🔍 Key Concepts

• High-head vs low-head pumps – which pumps are meant to produce high pressure vs high volume at low pressure • How the discharge piping from each pump is arranged in the SP-SW-01 drawing (length of run, number of coolers/valves it must push through) • Typical roles of main sea water circulating pumps versus sea water service pumps in a steam plant

💭 Think About

• Trace the discharge line from each type of pump on the drawing: which one feeds the most distant/complex header and multiple coolers, and which ones discharge almost directly to a condenser? • Ask yourself: which pump must overcome the greatest system resistance (elevation, long runs, many coolers and valves) to deliver adequate flow? • Consider normal plant design: which pumps are described in textbooks as high volume/low pressure and which as lower volume/higher pressure in sea water systems?

✅ Before You Answer

• Verify which pumps discharge directly to a nearby main condenser with relatively large piping and few restrictions – these are usually not high-head. • Verify which pumps supply a sea water service header feeding many different coolers and systems throughout the plant – these usually require the highest discharge pressure. • Double-check the labels next to each pump symbol on SP-SW-01 (single-speed main circ, two-speed main circ, aux circ, sea water service) and confirm which group is used for general service, not just condenser cooling.

Referring to the illustrated steam plant sea water cooling system drawing, which pump is considered a high-head pump operating with the highest discharge pressure? Illustration SP-SW-01

The two-speed main sea water circulating pump is considered a high-head pump.

The auxiliary sea water circulating pump is considered a high-head pump.

The single-speed main sea water circulating pump is considered a high-head pump.

Any of the sea water service pumps are considered high-head pumps.
