What is Grundfos Pump?

grundfos pump mainly provides water circulation in central heating system with radiator and floor heating system. You can also use a pump to circulate hot water in the house water supply system. In short, the circulating pump ensures that the hot water is delivered from the boiler to the radiator and even to the main water pipe. There are basically two types of pumps: the old three-speed/three-stage pump and the modern electric pump.

Frequently Asked Question

Do you have any question?

We already know that the electric circulating pump is undoubtedly of better quality and more economical. But how not to be overwhelmed by the expanded product range? Select according to the technical parameters of the heating building. If you want to purchase a pump for a new building, you will find the necessary data in the construction file. However, if you are looking for pumps for old buildings, you need to determine the parameters yourself.
To make a decision, you need to know the volume of heating system and water, the number of radiators or the area of floor heating. Therefore, select the required power, called the maximum head, and possibly the number of pumps. In order to install the pump correctly, you must also know the pitch and diameter of the connecting thread.

Circulating Pump Grundfos refers to the circulating liquid pump used for conveying reaction, absorption, separation and absorption liquid regeneration in the device. Its head is low and is only used to overcome the pressure drop of the circulating system. Low head pump can be used.

1. The circulating pump adopts excellent hydraulic model and advanced manufacturing technology, which greatly improves the performance and service life of the pump.
2. As the shaft seal is made of cemented carbide and fluororubber, it can improve the reliability of pump operation and the temperature of the transmission medium.
3. The overflow part of the pump is made of stainless steel plate by stamping and welding, which makes the pump suitable for slightly corrosive media.
4. The overall structure is compact, small in size, light in weight, low in noise, energy-saving *, and convenient in maintenance.
5. The water inlet and outlet of the pump are located on the same horizontal line of the pump base and can be directly used in the pipeline.
6. With standard motor, users can easily equip the motor according to their needs.
7. The intelligent protector can be equipped according to the user's needs to effectively protect the pump from dry running, phase loss and overload.

Principle and classification of grundfos-pump.

Pump is a machine used to inhale or deliver liquids or gases, which uses pressure differences to generate fluid motion energy. Pumps can be divided into two categories: volumetric pumps and dynamic pumps. Volumetric pump refers to a pump that achieves the transmission of liquid or gas by changing the volume of the working chamber. Dynamic pump refers to a pump that achieves delivery by accelerating a liquid or gas.

How to choose a grundfos-pump?

Choosing the right pump is an important engineering issue that needs to be considered based on factors such as the nature of the conveying liquid, flow, head, system layout, and economics.
