-Leak-proof design.

-Sealless Teflon lined magnetic drive pump, driven by magnetic coupling indirectly, motor shaft and pump chamber is completely sealed, avoid pump leakage problem and use site pollution.

-Wetted part material is PTFE fused with FEP, can transfer low and high concentration acid, alkali, strong oxidizer etc corrosive liquid.

-Robust pump casing. The part contacting with liquid material is fluoroplastic, pump casing material is cast iron, and pump casing can bear part of piping and mechanical impact.
 -The structure is tightly, safety, and energy-saving.
 -Cost-intensive wearing parts are cancelled by the sealless method of construction, therefore, reduced maintenance costs and long service life.
