Key Features

Next generation seal technology, Flow HyPlex Prime

Next Generation Seal Technology

Utilizes the next generation of seal technology from Flow’s 94,000 psi HyperPressure™ pumps.

Pressure Loading Tool for HyPlex Prime

Pressure Loading Tool

Quickly, easily, and accurately perform maintenance on high-pressure components using a single wrench to tension four (4) tie rods simultaneously.

Flow's patented PAC-V technology

Patented PAC-V™ Technology

The PAC-V pressure control automatically adjusts water overflow when the jet turns off or when the operator changes orifice size reducing complexity of running an ultrahigh-pressure direct drive pump.

Modular Pump Design | HyPlex Prime with built in fork pockets

Modular Pump Design

Allows for a wide variety of options such as dual-pressure control. The HyPlex Prime is mounted on its own purpose-built skid for mobility, vibration isolation, and ease of service.

HyPlex Prime pumps combine HyperJet® technology with direct drive efficiency. The HyPlex Prime is the most reliable ultrahigh-pressure direct drive pump in the world. As the inventors of direct drive technology, Flow provides preventative maintenance interval kits to allow fast and consistent maintenance. Pressure loading tools quickly open the pump to access the replacement components. The same loading tool ensures perfect realignment upon reassembly. This technique is similar to that found on our most advanced 94,000 psi HyperJet pumps. In addition, Flow offers service contracts to eliminate nearly all pump maintenance.
