The Hughes Pumps HP120 EC is a crashframe mounted, electric motor driven high pressure water jetting unit designed for demanding industrial and marine cleaning duties. Built around the HP120 pump, the unit is suitable for applications including surface cleaning, descaling, heat exchanger cleaning, pipe cleaning, vessel cleaning, subsea cleaning, and more.
The standard build combines the HP120 pump, stainless steel pumphead, solid ceramic or carbide plungers, and integral gearbox into a robust crashframe package. The system also includes either a transducer or analogue pressure gauge for discharge pressure display, burst disc assembly or safety valve, manual pressure adjusting valve, and pump switches for low inlet pressure and high oil temperature.
For water supply and inlet protection, the HP120 EC is fitted with a stainless steel 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 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 control valve, air compressor, modular chassis options including skids, crashframes, site trailers or trolleys, with or without enclosures, certified crashframe, 10′ container build standard or DNV, ATEX Zone 1 or 2 electric motors and starter panels, and a full range of accessories for different applications.
The product image on page 1 is labelled HP120 EC and visually shows the crashframe mounted layout, while also noting that the image shown includes an Ultrabar 30 UHP pumphead.

Why Choose the Hughes Pumps HP120 EC?
The HP120 EC gives operators a ready-built high pressure water jetting package rather than just a standalone pump. That makes it useful for projects where users need a practical crashframe mounted system with integrated water tank, inlet conditioning, electrical controls, and safety features already configured into one unit.
Its higher pressure capability, robust frame format, and broader build-option range also make it well suited to contractors and operators who need a more capable electric jetting unit for workshop, site, marine, offshore, or subsea cleaning duties.
