Maximize Reliability with Liquid Ring Vacuum Pumps & Systems
Many industrial processes depend on a stable vacuum source for operations like distillation, drying, or vapour recovery—but conventional pumps often struggle under aggressive chemical conditions or high vapor loads. Frequent maintenance, temperature fluctuations, and inconsistent vacuum performance can disrupt production and raise operational costs.
SCG Process provides FLOWSERVE SIHI® Liquid Ring Vacuum Pumps and Systems engineered for reliable, continuous operation in demanding environments. With a robust design and superior materials of construction, these pumps perform efficiently even in the presence of corrosive gases, vapours, and contaminants.
Why Choose SCG Process for Vacuum Solutions?
Reliability: Designed for continuous operation in harsh industrial environments.
Performance: FLOWSERVE SIHI pumps deliver proven, high-efficiency vacuum and compression capability.
Customization: SCG Process engineers tailor each system to meet precise performance and site requirements.
Support: From design to installation and service, we provide complete lifecycle support to ensure system uptime and longevity.
Engineered for Tough Vacuum Applications
The FLOWSERVE SIHI® range of liquid ring vacuum pumps is built for performance in challenging industrial applications where reliability, efficiency, and safety are critical. Available in single- and two-stage designs, these pumps deliver suction capacities up to 12,000 m³/h (7,063 cfm) and operate efficiently at pressures from 33 mbar to 1013 mbar—without the need for additional boosting equipment.
They can also be configured as liquid ring compressors, generating positive pressures up to 13 barg (188 psig) for air or gas compression.
SCG Process supplies these units as standalone pumps or as part of pre-engineered or custom vacuum systems, tailored to meet your exact site and process requirements.
Central Vacuum and Housekeeping Systems
Facilities often need efficient, centralized vacuum power for multiple operations, from cleaning to material transfer—yet scattered or outdated systems can waste energy and limit reach.
SCG Process designs and installs custom central vacuum systems featuring Spencer vacuum producers, separators, and collectors, connected through a durable metallic tubing network. These systems extend vacuum capability across your entire facility, offering high suction power, energy efficiency, and adaptability for a wide range of industrial and commercial uses.
