Volm VMB05 Double-Casing Multistage Centrifugal Pump in 200 kt/a Alkane-Aromatic Unit Volm VMB05 Double-Casing Multistage Centrifugal Pump in 200 kt/a Alkane-Aromatic Unit In petrochemical processing, 200 kt/a alkane-aromatic units are pivotal for heavy oil upgrading and high-value chemical production. The hydrogenation feed pump, as the "heart" of the unit, must deliver explosive mixtures of high-pressure hydrogen and feedstock (e.g., wax oil, residue) to reactors at 8.5 MPa. Original canned motor pumps failed during commissioning, exposing critical flaws. Volm's VMB05 double-casing multistage centrifugal pump resolved these limitations through engineered innovation.

Low-Flow High-Head Solution Powers CO₂ Electrolysis for Syngas Production Low-Flow High-Head Solution Powers CO₂ Electrolysis for Syngas Production In a national-level CCUS demonstration project converting industrial CO₂ to syngas (CO+H₂), the makeup pump system faced extreme challenges: ≤28 m³/h flow, 400m head, NPSHA≤2.0m, and media containing solids. Traditional multistage/high-speed pumps suffered from low efficiency, frequent maintenance, and cavitation risks. Volm’s VMH03X series pumps delivered a customized solution. View details
