Industrial / chemical resistant teflon lined magnetic drive pump
stainless steel deep well pump
,magnetic drive pump
Economic and Reliable Design Features
- 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.
- Anit-corrosive
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.
- Low maintenance costs and long service life.
Cost-intensive wearing parts are canceled by the seal-less method of construction, therefore, reduced maintenance costs and long service life. The structure is tightly, safety, and energy-saving.
Design Pressure: 1.6MPa
