HMD Sealless Magnetic Drive Vertical Inline Pump
The vertically mounted General Service Petroleum Vertical (GSPV) inline centrifugal pump combines our API 685 expertise with all of the benefits of a magnetic drive sealless pump in a compact package.
- Flows to 1,000 gpm (230 m³/hr)
- Heads to 400 ft (120 m)

Requiring minimum floor space due to its exceptionally small foot print, the GSPV vertical pump meets all of the requirements of API 685, making it ideal for chemical, petrochemical, as well as oil and gas applications, especially those where space is at a premium, such as on offshore oil and gas installations.

Utilizing our significant expertise in meeting API 610 and API 685 standards, the GSPV vertical centrifugal pump avoids the need to accept any deviations. With nine hydraulics and a wide operating envelope of up to 580 psi (40 bar), plus optional design pressures up to 1,450 psi (100 Bar), the GSPV is suitable for many applications.

HMD have been building sealless magnetic drive pump units for the oil and gas industry since 1983. Their API-685 line of sealless magnetic drive, end suction centrifugal pumps comply with specifications required by the oil, gas, petroleum and heavy chemical industries, including these vertically orientated GSPV units, thus increasing the application scope for this technology.
