SIHI Single-Stage Liquid Ring Vacuum Pumps

Pumps Flowserve

The SIHI Single-Stage Liquid Ring Vacuum Pumps are robust, oil-free pumps engineered for handling a wide range of gases and vapours. With suction capacities from 1500 to 5050 m³/h and pressure ranges from 120 to 1013 mbar, these pumps are designed for reliable performance in demanding industrial applications.

Featuring simple, low-maintenance construction and the ability to handle small quantities of liquid carryover, they are ideal for distillation, degassing, drying, and impregnation processes. The single-stage design ensures efficient operation with reduced noise and vibration levels, making them suitable for a variety of industries, including chemical, pharmaceutical, and plastics manufacturing.
