The PHS0-18 Hydraulic Supply unit is designed to deliver hydraulic oil at 18 gpm @ 1000 psi (68.1 lpm @ 6.9 MPa). Typical uses are wash hydraulics for the entire car wash tunnel; supplying hydraulic fluid to side washers, tire washers, wraparounds and conveyors. If supplying more than one piece of equipment with the hydraulic unit, you must purchase hydraulic proportionator banks for each piece of equipment. This unit uses a Vickers Vane Pump and is direct driven by a 15 H.P. electrical motor.
