Discharge Head
Patented “O” Head design provides consistent flow and eliminates potential resonance frequencies through a comprehensive Finite Element Analysis.
Impeller
Optimum hydraulic balance conditions achieved by eliminating balance holes. Prototypes developed from geometrically similar model impellers, tested to ensure peak performance in the field.
Wear Rings
Reduce downtime and costly repairs with addition of this option on the impeller and diffuser/suction bell. Wear rings are made of hardened alloys and easily replaceable to renew design-running clearances.
Diffuser
Recover the velocity head by straightening the flow of the impeller with this carefully crafted element.
Suction Bell
Separately cast, precision component, provides a smooth flow to the impeller eye, with minimized submergence requirements.
Column and Elbow
Column pipe is fabricated in discrete sections to provide intermediate guide bearings required. Elbow can be arranged for either above or below floor discharge required on specific applications.
Computational Fluid Dynamic Analysis
Determines the sump flow conditions at the pump inlet for superior pump performance.
Critical Speed Analysis
Ensures that the first critical speed is well above the maximum operating speed of the pump.
Mechanical Design Analysis
Defines the proper shaft size and configuration along with other critical design features.
Model Test Data
Validates geometrical similarity between pump models and full-size pumps. Aids in casting, fabrication, machining and inspection in pump manufacturing. No need for costly fullsize testing.
Start-Up Analysis
Identifies the optimal starting sequence between the pump, driver and discharge valve. Determines ability of pump to start under adverse conditions.
Pump Quality
Inspection of all pump components and assemblies to ensure reliable operation, meeting the standards of the Hydraulic Institute.
-Power generation cooling (main, intermediate and secondary water circulation)
-Condenser cooling with maximum efficiency
-Desalination sea water intake across the globe
-Flood protection in storm ravaged areas
-Waste treatment plants (industrial and municipal)
-Industrial services including descaling, cooling, quench process, fire protection and API services
-Cantilever impeller design eliminates the tail bearing and lowers NPSH values. This improves fluid inlet conditions and hydraulic performance.
-Want added stability? We support the upper bearing above the first stage impeller by adding an extra length or double bearing.
Shaft
Transmits maximum power at well below the pumps’ first critical speed. Strict control of shaft straightness provides dependable operation and longer service life.
Shaft Sleeves
Optional feature at all bearing sleeves and at the stuffing box locations. This hardened alloy alternative protects the shaft and extends service life. Designed for easy replacement and maintenance.
Bearings
Protected from high pressure pumpage and contaminants, our bearings are isolated inside enclosing tubes in the column pipe as an alternative. A separate, clean fluid source lubricates bearings and seals, causing less abrasion and wear.
Intermediate Coupling
This transmission of power and rotation through the shaft is driven by coupling keys. Thrust loads are transmitted through the split ring design.
Rigid Adjustable Drive Coupling
Coupling keys and split thrust ring design transmit the torque, hydraulic thrust and pump rotating weight to the driver. Also provides clearance adjustment between the wear rings.
Stuffing Box
Packed with flexible graphite material to reduce resistance and prolong shaft service life. A split gland simplifies packing adjustment and replacement.
-Gone are the headaches of disconnecting and reconnecting pumps from bulky, below-grade discharge pipes
-Our “Pull-Out” option allows easy removal of the inner element of the pump for maintenance, eliminating the need to drain or enter the pump.
-Suction bell, column, discharge elbow and discharge piping are not disturbed. Downtime and repair costs are greatly reduced when worn parts are replaced, restoring system efficiency.
-Sliding and conical fit ensure proper alignment upon reassembly.
-Available on all ITT Goulds Pumps’ Vertical Pump models. Column size for a given capacity is not affected by “Pull-Out” design, with no loss in pumping performance.
-Our shaft enclosing tube insulates the shaft from the pump fluid and provides a passage for bearing lubrication.
-One end of the shaft tube has an O-ring sliding fit for thermal expansion. Easy to disassemble and reinstall.
-Goulds Pumps Engineering utilizes sophisticated 3D design tools to create scalable models of every custom pump. Each model undergoes extensive testing to optimize it for specific hydraulic applications.
-Other hydraulic enhancements include a Suction Bell with flared inlet controls to accelerate fluid to the desired inlet velocity.
-Outer walls on the bowls provide structural integrity, with flange fits located at each end for positive alignment.
-The contour of the diffuser/bowl provides accurate fit to the impeller, maximizing operating efficiency.
