Pump selection procedure

The automated Excel spreadsheet assists in calculating the key parameters for pump sizing and selection. Since the majority of the pumps used in the chemical process industries (CPI) are centrifugal pumps , this article focuses on that equipment category, rather than the other general classes of pumps , such as rotary and positive displacement pumps. Guidelines for selection. Select the pump based on rated conditions as per the data sheet. Ideally the pump should have a suction specific speed of less than 1000.

Selection of the pumping equipment is a crucial point that determines both process parameters and in-use performance of the unit under development.

During selection of the type of pump three groups of criteria can be distinguished: 1) Process and design requirements. Nature of pumped medium. The following are general considerations only for the application of BSM pumps. It is recommended that unusual or difficult design and application problems be referred to BSM Pump Corp. The “H” refers to total head and the “Q” is the flow in gpm.

The pump curve permits the use of the system curve as a method of pump selection. Pumping head (often referred to as total head) is the sum of all pressure requirements necessary for proper system operation. The engineer in charge of pump selection must carefully consider the duration of operation at each duty point to select properly the number of pumps and the control system to use.

Think pump selection is an complex exercise? As the pump experts, we are here to make the process as pain-free as possible. SELECTION OF JET, JETINOX AND JETCOM PUMPS Hs max = m Assume we wish to supply water from a nearby well to a detached home composed of ground floor and first floor. The installer has informed us that the house has KITCHEN and BATHROOMS. The water level in the well with respect to the pump suction port is located at hs = m. The pump doesn’t know anything about hea head is a concept we use to make our life easier.

The pump produces pressure and the difference in pressure across the pump is the amount of pressure energy available to the system. Find the Right Pump for Your Needs. Pump selection Centrifugal pump selection process Centrifugal pumps can be used in many applications, but in order to operate reliably, with optimal energy use and maximum life span, a pump ’s design characteristics must suit the intended service. Barnes and Noble, and AuthorHouse.

Discover essential variables you should know when starting the pump selection process. This enables the pump to start dry and re-prime itself without manually adding water. In addition, these pumps can be used when lots of air has to be moved such as with well point dewatering systems. A water system needs to move the water produced from the source to its customers.
