Eta Centrifugal Pump Catalog

Centrifugal Pump Catalog The centrifugal pump catalog is provided by the manufacturer and includes pump specifications such as pump dimensions, material of construction, performance curves and tables, and other pump details. The ETA series centrifugal pump is of the centrifugal type and is produced only in various sizes from 32 mm to 300. The body and impeller of these pumps are made of cast iron, and they can also be supplied with other materials if the customer requires. Eta pumps are capable of transferring large volumes of liquid. These pumps are mainly used in industrial, production, and process units. Depending on size, they are coupled with motors at 1450 rpm and 2900 rpm. The rotating system of these pumps is of the ball bearing type, which is lubricated with oil. Applications of the ETA Series Centrifugal Pump Suitable for providing pressure in water supply lines Firefighting systems Industrial applications Irrigation applications Agricultural applications Air conditioning systems Given the favorable performance and flow rate of the centrifugal pump, it can be said to be one of the most widely used pumps in various industries. One of the unique features of this pump model is that it always supplies a specific amount of water flow at a specific and constant pressure, and it increases the volume and pressure of the required water consumption. Also, due to their wide range of applications, these pumps are designed and manufactured in various types and are used in different fields. Thanks to the favorable application of this pump model, it can be used for moving liquids and fluids in domestic, industrial, and agricultural fields. Selecting the Required Pump for the Project Next, we want to select the ETA centrifugal pump whose flow rate and head are 50 cubic meters per hour and 29 meters, respectively. 1) Pump selection: First, by referring to the overlap curve of centrifugal pumps, we will have two options with these specifications: a. Pump 65-315 at 1450 rpm b. Pump 50-160 at 2900 rpm According to physical laws, we find that pumps at high speeds experience more severe wear than operation at low speeds, and if the pump operates continuously, we must definitely use pump (a) (65-315). 2) Determining the impeller diameter: We refer to the hydraulic performance curve of the 65-315 centrifugal pump at 1450 rpm. On the curve, we find the intersection point of the flow rate of 50 cubic meters per hour and the head of 29 meters, and the first curve above this point, which corresponds to the impeller with a trim of 310, is
