Introduction
Understanding the model code on an Eaton hydraulic pump is essential for identifying the pump’s specifications and ensuring proper maintenance and replacement. This guide will help you decipher the code on an Eaton hydraulic pump.
Locate the Model Code
Find the Label: The model code is typically printed on a label affixed to the pump. Look for a sticker or metal plate on the pump housing.
Identify the Code: The model code consists of a series of letters and numbers that provide information about the pump’s characteristics.
Understanding the Code Structure
Pump Type: The first part of the code indicates the pump type. For example, “PVM” stands for a variable displacement piston pump.
Displacement: The next part of the code specifies the displacement of the pump in cubic inches per revolution. For example, “057” indicates a displacement of 0.57 cubic inches per revolution.
Mounting Style: The code includes a letter or number that indicates the mounting style of the pump. For example, “F” might indicate a flange mounting.
Shaft Type: The code also specifies the shaft type. For example, “S” might indicate a splined shaft.
Port Connections: The code includes information about the inlet and outlet port connections. For example, “B” might indicate BSPP threads.
Additional Features: The code may include additional letters or numbers that specify other features, such as pressure settings or special modifications.
Using the Eaton Identification Guide
Refer to the Guide: Use the Eaton hydraulic pump identification guide to decode the specific model code. The guide provides detailed information about each part of the code.
Online Resources: Visit the Eaton website or refer to the pump manual for additional information and resources.
Example
Let’s decipher the code “PVM057F1S1B1” as an example:
PVM: Variable displacement piston pump
057: 0.57 cubic inches per revolution
F: Flange mounting
1: Standard configuration
S: Splined shaft
1: Standard configuration
B: BSPP threads
1: Standard configuration
