![]() ![]() What’s the Difference between Normal Motors, Inverter Duty Motors, and Explosion-Proof Motors? More about motors: What are the considerations for motor selection? Depending on the application and working environment, the type and specification of the motor are also different. When using it with a motor, you need to pay attention to whether there will be failures such as motor burnout. Generally speaking, most pumps need to be connected with a motor and a power as the source of power for the pump (except for specific types of pumps, such as air-operated diaphragm pumps, etc.). To get more information of flange, please refer to the following three articles about flange.Īrticle1: What is a Flange? What are the types of flanges?Īrticle2: 5 Types Commonly Used Flange FacesĪrticle3: Flange Standards (ANSI, JIS, DIN, GB) Different types of chemical pumps are also equipped with flange types of different specifications. ![]() In the application of medium and large pumps, the flange form is often used as the main connection method. Regarding how to connect and fix the pump and the pipeline, flanges, unions or hoses are usually used. The density of the transported liquid, the diameter of the impeller and the number of stages of the impeller will all affect the height of the head. The height to which the fluid needs to be moved, which means the vertical height from the fluid source surface to the final outlet, in m. Therefore, it is necessary to consider whether to use a chemical pump with good pressure resistance to meet the operating range of the system. If the range of working pressure is too high or too low, the expected delivery effect cannot be achieved. Working pressure is the force required to move fluid through the system. The amount of flow will affect the size of the pump and the diameter of the piping. It is usually denoted by the letter Q, the unit of measurement is: LPM, m³/h or m³/s. The capacity refers to the volume of fluid that the pump needs to deliver per unit time, and indicates the flow rate and amount of the fluid passing through the pump during delivery. What Is the Amount of Fluid Will Be Pumped? The fluid properties include corrosiveness, temperature, viscosity, concentration, specific gravity and impurities.įor the relevant technical terms of the pump, there is a detailed explanation in this article: What are the considerations when choosing a pump? It can be read to understand more about this.Ģ. Since the characteristics of chemical fluids will directly affect the type and material of chemical pumps used, understanding the characteristics of chemical fluids is the most preliminary task for pump selection. There are mainly 10 things, which are items that manufacturers must confirm with customers first.įirst, must know what the chemical fluid to be transfered is. Probably this is the common experience of lots of people, and it may make people feel a little troublesome, but because chemical pumps are specially designed for the special needs of the chemical industry, most of the chemicals are dangerous, so compared with the water pumps, there are of course more factors to consider before deciding on an appropriate chemical pump. For example, when purchasing chemical pumps, you need to provide basic operating conditions such as head and capacity. ![]() Since the installation the customer has reported that the stray oil mist issue has been alleviated and their pumps in the unit have cooler bearing housings.Ī brochure for Isomag bearing seals for pumps can be found here.When you purchase a new fluid equipment, the manufacturer needs the user to provide a series of operating conditions. Low operating temperature – does not increase the operating temperature of the bearingsĮasy installation and removal – O-ring fit on the OD of the Isomag bearing isolator makes it easy to install and if necessary remove and reinstall. In addition to providing superior sealing and protection Isomag bearing isolators offer:Ī high level of MTBR – projected operating life of 100,000 hours at 12,000 sfm (60 mps) Isomag magnetic bearing isolators eliminate stray oil mist their liquid tight sealing faces. ![]() The refinery agreed that Isomag magnetic bearing seals are the perfect solution to their growing problem. ![]()
