A centrifugal pump is based on the mechanism of centrifugal force. It is defined as a rotodynamic pump that has a rotating impeller for raising the rate of the fluid. From its mechanism, it may seem that centrifugal pump is quite a complicated thing. However, in reality, this type of pup is considered as the most simplistic equipments. The primary purpose of this pump is turning mechanical energy of an engine into kinetic energy or velocity, which generates the pressure so that fluid can come out. In various industrial plants, centrifugal pumps are used. To obtain a durable and seamless pump, you need to find professional Centrifugal Pump Distributors.
Vijay Engineering and Mechanical Company (VEMC) is one of the leaders in the world of electromechanical devices. If you are looking for a high quality Centrifugal Pump in India, VEMC is the right destination for you. Here in this article, we shall make efforts to provide primary knowledge to the readers about the centrifugal pumps. This type of pump has two major components; one is the volute and the other one is an impeller. Volute is basically the inactive part, which changes kinetic energy into pressure. On the other hand, impeller is the active part, which keeps rotating. This part aids in changing of driver energy into kinetic energy.
How It Uses Centrifugal Force?
Centrifugal force is defined as the force that is generated from a rotating substance. In centrifugal pump, this force is generated when liquid enters the pump suction and the eye of the impeller. Switching on pump or sending electrical energy to the pump will help the impeller to revolve. When the impeller starts revolving, it creates pressure on the liquid so that it can go outside or gain velocity. The liquid goes out from the eye of the impeller, and centrifugal acceleration helps it to gain force on its way. This type of pump works seamlessly for water pumping. To get high quality and durable pump, you need to find reliable as well as professional Centrifugal Pump Distributors.

Multistage Centrifugal Pumps
Multistage centrifugal pump is basically a variation of the centrifugal pump. It is like other centrifugal pumps, but with some mechanical changes. In multistage centrifugal pump, the most notable part is the presence of two or more impellers. These impellers can be installed on identical shafts or inside one common shaft. Shaft size may also differ in some case, as per the requirement of the mechanical works from the pump. Naturally, from the design of multistage centrifugal pump, it is inevitable that this kind of pump is used for releasing high quantity of water. Apart from multistage centrifugal pumps, you can also find two-stage and one stage centrifugal pump in India.
To buy centrifugal pumps, you can trust on the products of Vijay Engineering and Mechanical Company (VEMC). The company is a veteran in the field of electromechanical devices. It possesses ISO certification, which stands for trust and quality. Not just products, the company also offer excellent services to the customers too. Hence, choose centrifugal pump products from Vijay Engineering and Mechanical Company (VEMC).

Selecting the right pump for industrial purpose requires the buyers to focus on some important factors along with making a deep research on the kinds of pump available. Choosing the right pump for right job extends the durability of the pumps with making the whole process cost effective and more efficient which are the most important factors in industrial applications. Hence we have pumps like Kirloskar submersible pumps,Split casing centrifugal pumps, Multistage centrifugal pump, Vertical multistage pumps, etc. for better functioning at your industrial plants & sites.

Few of the important factors that can’t be overlooked while purchasing a pump are explained to guide the buyers.

1. Liquid properties:

The first and foremost point to consider is the type of liquid for which the pump is intended. The liquid has a big role to play in the pump selection process. All the properties of the liquid such as temperature, specific gravity, viscosity, vapor pressure, PH value etc. is to be known before going ahead for the pump selection and buying decision. Doing so helps in selecting the best combination of pump suitable for that specific application or liquid.

2. Operating condition:

The selection of the right pump depends highly on the operating conditions or environment in which it has to work. While pump is to be installed then whether the pump will be running continuously for all the time or just as per the requirement needs to be analyzed while selecting a pump. Also the temperature, altitude, atmospheric pressure and location of the pump are also important factors to be looked at while selection.

3. Efficiency rating:

Efficiency rating is a key point to consider when it comes to choose the appropriate pump for a specified job. Pump consumes huge amount of energy than anything else. So, it is advised to select the best energy efficient pump as it saves huge money on the bill. The pump should be selected in the zone of 50% left of BEP(Best Efficiency Point) and 120% to the right of the BEP point on the curve.

4. Net Positive suction head:

NPSH can be defined as two parts: NPSH Available (NPSHA): The absolute pressure at the suction port of the pump and NPSH Required (NPSHR): The minimum pressure required at the suction port of the pump to keep the pump from cavitating.

NPSHA is a function of your system and must be calculated, whereas NPSHR is a function of the pump and must be provided by the pump manufacturer. NPSHA must be greater than NPSHR for the pump system to operate without cavitating. Put another way, you must have more suction side pressure available than the pump requires.

5. Power Rating:

The pump is driven by the prime mover i.e Motor or Engine .The power required to pump liquid from one place to other is very important and needs to be checked very carefully as it will affect the overall operating cost of the system .It is very crucial to check whether the power rating for the pump is at the optimum level to handle the load and not create any problem in future.
