one. It's rated at 3.00 CID, which is 49 cc, and it comes out of Danfoss/Eaton's X20 420 Series line. Loader backhoes are actually one of the primary applications this pump was built around, so it fits right in with that kind of work. The open circuit piston design handles high pressure and flow demands well, which matters a lot when you're pushing that equipment through a full shift.
