SIHI dry pump

A completely dry running vertical twin-screw machine with no mechanical shaft seals. Designed for chemical, pharmaceutical, and industrial applications requiring uncontaminated vacuum, free from oil or service liquids.

+ Lower life cycle cost made possible by dry operation, eliminating service liquids, lubrication and waste disposal costs

+ Increased energy efficiency from intelligent drive system that performs ongoing rotor diagnostics while optimizing speed and pressure control

+ Increased personnel safety enabled by low-noise, gearbox-free operation (all models), plus explosion-proof design for chemical and pharmaceutical models
