The Pump Measuring Tool Hub is to assist measurement activities during piston pump setup by keeping internal components correctly aligned. It helps maintain proper positional relationships between the port plate, barrel, and slipper retaining plate while required measurements are taken. Its components are steady in the correct orientation, supporting reliable spacing control throughout inspection and adjustment tasks.Attributes:• Maintains correct alignment between the port plate, barrel, and slipper retaining plate during piston pump measurement tasks.• Helps control uniform internal spacing while calculating and verifying pump measurements.• Assists stable positioning of components during inspection and adjustment procedures.Applications: The Pump Measuring Tool Hub is applied in piston pump setup and inspection operations where accurate internal alignment is necessary. It supports proper spacing and positioning of pump components during measurement and evaluation processes.
