Why SPX FLOW TG GP58-80 has no flow?

If your SPX FLOW Water Pump has no flow, it might not be priming due to several reasons. The suction lift could be too high. Reduce the difference between the pump and suction tank level, or increase the suction pipe diameter, or reduce the length and simplify the suction pipe. Check for air leaks in the suction line and repair them. If the viscosity is very low, increase the pump speed and reduce axial clearance. Ensure the suction strainer or filter is clear. Verify the pump casing is correctly installed. Finally, check the motor's rotation; for 3-phase drivers, switch two connections, or change the suction and discharge opening, but be careful to check the location of the safety relief valve.
