Kitchen Hot Water Dispenser & TOPSFLO High-Temperature Pump Solutions

A kitchen hot water dispenser, also known as an instant boiling/chilled water system or boiling tap, is a specialized appliance capable of heating drinking water to nearly boiling temperature within just two seconds. Such systems are widely applied in kitchens, bars, offices, leisure venues, clubs, and tea rooms, offering exceptional convenience for preparing tea, coffee, and other hot beverages. These appliances have long been prevalent in many overseas markets.

Despite their popularity, manufacturers of hot drink machines face significant technical hurdles. Since these devices must consistently maintain water temperatures between 98–100°C, product reliability and durability often fall short. Common issues encountered with conventional hot water pumps include:

• Deformation and aging of plastic housings under continuous high-temperature exposure, creating risks of leakage and safety hazards.

• Excessive noise developing after a period of use, leading to customer dissatisfaction and complaints.

• Unstable flow performance, where water output declines sharply or stops entirely when operating under boiling conditions.

• Short service life, with pumps requiring replacement after only a few months of operation.

TOPSFLO’s High-Temperature Pump Breakthrough

To address these long-standing pain points, TOPSFLO developed the B03, B04, and B10 series under-sink filtration systems pumps, specifically engineered for high-temperature hot drink machines. Since their market debut in 2014, these pumps have been successfully integrated into well-known hot beverage systems across Australia, the UK, the US, Taiwan, Japan, China, and other regions. End-users have reported consistently high levels of satisfaction over years of use.

Beyond low noise and reliable performance, TOPSFLO pumps offer unique advantages that have attracted numerous global brands.

Key Technical Advantages

1. High-Temperature Resistance

TOPSFLO pumps are designed to withstand extreme conditions, addressing the 98–100°C challenge at the material and structural levels:

• Use of Japanese-imported Xyron PPE engineering plastic, delivering superior thermal stability compared to conventional PA or domestic plastics.

• Injection-molded integrated magnetic rotor with imported magnets capable of tolerating up to 460°C.

• Premium-grade enameled copper wire rated for 180–220°C heat resistance.

2. Optimized Gas Exhaust & Flow Stability

Boiling water produces abundant bubbles, which can trap gas and obstruct flow. This often causes noise and reduced water output. Drawing on over 20 years of R&D expertise in micro-DC pumps, the TOPSFLO engineering team provides professional pipeline integration and design optimization. Solutions include:

• Enhanced inlet and outlet sealing.

• Proprietary exhaust design to accelerate gas release.

•  Tailored installation guidance ensuring best compatibility with customer applications.

3. International Safety Certification

TOPSFLO pump components have obtained FDA and WRAS certifications, ensuring compliance with the strictest global food and water safety standards:

• FDA (U.S.): Globally recognized for stringent requirements on food-contact materials.

• WRAS (UK): A mandatory drinking water safety certification for the UK market. Since no WRAS-authorized labs exist in China, all TOPSFLO materials were tested directly in the UK, undergoing year-long evaluation before approval. Regular follow-up inspections guarantee ongoing compliance. Very few Chinese pump manufacturers meet both FDA and WRAS standards—this distinction positions TOPSFLO as a preferred supplier to leading international clients.
