Overview of Transfer Barrier* Technology

The Oilgear Company, a global leader in hydraulic drives and electronic control systems, offers the Transfer Barrier* pump, designed for high-performance applications requiring reliability and efficiency. This technology is suitable for industries needing advanced engineering solutions.

What is a Transfer Barrier* Pump?

The Transfer Barrier* pump utilizes fluid-powered pistons driven by oil cylinders, allowing for variable control of volume and pressure, resulting in improved efficiency over traditional crankshaft mechanical fixed pumps.

Advantages of Transfer Barrier* Pumps

• Variable flow system for speed and pressure control.
• Compatible with a wide range of aggressive fluids.
• Modular design for flexible configuration.
• Approximately 15% reduction in power consumption.
• Eliminates the need for accumulators by direct pumping to cylinders.
• Capable of high pressures up to 650 bar/9,430 psi.
• No output ripple, reducing the need for pulsation dampeners.
• Lower maintenance costs due to slower ram speeds.

Comparison with Triplex Pumps

The Transfer Barrier* pump operates at a slower ram speed (0.25 m/sec) compared to triplex pumps (2.5 m/sec), with a longer cycle time (8 sec vs. 0.2 sec) and reduced seal wear.
