General Service Petroleum Vertical API 685 Sealless Magnetic Drive Pump

A compact, vertical sealless magnetic drive pump for safe processing and handling of hazardous and valuable hydrocarbons and chemicals The GSPV range of vertical pumps caters to a variety of applications such as booster packages, condensate transfer, hydrocarbon transfer and sampling packages. Its compact design particularly lends itself to offshore applications where space is at a premium. The use of fixed diffuser parts outboard of the impeller instead of a volute casing optimized the best efficiency point and allows variation of the head rise to shut-off for a range of duty points. Each hydraulic is offered with at least two diffuser options. The diffuser may be changed in situ, without removing the casing from the process, should pump duty change significantly. Flows up to 1,250 GPM (285 m³/hr) Heads to 430 ft (130m) Temperature Range -40 to 400°F (-40 to 205°C)

A major advantage of having a diffuser is a significant reduction in radial loads and the consequential low vibration levels experienced and stabilization of the characteristic head curve.

The rigidly coupled vertically mounted design has nine hydraulics split between two frame (magnetic coupling) sizes to suit the power requirements, with the option of  ZeroLoss shells in all configurations.
