The Little Giant TE-4-MD-HC Series Magnetic Drive Pump is a seal-less chemical transfer pump designed for handling corrosive liquids, acids, alkalis, solvents, plating solutions, and industrial process chemicals.
Engineered with a magnetic drive system, the TE-4-MD-HC eliminates conventional mechanical seals, reducing leakage risks and improving reliability in chemical transfer applications. The pump is designed for in-line, non-submersible operation and is widely used in industrial chemical handling systems, laboratories, wastewater treatment facilities, plating plants, and process industries. (Little Giant)
The Little Giant TE-4-MD-HC Series is commonly selected for applications requiring corrosion resistance, low maintenance, and safe transfer of aggressive liquids.
About Little Giant TE-4-MD-HC Series
The Little Giant TE-4-MD-HC Series belongs to the MD-HC family of magnetic drive centrifugal pumps designed specifically for highly corrosive chemical applications.
The pump utilises a leakproof seal-less magnetic drive design that prevents direct shaft penetration into the liquid chamber. This construction helps reduce maintenance requirements while improving operational safety in chemical environments. (Little Giant)
Its chemical-resistant construction includes glass-filled polyphenylene sulfide (PPS), ceramic shaft components, and FKM O-rings for enhanced compatibility with aggressive liquids. (Little Giant)
