24V Food-Grade Brushless DC Hot-Water Pump With 7.5L/min Flow, 3.5m Head And 100 C Liquid-Temperature Capability
The TOPSFLO TL-B04 is a compact food-grade brushless DC centrifugal pump developed for under-counter boiling-water dispensers, under-sink instant hot-water systems, filtered drinking-water appliances, and beverage equipment. Rated at 24V, it provides a maximum flow rate of 7.5L/min and a maximum static lift of 3.5m while consuming approximately 10.8W. Its high-temperature hydraulic design supports pure-water temperatures up to 100 C, making it suitable for applications where near-boiling water must be transferred reliably within a compact appliance.
The pump combines high-temperature-resistant wetted materials, a brushless DC motor, continuous-duty capability, and an optimized high-temperature exhaust structure to help reduce cavitation and maintain stable flow at elevated water temperatures. TOPSFLO also supports customized intelligent control and flow regulation for applications requiring multiple dispensing temperatures. With food-contact materials and manufacturer-listed NSF, FDA, and WRAS compliance, the TL-B04 is designed for premium drinking-water and beverage systems where thermal stability, compact installation, and long operating life are important.

Under-counter Boiling Water Dispensers Industry Overview
With rising consumer demand and the increasing adoption of smart home technology, people are establishing greater standards for drinking water safety, taste quality, convenience, and overall user experience. Traditional solutions, such as electric kettles, countertop water purifiers, and conventional water heating systems, are increasingly unable to meet the demands of premium household applications due to limitations such as long heating times, inconsistent temperature control, and restricted space efficiency.
