VQ Series-double Pumps

VQ Series-double Pumps Overview

The VQ Series Double Vane Pumps are fixed-displacement hydraulic pumps designed with a dual-pump (tandem) structure, combining two vane pump sections within a single housing to deliver two independent hydraulic flows or higher combined displacement from one drive source. Known for their high pressure (up to 21 MPa / 3000 psi), compact size, and long service life, these pumps feature a high-performance “balanced vane” design with floating side plates for automatic wear compensation, ensuring excellent volumetric efficiency and smooth operation at high speeds. They offer flexible configuration options—various displacement combinations, mounting types, and shaft designs—making them ideal for industrial and mobile hydraulic systems such as construction machinery, power units, and steering or transmission systems. The cartridge-type structure simplifies maintenance and replacement, while the ten-vane design minimizes noise and enhances performance under cold-start or high-viscosity conditions.

Key Features and Advantages

• Dual-Output Design: The VQ Series features a tandem (dual-pump) structure that allows for two independent hydraulic circuits or a higher combined flow, increasing versatility and efficiency in various applications.

• High Pressure Capability: These pumps are designed to handle high pressure (up to 21 MPa or 3000 psi), making them suitable for demanding industrial and mobile machinery applications where reliability and performance under pressure are critical.

• Efficient and Quiet Operation: The balanced vane design and floating side plates ensure smooth operation, reducing noise levels and improving volumetric efficiency, even under high-speed or high-pressure conditions.

• Durable and Long-Lasting: With a robust construction and advanced materials, VQ pumps are designed for durability and a long service life, even in harsh environments or heavy-duty usage.

• Flexible Configuration Options: Available in a wide range of displacement combinations, mounting types, and shaft configurations, making it easy to integrate into various hydraulic systems. Customizable options ensure compatibility with different machinery requirements.

• Easy Maintenance: The modular design allows for easy maintenance and repair. The cartridge-style construction simplifies replacement of parts, reducing downtime and maintenance costs.

• Cold Start and High Viscosity Performance: The VQ Series is engineered for reliable performance even in low-temperature or high-viscosity environments, ensuring smooth start-up and operation under challenging conditions.

• Compact Size: Despite its high performance, the VQ Series maintains a compact form factor, saving installation space and allowing for easier integration into tight spaces within machinery.

• Energy Efficiency: The high efficiency of the VQ pumps reduces energy consumption, contributing to cost savings over time and more sustainable hydraulic operation.

• Wide Application Range: Ideal for use in a variety of industries, including construction, mining, material handling, and agricultural machinery, as well as industrial hydraulic power units and steering systems.
