Can the CRN 90 1 Grundfos pump be adapted to the rectifier water circulation required 0 15 MP The ra

The material is different. The base of the CR is cast iron, the other overflow parts are 304 stainless steel, the base and other overflow parts of the CRI are all 304 stainless steel, and the base and other overflow parts of the CRN are all 316.

The difference between Grundfos Pump CR and CRN is the material. CR means that the pump base is cast iron, and the pump flow part is 316 stainless steel; CRN indicates that the pump base and overflow parts are made of 316 stainless steel.

Significance of other models: CRT means that the pump base and overflow parts are titanium alloy, and CRT indicates that the pump base and overflow parts are 304 stainless steel.

Grundfos is one of the world's leaders in the pump industry. Circulating pumps for heating and air conditioning, centrifugal pumps and metering pumps for industrial, water supply and wastewater treatment are its main products. Today, Grundfos is the world's largest manufacturer of circulating pumps, covering approximately 50% of the world's market.

If you want to say that the Grundfos pump is the most energy-saving, then choose the E pump, the so-called E pump is a water pump with a variable frequency motor, that is, the motor of the pump is integrated with an integrated inverter, which can be operated in open-loop or closed-loop mode, this pump should be the most energy-saving. At present, Grundfos' CR, CM, NBG, NKB, TP and other commonly used water pump series all provide inverter pumps with the suffix E series.

The CR SP TP small circulation pump has an energy label of Alpha 2

cr cm, etc.

Grundfos' products are very good, and they are 1-3 grades higher than domestic products!

It depends on where you use it, what medium, and what model you need.

The southern ones can, but you get the role is not big, the pump industry you get are all face prices, who will easily leak their bottom line, according to the needs of customers and the actual situation to get the discount of the goods must be different, I myself do pumps, as for Grundfos's **conventional pumps, that is, the common CR series small pumps on the market are the first and all are face prices and**very transparent**buy** are almost the same This **** Lanfu dealers have it Grundfos pumps with a power of more than 30kw There are pumps that are not marketable It will take time to ** without detailed project information It will not be out ** You just ask the salesman of the Grundfos factory and will not get it immediately because**He also does not know that it is possible that the same product will be very different in different projects** There is also that Grundfos pumps are mostly customized according to customer requirements Cutting impeller For example, the head is 120m and the flow rate is 10t, and the head flow rate of his pump is 120m 10t will not make much difference The efficiency is very high Energy saving Unlike domestic pumps, the difference is quite big, you may choose 130m 12t, if you want the price list very much, you can contact me, to be honest, you get the price list is not very useful.

This is a trade secret. If you need a pump of some kind or size, you can send them a letter.

I have used Southern Pumps, Wilo Pumps and Grundfos Pumps. Compared to this, the service life of Grundfos pumps and Wilo pumps is much better than that of Southern pumps. The lifespan is also long.

The first few are all domestic, low quality, and generally noisy.

The latter two former Germany and the latter Denmark, Wilo small pump (non-shielded) has a high market share and is widely used in solar energy and other industries, Grundfos large pump (centrifugal pump, etc.) has a high market share, and the shielded pump is almost the same, and the two are about the same, which is more expensive than the domestic one. Good quality, long life, low noise.

Now there are a lot of imitations of Wilo and Grundfos in the market, and when buying, carefully recognize and choose the larger ** merchants to buy. There are even real and fake mixed up.

Wilo pumps, Grundfos pumps imported brands, some products are imported originally, and the long-term stability is definitely better than that of domestic ones. The price is the same as that of imported cars.

Kaiquan water pump, Liancheng pump, South pump, Oriental pump, Carrier pump, Kaiquan should be recognized as better, in fact, the pumps are similar, the stainless steel multi-stage pump in the south is more famous, is to imitate Grundfos, **relatively high** and domestic cars are about the same.

Grundfos pump is a Danish brand, one of the world's leading pump enterprises, the quality is obvious to the world, in China also has its branches, in the Northeast, Shanghai, Suzhou, have its cooperative enterprises, the Northeast has Dalian Hairong fluid equipment, you can go, Dalian Hairong to see down.

Dalian Development Zone has ** Glenfos Will, Dalian Han Yuxuan Electromechanical **** 0411-87188347 Manager Xie.

First of all, we need to determine some basic parameters of the pump we need, and then list them. However, the focus should be on the flow rate of the pump and the head of the pump. The second is to consider the use environment of the pump, which is very important, especially the nature of the liquid to be transported by the pump.

Another is to consider the Grundfos pump, which is very important, related to our production costs, these are part of the rate we must testDalian Hairong Fluid Equipment****||There is a sale, you can go to consult!

According to the flow rate, head, power supply voltage during use, whether there are suction lift requirements, anti-corrosion (anti-rust) requirements of the water pump, whether the motor has anti-riot requirements, etc.

In fact, it is the same with any water pump. You need to know how long your water pipeline is and how big the drop is. Tell the pump seller that he knows how big you should buy.

As far as I know, the treatment is quite good, because the Grundford pumps are selling very well now, and the after-sales service is very good.

I heard that the treatment is the best in Suzhou!

Although Grundfos is a big brand, it has been many years since it entered China, and you are not a dealer in Shanghai, just a dealer below the dealer, to put it bluntly, it is just a part-time job, the sales advantage of a big brand is that the brand is big, the reputation is good, and the user is easy to accept, but the competition for conventional products is too big, and it will be difficult for a while if you just enter the industry. Of course, it's good if it's to accumulate experience, as a springboard, familiar with the industry and sales skills!

Although Grundfos has unique features in home and gardening, it is too transparent and has no good profits at all, so it is recommended to look for brands with moderate quality in Zhejiang.

As long as you work hard, you will have a future.

Serious efforts for good results.
