Dear Customer,

We recently added a constant temperature and humidity test chamber to our quality control lab. This allows us to test your water pumps under extreme conditions from -40°C to +150°C and 20% to 98% relative humidity – including thermal cycling, damp heat, and low-temperature startup.

All water pumps now benefit from stricter environmental validation before shipment. Test reports are available upon request.

Thank you for your continued partnership.

Sincerely,

Xiamen Moonseek Industry Co., Ltd
