| | | |
| | | The "Shoebox" Pump is a low cost, compact unit used on smaller hydraulic circuits. Its small size offers the versatility of mounting on wheels (such as a workcart) and moving the pump from workstation to workstation. Because StayLock Clamps do not need constant hydraulic pressure, the "Shoebox" is an ideal power source for StayLock Clamp applications. Like the High Volume Pump, this pump allows independent control of multiple workstations. | | |

| | | Pump Performance The maximum output pressure at no flow is somewhat above the nominal ratio times the air drive pressure. This relationship will fall off due to the increased effect of the air drive return spring force (equivalent to approximately 6 psi air drive at top of stroke, 8 psi at bottom of stroke). Data is based on standard muffler arrangement and on flooded suction. | | |
