Fire hose - Wikipedia
A fire hose (or firehose) is a high-pressure hose that carries water or other fire retardant (such as foam) to a fire to extinguish it. Outdoors, it attaches either to a fire engine, fire hydrant, or a portable fire pump. Indoors, it can permanently attach to a building''s standpipe or pluing system.. The usual working pressure of a firehose can vary between 8 and 20 bar (800 and 2,000 kPa

Can Pump Suction Presure Be Higher Than Discharge Pressure
11.03.2013· Other way to see this is from Head perspective. The differential head is Discharge head - suction head. So the discharge pressure has to be greater than the suction. Suction pressure diameter is usually 1 size higher than discharge, because we need minimum resistance in the suction side to reduce the losses and increase the NPSHa. Thanks.
THE COMPONENTS OF TOTAL HEAD
It is more useful to use the difference in pressure vs. the discharge pressure as a principal characteristic since this makes it independent of the pressure level at the pump suction and therefore independent of a particular system configuration. For this reason, the Total Head is used as the Y-axis coordinate on all pump performance curves (see Figure 4-3). The system equation for a typical s

Fire Pump Testing - Hose Valve Manifold vs Flow Meter
16.04.2014· Hose valve manifolds are fed from a dedied pipe originating from the fire pump discharge so that flow measurements from the fire pump can be measured while the sprinkler system is isolated. The specific, recommended procedure of testing a new fire pump installation is outlined in NFPA 20 (2013) Chapter 14. We will not go into the details regarding this testing procedure, but we will point
Practical Considerations in Pump Suction Arrangements
Check valves are installed on pump discharge lines to prevent liquid flow reversal with the succession of pumping. In a similar fashion, a foot valve is simply a form of check valve, usually in a vertical position, usually incorporating a strainer, installed in the pump suction line (see Figure 3). The purpose of the foot valve is to preclude back-flow from the pump through the suction line
