Smart Dual-Use Cold and Hot Water Self-Priming Pump

The intelligent hot and cold dual-purpose self-priming pump is a modern water supply device that integrates automatic self-priming, intelligent start-stop control, and hot and cold water compatibility. Building upon traditional self-priming pumps, it incorporates pressure sensing technology and a high-temperature resistant structural design, achieving a truly "ready-to-use, hot and cold water compatible" intelligent water supply solution. It is primarily used to address problems such as insufficient water pressure, slow hot water supply, and frequent manual operation in homes and small commercial premises, serving as an upgraded replacement for ordinary self-priming pumps and traditional booster pumps.

Core Functions and Working Principles
1. Automatic Self-Priming System

The pump body features a gas-liquid separation and recirculation structure, enabling automatic self-priming after initial water filling. Even if the inlet pipe is full of air, the pump can quickly expel the air and draw water after starting. The self-priming height typically reaches 7–9 meters, suitable for installation conditions such as underground water tanks and low-level water sources.

2. Intelligent Pressure Control

A built-in high-sensitivity pressure sensor and intelligent control module continuously monitor pipeline pressure changes:

Water usage starts → Pipeline pressure drops → Water pump automatically starts

Water usage stops → Pressure recovers → Water pump automatically stops

The system also integrates dry-running protection, overload protection, and overheating protection to prevent dry burning and motor damage, enabling truly unattended operation.

3. Hot and Cold Water Dual-Use Design

The pump body is made of high-temperature resistant engineering plastic, cast iron, or stainless steel, and key sealing components use high-temperature resistant mechanical seals, allowing for stable delivery of both hot and cold water.
The medium temperature range is typically -20℃ to 90℃ (some models may have a higher range), making it directly applicable to water heaters, solar hot water systems, and underfloor heating systems.

Selection and Usage Recommendations

Choose the appropriate pump body material based on water quality and operating environment

It is recommended to use a small pressure tank to reduce frequent starts and stops and extend the pump's lifespan

In low-temperature areas during winter, take precautions against freezing; drain the water from the pump when not in use.
