VC

Product catalog summary

Document Overview:
This technical document provides information on the VC (Vented Pressure Compensator) designed for PVX Series Variable Displacement Piston Pumps. It includes performance data, contact information for the manufacturer, and a graphical representation of pump output flow relative to pressure.

1. Product Description

The VC is a vented pressure compensator intended for use with PVX Series pumps. These pumps are variable displacement piston pumps, which adjust flow based on system pressure to maintain efficient operation.

2. Performance Specifications

The document presents standard pressure-compensated performance data for the pump using ISO 32 hydraulic oil at 115°F. The key performance characteristic is the relationship between output flow (expressed as a percentage) and system pressure (psi).

3. Performance Graph Summary

The graph illustrates how the output flow decreases as pressure increases, demonstrating the pressure-compensated behavior of the pump. At low pressures, the pump delivers near 100% flow, which gradually reduces as pressure approaches the maximum rated value (around 4000 psi).

4. Manufacturer Contact Information

Manufacturer: Hartmann Controls
Address: 604 Progress Drive, Hartland, WI 53029, USA
