Press Brake-Hydraulic Pump
Product Description
Hydraulic Pump in Press Brake Systems
Powering Precision with Reliable Hydraulic Energy
The hydraulic pump is the heart of a press brake's hydraulic system. Its core function is to convert mechanical energy (from an electric motor) into hydraulic energy by generating a pressurized flow of hydraulic fluid. This flow drives the hydraulic cylinders, enabling precise movement of the ram and consistent force application during the bending process.
✅ Core Function
The hydraulic pump creates flow and pressure in the hydraulic circuit, supplying energy to all actuators in the system. Without sufficient and stable flow from the pump, the hydraulic press brake cannot operate reliably or accurately.
In modern press brakes, variable-speed pumps are often used to improve energy efficiency and adjust pressure on demand. The choice of pump type directly impacts the machine’s performance, efficiency, and noise levels.
Common Types of Hydraulic Pumps
Gear Pumps (External/Internal)
Simple structure, cost-effective
Good for low to medium pressure (up to 210 bar)
Used in entry-level or general-purpose press brakes
Vane Pumps
Quiet operation, smooth flow
Suitable for moderate pressures (up to 210–250 bar)
Offers balanced performance and efficiency
Piston Pumps (Axial or Radial)
High efficiency and pressure (up to 350+ bar)
Ideal for high-tonnage and CNC press brakes
Provides precise flow control and long service life
Our product range covers all three types, ensuring compatibility with both conventional and high-end CNC press brakes.
⚙️ Key Components & Material Highlights
Pump Housing: High-strength cast iron or aluminum alloy, ensuring heat dissipation and structural integrity.
Gears / Pistons / Vanes: Made from hardened alloy steel, providing wear resistance under high-pressure operation.
Bearings and Shafts: Designed for continuous-duty cycles and optimal alignment.
