What is the difference between the maximum fluid working pressure and the maximum spray pressure for an E-10hp?

When selecting the appropriate E-10hp plural component proportioner for spraying foam and polyurea, you must take into account the most important system specifications. Understanding the difference between the maximum fluid working pressure and the maximum spray pressure is a good way to start your selection.

There are many different plural component proportioners for spraying foam and polyurea. Selection of the appropriate reactor for your application depends on several aspects. Two important specifications to consider are the maximum fluid working pressure and the maximum spray pressure. These parameters are often confused with each other, yet they are totally different. In this article we will clarify their meaning and difference once and for all.

 

What is the maximum fluid working pressure for E-10hp?

The maximum fluid working pressure refers to the maximum pressure the machine is capable of producing under a stall. (206 bar, 3000 psi).

 

What is the maximum spray pressure for E-10hp?

The maximum spray pressure refers to the dynamic spray pressure of the machine which is dependent upon the power available due to machine voltage (120V or 230V).  The machine is capable of generating the maximum spray pressure continuously at the maximum flow rate of 3.7 lpm (1 gpm) while spraying. A system on 230V will have a higher maximum spray pressure than a system on 120V. For example: the maximum spray pressure of a Reactor E-10hp is 150 bar (2,200 psi) for 120V units and 172 bar (2,500 psi) for 230V units.
