The Pump Measuring Tool Hub assists in achieving measurements during piston pump setup by keeping internal components correctly aligned. It holds the port plate, barrel, and slipper retaining plate in the proper relationship while measurements are taken. By maintaining uniform internal spacing, the tool supports reliable inspection and adjustment activities. It improves measurement accuracy and minimizes alignment variation during pump evaluation.Attributes:• Correct alignment among the port plate, barrel, and slipper retaining plate during piston pump measurement.• Helps preserve uniform internal spacing while measuring pump components.• Supports stable positioning during inspection and adjustment procedures.Applications: The Pump Measuring Tool Hub is used during piston pump assembly and inspection tasks that require accurate internal alignment. It helps ensure proper spacing and positioning of pump components during measurement activities.
