Description:

In a fuel cell system, the stack continuously generates a large amount of heat during operation, which must be carried away in time through coolant circulation. The electronic water pump is the core component providing coolant circulation power in the thermal management system, and its performance directly affects the temperature stability of the stack and the system efficiency.

For small 5~30kW fuel cell systems (such as fuel cell forklifts and small commercial vehicles), using a 24V low-voltage electronic water pump has obvious advantages over a high-voltage water pump: the power supply system is simpler, the electrical safety is higher, and it is more conducive to the integration of the vehicle electrical system.

Compared with traditional brushed motors, the P800/P900 series brushless DC electronic water pump has the advantages of long life, high efficiency, low noise and low maintenance cost. Through the built-in electronic control unit, the pump can achieve precise flow control according to system requirements and has multiple smart protection functions. The product operating ambient temperature is -40~125C, medium temperature -40~120C, suitable for antifreeze and other cooling media. The product complies with ROHS environmental requirements.

P800 series (P800124F08): maximum flow 58+/-15% L/min, maximum head 12+/-1m, rated power 120W, weight only 0.98kg. This series has a compact structure and light weight, suitable for fuel cell systems with limited installation space. The product uses die-cast aluminum natural color + PPS black frame material, with inlet/outlet diameters adapting to standard cooling pipes.

P900 series (P900124F04): maximum flow 165+/-15% L/min, maximum head 11+/-1m, rated power 260W. This series is equipped with PWM speed control (frequency range 2~2000Hz, recommended 200Hz), able to dynamically adjust the flow according to the real-time temperature demand of the system. It also has a fault signal output function (open drain output), convenient for the system to monitor the pump operating state.

Smart protection functions:

Stall protection: when the rotor is stuck by foreign matter and cannot rotate, the pump automatically cuts off power and restarts after 5 seconds.

Dry-run protection: when the liquid in the pump changes from present to absent, it automatically slows down; after the liquid returns, it recovers within 5 seconds; after continuous dry-run for 120s+/-20s, it automatically stops and needs a power cycle to restart.

Power reverse connection protection: when the positive and negative poles are connected in reverse, the pump will not work and will not produce an irrecoverable fault.

Constant power output (P800 series): when the input voltage is from 26V to 30V, the pump working current adjusts automatically, with the maximum flow and maximum head basically unchanged.

Sleep mode (P900 series): when the PWM signal end detects a continuous low level exceeding 5 seconds, it enters sleep mode; when a high level exceeding 100us is detected, it wakes up.

FAQ

Q1: Can you provide samples for testing?
A: Yes, we support sample orders for vehicle installation testing and performance verification, and also accept mixed-model sample orders.

Q2: What is the delivery lead time?
A: Sample orders usually take 5-7 working days; bulk orders (depending on order quantity) generally take 15-30 working days.

Q3: Is there a minimum order quantity (MOQ) limit?
A: There is no strict MOQ limit; 3-piece sample trial orders are supported, and bulk order prices are more favorable.

Q4: Why choose a 24V electronic water pump for small fuel cell systems?
A: For small 5~30kW fuel cell systems (such as fuel cell forklifts and small commercial vehicles), using a 24V low-voltage electronic water pump has the advantages of a simpler power supply system, higher electrical safety and better vehicle electrical system integration.

Q5: What are the main differences between the P800 series and the P900 series?
A: The P800 series (P800124F08) has a maximum flow of 58L/min, head of 12m, power of 120W and weight of 0.98kg, suitable for small and medium power systems; the P900 series (P900124F04) has a maximum flow of 165L/min, power of 260W and weight of 1.88kg, equipped with PWM speed control and fault signal output, suitable for systems requiring a larger flow.

Q6: What smart protection functions does the electronic water pump have?
A: Stall protection (automatic power-off when stuck, restart after 5 seconds), dry-run protection (automatic slow-down when no liquid, stop after continuous dry-run of 120s), power reverse connection protection (does not work and is not damaged when reversed).

Q7: What are the installation requirements of the electronic water pump?
A: Horizontal installation of the inlet is recommended. Cover the dust cap when not in use for a long time to prevent dust from entering the inlet and outlet. Ensure there is some liquid in the pump before power-on; do not run for a long time without liquid in the pump.

Q8: How to handle product failures?
A: We implement a strict quality control system, with an out-of-factory defect rate below 0.2%. During the warranty period, small batches of defective products will be replaced with new ones in the next order; batch quality problems will be negotiated for repair or replacement to ensure customer rights.
