Hughes Pumps HP220 Pump | High Pressure Seawater Pump up to 1400 Bar

The Hughes Pumps HP220 Pump is a high pressure plunger pump designed for demanding seawater and industrial pressure applications. Rated up to 1400 bar at 62 lpm and capable of flows up to 277 lpm at 310 bar, the HP220 offers a strong combination of high pressure and high flow performance for offshore, marine, and industrial duty.

Built with a 316 stainless steel pump head for seawater applications, the HP220 is suited to corrosive marine environments where durability and material selection are critical. An optional 431 stainless steel pump head is also available for non-seawater applications.

The pump is available with a choice of gear ratio to suit either diesel engine or electric motor drive arrangements. For compact installations, an SAE adaptor housing in SAE 1, 2 or 3 can be supplied for flange mounting the pump to a diesel engine flywheel housing, helping create a compact, aligned installation while enclosing moving parts. The HP220 can also be supplied as a bareshaft pump only or as part of a complete unit build.

Internally, the HP220 uses an in-line valve arrangement for maximum efficiency and to prevent the adverse effects of cyclic stress in the pump head. It also features interchangeable plunger kits, a hardened alloy steel crankshaft with heavy duty roller main bearings, an SG iron crankcase with splash lubrication, and forged connecting rods with low friction shell type big end bearings and lead bronze lined small end bushes. The pump is gear driven, removing the need for belt drive.

The datasheet also lists options such as a pressure gauge, safety valve or burst disc, and solid tungsten carbide/ceramic plungers with self-adjusting seals. Hughes additionally notes that the HP220 is convertible to 2000/2800 bar, with reference to the Ultrabar 30 data sheet for those higher pressure configurations.

Why Choose the Hughes Pumps HP220 Pump?

The HP220 offers a broad performance envelope, allowing operators to configure the pump for either higher pressure or higher flow depending on the plunger diameter and gear ratio selected. This makes it well suited to applications where operating requirements vary and a single fixed duty point would be too limiting.

Its seawater-compatible materials, compact drive options, and robust mechanical construction make it a strong choice for offshore and industrial environments where reliability, service life, and installation flexibility are important. The option to step into even higher pressure configurations through the Ultrabar 30 range also adds useful scalability.

Performance Range

The performance table on page 2 shows multiple configurations depending on plunger diameter, gear ratio, and input speed. The available plunger diameters are 26 mm, 30 mm, 40 mm, 50 mm, and 55 mm, with maximum pressure reducing as plunger size increases and flow rising accordingly. The same table notes that flowrates are theoretical and reduce by approximately 7.5% at full pressure, with an 80 mm pump stroke.

Example Operating Points

These figures are taken from the upper performance range shown in the page 2 table, which illustrates the HP220’s wide operating envelope across different plunger and speed combinations.
