Hughes Pumps HP40 EC | Crashframe Mounted High Pressure Water Jetting Unit

The Hughes Pumps HP40 EC is a Crashframe mounted, electric motor driven high pressure water jetting unit designed for a wide range of industrial cleaning and maintenance duties. Built around the proven HP40 pump, the unit is suitable for applications including surface cleaning, descaling, heat exchanger cleaning, pipe cleaning, vessel cleaning, and more. The main application summary and performance options are shown on the datasheet page.

The standard build combines the HP40 pump, stainless steel pumphead, hard wearing plungers, and integral gearbox into a compact Crashframe. The system also includes an analogue pressure gauge for discharge pressure indication, 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 HP40 EC 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 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 range of build options, including pneumatic control valve, air compressor, site trailer, crashframe, certified crashframe, ATEX Zone 1 or 2 electric motors and starter panels, and a full range of accessories for different applications.

Why Choose the Hughes Pumps HP40 EC?

The HP40 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 combination of compact footprint, electric drive, and optional accessories also makes it suitable for contractors and operators who may need to tailor the package for workshop, site, marine, or offshore cleaning tasks.
