Description:

The EPH series is a full-range high-pressure electronic coolant pump product line developed for hydrogen fuel cell systems, with power covering 900W to 4500W and adapting to 60kW to 200kW fuel cell systems. This series is a core component of the fuel cell cooling circuit; by precisely controlling the coolant circulation flow it keeps the stack working temperature stably within the optimal range, guaranteeing efficient and stable operation of the fuel cell system.

The whole EPH series uses a canned leak-free structure: the motor rotor is directly immersed in the coolant and drives the impeller to rotate through the magnetic field, completely eliminating the shaft seal structure of traditional mechanical pumps. This design fundamentally eliminates the risk of coolant leakage and needs no coolant refill maintenance. At the same time the internal flow channel of the pump body is precisely hydraulically optimized, achieving excellent hydraulic performance at each rated power - from 165L/min@15.2m for the EPH900 to 600L/min@24m for the EPH4500.

In terms of electrical safety, the EPH series realizes a dielectric insulation design, effectively solving the industry problem of insulation degradation caused by coolant ion precipitation in fuel cell systems. The product supports CAN 2.0B bus communication, enabling real-time data exchange with the fuel cell system BOP controller, and supports remote monitoring and intelligent speed regulation. The application of the permanent magnet synchronous motor ensures high-efficiency operation over the full working range.

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: What power fuel cell systems does each EPH model adapt to?
A: EPH900L-00 adapts to 60kW~80kW systems; EPH1500H-00 to 80kW~130kW systems; EPH2500H-00 to 120kW~200kW systems; EPH4500H-00 to 150kW~200kW systems. Higher power levels such as 5500W liquid-cooling pumps are also available.

Q5: What is the difference between the EPH series and an ordinary electronic water pump?
A: The EPH series is designed for the high-voltage safety requirements of fuel cell systems: first, it uses a canned leak-free structure, completely eliminating the mechanical shaft seal; second, it realizes dielectric insulation, solving the ion precipitation problem; third, it supports CAN 2.0B bus communication; fourth, it adapts to a high-voltage (250~750V DC) wide-temperature operating environment.

Q6: What is the protection class of the product?
A: The EPH series protection class reaches IP67, fully preventing dust ingress and withstanding short-term immersion in 1m of water.

Q7: 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.
