Osmolator pump used with kalkwasser?

[Vital Idol]

Can the osmolator pump be used with kalk water? or will it clog or damage the pump?

[rvitko]

It will clog and damage the pump and voids the warranty of the pump, however the pumps are cheap and if you use a low dose and make sure the pump is suspended so powder cannot enter it will probably last almost a year.

I have been using the Tunze Osmolator pump to doze kalk makeup water (2 tsp/gallon) for 11 months and have not had a problem with the pump. I have the pump about 3" off the bottom of the kalk water tank to keep the sediment from being pumped. The pumps are pretty cheap. I bought a couple for replacement when mine eventually fails.
