Rotary Power chemical metering pumps are suitable for use on all types of polyol blends and all types of isocyanates. Rotary Power pumps have been applied with TDI, MDI and TDI/MDI mixes, as well as, with polyether and polyester resins and methylene chloride. Additionally, the C04, C07 and C20 were specifically designed for the future when CFC’s are banned and other blowing agents will be used.

The C04 pump can be adjusted accurately from 0 – 6.0 cm3/rev, the C07 from 0 – 11.5 cm3/rev, and the C20 from 0 – 33 cm3/rev. The hand wheel control incorporates a dial indicator which shows the pump’s setting at a glance.

Contact MHR, Inc. for assistance in selecting a new chemical metering pump or for repair of an existing chemical metering pump.
