Production introduction
The foinbo® Dual Electric Motor Foam Proportioning System delivers unmatched reliability for industrial fire safety, built with two independent motor units to eliminate single-point failure risks. Powered by twin electric motors, it maintains continuous foam mixing even if one unit experiences downtime or maintenance. Its balanced pressure mechanism dynamically adjusts foam concentrate flow, holding a consistent 3–3.9% mixing ratio regardless of water flow fluctuations. Rated for 1.2MPa working pressure, it supports mixed liquid rates from 8–250 L/S across PHP32 to PHP250 models, making it suitable for facilities that demand zero downtime fire protection.
This system stands out for its robust build and low-effort operation. It uses stainless steel gear pumps to handle foam concentrate, resisting corrosion and ensuring long service life even with harsh foam agents like protein, fluoroprotein, and aqueous film-forming foams. Paired with a vented, bladderless foam tank, maintenance is simplified, and the system supports refilling foam concentrate mid-operation for extended emergency response. The automatic/manual control mode offers flexible operation, while pressure relief and holding valves keep working pressure stable throughout the process. Standard DN100–DN300 flanged connections ensure smooth integration into new or existing fire networks.

Products Description
FAQ
Q: How does the dual electric motor setup improve reliability?
A: Two independent motors ensure continuous foam mixing; if one motor fails or needs maintenance, the other takes over instantly, eliminating single-point failure risks.
Q: What foam concentrate types is this system compatible with?
A: It works with protein, fluoroprotein, aqueous film-forming (AFFF), and alcohol-resistant (AR-AFFF) foams, supporting most standard foam agents for diverse fire hazards.
Q: Can foam concentrate be refilled during operation?
A: Yes, the system allows adding foam concentrate mid-operation, making it suitable for extended emergency response in large-scale fire events.
Q: What flow and pressure ranges does this system support?
A: Rated for 1.2MPa working pressure, models span PHP32 (8–32 L/S) to PHP250 (8–250 L/S), catering to small to large facility sizes.
Q: What control modes are available for the dual-motor system?
A: It supports both automatic and manual control modes, allowing flexible operation during routine checks and emergency scenarios.
