Pump Selection And Application Ppt This document discusses pump selection and applications. it begins by outlining the chapter, which covers introductory concepts in pump selection, parameters to consider, types of pumps including positive displacement and kinetic pumps, and performance data for centrifugal pumps. the affinity laws relating speed, impeller diameter, capacity. Thus, the details of the pump will start to emerge. 1. before talking about a pump, consider the pipe. velocity of liquid in pipes ranges between 3 to 10 feet per second (ft sec). if the velocity is too slow, the dirt, sludge or other contaminants can settle. if flow is too fast, abrasive wear will reduce the life of the pipe.
Pump Selection And Application Ppt Goulds pumps and rheinhütte pumpen presents this centrifugal pump selection guide to assist users in making an easy initial selection of the best pump for a particular service. to do this, simply refer to the selection chart on page 4 & 5 where the full line of goulds pumps, rheinhütte pumpen and pro services products are listed by. The three most common pump speeds in hvac applications: 2 pole, 3500 rpm. low flow rates, high head, intermittent operation. 4 pole, 1750 rpm. most common, low noise, long bearing and seal life. 6 pole, 1150 rpm. Presentation transcript. pump selection chapter 5. think of a sprinkler head, except you turn the sprinkler to move the water rather then the other way around centrifugal pump concept. principle of angular momentum conservation • momentum=mass*velocity • angular momentum=radius*mass*velocity • torque=time rate of change of angular momentum. 2. excellent engineering solutions weir minerals division 2 2.20 pump selection contents 2.21 pump selection logical approach 2.22 data storage for pump selection variables 2.23 effect of duty point on pump type & size 2.24 effect of slurry class on pump type 2.25 effect of process category on pump type 2.26 effect of wear on pump type & size power calculation 2.27 effect of total ownership.

Reducing the frequency (and rotational speed) from 60hz to 50 hz, or about 16.7% results in: a flow reduction of 16.7% to 1667 gpm. a head reduction of 30.6% to 69.4 feet. a power reduction of 42.1% to 38.8 hp. of course the pump will not necessarily run at this new flow and head. the actual new operating point depends on where the system head. November 7, 2023. selecting the right pump is a critical decision in various industries and applications. whether it’s moving water, chemicals, or other fluids, the choice of pump can significantly impact efficiency, safety, and overall operational success. in this comprehensive guide, we’ll delve into the intricacies of pump selection.
