    Any suggustions for 2.5 inch nozzles for an industrial complex? Right now we are running straight off the hydrant with a hydrant pressure of about 95 psi. This will change soon with the addition a primary and secondary fire pump which should charge the loop to around 140 psi. We have experience with TFTs and Akron and use Akron with our 1 3/4 attack lines. Looking for a recommendation for a 2 1/2 fog nozzle with a playpipe. Also any recommendations for a smoothbore would be appreciated as well but primarily interested in fogs.
    I'm very impressed with Akron ZeroTorque for 2-1/2" big benefit in controlling with high nozzle reaction. Particularily if only one FF. Going to have pretty high nozzle reaction at 140psi.

    Or in this application do you use a hydrant valve at hydrant gated down? Similar to a highrise/standpipe application? Reduce flow/pressure? Have neither in my area.

      No attempt to hijack this thread, but.....
      I've been a big fan of the Elkhart line for many years now, but lately I've noticed that once our nozzles get just a little age on them, they will not shut off completely. We primarily use SM-20s, some are fog only, some are breakapart with 15/16" smoothbores. Some are 100 psi and some are the low pressure nozzles. This is happening way to much for me to think that it's just our nozzles. This happens so much to us that the crews don't send them in for repair, it's become normal.

      Anyone dealing with this, and got any ideas how what may be the cause?

      Back to original thread: Elkhart Chief, 250 gpm @ 50psi with integral 1 1/4" smoothbore would be my choice. If you want a little more from the fog tip, go with an SM-30 low pressure that can get you up to 325 gpm. Bet you will find the need to gate the pressure down when the new pumps come online unless you're using a long hose lay.

        i think thats the one i was training with last night?(elkheart chief) the end came off and shot a heck of a smooth bore stream that dumped a LOT of water at 75psi, and with the end on it had a fog with well defined fingers a amazinvg coverage.. but the cost for a vfd is pretty high but worth it. im no expert, but i was impressed..
