Flow MotoJet


Full Diagnostic Intelligence

Digital pressure transducer and display make it easy for operators to see their operating pressure, reducing the possibility of damaged work materials due to incorrect pressure.

Fully Electronic Pressure Control

Pressure setting and control is integrated into the machine operator station, greatly enhancing operator convenience.

Built-in Safety

Automatic high-pressure bleed-down valve relieves system water pressure to 0 psi [0 bar] within one second of shutting down the pump.

Dual Pressure Control

Designed for applications where a low-pressure pierce may be necessary before a higher pressure cutting operation, the dual pressure control provides a simple way to switch between two output pressures.

Cooling Water Flow

Thermostatically controlled valve regulates cooling water flow while minimizing water usage. This enhances pump performance and optimizes inlet water usage.

Maintenance-Free Attenuator

With the largest pressure-shock attenuator available (124 cubic inch or 2.02 liter), Flow pumps deliver consistent water pressure every day. No maintenance is required.

User-Friendly Pump Enclosure

The pump enclosure is visually and functionally integrated into the machine tool system and features convenient, user-friendly designs: air assisted lifting top, removable side panels for full maintenance accessibility, handle-integrated status light, interior work light, and sound deadening materials.

Equipped with Waterjet Connect™

Every MotoJet pump comes equipped with Waterjet Connect — your unique, one-stop-shop for accessing all things related to your waterjet system. Order parts, schedule service, view your order history, and more through your Waterjet Connect account.
