Fire Pump Maintenance

Fire pumps and the electric motors or diesel engines that drive them are the heart of a facility’s sprinkler system. Fire pumps ensure ample water pressure and volume are delivered to the entire fire protection system. Whether your fire pump is driven by a diesel engine or an electric motor, LionHeart offers the expertise to keep your drive and drive control systems in peak operating condition.

Properly operating fire sprinkler systems can reduce the average property loss by 71% in the event of a fire, however improper fire pump maintenance can result in less effectiveness – or even failure – for the fire sprinkler system. LionHeart’s preventative maintenance practice for diesel fire pump engines closely follows our proven guidelines for maintenance of emergency generator engines. Our technicians perform a comprehensive fire pump inspection of the diesel engine as well as full maintenance to include replacement of engine oil, oil filters, and fuel filters. With approval, an operational churn test (no flow test) is performed to ensure proper engine and control operation. It is highly recommended that clients become familiar with all NFPA 25 (standard for the inspection, testing, and maintenance of water-based fire protection systems), requirements that may not be covered under their current maintenance or service agreements. These additional requirements are typically handled by the client due to frequent maintenance intervals (weekly, monthly and quarterly). These requirements include, but are not limited to:
  • Running the diesel fire pump engine for 30 minutes weekly.
  • Running the electric fire pump for 10 minutes monthly.
  • Testing the diesel fuel tank float switch(s) and interstitial space float or supervisory signals quarterly.
By meeting the requirements of NFPA 25 you will not only be assured your system meets all critical inspection and testing points, but you will also maximize the system’s reliability. LionHearts EGSA certified Field Service Engineers (FSEs) are mechanical, electrical, and diesel engine experts who are well-versed in the unique installation and operational aspects of diesel engine fire pumps. Note: LionHeart does not perform the annually required NFPA 25 flow tests, but we recommend our annual diesel engine maintenance service be performed in conjunction with the annual flow test. This coordination ensures a qualified mechanic is onsite and prepared to address any engine or engine control issue which may occur during the annual required flow test. LionHeart is well-versed in the repair, rebuild and complete replacement of fire pump engines. To ensure system readiness and reliability, LionHeart has developed extensive knowledge of NFPA 20 (Standard for the Installation of Stationary Pumps for Fire Protection.) Engine failures, long-term repairs and complete replacement projects require the use of portable, rental fire pump systems for which LionHeart can both supply and install.

Unmatched Expertise

We believe no organization should ever be at risk due to the failure of their critical power systems. LionHeart is the team you need for peace of mind.
