PSIL molten sulphur pumps feature:

• Stiff shaft, 60mm diameter construction
• API 610 figure-32 maximum spacing between shaft guide bearings as a minimum standard
• • Line-shaft bearings with fully-floating bushes to balance wear and extend lifespan
• Under-ground line-shaft bearing sleeves with stellite 12-weld overlays, prior to grinding to finished size if the unit is carbon steel
• Extensive steam jacketing, minimising cold spots and enabling sulphur to drain down during servicing
• Open impellers, preventing sulphur blockages by increasing tolerance for entrained solids and gas, while accommodating viscosity variation
• One-piece shafts available up to 4 metres and, for longer applications, two-piece construction would be utilised
• Discharge nozzles rated to loads twice API 610 Table 5
• Circular mounting plates to ANSI B16.5 RF standard or rectangular to suit pit openings

All materials are of dense, homogenous wrought construction – PSIL does not build from castings.
Finishing vertical pump wet ends with stainless steel is increasingly popular, significantly extending the lifespan of pump sets, particularly for sulphur environments.
