High-Pressure Pumping with Precision Control

Our patented Transfer Barrier™ Pumping System allows for precise control when pumping high-pressure water, chemicals or slurries. Our unique design has been applied to a diverse range of applications—including fracking, LNG, water-jet cutting and press control.

BASICS

The Oilgear Transfer Barrier™ Pumping System uses the flow of oil from a hydraulic power unit (HPU) to control the motion of large pumping plungers with incredible accuracy. These plungers can pump chemicals, slurries or high-pressure water. Based on the area ratios (piston vs. rod) of the plungers, the Transfer Barrier can intensify or reduce output pressure.

THE TRANSFER BARRIER™ ADVANTAGE

The are four main reasons to select an Oilgear Transfer Barrier™ Pump for your tough, high-pressure application:

High Pressure Water Pumping System - Oilgear

Extremely Long Life

Our plungers are hydraulically driven—not mechanically. This allows for huge on-axis force. Large force means large plungers. It means fewer cycles. And, ultimately, longer seal and valve life.

Precision Pumping Control

The Transfer Barrier™ pump is variable displacement with almost zero output ripple. Oilgear uses proprietary control algorithms to achieve precision pumping control.

Flexible Packaging

Because the Transfer Barrier™ pump is driven hydraulically, the packaging can be easily adjusted to fit your footprint. For example, the HPU and electrics can be remotely located.

Uptime

The Transfer Barrier™ pump can be configured to continue functioning, even if repairs are needed on part of the system. A triplex Transfer Barrier™ pump can easily change over to a duplex pump on the fly—simply by isolating the problematic components and changing the control algorithm.
