Goulds 3393 High Pressure, Multistage Ring Section Pumps

Product Description

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 requirements. 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 components are identical which reduces spare parts inventory. These pumps are particularly well suited for reverse osmosis and boiler feed applications. Shower services, booster service and other high pressure services are applications where the Model 3393 may be applied.

Specifications

  • Capacities to 3300 GPM (750 m3/hr)
  • Heads to 3300 feet (1000 m)
  • Temperatures to 400° F (204°C)
  • Pressures to 1650 psig (114 bar) 
Design Features

Precision cast impellers

  • smooth surface finish for improved hydraulic efficiency
  • multiple hydraulic designs for best customer fit
  • optional wear rings available to restore “as built” clearances
  • variety of materials available for different services

Continuous channel mulitvane diffuser and stage piece

  • eliminates one mating interface
  • provides additional rigidity for more reliable operation
  • simplifies maintenance procedures and reduces inventory requirements
  • smoothly directs the flow from stage to stage more efficiently
  • eliminates radial loads to assure longer bearing life

Wear rings

  • allow restoration of “as built” clearances
  • protect more expensive parts from wear
  • casing rings are standard
  • impeller rings are an option

Involute Balance Drum

  • provides axial thrust balance
  • insures rotor stability
  • prevents bearing failure from excessive thrust loading
  • small clearance minimizes leakage and improves efficiency
  • dual step surface protects against seizing or galling
  • accessible and removable from the discharge side of the pump

Suction and discharge casings

  • provide flexibility for customer piping layout 
  • radial and end suction configurations are available for the suction casing
  • discharge casing is dual volute type
  • radial suction casing and discharge casing can have nozzles positioned in 90O increments to allow customer flexibility in plant layout and equipment location.

Bearing housings

  • housings on the radial suction pump are identical on both ends
  • Inpro VBXX-DTM labyrinth seals protect bearings from contamination
  • made of high strength cast ductile iron and finned for additional cooling
  • cooling fan for additional thrust bearing cooling on the 5” and 6” sizes
  • bearing housings are configured to accept bearing temperature detectors and vibration instrumentation

Bearings

 - end suction (ES) configuration

  • suction side bearing is product lubricated
  • asymmetric trailing edge rib supports eliminate an additional stage for bearing support
  • support rib trailing edge design provides smoother flow into the impeller
  • discharge side bearing is a heavy duty, oil lubricated anti-friction bearing

 - radial suction (RS) configuration

  • same bearing housing and anti-friction arrangement as used on the ES discharge side is used at both ends of the radial suction pump
  • anti-friction bearings are oil lubricated

i-ALERTTM

  • i-ALERTTM condition monitor is standard
  • identifies unacceptable changes in vibration and temperature from an accepted operating baseline
  • provides an early visual alert of a potential problem

Applications

  • Reverse osmosis
  • Boiler feed
  • Shower
  • Spray
  • Cogeneration
  • Pressure boosting
  • High pressure cleaning
  • Snow making
  • Condensate
  • Mine dewatering
