Have you tried Fairbanks Morse?

What is the pump discharge pressure?

 

[Valving]

Total dynamic head is 120 meters, I guess you ask for this.
I will check them

what you need is a vertical line shaft pump driven by a diesel engine through a right angle gear box.
Just google vertical fire pump and you will find more than you can handle. Big time players such as Peerless Pump( Grundfos now), ITT / Gould, SPP.

One issue is that a single stage mixed flow pump may not be able to produce 120 meters of head. Because of the typical discharge pressure available from mixed flow pumps, mixed flow pumps are not generally used for fire service. Because of that, it may be difficult to find a UL/FM approved mixed flow pump.

You probably will need to look into use of a vertical turbine pump:

You can get UL/FM approved vertical turbine pump that meet your discharge and pressure requirements.
