Large-Flow Stainless Steel Magnetic Pump QWW Series

Material	SUS304 / SUS316
Flow	250–830 L/min ( 15–49.8 m³/h )
Head	18–48 m
Temperature	-196~420 ℃
Power	1HP-15HP

Product Description

QWW Series is a stainless steel magnetic pump for larger-flow process circulation and transfer. It is intended for users who need stainless wetted material and a sealless pump structure for compatible industrial liquids, while requiring more capacity than compact stainless models.

The series is suitable for alkaline liquid, organic solvent, oil liquid, and similar process media where leakage reduction, stainless construction, and stable circulation are important. It is a practical option for production lines that need a balance of higher flow and magnetic-drive safety.
