New Energy Power engine parts water pump P900724L52-P8 1307010-TE810

Built to deliver stable, high-flow coolant circulation for new energy engine heat dissipation, both pumps excel in efficiency and performance. P900724L52-P8 adopts an 18-blade centrifugal impeller (made of glass-fiber-reinforced PPS with 30% fiber content) that achieves a maximum flow rate of 120L/min and pressure head of 7.2bar—sufficient to maintain fuel-cell stack temperatures within the optimal 65-85℃ range, even under full-load long-haul operation (e.g., 40-ton FCEV trucks). 1307010-TE810 uses a mixed-flow impeller (aluminum alloy ADC12 with hard anodization) with 12 curved blades, delivering 70L/min flow and 4.5bar pressure, ideal for balancing cooling demands between EREV range extenders (preventing overheating above 110℃) and battery packs. Both are equipped with brushless DC motors (P900724L52-P8: 80V; 1307010-TE810: 24V) with energy efficiency ≥95%, reducing battery power consumption by 22% compared to traditional brushed pumps—extending FCEV/EREV driving range by 8-12% in highway scenarios

Engineered for the rigorous demands of commercial new energy engines, both pumps feature robust structural and sealing systems to ensure long-term reliability. P900724L52-P8 has a stainless steel (316L) housing that resists corrosion from hydrogen fuel-cell coolants (deionized water + advanced organic inhibitors) and withstands continuous temperatures up to 170℃; it uses a dual-mechanical seal (silicon carbide vs. tungsten carbide) with a heat-resistant fluoroelastomer bellows, achieving zero coolant leakage for over 15,000 operating hours. 1307010-TE810 adopts a lightweight aluminum alloy (ADC12) housing (with a ceramic coating for corrosion resistance) and a single mechanical seal (carbon vs. ceramic) optimized for EREV engine coolants (ethylene glycol + propylene glycol blends). Both have reinforced impeller shafts (P900724L52-P8: chrome-plated alloy steel with nitride treatment; 1307010-TE810: stainless steel 430) with high wear resistance, ensuring a service life of over 18,000 operating hours—equivalent to 8 years of heavy-duty use

Designed with comprehensive safety features to protect new energy engine cooling systems from faults, both pumps integrate multi-layer safeguards. P900724L52-P8 includes over-temperature protection (180℃ automatic shutdown), over-current protection (25A limit), under-voltage protection (60V cutoff), and reverse polarity protection—critical for preventing motor burnout in fuel-cell systems where coolant temperature and voltage fluctuations are frequent. 1307010-TE810 adds dry-run protection (triggered after 15 seconds of no coolant flow), voltage surge resistance (18-36V for 24V models), and short-circuit protection (instantaneous current limiting to ≤80A), avoiding damage during EREV mode transitions (electric to range extender). Both have an IP6K9K waterproof/dustproof rating, ensuring reliable operation in heavy rain, snow, or dusty construction environments. Additionally, P900724L52-P8 features a built-in pressure sensor that transmits real-time flow data to the engine control unit (ECU), while 1307010-TE810 has a temperature sensor for coolant condition monitoring—enhancing system diagnosability and proactive maintenance

Optimized for efficient maintenance in commercial fleet operations, both pumps feature user-friendly designs that reduce installation and upkeep time. P900724L52-P8 uses a quick-connect flange with pre-installed fluoroelastomer O-rings (resistant to high temperatures and coolants), requiring only a torque wrench (recommended 35-40N·m) for bolt fastening—no specialized tools needed. 1307010-TE810’s compact size (170mm×140mm×90mm) allows installation in tight engine compartments, and it has a plug-and-play electrical connector (Delphi Metri-Pack 280) that eliminates wiring errors (keyed design prevents reverse connection). Both pumps are fully maintenance-free—no oiling, seal replacement, or filter cleaning required—and include clear labeling (part number, voltage, flow rate, compatibility, and safety warnings) for easy identification. A professional technician can replace either pump in 32 minutes or less, minimizing engine downtime—critical for logistics and delivery operations. Their durable design also reduces long-term maintenance costs, aligning with new energy fleet efficiency and sustainability goals
