This three-part series focuses on the pump selection process.

Part 1 - Pump System Basics
Whether for a new pump application or for a pump replacement, it is important to understand the full range of expected operating conditions, and the system parameters dictated by those conditions. The machine mounting method, its vertical location relative to the liquid level, and environmental conditions must also be considered. This presentation addresses those concerns and introduces the process of properly selecting a pump for a particular application.

Part 2 - Pump System Concerns
When requesting a proposal for a new or replacement pump, a customer may provide you with specific pumping parameters, such as required head, flow and NPSH – or not. It is helpful when specifying a pump, to understand the system parameters that determine those required pumping parameters. This presentation will go over the basics of determining system parameters for pump applications.

Part 3 - Series and Parallel Pumps
There are many guidelines for designing multiple pumps for a single system. The most basic concern is to understand the requirements when multiple pumps are arranged in series and/or in parallel. Also, the design of systems has been become more flexible with the availability of variable speed drives, which are often applied in multiple pump installations. This presentation addresses those concerns and sheds some light on issues that result from misapplication.
