The GSPLF OH2, is a low flow center line mounted single stage sealless magnetic drive pump with relatively high head capability that is API 685 and ATEX compliant.

The OH2 sealless magnetic drive pumps have a single bearing housing to absorb all forces imposed upon the pump shaft and maintain rotor position during operation. The pumps are mounted on a base-plate and are flexibly coupled to their drivers. It is ideal for oil and gas installations, plus chemical and petrochemical applications.

Heads to 490 ft (150m)
Flows to 132 gpm (30 m3/hr)
Temperature Range: -40 to 500 F (-40 to 260 C)
Standard Design Pressure: 580 psi (40 Bar)

Filling a gap in the market for a low flow sealless pump with a relatively high head capability, the GSPLF pump combines the proven technologies of Sundyne Barske Wheel hydraulics with sealless magnetic drive pump components.
