Circulating Pump

Circulating pump

The circulating pump refers to a circulating fluid pump that transports, absorbs, separates, and regenerates the liquid in the device. Its lower head is only used to overcome the pressure drop of the circulatory system. A low lift pump can be used. The circulation pump refers to the function of the pump, and the centrifugal pump refers to the structure of the pump. The two are completely two concepts. The working principle of the circulating pump is to circulate the water. The pump used is called a circulating pump. For example, the hot water in the plumbing heating pipe is circulated by the circulating pump.

Device characteristics

A pump for circulating fluids that transports, absorbs, separates, and regenerates the liquid in the device. A single stage centrifugal pump is generally used. The flow rate of the circulating pump is medium in size, and under steady operating conditions, the flow rate of the pump is relatively small. Its head is low and low, just to overcome the pressure drop of the circulatory system. A low lift pump can be used.

Heating circulation pump

advantage

No water leakage The magnetic drive has no moving seals, which fundamentally eliminates water leakage problems;

Low noise The accuracy of key parts is up to two thousandths of a millimeter to ensure quiet performance;

Long life. Mirror ceramic and ceramic nano-bearings are resistant to wear and ensure long life;

Less power consumption Because the matching is reasonable, the motor power is small, and the electricity cost per hour is about one cent;

Small size, light weight, long length × width × height = 120 × 76 × 105, less than one kilogram;

Low water quality requirements. If the circulating water contains small impurities, it will not affect the circulation pump work;

It has anti-burn function. If the pump is wrapped by debris, it will not damage the motor due to overload.

Precautions for use

1. Before installation, check whether the circulating pump inlet and outlet are blocked by foreign matter;

2. Flush the debris in the system piping before loading the system, so as to prevent the debris from winding around the impeller when the circulating pump is running;

3. The application force is soft during installation, please do not force it to avoid damaging the pump body;

4. The inlet and outlet of the circulation pump must be provided with a (live joint) for assembly and disassembly.

5. Safety wiring, the connection should be connected with the three-wire plug with ground wire, and the ground wire end is connected with the motor casing to ensure safety.

6. The product noise is low. When checking whether it is rotating, use a screwdriver to hold the ear to listen.

7. Enpu EP-XB500 pump diving part of the pump is lubricated with water, therefore, do not run for a long time without water.
