CLARKE ENGINES

Since 1964, Clarke has been assembling engines for fire pump systems. By working with the world’s leading engine manufacturers, all Clarke engines are guaranteed to deliver the most reliable and powerful protection for fire protection systems. With an engineering team dedicated to developing specialized components every day, Clarke provides a product truly designed for your installation.

  • Compliance with international standards such as NFPA 20, UL, and FM, ensuring quality and safety in every engine.
  • Extensive support network and readily available spare parts to ensure operational continuity and immediate response.

ANNUAL AND 2-YEAR MAINTENANCE

Regular maintenance is critical to achieving optimal engine performance. With service simplicity in mind, Clarke maintenance kits are designed and assembled in accordance with NFPA 25 recommendations (Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems).

Clarke maintenance kits are scheduled on a two-year replacement cycle. In the first year, Clarke annual maintenance kits include an oil filter, fuel filter, air filter, and zinc anode, all of which must be replaced regularly. In the second year, the Clarke Supplemental Maintenance Kit includes replacement parts for coolant-related items and common wear components, such as belts, heat exchanger hoses, pre-heater hoses, and gaskets that may crack due to continuous use.

Due to variations in engine bills of materials, confirmation of the engine serial number is required when ordering the second supplemental maintenance kit. Please contact us to identify the appropriate kit for your engine, and we will be happy to assist you.
