The Goulds Model 3393 is a radially split, segmented casing, multistage pump designed with modular
interstage components. These identical components can be assembled to produce pumps of varying
numbers of stages, hydraulics, materials, and configurations to meet the customer's specific require-
ments. Its multiple suction nozzle and discharge nozzle orientations allow the 3393 to adapt to multiple
piping installations and provide the piping designer with flexibility in plant layout. Multiple hydraulics for
each pump size optimize efficiency across a vast range of applications. All intermediate stage compo-
nents are identical which reduces spare parts inventory.
3.2 Pump description
Model 3393 Installation, Operation, and Maintenance Manual 17

The 3393 is designed as a two-pole speed pump. There will be times when the pump will be operated at
variable speed. The 3393 can be operated between 2700 and 3600 rpm without reference to the factory.
At speeds above 3600 rpm and below 2700 rpm, a lateral critical speed analysis must be conducted by
the factory. Contact your local representative for pricing. In all cases it is imperative that the pump be
brought up to its minimum operating speed as quickly as possible. This ramp up time should not exceed
5 seconds.
RS - Radial Suction configuration features radial suction
and discharge nozzles. The suction and discharge noz-
zles can be positioned either vertically or horizontally at
90O to either side. This design consists of two robust, fin-
ned bearing housings with traditional anti-friction bear-
ings and mechanical seals on each end of the pump.
ES - End Suction configuration features an end suction
nozzle in conjunction with a radial discharge nozzle. The
suction end of the pump utilizes a product-lubricated
bearing eliminating the need for a second bearing hous-
ing and mechanical seal. Because of the positioning of
the sleeve bearing in the end suction casing, the suction
flange size is one size larger than the size for the radial
suction arrangement. The discharge nozzle can be posi-
tioned either vertically or horizontally at 90O to either
side.
3.3 General description i-ALERT®2 Equipment Condition Monitor
Description
The i-ALERT®2 Equipment Condition Monitor is a compact, battery-operated monitoring device that con-
tinuously measures the vibration and temperature of the pump power end. The i-ALERT®2 sensor uses
blinking red LEDs and wireless notification to alert the pump operator when the pump exceeds vibration
and temperature limits. This allows the pump operator to make changes to the process or the pump be-
fore a catastrophic failure occurs. The Condition Monitor is also equipped with a single green LED to in-
dicate when it is operational and has sufficient battery life. (i-ALERT®2 Bluetooth Equipment Condition
Monitor option available. The i-ALERT®2 monitor allows customers to identify potential problems before
