Balanced Pressure Proportioner Mk 2
Product catalog summary
General Description: The Balanced Pressure Proportioner (PP) Mk2 is designed to induce foam concentrate into the water feed line, ensuring accurate foam proportioning even with fluctuations in water flow and pressure. It is primarily used in foam pump systems for monitor and deluge systems.
Specifications: The PP series includes models PP-50, PP-80, PP-100, PP-150, PP-200, and PP-250, each with varying capacities and dimensions. All models are made from corrosion-resistant bronze (Cu88Sn12) and can handle a maximum working pressure of 16 bar (235 psi).
Product Features: The proportioners are maintenance-free, reliable, and factory-set to deliver accurate foam proportioning up to 3%. They feature wafer-type water connections and flanged or screw-threaded BSP foam connections.
Connections: Water connections are wafer-mounted between flanges, while foam connections can be flanged to fit DIN or ANSI standards or threaded BSP.
Listings and Approvals: The product is approved by Det Norske Veritas (DNV) and complies with EN 13565-1 standards.
Operation: The proportioner operates automatically within the specified flow range, requiring the foam pressure to be at least one bar higher than the water pressure. It ensures smooth operation of all system valves.
Installation Requirements: A minimum of five diameters of straight pipe is required before the proportioner and three diameters after it.
Order Information: When ordering, specify the size, connection type (DIN or ANSI), and foam concentrate mixing rate.
