Electric Spray Foam Pump Systems

There are three types of spray foam machines from which to choose – electric, air driven and hydraulic. Each has its advantages depending on your spray Foam Pump(KEXON) needs and how you plan to use your equipment.This article explains how electric spray foam machines work and some things to consider before buying one.
Electric spray foam machines provide good performance for a wide range of applications, particularly if high throughput is required for the job. These systems are designed for use with fast-setting polyurethane two-component foam and polyurea coatings.These systems are based on electric motor and pump technology that has been used in the industry for many years. In high-quality electric spray foam systems, motor control technology precisely controls these motors, because they must maintain consistent pressures when the applicator trigger is pulled (dynamic pressure), and when it is not pulled (stall pressure).
The motor control technology monitors fluid pressure and regulates electrical current to the motor. Pressure monitoring also is used to ensure the two pumps maintain the proper ratio. Because the two pump pressures must be about the same in order for the proportioner to produce a 1:1 chemical ratio, the pumps and applicator orifices are equally sized. ?If the pump pressures go out of balance, state-of-the-art systems will automatically shut down in order to prevent the operator from spraying bad foam or coating. The operator also receives a message indicating the reason for the shutdown, so the problem can be corrected.
