PMC’s high-output GH-40 in various configurations are the industry flagships. PMC has managed to create an ultra-reliable system which builds on the now classic horizontal pump line with PMC’s engineering quality. Extremely robust yet simple pump design keeps downtime to an absolute minimum, while generating profits for its owner. A long list of features, help the foam mechanic maintain peak productivity even in cold weather applications. Customers, who have acquired these systems from NuVERSA, one of the premier PMC distributors, have deployed these machines in many places from all over North America to Asia, Africa and other far flung locations.

Polyurethane foam machines fulfill three functions:
a) Maintain the ratio of the foam (most often 1:1)
b) Heat the two components to optimal temperatures (usually 100 to 130 degrees).
. The two components may be heated to different temperatures if the two components
have different viscosity curves,
c) Maintain pressure, typically between 950 and 1400 psi depending on the foam.
The machines are usually max. rated 2000 psi for foam and 3500 psi for coatings.

Other interesting facts: this particular machine can spray up to 40 lbs./minute which is a rather massive quantity of foam. More importantly, GH-40 includes 18,000 watt pre-heaters which allows 40 lbs./minute to be heated to the required temperature.

Of course, the foam mechanic or sprayer needs to be quite skilled to lay down that much foam and make it look nice. Most often, sprayers produce about 15 to 25 lbs. of foam.
