    Default Hydrostatic fire pumps

    Who makes them? (hale, darley, waterous, etc.)
    What GPM Ranges?
    How come all we ever see is 500GPM?
    Pros?
    Cons?

    I know that Darley makes some, but their website stinks when it comes to information. What we want to do is build an interface engine capable of 750gpm for structure, but also have pump and roll capabilities. We are staying away from pto right now.

    You mean a hydraulic driven water pump? As in engine or transmission driven hydraulic pump suppling a hydraulic motor that powers the water pump?

    I think most pump manufacturers offer hydraulic drives on pumps that are 750 and higher. In most cases it is only a hydraulic motor mounting flange on the pump transmission. Pros are the ability to get higher pressures for pump and roll at lower speeds and you do not have to shift it like a split shaft pump. The cons are maintenance of the hydraulic system and cost.
