China QL-12(DC) Drainage Pump for Engineering Installation - Reliable Suppliers and Factory Solutions
Product Introduction
The QL-12(DC) engineering installation-specific drainage pump is a drainage device designed for engineering sites and fixed installation scenarios, suitable for conditions with low head requirements and stable drainage volume. This product features a compact structure, easy installation, and multiple built-in practical functions, effectively handling small-scale drainage needs, and is particularly suitable for engineering applications such as air conditioning condensate drainage and drainage of small equipment.
Product Features
Built-in Heat Preservation
The pump body has a built-in insulation layer, which can effectively prevent freezing in low-temperature environments and ensure stable operation of the equipment in cold conditions.
Built-in Check Valve
The integrated check valve design prevents liquid backflow, avoids system backflow, improves drainage reliability, and protects equipment.
Multi-functional Water Spout
The water outlet interface is designed flexibly to accommodate various pipe diameters and connection methods, facilitating engineering installation and system integration.
Defined Working Conditions
Designed specifically for low head and low flow conditions, it is suitable for applications with a head of less than 1.3 meters and a discharge capacity of less than 120L/h, ensuring that the equipment operates efficiently and safely within the specified parameter range.
Instructions for use: Please strictly adhere to the operating conditions of head ≤ 1.3 meters and discharge capacity ≤ 120L/h. Using the equipment outside these limits may result in damage or performance degradation.
