Rotary Pump Startups

<<Many pump startups

are the culmination of months if not years of work designing the process, machine or system, specifying components,
instrumentation, protective devices, and reviewing and qualifying suppliers. It is also the most vulnerable time for any
pump. This article describes cautions,
reviews and inspections that should be
conducted before startup to help insure
that all those many gremlins of pumping
systems are found out and eliminated in
time.>>

Testing and Maintenance of Fire Pumps

<<Fire pumps are perhaps the most critical single piece of fire
protection equipment installed at a site. Just like people, fire pumps come in all shapes and sizes. Fire pumps are needed at sites where public water supply pressure is too low for sprinkler effectiveness or where there is no public water supply at all. In the former case, a booster fire pump is installed to boost public water pressure to increase sprinkler effectiveness. In the latter case, a fire pump is connected to a private water supply (storage tank, reservoir, lake, river, or other) to create water pressure needed for sprinkler effectiveness and fire-fighting efforts. Most fire pumps are either diesel engine driven or electric motor driven; however, some of those manufactured before 1974 are gasoline engine powered or even steam engine driven (though this is very rare). Booster fire pumps are usually electric pumps, whereas diesel fire pumps are more common on private water supplies.>> Received on Thu Apr 08 18:02:00 2004
