Product details

I. Product Overview

TheSVPF40is a high-performance hydraulic variable vane pump manufactured byYUKEN (Taiwan), part of the SVPF series. Renowned for its low noise, high efficiency, and compact design, this pump is widely used in hydraulic systems requiring precise flow and pressure control, such as injection molding machines, die-casting machines, construction machinery, and metallurgical equipment.

II. Technical Specifications

• Model: SVPF40 (common variants include SVPF-40-70-20, SVPF-40-55-20, etc., where numbers denote different pressure or configuration ratings).

• Displacement: 40 cm³/rev (some models may specify 40 L/min @ 1800 rpm).

• Rated Pressure: 70 bar (peak pressure up to 210 bar for certain models; confirm based on specific variant).

• Speed Range: 600–1,800 rpm (typical; refer to official manual for exact values).

• Fluid: Mineral-based hydraulic oil (ISO VG32 or VG46).

• Mounting: Flange-mounted.

• Rotation Direction: Clockwise (viewed from the shaft end).

• Port Sizes: Varies by model (e.g., inlet/outlet: 1/2" PT, drain: 3/8" PT).

III. Key Features

1. Variable Displacement Control

• Adjusts flow and pressure infinitely via mechanisms like eccentricity or swashplate angle modulation, meeting dynamic system demands.

2. High Efficiency

• Advanced vane design minimizes energy loss, enhancing overall efficiency.

3. Stable Operation

• Maintains consistent performance under high-pressure and high-speed conditions, providing reliable hydraulic power.

4. Low Noise

• Optimized flow path and structural design reduce operational noise, suitable for confined or noise-sensitive environments.

5. Long Service Life

• Wear-resistant materials for critical components (e.g., vanes, stator) extend operational lifespan.

------

IV. Applications

• Injection Molding Machines: Precisely controls mold opening/closing and injection processes.

• Die-Casting Machines: Regulates metal injection speed and pressure for consistent casting quality.

• Construction Machinery: Powers hydraulic systems in excavators, cranes, etc.

• Metallurgical Equipment: Used in rolling mills, forging presses, and other hydraulic drives.

V. Selection & Usage Guidelines

1. Confirm Requirements

• Select the appropriate model based on system flow and pressure demands to avoid overpressure or overspeed operation.

2. Installation Requirements

• Ensure proper alignment between the pump shaft and drive shaft to prevent radial forces.

• Use a rigid mounting base to minimize vibration.

3. Fluid Management

• Use clean, recommended hydraulic oil; maintain oil temperature between 15–60°C.

• Install a suction filter (≥25 μm filtration) and replace oil/filters regularly.

4. Startup & Maintenance

• Prime the pump before initial startup or after prolonged shutdown to avoid dry running.

• Monitor oil level, quality, noise, and temperature during operation; address abnormalities promptly.

5. Safety Protection

• Equip the system with a relief valve for pressure protection to prevent pump damage.
