SIHI ISOchem Pump Series, CBS, CBM and CBE
The SIHI ISOchem range is a modular family of horizontal, single stage chemical process pumps with ISO 2858 dimensions and designs aligned with ISO 5199 requirements. Built for aggressive media handling, the ISOchem series supports multiple sealing concepts, including mechanical seals and magnetic drive options for leak reduction in critical services.
With proven hydraulics and a modular back pull out concept, SIHI ISOchem pumps help reduce downtime, simplify maintenance, and improve lifecycle cost in harsh process environments.
Models in the SIHI ISOchem Series
SIHI ISOchem Pump CBS
The CBS model is a chemical process pump configuration used across demanding process duties where stable performance and corrosion resistant materials are required. It is commonly selected for continuous plant operations involving aggressive liquids and process reliability requirements.
SIHI ISOchem Pump CBM
The CBM model is designed around modular maintenance and serviceability. The interchangeable back pull out assembly concept helps shorten service time and supports uptime focused operations in chemical and petrochemical facilities.
SIHI ISOchem Pump CBE
The CBE model is often specified for higher containment and safety driven duties through seal system choices, including magnetic drive solutions, supporting reduced leak risk in sensitive chemical services.
