Procurement of Fluorine Lined Magnetic Drive Pumps and Centrifugal Pumps for 1203U Unit

2024-11-22 00:00:00

Hubei Xianjing Technology purchased 37 fluid transfer pumps (fluorine lined magnetic drive pumps, fluorine lined centrifugal pumps, metal magnetic drive pumps) for transferring corrosive, flammable and explosive media (e.g. butanone oxime, hydroxylamine hydrochloride, etc.) in the 1203U plant.

Project brief

Industry	Chemical (fine chemicals, hazardous media transportation)
Media	Aqueous oxime salt solutions, butanone, butanone oxime mixtures, aqueous hydroxylamine hydrochloride solutions, methyltris-butanone oxime silane (highly corrosive media)
Flow rate	2~50 m³/h
Head	10~80 m
NPSHr	1.5 to 3 m (according to pump model)

Special working conditions, pain points and solutions

Special working conditions	Pain Points	Solutions
Highly corrosive media (hydrochloric acid, butanone, etc.)	Conventional materials are susceptible to corrosion, resulting in leakage and equipment failure	Material upgrade: Fluoroplastic (F46) lining Silicon Carbide for shaft system (corrosion and wear resistant) Magnetic drive design: Elimination of dynamic seals for zero leakage
High temperature/high pressure service conditions (some media temperatures up to 80°C)	High temperature leads to accelerated bearing wear and reduced efficiency	Cooling channel design: Internal circulating lubrication to remove heat. High temperature resistant material: samarium cobalt magnet (350°C non-demagnetization).
Flammable and explosive environments	Traditional seals are prone to leakage, causing safety hazards	Totally enclosed magnetic drive: eliminates leakage points BT4 explosion proof motor: meets GB/T 3836 explosion proof standard
High frequency start/stop (intermittent operation)	Frequent starting and stopping leads to shortened bearing life	Axial force self-balancing technology: reduces start-up shock Soft start configuration recommendation: reduces mechanical loads
