Which booster pump is typically used in distribution systems?

• A. Centrifugal Pump
• B. Reciprocating Pump
• C. Vertical Turbine Pump
• D. Diaphragm Pump

Answer: (C)

Boosting pressure in distribution systems hinges on delivering water against the system’s head, often from a deep source or up to higher elevations. A vertical turbine pump fits this role well because it is designed to develop high head with multiple stages and can be installed down in a well or vault, keeping the pump compact while delivering large flows to the distribution network. The motor is typically mounted above ground, while the pumping stages extend vertically, making it practical for boosting where space is limited and high pressure is needed.

In real-world booster stations, this arrangement handles the needed head efficiently, especially when drawing water from a deep source or when elevated storage requires substantial pressure increases. Other pump types aren’t as well suited for these conditions: centrifugal pumps are common for general boosting but may be less practical for deep lift or very high head; reciprocating pumps can provide high pressure but are more complex and maintenance-intensive; diaphragm pumps are limited to low-flow, low-pressure scenarios and not used for routine distribution boosting.
