VICKER 70453-LBG 78453-LAV Hydraulic Pump

1. Model structure and meaning analysis
This model can be divided into two parts:
70453: Core directory number. This string of numbers is a code used internally by Eaton VICKERS to uniquely identify a specific product configuration. It locks all of the following information:
Pump core series and displacement: The core of this pump is VICKERS' PVH series inclined disc axial piston pump. 70453 corresponds to a specific displacement specification (for example, it is likely to be 74 cc/rev or 98 cc/rev, which needs to be verified).
Control method: This is one of the most critical features. Based on experience, the control method represented by 70453 is highly likely to be "pressure compensation control". The outlet pressure of this pump will remain stable at the preset value. When the system pressure reaches the set point, the pump's displacement will automatically decrease to near zero, only replenishing leakage, thereby achieving energy conservation and system safety.
Installation of flanges and shaft extensions: defines the physical interface between the pump and the engine or motor (such as SAE flanges, metric flanges, and key spline shafts).
Oil port size and position: defines the standards for inlet, outlet, and housing drain ports.
LBG: suffix code. This set of letters defines variable options, typically including:
L: Usually represents the direction of rotation. It is likely to refer to "counterclockwise (CCW) rotation when viewed from the shaft end" here.
B: It may represent the type of shaft extension, such as a "B-type" spline or a specific key shaft.
G: May represent special options, such as specific sealing materials, paint codes, or modified versions for a major customer (OEM).
