Dear Valued Customer:
Clarke Fire Protection Products is proud to announce the formal release of our new UL Listed and FM Approved C32H0 series fire pump engines. The C32H0 series engines have been developed using the renowned 32-liter Caterpillar® engine platform which is synonymous for its performance and reliability across a range of demanding applications worldwide.
Clarke’s decision to expand our Caterpillar® based offering is in response to customer demand for greater choice of engine selection for large capacity fire pump applications. The C32H0 series will be available in both standard constant speed format or with a variable speed (PLD) configuration.
