Bunan sesibility to chemicals
(OP)
We are buying a progressive cavity pump for prod. water (from an oil field). I was not involved in specifying the pump but has now discovered that it was not mentioned that the prod. water will contain various chemicals such as MeOH, TEG, emulsion breaker, scale inhibitor...
Anybody got experince that indicates that one should be carefull with regards to material selection for the stator? Currently its high desity bunan.
Best Regards

It is recommended not to use for chemicals viz., Methyl ethyl ketones, methyl acetone, acetone, Formaldehyde, ethyl acetate, Isopropyl acetate, amyl and butyl acetates, Benzene, toluene, xylene, benzol, hexane, napthalene, cyclohexane, CTC, trichloroethylene, EDC, methyl and propyl chloride and chloroform.
Apart from exhaustive list of chemicals I mentioned few which are pinpointed in the guide.

Third parties have limited ability to provide really accurate information about how a particular elastimer will perform in a progressing cavity pump. In a PC pump the elastimer is constantly "wiped" and variably stressed which is quite different from say an "O" ring. The chemical compatibility of the elastimer is affected by these conditions in some applications.

All you can do is look at the chemicals that are most likely to be in this particular sample, choose the rubber compatible with these and proceed with the installation. There are no guarantees.
