New Energy Power truck parts water pump P900724L32 1307010-TZ3A0

Built to deliver stable, high-flow coolant circulation for new energy truck heat dissipation, both pumps excel in efficiency and performance. P900724L32 adopts a 16-blade centrifugal impeller (glass-fiber-reinforced PPS material) that achieves a maximum flow rate of 105L/min and pressure head of 6.5bar—sufficient to maintain fuel-cell stack temperatures within the optimal 60-80℃ range, even under full-load long-haul operation. 1307010-TZ3A0 uses a mixed-flow impeller (aluminum alloy ADC12) with 11 curved blades, delivering 60L/min flow and 4.0bar pressure, ideal for cooling 800V inverters (preventing overheating above 125℃) and reducing power loss. Both are equipped with brushless DC motors (P900724L32: 60V; 1307010-TZ3A0: 24V) with energy efficiency ≥94%, reducing battery power consumption by 20% compared to traditional brushed pumps—extending EV/FCEV driving range by 7-10% in urban or highway scenarios

Engineered for the rigorous demands of commercial new energy trucks, both pumps feature robust structural and sealing systems to ensure long-term reliability. P900724L32 has a stainless steel (316L) housing that resists corrosion from hydrogen fuel-cell coolants (deionized water + organic inhibitors) and withstands continuous temperatures up to 165℃; it uses a dual-mechanical seal (silicon carbide vs. tungsten carbide) with a heat-resistant rubber bellows, achieving zero coolant leakage for over 14,000 operating hours. 1307010-TZ3A0 adopts a lightweight anodized aluminum alloy (ADC12) housing (corrosion-resistant) and a single mechanical seal (carbon vs. ceramic) optimized for EV inverter coolants (ethylene glycol-based). Both have reinforced impeller shafts (P900724L32: chrome-plated alloy steel; 1307010-TZ3A0: stainless steel 430) with high wear resistance, ensuring a service life of over 16,000 operating hours—equivalent to 7 years of heavy-duty use

Designed with comprehensive safety features to protect new energy cooling systems from faults, both pumps integrate multi-layer safeguards. P900724L32 includes over-temperature protection (175℃ automatic shutdown), over-current protection (22A limit), and under-voltage protection (48V cutoff)—critical for preventing motor burnout in fuel-cell systems where coolant temperature fluctuations are frequent. 1307010-TZ3A0 adds dry-run protection (triggered after 20 seconds of no coolant flow) and voltage surge resistance (19-35V for 24V models), avoiding damage during EV rapid charging or sudden load changes. Both have an IP6K9K waterproof/dustproof rating, ensuring reliable operation in heavy rain, snow, or dusty construction environments. Additionally, P900724L32 features a built-in pressure sensor that transmits real-time flow data to the vehicle’s BMS, while 1307010-TZ3A0 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. P900724L32 uses a quick-connect flange with pre-installed nitrile rubber O-rings, requiring only a torque wrench (recommended 32-37N·m) for bolt fastening—no specialized tools needed. 1307010-TZ3A0’s compact size (155mm×125mm×82mm) allows installation in tight engine compartments, and it has a plug-and-play electrical connector (AMP Superseal 2.0) that eliminates wiring errors. Both pumps are fully maintenance-free—no oiling, seal replacement, or filter cleaning required—and include clear labeling (part number, voltage, flow rate, and compatibility) for easy identification. A professional technician can replace either pump in 28 minutes or less, minimizing truck 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
