The horizontal split case pump has long been used for liquids handling where the utmost in reliability and accessibility is paramount. Billions of gallons of liquid have been pumped by their split case double suction pumps and billions more will be pumped, especially when you consider the rapid industrial, agricultural, and commercial expansion we’ve been seeing.

The Pentair-Aurora 410 Series pumps make a significant contribution to the customer requirements for axially split case pumps in this type of service. The 410 Series is a modern design based on Aurora’s 90+ years of experience with the design, sales and manufacturing of split case pumps.

Model 411 is horizontally baseplate mounted with a driver flexibly coupled to the pump. This design is recommended where floor space is readily available and where flooding of the installation is not possible.

Model 412 is vertically mounted and uses flexible shafting between the driver and the pump. This model is frequently used on difficult applications where flooding of the installation is a possibility.

Model 413 is vertically mounted with an elevated driver coupled directly to the pump through a flexible coupling. Model 413 is very popular for installations where available floor space is limited and where possible flooding is marginal.
