Hughes Pumps Ultrabar 30 ES-B | Skid Mounted UHP Water Jetting Unit

The Hughes Pumps Ultrabar 30 ES-B is a skid mounted, electric motor driven ultra high pressure water jetting unit designed for demanding industrial and marine cleaning duties. Built around the Ultrabar 30 pump, the unit is available with a performance range from 10 to 30 lpm at 2800 bar and is suitable for applications including surface preparation, descaling, heat exchanger cleaning, pipe cleaning, vessel cleaning, subsea cleaning, and more.

The standard build combines the Ultrabar 30 pump with pressure lubrication and oil cooling, modular fluid head assembly, solid carbide plungers, and integral gearbox into a robust skid package. A key feature of this model is that the modular fluid head assembly allows easy maintenance and troubleshooting on individual cylinders, which can help reduce service time in demanding UHP applications.

The system also includes an analogue pressure gauge for discharge pressure display, burst disc assembly, manual pressure adjusting valve, and pump switches for low inlet pressure and high oil temperature. For water supply and inlet protection, the Ultrabar 30 ES-B is fitted with a polypropylene water tank, boost pump, and dual filtration.

Electrical control is handled through a star delta starter control panel complete with interlocked isolator, start/stop buttons, hours counter, shutdown circuit for pump switches, and emergency stop. The panel also includes a PILZ safety relay and terminals for a remote E-stop, mounted in a coated sheet steel IP65 enclosure.

The standard motor specification is an IE3/IE4 foot mounted 4-pole electric motor, IP55, Class F insulation, Class B rise, TEFC, fitted with PTC thermistors, and suitable for 400V 3ph 50Hz and 480V 3ph 60Hz supplies. Fabricated components are grit blasted and powder coated with a zinc rich primer and durable topcoat, helping protect the unit in corrosive environments.

The datasheet also lists a broad range of build options, including pneumatic pressure adjusting/dump valve, air compressor, site trailer/trolley, crashframe, certified crashframe, mounted in a 10′ container standard or DNV, ATEX Zone 1 or 2 electric motors and starter panels, and a full range of accessories for different applications.

Why Choose the Hughes Pumps Ultrabar 30 ES-B?

The Ultrabar 30 ES-B gives operators a ready-built ultra high pressure water jetting package rather than just a standalone pump. That makes it useful for projects where users need a practical skid-mounted system with integrated water tank, inlet conditioning, electrical controls, and safety features already configured into one unit.

Its UHP performance class, modular fluid head design, and broad build-option range also make it well suited to contractors and operators who need a more service-friendly electric jetting unit for workshop, site, marine, offshore, or subsea cleaning duties.
