Overview

This document presents technical information on the Electronic Flow (EF) Throttling Control system designed for PVX Series Pumps by Hartmann Controls. It focuses on the pressure loading response characteristics of pumps governed by this electronic control system.

Technical Specifications

• Fluid Type: ISO 32 oil
• Operating Temperature: 115°F
• Pressure Compensator Override Setting: 2500 psi

Performance Characteristics

The document includes a graph illustrating the relationship between output flow (in gallons per minute, gpm) and pressure (in psi) for various flow rates ranging from 20 gpm to 70 gpm. The graph demonstrates how the pump's output flow decreases as pressure increases, reflecting the throttling control behavior.

• Flow rates analyzed: 20, 30, 40, 50, and 70 gpm
• Pressure range: 0 to 3000 psi

Control System Functionality

The EF Throttling Control modulates pump output flow electronically to maintain desired flow rates under varying pressure loads. The pressure compensator override set at 2500 psi ensures the system limits pressure to protect the pump and maintain operational stability.
