Description
Product Overview
The Lister Petter LP Series water-pump engines are purpose-built, liquid-cooled diesel engines optimized for industrial, municipal, and agricultural pumping applications. Designed for high durability and long maintenance intervals, they support fixed-speed operation (1,500–3,000 rpm) and deliver continuous power in the range of 6.8 to 34.0 kW (9.1–45.6 bhp). They are rated for reliable continuous duty in ambient temperatures up to 52 °C and can cold-start in environments as low as −32 °C.
Key Features
- Robust Cooling System: Thermostatically controlled, belt-driven water pump with radiator and fan (guarded).
- Long Service Interval: Oil and filter change interval up to 500 hours, depending on conditions.
- Fixed-Speed Operation: Available in 1,500; 1,800; 3,000; and 3,600 rpm variants, ensuring stable pump performance
- Cold-Start Capability: Designed to start reliably down to −32 °C (−25.6 °F).
- Fuel System: Self-venting fuel system with individual injection pumps, fuel lift pump, and agglomerator filter for clean, reliable fueling.
- Durable Construction: Heavy-duty air cleaner, SAE-5 flywheel housing, and ring-gear flywheel standard.
- Starter & Charging: 12 V electric start with alternator; 24 V optional.
- Cold Climate Enhancements: Inlet manifold heater plugs and safety switches included.
Applications
- Municipal water supply and irrigation pumping stations
- Agricultural irrigation systems
- Industrial pump drives for high-pressure or high-volume systems
- Remote or unattended pumping installations with long service intervals
