Complete Guide to Veljan Hydraulic Pumps: Types, Features & Applications
Hydraulic pumps are the heart of any hydraulic system, responsible for converting mechanical energy into hydraulic energy that powers machines across industries. Among the trusted names in India’s hydraulic industry, Veljan has built a strong reputation for delivering reliable, efficient, and high-performance hydraulic pumps.
In this comprehensive guide, we’ll explore Veljan hydraulic pumps in detail — including their types, working principles, features, specifications, and applications.
🔧 What Are Veljan Hydraulic Pumps?
Veljan hydraulic pumps are devices designed to convert mechanical power into hydraulic energy by moving fluid through a system. These pumps create flow, which generates pressure when resistance is encountered, enabling the operation of hydraulic motors, cylinders, and other components.
Veljan is known for manufacturing high-quality vane pumps and piston pumps widely used in industrial and mobile hydraulic systems.
⚙️ How Hydraulic Pumps Work
The working principle of a hydraulic pump is simple but powerful:
- Mechanical energy is supplied by an electric motor or engine
- The pump creates a vacuum at the inlet
- Hydraulic fluid is drawn into the pump
- The fluid is pushed out under pressure into the system
- This pressurized fluid powers actuators like motors and cylinders
The pump itself does not create pressure — it creates flow. Pressure builds when the fluid meets resistance.
