FAQ
Questions buyers ask
Why is it mounted outside?
So the metal parts stay out of the corrosive liquid. Only the PTFE and ceramic parts are wetted.
What do you need from me to quote?
Shaft size, speed, temperature, pressure and the fluid. A photo of the old seal or its nameplate helps.
How long does delivery take?
After order confirmation: 2 days from stock, 2 weeks for a new seal.
