PVB Compact Variable Displacement Pump For Metallurgical Machinery

PVB High-Performance, Compact Variable Pump For Metallurgical Machinery

1, Product Overview

The PVB pump is a swashplate-type axial piston variable displacement pump designed primarily for open circuits. Renowned for its compact design, high power density, and exceptional efficiency, this series is a cornerstone in heavy industry, industrial hydraulics, and mobile machinery.

2, Key Features

· High-Pressure Performance: Capable of operating at maximum pressures up to 350 bar and higher (depending on the model and controls), delivering robust power output.
· High Volumetric Efficiency: Precision manufacturing ensures minimal internal leakage, resulting in high volumetric and overall efficiency across the entire pressure range, contributing to energy savings.
· Multiple Control Options: The PVB pump is available with various control types to meet diverse system requirements. Common options include:
· Constant Power Control (e.g., LR/LS): Automatically adjusts displacement to prevent the pump's output power from exceeding a set value, protecting the prime mover (electric motor or engine) from overload.
· Pressure Cut-Off Control (e.g., DA): Rapidly reduces displacement to a level just sufficient for leakage compensation when system pressure reaches a preset value, saving energy and providing soft starts.
· Electro-Proportional Control (e.g., E1): Allows for infinite adjustment of displacement or pressure settings via an external electrical signal (current/voltage), facilitating automated control.
· Load Sensing Control (e.g., LSH): Maintains the pump's output pressure at a constant margin above the highest load pressure in the system. This enables precise, load-independent control of actuator speed and significantly reduces energy consumption.
· Long Service Life & High Reliability: The use of high-quality bearings and friction pair materials, combined with optimized hydrodynamic design, ensures long service life and reliable operation even under harsh conditions.
· Low Noise Level: Optimized port plate design and noise reduction technologies contribute to smooth and quiet operation.

3,Typical Applications

· Injection Molding Machines
· Hydraulic Presses
