Powerful high pressure pumping
Hughes Pumps have taken this even further and have a proven track record in supplying high pressure pumps for use subsea, mounted to ROV’s (Remotely Operated Vehicles) and used up to 3000m (10,000 ft.) subsea. The pumps are used for cleaning, cutting and trenching applications as well as pumping Ethylene Glycol (MEG). It is not possible for divers to work at such depths, nor is it practical to run high pressure hoses from the surface to such extreme depths. Mounting the pump on the ROV maximises the e ciency of the pump as there is no pressure loss in high pressure hoses.
Hughes Pumps has pump technology to 3000bar
An hydraulic motor is close coupled to the pump crankshaft via a lightweight, anodised aluminium bell housing and exible drive coupling making a very compact, lightweight installation.
Key to the company’s success with this specialist application is modifying standard pump materials to provide adequate corrosion protection and preventing seawater from breaching the crankcase oil seals and contaminating the lubricating oil. At 3000m depth the ambient seawater pressure is 300bar (4,350psi) which requires some complex engineering to protect against. The pump range is available at up to 3000bar and 375kW (43,500psi and 500hp).
