Engineered to Perform in Tough Applications
The heavy-duty construction of our Lewis® vertical sulphur pumps eliminates shaft sealing problems generally associated with horizontal pumps requiring a pressurised stuffing box or seal, ensuring both environmental protection and operator safety.
Heavy-duty Construction
The heavy-duty vertical pump construction is designed for applications involving heavy (1.8 specific gravity) fluids resulting in smooth, vibration-free operation at all points on the pump curve.
Self-lubricated Line-Shaft Bearings
Where provided, line-shaft bearings are self-lubricated by the molten sulphur being pumped, eliminating the problems and unreliability of an external lubrication source.
