Sometimes called “barrel pumps” due to the cylindrical shape of their outer casing, BB5 pumps are high-pressure pumps with three or more impellers. As injection pumps they pump pressurized fluid into the reservoir rock to pressurize the oil and extract it. As charge pumps in oil refineries they put fluids under high pressure to transfer them to various reaction columns. To create this high pressure, BB5 pumps have impellers in multiple stages, and specifications may call for high-speed rotation in the range of 4,000 – 7,000 rpm. Literally the pumping “hearts” in oil-extraction and refining operations, they are the most important pumps in these plants. Advanced technology allows them to operate continuously at extreme temperatures and pressures without leaking. The SNM Model BTBF pump offers just such reliable, continuous operation under extremely harsh conditions.
VS6 pumps are vertically suspended with the rotor perpendicular to the installation surface. The main use of the VS6 is in the transport of low-temperature fluids (e.g., -104 ℃ ethylene) and highly volatile and flammable fluids in oil refining, petrochemical, and gas processing applications. To create high fluid pressures, VS6 pumps may have up to twenty impeller stages. VS6 pumps also feature advanced technologies to prevent leaks of hazardous materials while maintaining safe, continuous operation. The SNM Model CZ pump offers just such reliable, continuous operation under extremely harsh conditions.
SPEC (Shell Pre-Engineered Equipment Catalog)
A major company in the oil and gas industry, Shell has established the Shell Pre-Engineered Equipment Catalog (SPEC), the only such catalog recognized in Asia (four catalogs in total are recognized around the world). Recognized SNM models include NSI (OH2), HDV (BB2), RTV (BB2), SD-S (BB1), and HTB (BB3).
