Application Fields
Biological medicine, petrochemical, mining, metallurgy, textile printing and dyeing, electricity, food, papermaking, electroplating, sewage treatment, flue gas treatment, new energy, new. materials and other industries.
Pump Usage
Applicable to transport inflammable and explosive volatile, poisonous and harmful, valuable and highly corrosive cleaning medium; Such as any concentration of acid and alkali, salt, solvent, strong oxidizer, etc.
Design Instruction
NMQEW (direct connection with two insulation), NMLEW (split with two insulation), and NMLSW (three insulation) are insulation magnetic pumps
developed according to the user's requirements for conveying the medium that is easy to crystallize. They can convey both high-temperature and low-temperature media. This series of magnetic pumps continues the advantages of high-temperature magnetic pumps. The medium must be conveyed within the
specified temperature range. The unique new insulation structure is adopted to keep the medium flowability during the transmission, and avoid condensation,
crystallization, vaporization,n and other phenomena due to temperature variation; the corresponding insulation and cooling methods are adopted for the driving part according to different working conditions to ensure that the driving part will not be affected by the temperature of the transmission medium.
