STMMC Multi Stage VS4 Submersible Pump Long Shaft

STMMC Multi Stage VS4 Submersible Pump Long Shaft belongs to Submersible Magnetic Pump Series. It delivers stable Zero leakage magnetic pump solution for deep‑pit and sump conditions and serves as Magnetic pump for hazardous media for tank‑borne dangerous fluids. Designed per API 610 VS4 vertical long‑shaft suspended layout and API 685 magnetic‑drive standards, its pump end is submerged while motor stays at grade level. Customizable column length enables variable submersion depth with no pre‑priming required. Widely deployed in petrochemical tank farm, coal‑chemical and chemical sump services, it handles high‑head, toxic, flammable‑explosive and corrosive fluids. Magnetic‑coupling sealless design eliminates mechanical dynamic seals with full static‑seal construction, fundamentally removing leakage risks and preventing safety and environmental hazards caused by hazardous fluid spillage. Multi‑stage impeller assembly delivers high‑head performance. Built‑in thrust‑balance mechanism p…
