Matre Wide Range Balanced Foam Proportioners (M-BWP60) are known for their reliability.

Pressurized water within the performance range and foam is what is required for a perfect proportioning. Our range of M-BWP are used in pressurized foam pump system designed for both sprinkler systems, foam monitor applications as well deluge systems.

Our Wide range balanced pressure proportioner will be deliver with a fixed foam insertion rate of 1-6% AFFF that will be pre-set during manufacturing of the proportioner.

Our range of M-BWP will gain an accurate foam insertion, irrespective of variation of pressure and water flow.  The accurate performance of our M-BWP is important to guaranty the correct foam insertion rate to be feed into the system water line.   

All units will be performance tested before delivery, as well as delivered with a unique test report when indicating the foam insertion over the complete wide range.  

See our standard data sheet for more information.
