Positive displacement foam pumps used in fixed and mobile firefighting systems have unique considerations when the pump manufacturer and/or model numbers need to be updated or changed. As PFAS-containing foams have been removed from the market and replaced with higher-viscosity, Fluorine-Free (SFFF) foams, the pumps currently installed in the system may no longer adequately perform as designed.
Fire Lion Global has unique perspectives with multiple brands of firefighting foam pumps other than Fire Lion Global. Our knowledge and experience with most brands on the market today put us in a very promising position as your partner and solution provider for any retrofit you may see yourself providing.
Ready to start your retrofit project?
Kickstart your firefighting PD pump retrofit project by clicking the link below to download the questionnaire. Since each project has specific requirements and installations, fill out the form as completely as possible. When emailing the completed form back, if possible, please include pictures of all equipment, nameplates, piping designs and overall system installation.
The following list is just some of the engineering considerations that must be made when performing any positive displacement retrofit. It also appears on the first page of the downloadable form.
- Firefighting foam agent type, i.e. AFFF, AR-AFFF, SFFF, etc.
- Suction piping sizes and design.
- NPSHa calculations on current design and future design per NFPA 20.
- Stainer basket hole sizing.
- Pump driver details, i.e. electric motor, diesel engine, hydraulic motor, PTO, water pelton wheel.
- Horsepower requirement of current system and retrofit system.
- System demand for foam concentrate flow rate and pump pressure rating.
- What listings and approvals are required currently and what will be required after the retrofit.
- Pressure Relief Valve (PRV) installation and required set pressure.
- Pump connection size differences.
- Pump dimensional differences between old and new pump models/manufacturers.
- Detailed controller information with options needed for installation location/conditions.
- Pressure sustaining valve (if applicable) adequacy.
