pump tested today

the new pumper passed it's 5 hour pump test today, I don't have the specs yet. but it was already at 1500gpm at 1700 rpm, which is still a little below that engine's peak HP and torque curves. It did blow a valve during the 250psi test though, it made quite the guyser in the pump compartment, and blew water out any hole it could find. Fix a few things here and there, then it gets striped and lettered Monday, and the chief will probably accept delivery Tuesday.

progress report 4.23.09

I installed the generator today, a Harrison 8kw hydraulic. I've also installed the cord reel at the rear. One of the engineers gave me an idea for a set of rollers on a hinged piece, so the cord doesn't drag if pulled sharply to one side of the truck. I'll have to look into it a bit more.

The Preliminary (in house) pump test is scheduled for April 30th

going together

It's going together very quickly, the engineering department did a great job of fitting everything in, and the body crew has been cutting, bending, and assembling over the last week.

in production

The new truck is in the shop! The past week has seen the interior stripped, the pump shift installed, the engineering finalized, and Tuesday the first parts came off the Laser.

It doesn't look like much yet, but next week should see a flurry of work as the body and pump gets assembled.

Due to some clearance issues, the decision was made to upgrade the large diameter discharges to electric valves, and a unique primer configuration that I'm betting will become a common sight on future trucks.

Pictures to come soon.

In the paintshop

New 1441's chassis came out of the paintshop wearing it's new coat of yellow quite well.. It came in red originally, a cancelled order from Alexis Fire Inc. We were very lucky to locate a 2007 chassis with a 2006 emissions engine, which means not having to deal with the trouble of the diesel particulate filter or the soot plugging up an EGR valve.

The engine is a C7 Cat rated at 330hp. With a 1500gpm pump and an 8k generator, theres only 19Hp left in reserve. It'll really be pushing the output limits to the max.
