 and polyol temperatures. The series comprises two hydraulic proportioning models with output capacities of 25 and 50 lb/min at 2000 psi pressure.

A new hydraulic pump is said to eliminate pressure fluctuation during piston changeover and to deliver consistent spray pressure. Field experience shows that Reactor IPH pump seals have an average life 10 times longer than standard systems.
