The CRVpro16 pump is cUL listed(E485334).
The CRVpro16 pump with explosion proof motors comes with the following key features:
- reduced risk of chemical attacks and oil breakdown by diluting chemical vapors with a larger oil chamber
- slowing down corrosion by cool running operation
- provides a measure of protection from sublimed chemical vapors with coating on pump module and oil case.
These benefits lead to extended service interval.
