Stainless Steel Magnetic-Drive Thermal Insulation Gear Pump
Stainless Steel Magnetic Jacketed Gear Pump integrates magnetic‑drive leak‑free structure and thermal‑insulation jacket. The pump body is made of 304 / 316L stainless steel. Hot oil or hot water circulates inside the jacket to keep medium temperature and prevent material solidification.
Adopting magnetic coupling transmission instead of shaft seal, it achieves zero leakage.
Equipped with precision gear pair for stable flow output, it is ideal for dosing & transfer of toxic, flammable‑explosive, corrosive, high‑viscosity and easy‑to‑solidify media.

Main Features
Magnetic leak‑free drive: Magnetic coupling design, no shaft seal, eliminate medium leakage completely.
Jacket thermal insulation: Circulating heating medium keeps constant temperature, avoid material coagulation and pump blockage.
Stainless steel material: 304 / 316L stainless steel body, excellent corrosion resistance.
Precise metering: High‑precision gear set, flow adjustable by rotating speed, stable dosing performance.
Low‑maintenance: No wearing shaft seal, reduce failure risk and maintenance cost.
Flexible drive options: Servo motor or VFD motor available for accurate flow control.
Application
Fine chemical, pharmaceutical, resin, asphalt, adhesive, solvent, polymer material. Especially suitable for media requiring zero‑leakage: toxic, volatile, flammable‑explosive, easy‑solidification fluid.
