Hughes Pumps HP65 EC | Crashframe Mounted High Pressure Water Jetting Unit

The Hughes Pumps HP65 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 HP65 pump, the unit is suitable for applications including surface cleaning, descaling, heat exchanger cleaning, pipe cleaning, vessel cleaning, and more.

The standard build combines the HP65 pump with oil cooling, stainless steel pumphead, hard wearing plungers, and integral gearbox into a compact crashframe package. 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 HP65 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 build can also be tailored for different operating environments, with options such as pneumatic control valve, air compressor, ATEX Zone 1 or 2 electric motors and starter panels, and a full range of accessories for different applications.

Why Choose the Hughes Pumps HP65 EC?

The HP65 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 electric drive, oil-cooled HP65 pump, and protective crashframe format also makes it suitable for contractors and operators who need a durable jetting unit for workshop, site, marine, or offshore cleaning duties.

Does the HP65 EC include oil cooling?

This draft is based on the HP65 ES-B version, which uses an HP65 pump with oil cooling. This should be confirmed against the HP65 EC datasheet.

What motor options are available?

This draft uses the same motor options as the HP65 ES-B version: 37 kW (50 hp) and 45 kW (60 hp).

What is the maximum listed pressure?

This draft uses the same performance basis as the HP65 ES-B version, with listed pressures up to 1000 bar.

Does the unit include its own water tank and filtration?

This draft assumes the same arrangement as the HP65 ES-B version, including a polypropylene water tank, boost pump, and dual filtration.

Is an ATEX version available?

This draft assumes the same optional ATEX Zone 1 or 2 electric motors and starter panels as the HP65 ES-B version.
