V3 Series Variable Vane Pumps

V3 Series Variable Vane Pumps Overview

The V3 Series Variable Vane Pumps are high-performance hydraulic pumps designed to deliver stable pressure, low noise operation, and excellent energy efficiency. Featuring a variable displacement design, the V3 series automatically adjusts output flow according to system demand, making it an ideal choice for modern hydraulic systems that require precision control and energy savings.

Application Advantages

• easy commissioning due to automatic bleed facility

• low noise level

• high bearing life because of hydrodynamically lubricated plain bearings

• bronze-faced starting and control plates, giving low friction characteristics during marginal lubrication conditions.

1. What is a V3 Series Variable Vane Pump?

The V3 Series is a variable displacement vane pump that automatically adjusts flow output based on system pressure, ensuring efficient and stable hydraulic performance.

2. How does the variable displacement mechanism work?

It uses a pressure-compensated control system that changes the eccentricity between the rotor and cam ring. When system pressure reaches a set value, the pump reduces flow to maintain constant pressure.

3. What are the main advantages of V3 Series pumps?

Key benefits include:

• Energy saving

• Low noise operation

• Stable pressure output

• Reduced heat generation

• Longer service life

4. What is the typical working pressure range?

The V3 Series typically operates in a medium pressure range, usually up to 140–160 bar, depending on the specific model and configuration.

5. In which applications are V3 Series pumps commonly used?

They are widely used in:

• Injection molding machines

• Machine tools

• Hydraulic power units

• Die casting machines

• Industrial automation systems

6. How does the V3 pump improve energy efficiency?

By adjusting flow output according to demand, the pump avoids unnecessary energy consumption compared to fixed displacement pumps, especially in systems with variable loads.

7. Is maintenance of the V3 Series pump easy?

Yes. The pump features a simple and modular design, making it easy to service, replace parts, and reduce downtime.

8. What should be considered when selecting a V3 Series pump?

Key selection factors include:

• Required flow rate

• Operating pressure

• Speed range

• Type of hydraulic system

• Installation space and mounting requirements

Certifications & Quality Assurance

Charge pumps are manufactured in compliance with international standards, ensuring high performance and reliability:

ISO 9001: Certified for quality management systems.

CE Certification: Ensures compliance with European safety, health, and environmental protection standards.

RoHS Compliance: Ensures the pump does not contain hazardous materials.

Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
