Oceaneering has designed and built a range of Duplex Piston Pumps. These pumps are based upon a reciprocating piston intensifier with fixed displacement. Hydraulically powered by the host Remotely Operated Vehicle (ROV), the pumps are available in two sizes, the 15 hp Series and the 50 hp Series, with a wide range of pressure ratios available in each series. The pumps are the basis for multiple tooling applications, including subsea hydrotesting, hydrate remediation, and general fluid intervention. The pumps are not compatible with methanol. For methanol-compatible pumping, use the Duplex Plunger Pump.
