KSB Omega Replacement Pumps
Engineered replacement review for installed split-case pumps. Start with the existing model, duty point, nameplate and GA drawing, then verify hydraulics and installation dimensions before quotation.
Turn an installed pump into a verified replacement package
Use the engineering evidence required to avoid pipe, baseplate or coupling surprises during retrofit.
Identify
Existing manufacturer, full model designation, serial / nameplate ID.
Match Duty
Flow, head, speed, frequency, liquid and temperature.
Verify Fit
Flanges, shaft centerline, footprint, rotation and coupling interface.
Quote Scope
Bare pump, complete pump set, or project-specific replacement package.
Build the engineering review package
This review collects the installed pump identity, duty point and interface data needed for an engineering replacement assessment. If the duty point is unknown or has changed, start with the Split Case Pump Selection & Performance Guide.
Confirm the installed pump before final replacement selection
Use the existing nameplate, GA drawing and duty data to verify the four essentials below.
Model Identification
Capture the full model and serial or nameplate reference.
GA Comparison
Compare flanges, centerline, footprint and shaft interface.
Hydraulic Review
Confirm flow, head, speed, impeller trim and NPSHr.
Material Review
Confirm casing, impeller, shaft and seal requirements.
Six engineering checks that matter more than a matching model name
These items become the proof framework for the final replacement recommendation.
Centerline & Footprint
Check center height, feet, anchor-bolt positions and foundation constraints.
Flange Arrangement
Check suction/discharge size, location, drilling and connection orientation.
Shaft & Coupling
Check shaft extension, coupling interface, rotation and motor reuse requirement.
Hydraulic Mapping
Compare Q/H, rpm, impeller trim, efficiency and NPSH requirement.
Seal & Materials
Confirm shaft seal, casing, impeller and wetted-material requirements.
Supply Scope
Choose Bare Pump, Pump + Baseplate, Pump + Motor + Baseplate, Replacement Components / Parts, or another project-specific scope.
Review replacement materials against the actual service
Review the catalog options below against liquid, temperature, wear and corrosion conditions.
| Component | S-Series catalog options | Replacement review |
|---|---|---|
| Pump casing | HT250 / QT400-18 / ZG230-450 | Compare existing casing material and service condition. |
| Impeller | ZCuSn10Pb1 / HT250 / ZCuZn16Si4 / ZG1Cr18Ni9Ti | Review liquid chemistry, wear and corrosion requirement. |
| Shaft | 2Cr13 / 45# | Review environment and mechanical requirements. |
| Seal ring | ZCuSn10Pb1 / HT250 / ZCuZn16Si4 / ZG1Cr18Ni9Ti | Review wear pair and liquid compatibility. |
Search the installed model, then start a verified review
Search the installed model and continue with a documented engineering review.
Enter the existing model
No model selected
Enter the installed model to create a replacement-review state.
Rebuild the operating condition before forcing a cross-reference
If the plant duty has changed, the original nameplate is incomplete, or Q/H is uncertain, use the Split Case Pump Selection & Performance Guide first.
Open Selection & Performance GuideBare pump or complete replacement set
Choose the supply scope that matches the replacement project.
Bare Pump
For projects retaining the existing driver or site-specific drive arrangement.
Complete Pump Set
Pump, motor and baseplate package for broader retrofit scope.
