Large vertical pump installation

[JohnWeal]

To install a large vertical 12,000 kg pump / motor on a concrete pedestal, what is a typical installation procedure from installing the rebar, casting the plinth, cure time levelling, screeding etc?

What are the key factors in a successful and vibration free installation?

The pump has a 700mm inlet and outlet, the inlet being vertical has a 90 degree duckfoot bend which is to be located beneath the two individual concrete plinths to keep the pump height as low as possible.

Pump info in this case: speed is 690 RPM and delivers 1571 litres / second at 19.4m head with a motor size of 500 kW.

Best Regards

John

Hi John

I gave you this guide to pump installation in the other pump base question you posted:-

There are a number of books and training seminars on this topic. Here is one:

WIth reference to the pump itself, the most important factor in installing a vertical pump is that it hangs absolutely vertical.

Apologies Desertfox, you certainly did...

Thanks for the replies I will check them out also.

The procedure you are asking is about the concrete foundation. it should be a civil engineer's domain.
As for the pump installation, from the drawing provided in your earlier thread, the pump is a large pump. You should follow the manufacturer's recommendation to avoid any argument in case of a warranty issue crops up later.
The basic things to look out for are leveling, pipe strain and coupling alignment.
