Product Description
General description
The Goulds Model 3355 is a radially-split, segmented casing, multistage pump that is designed
with modular interstage components. This pump is manufactured in cast iron and 316 stainless
steel. This pump can be configured in two ways:
• Radial suction (RS) configuration
• End suction (ES) configuration
Radial suction configuration
This configuration features radial suction and discharge nozzles. You can position each nozzle
either vertically or horizontally at 90° to either side. This design consists of two robust bearing
housings with traditional bearings and mechanical seals on each end of the pump.
End suction configuration
This configuration features an end suction nozzle in conjunction with a radial discharge nozzle.
You can position the radial discharge nozzle either vertically or horizontally at 90° to either side.
The suction end of the pump utilizes a product-lubricated bearing that elminates the need for a
second bearing housing and mechanical seal.
Direction of rotation
The standard pump rotation is clockwise. As an option, the radial suction (RS) configuration
can be shaft-driven from the suction end in a counterclockwise rotation.
Intended applications
These pumps are well-suited for reverse osmosis and boiler feed applications.
