Two stage liquid ring pumps

close

Overview

SIHI twin stage vacuum pumps are two-stage displacement pumps of uncomplicated and robust construction with the following particular features like handling of nearly all gases and vapours, non-polluting due to nearly isothermal compression, oil-free (no lubrication in the working chamber), small quantities of entrained liquid can be handled, easy maintenance and reliable, low noise and nearly free from vibration, wide choice of material (therefore applicable nearly everywhere), incorporated central drain and no metallic contact of the rotating parts.

Overview LPH / LPH-X Series LEH Series LOH Series

SIHI two stage vacuum pumps

Applications:
Handling and exhausting of dry and humid gases. Entrained liquid can be handled during normal duty. The pumps are applied in all fields where a pressure of 120 to 900 mbar must be created by robust vacuum pumps. Fields of application are for example the chemical and pharmaceutical industry (distilling and degassing), the electric industry (impregnation and drying), the plastics industry (degassing) and many more.
