4 HIGH/LOW MULTIPLE HYDRAULIC GEAR PUMPS 1HL, 1PHL & 2HL SERIES High/Low hydraulics gear pumps are the ultimate pump for applications which require a fast approach and/or return of the actuator at low loads and slow motion of the actuator at high loads. In particular these models offer the advantage of requiring lower power of the motor. The 1HL, 1PHL and 2HL High/Low hydraulic gear pumps are specifically designed double stage pumps with special integrated valves as shown in the hydraulic circuit diagram. specially designed for applications such as: 8waste compactors 8log splitters 8clamp mechanisms 8crimping machines 8metal forming machines, etc ) First stage high pressure 2) Second stage low pressure ) Unloading valve Technical Features 1HL SERIES 1PHL SERIES 2HL SERIES First stage, low displacement, high pressure 1.4 cm³/rev to 4.1 cm³/rev P1 = 250 bar 1.1 cm³/rev to.2 cm³/rev P1 = 20 bar 4.5 cm³/rev to 8. cm³/rev P1 = 250 bar Second stage, high displacement, low pressure 4.1 cm³/rev to 1.8 cm³/rev (Pressure set by unloading valve).7 cm³/rev to 8.0 cm³/rev (Pressure set by unloading valve) 9.6 cm³/rev to 5.2 cm³/rev (Pressure set by unloading valve) Unloading valve Standard setting 0 bar Standard setting 0 bar Standard setting 50 bar RPM pump range 1000 rpm to 500 rpm 1000 rpm to 500 rpm 1000 rpm to 500 rpm Ports Common inlet.
