Pump selection calculation pdf

PUMP SELECTION DATA This table lists the important information on the pump that was selected to meet the process requirements. 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. Examples of common residential water systems 15.


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. For an existing pump , the diameter of the impeller is known.

Back to Basics W hen I left university, I found that I needed addi-tional information to turn my theoretical knowl-edge of fluid mechanics into the practical knowl-edge required to specify a pump. SUBMERSIBLES A GORMAN-RUPP COMPANY SUBMERSIBLE PUMP SELECTION (CONT.) CABLE SELECTION Select a drop cable designed for use in water. If two pumps are ideally at the intersection point, both pumps can be used.


Pump Sizing and Selection. You are told to purchase a pump for your manufacturing facility that will carry water to the top of a tower at your facility. The first step on the way to the optimal pump is the selection between a centrifugal pump or a positive displacement pump.


The difference lies on one hand in the prin-ciple of transpor-ting the liquid and on the other hand in the pumping characteristic. There are two types of centrifugal pumps : non-self priming and selfpriming.

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: Okay, you’ll have to pull the pump. Go ahead and hire someone with a well service rig. Well professionals have the right kind of equipment to pull a submersible pump without damaging the drop pipe, power cable and pump itself.


Think pump selection is an complex exercise? The following is a pump sizing problem to illustrate the calculations in this article. Use our Friction Loss Calculator to calculate.


Discover our easy-to-use pump sizing calculator – and ensure you make the right choice. Finding a pump to fit your duty points and application can be time consuming. But Grundfos Product Center helps you find the information you need fast – from application through to installation. The accurate calculation of the maximum and minimum total head is critical for the selection of a suitable pump.


Selection of an unsuitable pump can result in too much or too little water being pumped. The functions and types of pump are explained in detail under the General Design Guideline section. The theory section covers the selection method of the pump based on their application and engineering calculations for the sizing of the pump. These calculations are only a guide to assist selecting commercially available multispeed gear boxes. Renowned innovative hydraulic design.


Chapter 3: Review of Basic Vacuum Calculations Before we go any further, some time should be spent on some of the vocabulary specific to vacuum technology.

Vacuufrom a practical sense, vacuum may be defined as the condition of a gas under less than atmospheric pressure. This calculator allows you to figure out the head loss for pump selection. All you do is enter your specifications and click the update button to calulate total losses for the system.


Then select a pump based on flowrate and total head loss requirements.
