Water engineers and utilities are often faced with a decision concerning the best type of pump when designing a high-service pump station for delivery of potable water to the distribution system. For this application, the two most common types of pumps are horizontal split case (HSC) pumps and vertical turbine (VT) pumps.

The decision between horizontal and vertical is not trivial. There are strong supporters on each side who will indicate why one type of pump is better than the other, and in Florida, both types of pumps are common for high-service pumping. This article addresses the challenge of summarizing each pump type, listing key factors for making a comparison, explaining which pump type has the advantage for each factor, presenting a decision tree, and providing examples of applications through case studies.
