Pump Working pressure
Pump Working pressure
(OP)
Hello
I wanted to know what exactly the term Working pressure of Pump Means
What is casing working presuure of pump
How to calucalate the Working pressure in a closed loop chilled water pump system
we have a installation wherby the pumps are installed in the ground floor and pumping up to 35 floors
With each floor measuring 3.5 meters the total height of the building is 122.5 meters.
The return line back to the Pump suction is comming from 35th floor.
What working pressure of a pump should i select
please advice
regards
Najeeb

RE: Pump Working pressure
flange under any operating condition.
For your application you first have to know what total head you need and at what flow rate. The static head requirement is often the main component of total head, how high do you need to get the water based on the level of the suction tank? The next important consideration is how much friction do you need to allow for, this depends on the length of pipes and their diameter. The sum of the static head and friction head will give you the total head. The total head and your flow requirement will allow you to buy the right pump.

RE: Pump Working pressure
1. what pressure the pump casing must withstand so that it won't fail?
or are you asking
2.what head the pump must be able to develop to maintain flow?
It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

RE: Pump Working pressure
As far as for static pressure on the pump casing that is a different story. At a total building height of 122.5m this is equivalent to 174 psi static pressure. The pump casing (and piping) must be able to withstand this pressure.
