SULZER & AHLSTROM REPLACEMENT PROGRAM
SNS replacement pumps.
Matched to your duty.
Replace your Sulzer SNS end-suction process pump without changing piping or foundations. Match the actual operating point, installation geometry, fluid and driver in one documented replacement proposal.

Delivery follows the agreed order schedule; the 48-hour review starts with sufficient pump and duty information. The project GA records the exact installed interfaces.
01 / IDENTIFY THE CONFIGURATION
Define the duty you need today.
Use the nameplate to identify the installed unit, then distinguish the original selection from current operating conditions.
Current duty
Installed configurationKeep the duty or accommodate a process change
Information to sendRequired flow and head, fluid, operating range and available NPSH.
Installed-family technical reference: Sulzer SNS range.
02 / ENGINEERING FIT
A physical fit.
A hydraulic match.
Retaining pipework is useful only when the replacement also suits the system. The selection connects operating conditions to the installation dimensions.
Operating point & range
Required flow, head, speed and the operating range, including any process change from the existing duty.
Recorded inSelection basis & pump curve
Suction conditions
Available NPSH, inlet conditions, fluid temperature and the selected pump’s required NPSH.
Recorded inSuction & NPSH review
Installation geometry
Flange size and orientation, centerline, mounting footprint, rotation and maintenance access.
Recorded inGA & dimensional match
Fluid, seal & driver
Chemistry, viscosity, solids or fibers, wetted materials, seal arrangement and any retained motor.
Recorded inMaterials & mechanical scope
Review the match before manufacture.
Your report identifies the proposed configuration, agreed dimensions, supply boundaries and any data still required. Approval drawings establish the manufacturing basis.
03 / SCOPE & DOCUMENTS
Keep suitable equipment in service.
Request a complete pump set, or a bare pump or assembly around a retained motor and base. Include driver power, speed, shaft and coupling details. For component supply, send the part number or assembly drawing and identify what remains in service.
Discuss my supply scopeApproved configuration
Duty and interface drawings, material and seal specification, driver requirements and a clear equipment list.
Material & test records
Specified material identification and traceability, inspections and test reports to the agreed project requirements.

Which dimensions are needed to retain my piping?
Provide suction and discharge flange sizes and orientation, centerline height, nozzle positions, mounting holes and baseplate dimensions. The project GA records the installed interfaces and proposed replacement dimensions.
Can the replacement handle a different operating point?
Yes. Identify the required flow, head, speed and operating range separately from the original duty. We select against the updated conditions and review suction conditions, motor power and installation requirements together.
Can you review an SNS pump without its original curve?
Yes. Send the full model, available duty information, fluid details and operating readings. Photos and installation measurements help establish the replacement basis; the report identifies the remaining data needed for selection.
What fluid details matter for materials and sealing?
Include fluid composition, temperature, viscosity, solids concentration and particle or fiber characteristics. Add any corrosion, wear or seal history. These details help define wetted materials and the seal arrangement.
Can I keep the existing motor?
Provide the motor rating, speed, shaft, coupling and mounting information. We review power and mechanical compatibility against the replacement duty and record the retained-driver scope in the proposal.
How quickly can I receive a proposal and replacement?
We provide an engineering report or proposal within 48 hours of sufficient pump and duty information. Complete-pump delivery is 6–8 weeks against the agreed order schedule, with the specified material, testing and delivery documents.
