Hughes Pumps Ultrabar 30 UHP Pump | Ultra High Pressure Pump up to 2800 Bar

The Hughes Pumps Ultrabar 30 UHP Pump is an ultra high pressure plunger pump designed for demanding industrial pressure applications. It is rated up to 2800 bar at 33 lpm and can deliver up to 44 lpm at 2000 bar, making it a strong option where extreme pressure is required alongside dependable mechanical design. The maximum performance figures are highlighted on page 1, with the broader operating envelope shown in the page 2 performance table.

A key feature of the Ultrabar 30 is its alloy steel modular pumphead, which allows seals and valves to be monitored without tools and supports maintenance on individual cylinders. This can help simplify servicing and reduce downtime in high pressure operations where maintainability is important.

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, creating a compact, aligned installation while enclosing moving parts. The Ultrabar 30 can also be supplied as a bareshaft pump only or as part of a complete unit build.

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

The datasheet also lists options such as a UHP pressure gauge or pressure transducer, burst disc, and solid tungsten carbide or ceramic plungers with floating crosshead attachment and self-adjusting seals. The page 1 feature summary also notes outstanding seal, plunger, and valve life.

The 14 mm plunger version uses the splash lubricated HP120 power-end, and the datasheet notes that the Ultrabar 30 is convertible to 1000/1400 bar, with reference to the HP220 data sheet.

Why Choose the Hughes Pumps Ultrabar 30 UHP Pump?

The Ultrabar 30 is designed for applications where pressure is the priority. The performance table on page 2 shows operating points across 14 mm, 18 mm, and 22 mm plunger diameters, with maximum pressure reaching 2800 bar on the smaller plunger sizes and higher flow rates available at 2000 bar on the larger configuration.

Its modular pumphead design is also a notable advantage. Being able to monitor seals and valves without tools, and work on individual cylinders, can make a real difference in demanding UHP service environments where access, uptime, and service efficiency matter.

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 14 mm, 18 mm, and 22 mm. The table notes that flowrates are theoretical and reduce by approximately 10 to 12.5% at full pressure, with an 80 mm pump stroke. Page 2 also notes that the P14 build uses the HP120 power-end.
