Stainless Gear Pump With Magnetic Seal

Constructed from SUS304 or SUS316L stainless steel, with gears and bushings available in materials such as PEEK or 440C, the pump is designed for the precise metering and transport of corrosive, flammable, explosive, toxic, or high-value media. As a positive-displacement external-gear pump, its flow rate is linearly proportional to its rotational speed; it can be paired with a variable-frequency drive (VFD) or a servo motor to ensure stable flow and excellent metering repeatability. Ideally suited for clean, low-to-medium viscosity chemical media, it is widely used in sectors including fine chemicals, pharmaceuticals, inks, resins, additives, and fuel handling. The design effectively eliminates leaks, spills, and drips, thereby reducing both maintenance requirements and safety risks.

FAQ:

Q: Is it truly leak-free?

A: Yes, no dynamic shaft seal, only static O-ring seal.

Q: Can it run dry?

A: No, dry running will damage gears and bearing.

Q: What viscosity range?

A: Normally 0.5–15000 cP, suitable for clean liquids without solid particles.

Q: Can we use servo motor?

A: Yes, servo / stepper / explosion-proof motor optional.
