what is the most suitable pump to pumping water to different levels of multi-storey building by use of only one pump, from water sump?

A big centrifugal one.

And if is in the 4th basement of a 40 story building, be careful when you turn on the water in the 3rd basement! - JHF

This will depend on how high the multi storey building is AND how much volume is required at any point of time. Are you pumping to a set of header tanks, or will this be the supply main for the building?

Two or three, no problem for a centrifugal and pressure system.

As a generic response, positive displacement pumps (provided rated to absolute head) could cope, but need protection if there will ever be a shut off condition as something will break. Pipe ratings would also need to be adequate for the developed pressures at the lower levels.

There are many "deep bore" pumps that can elevate water to significant head.

Ask a pump supplier. They provide answers like this for free and provide options of how to achieve the end outcome that best suits your needs.

It all depends on the height of the building. Under 100 feet, a centrifugal pump to a cistern on the top, with level switches to cause the pump to work intermittently would work well. The various floors run from a vertical piping system.

Hot water gets to be a problem on long runs. Many hotels have a hot circulating loop(insulated) so people do not need to wait. Some condos have water heaters on each unit to allow each condo local control.

On a 1000 foot high building, you need cisterns on different floors, say every 5-6 floors. This prevents 1000 feet of head being felt at the bottom floor, this gets to be complex. They all need to be fail-safe floor drained so that a leak in a water room has only one way out - through it's drain. The floors are sealed with a lip to control worst case flooding.

You could ask the people who maintain the CN Tower, in Toronto, Canada, as there's a restaurant on the top. I'd do it for you, only that might make you lazy, and we don't want that, do we?

What you ask can be very complex or very simple. Most homes can be multi story building, so is the Empire State building. What you ask can fit anywhere in between. You want us to advise you with out information. Good luck with that.

It depends on the head pressure required to provide the desired system water pressure and flow at the highest point of distribution in the building.

All system dynamics must be taken into considerations such as height/distance to highest distribution point, length of pipe installed to service all points of distribution, quantity, diameter size, and type of pipe fittings, valves, and measuring instruments, distance from sump to intake of pump, desired/required system pressure, and minimum quantity of flow required.

Keep in mind the maximum amount of water available to the pump intake limits the maximum flow allowed. (Cannot pump the water out faster than it is flowing in.)

If the installed height is significant and/or the system dynamics present high resistance to flow there may have to be booster pumps installed at specific intervals when using centrifugal type pumps. (In-line circulation type.)

It may be possible to use a multi-stage turbine type pump that will meet all of the application requirements.

You must first identify pump performance requirements and system limitations then select the appropriate pump for the application.

Most pump suppliers will assist customers in selecting the appropriate pump for the application when supplied with the correct information.

Many suppliers will provide technical service support at the site to evaluate the application and then recommend a specific pump.

You get a hand pump with a buncha stages, mount this onna roof, get a buncha guys to pull handle, an you tell alla people in the building, only one guy at a time can use the water, ring this bell when you want water.

The most suitable pump is the one that performs the needed requirements.

And let me add that it was best to use a pump that is suitable to pump to the highest floor at the highest rate necessary.

There is so much information missing that he may have well of asked if there's enough electricity in the wall socket to power a lamp?

That needs to be put in a safe place. I expect to see this quite often from now on.
