The 7.5HP Pulser MIAC7.5 Diesel Engine is a heavy-duty mechanical power unit engineered for agricultural, irrigation, and construction operations across Kenya. Operating at a stable 1500RPM, this air-cooled diesel engine delivers consistent torque and dependable output for belt-driven equipment such as concrete mixers, water pumps, milling machines, and farm machinery.

Built with an 87.5mm bore and a plunger bearing type fuel injection system, the engine ensures improved combustion efficiency, stable fuel delivery, and long operational durability under continuous load conditions.

The air-cooled system eliminates the need for radiator dependency, making it suitable for rural environments and remote project sites. Every unit supplied by Macire undergoes inspection and verification to ensure performance reliability and compatibility with Kenyan field conditions.
