In a typical steam power plant, the boiler feedwater (BFW) pump takes suction from the deaerator (DA) and discharges high-pressure water to the boiler through the feedwater heaters. During normal ...

Fire pump accessories might not be glamorous, but priming systems are critical to pump drafting performance. Pulling a prime quickly is key to fast water delivery, a basic fireground necessity.

This diagram (which shows the low-pressure fuel circuit on the right side of the pump) is similar to what you’d see in a Bosch CP3.3 NH pump, which is the model used on an LBZ Duramax.

During a deaerator pressure transient, the actual pressure at pump suction decreases as the deaerator vapor pressure decays. However, due to hold-up of the hot-water slug in the pump suction line ...
