The GSPX magnetic drive pump is a multi-stage, API 685, BB5 design using between bearings design for the second and third stage impellers. This pump that is ideal for oil and gas installations, plus chemical and petrochemical applications.

Heads to 1400 ft (295m)
Flows to 440 gpm (62 m³/hr)
Temperature Range: -40 to 500 F 
      (-40 to 260 C) Standard
Max Case Pressure up to 725pia (50 Bar)

Based on our proven magnetic drive, it is available in 2 or 3 stages with two diffuser based hydraulic options. The GSPX produces higher differential pressures than our single-stage sealless models, while offering reliable, safe, leak-free handling that you expect from our flagship API-685 sealless magnetic drive pumps.
