New Energy Power truck parts water pump P900724L18-P8 1307010-KZ9H0

Built to ensure stable coolant flow for new energy truck heat management, both pumps deliver industry-leading efficiency. P900724L18-P8 uses a centrifugal impeller with 12 curved blades, achieving a maximum flow rate of 80L/min and pressure head of 5.2bar—sufficient to cool 120kW hydrogen fuel-cell stacks, maintaining optimal operating temperatures (60-80℃). 1307010-KZ9H0 adopts a mixed-flow impeller design, delivering 55L/min flow and 3.8bar pressure, ideal for cooling 800V inverters (preventing overheating above 120℃). Both feature brushless DC motors (P900724L18-P8: 48V; 1307010-KZ9H0: 24V) with ≥92% energy efficiency, reducing battery power consumption by 15% compared to brushed pumps—extending EV driving range by 5-8% in urban conditions

Engineered for the harsh operating conditions of commercial new energy trucks, both pumps integrate robust structural and sealing systems. P900724L18-P8 uses a dual-mechanical seal (silicon carbide vs. carbon) with a stainless steel (316L) housing, resisting corrosion from hydrogen fuel-cell coolants and withstanding temperatures up to 150℃. 1307010-KZ9H0 features a single mechanical seal (tungsten carbide) and aluminum alloy (ADC12) housing, optimized for lightweight (1.8kg) and resistance to inverter dielectric fluids. Both have reinforced impeller shafts (P900724L18-P8: chrome-plated steel; 1307010-KZ9H0: stainless steel 430) with wear resistance, ensuring a service life of over 10,000 operating hours—equivalent to 5 years of heavy-duty use

Designed with comprehensive safety features to protect new energy cooling systems, both pumps include multi-layer safeguards. P900724L18-P8 integrates over-temperature protection (160℃ cutoff) and over-current protection (15A limit) to prevent motor burnout, critical for fuel-cell stack safety. 1307010-KZ9H0 adds dry-run protection (triggered after 30s of no coolant flow) and voltage fluctuation resistance (18-32V for 24V models), avoiding damage in inverter cooling loops. Both have IP6K9K waterproof/dustproof ratings, ensuring reliability in heavy rain or dusty construction sites. Additionally, P900724L18-P8 includes a pressure sensor port for real-time flow monitoring, while 1307010-KZ9H0 has a temperature sensor to sync with the vehicle’s BMS—enhancing system safety and diagnosability

Optimized for efficient fleet maintenance, both pumps feature user-friendly designs that reduce replacement time. P900724L18-P8 uses a quick-connect flange with pre-installed O-rings (nitrile rubber) for leak-free assembly, requiring only a torque wrench (recommended 25-30N·m) for bolt fastening. 1307010-KZ9H0’s compact size (150mm×120mm×80mm) allows installation in tight inverter compartments, with a plug-and-play electrical connector (AMP Superseal 1.5) that eliminates wiring errors. Both pumps are maintenance-free—no oiling or seal replacement needed—and include clear labeling (part number, voltage, flow rate) for easy identification. A professional technician can replace either pump in 25 minutes or less, minimizing truck downtime—critical for commercial logistics operations. Their durable design also reduces long-term maintenance costs, aligning with new energy fleet efficiency goals
