Frequently Asked Questions

Magnetic pumps use magnetic drive coupling with no mechanical seal, achieving zero leakage. This makes them superior for handling toxic, flammable, expensive, or environmentally hazardous fluids where even minor leakage is unacceptable. No seal maintenance or replacement is needed.

Self-priming pumps are ideal for: chemical transfer between tanks, wastewater sump pumping, underground tank emptying, plating solution circulation, portable pump stations, and applications where the pump is located above the liquid level.

Ordinary pumps use cast iron or standard steel for wetted parts, suitable only for water or mild fluids. Corrosion-resistant pumps use engineered thermoplastics (PVDF, PP, PEEK), stainless steel alloys, or exotic metals (Hastelloy, titanium) specifically selected to resist chemical attack.

Most corrosion-resistant pumps are centrifugal: an impeller rotates to create centrifugal force, accelerating the fluid outward and generating pressure at the discharge. The impeller and wetted components are made of corrosion-resistant materials to handle aggressive chemicals.

Novice users should:
1) Read the operation manual thoroughly,
2) Understand basic pump components and their functions,
3) Learn proper startup/shutdown procedures,
4) Know the fluid being pumped and its hazards,
5) Recognize abnormal sounds or vibrations,
6) Follow scheduled maintenance checklists.

Classified by:
1) Material (PVDF, PP, stainless steel, Hastelloy),
2) Structure (centrifugal, self-priming, magnetic drive, vertical),
3) Seal type (mechanical seal, magnetic drive, gland packing),
4) Application (chemical transfer, filtration, dosing, wastewater).
