Product Description
The V Series Single Pumps are high-performance, fixed-displacement vane pumps designed for medium-pressure industrial hydraulic applications. Featuring a compact intra-vane cartridge design with a 12-vane rotor, these pumps deliver smooth, low-noise operation and excellent volumetric efficiency. They offer a wide range of displacement options to suit various flow requirements and incorporate pressure-balanced construction to enhance reliability and extend service life. Widely used in injection molding machines, metalworking presses, and hydraulic power units, V Series Single Pumps are valued for their durability, ease of maintenance, and versatility in demanding industrial environments.
The pump’s vane assembly is housed in a compact, self-contained cartridge, allowing for easy maintenance and quick replacement without removing the entire pump.
Enhances volumetric efficiency and reduces internal leakage.
12-Vane Rotor System
Provides smooth and continuous flow with minimal pulsation, reducing noise and vibration in hydraulic systems.
Ideal for noise-sensitive applications.
Pressure-Balanced Construction
Internal pressure balancing reduces radial loads on the shaft and bearings, which increases the pump’s operational life and reliability.
Wide Displacement Range
Available in multiple displacement options (approximately 7 cc/rev to 193 cc/rev) to meet diverse flow and pressure requirements.
Compact and Robust Design
High power-to-weight ratio and small footprint simplify integration into hydraulic systems with limited space.
Low Noise Operation
Optimized vane design and internal flow paths significantly reduce noise levels compared to other pump types.
Versatile Mounting and Shaft Options
Multiple mounting flange types, shaft configurations, and outlet port positions provide flexibility for various industrial setups.
Easy Serviceability
Modular cartridge design facilitates quick servicing and replacement, minimizing downtime and maintenance costs.
Wide Application Suitability
Suitable for injection molding machines, metal presses, hydraulic power units, and other industrial hydraulic systems requiring medium pressure and reliable performance.
