This is a NEW (never used) but older 12 VDC double acting Monarch M-3551 power unit. Pump flow is .138 cu in/rev, reservoir has a useable capacity of about 5/8 gallon. Main relief pressure can be set up to 3000psi. Pressure ports are 1/4" NPT. Included is a 10ft. x 18/4 control cord.
I tested this pump myself and everything works properly, guaranteed not to be DOA. There is no other warranty.
