SULZER & AHLSTROM REPLACEMENT PROGRAM

AHLSTAR replacement pumps.
Engineered to fit.

Replace your installed Sulzer or Ahlstrom AHLSTAR pump without changing piping or foundations. We match the duty, process conditions and installation interfaces, then record the configuration in your approval drawings.

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

Identify the exact AHLSTAR series.

The family name is the starting point. Send the full model and size so we can match the hydraulic and mechanical configuration.

A / APT

Installed configurationGeneral process service

Information to sendFull model, pump size, duty and installed arrangement.

WPP / WPT

Installed configurationWear-resistant process service

Information to sendSolids concentration, particle size and abrasive characteristics.

NPP / NPT

Installed configurationNon-clogging process service

Information to sendSolids, fibers and the fluid handling requirements.

EPP / EPT

Installed configurationHigh-temperature process service

Information to sendOperating and design temperatures, seal and thermal requirements.

Installed-family technical reference: Sulzer AHLSTAR A range.

02 / ENGINEERING FIT

Keep the interfaces.
Match the process.

A replacement must fit the installation and handle the actual fluid. These checks define the proposed pump and the information you approve.

01

Hydraulic duty

Flow, head, speed, operating range and available NPSH, including any change from the original duty.

Recorded inDuty selection & pump curve
02

Installed geometry

Suction and discharge flanges, nozzle orientation, centerline, mounting holes and baseplate dimensions.

Recorded inGA & interface drawing
03

Fluid & wetted materials

Temperature, chemistry, viscosity, solids or fibers, and the specified corrosion or wear resistance.

Recorded inMaterial & process specification
04

Seal & retained driver

Seal arrangement, flush connections, rotation, coupling and the condition of any retained motor.

Recorded inAssembly & supply boundaries
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

Choose what you replace.

A complete pump is the primary route. If you retain the driver or base, request a bare pump or assembly and include the coupling and mounting details. For a wet end or selected components, send the part number, BOM or assembly drawing so the retained interfaces are included in the review.

Discuss my supply scope

Approved 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.

Delivery & operation

Equipment identification, packing list, operating documentation and the written delivery and warranty terms.

WARRANTY

18 months from shipment / 12 months from commissioning

Whichever occurs first.
Recorded in the written supply terms.

  1. 01 / SEND

    Your installed pump data

    Start with the model or nameplate, duty and available drawings.

  2. 02 / REVIEW

    Report or proposal in 48 h

    From sufficient information, with the fit and supply scope recorded.

  3. 03 / APPROVE

    Agree the project basis

    Confirm drawings, materials, inspections, tests and delivery milestones.

  4. 04 / DELIVER

    Complete pump in 6–8 weeks

    Manufacture and delivery follow the agreed order schedule.

04 / START YOUR REPLACEMENT

BEFORE YOU ENQUIRE

AHLSTAR replacement.
Clear answers.

View the replacement program
How do I identify my AHLSTAR series?

Send a clear nameplate photo showing the manufacturer, full model, size and serial number. Include an overall installation photo. We identify the series and explain which duty or dimensional information is needed next.

What extra data helps with WPP/T or NPP/T replacement?

For wear-resistant service, include solids concentration, particle size and abrasive characteristics. For non-clogging service, describe fibers, solids and fluid behavior. These details guide the hydraulic arrangement and wetted material selection.

Can I keep my piping, foundation and motor?

We match piping and foundation interfaces to your installed configuration and record the dimensions in the project GA. A retained motor also needs its rating, speed, shaft, coupling and mounting checked against the selected replacement.

Can you start without the original pump curve?

Yes. Send the model, available flow and head, fluid information and installation photos. Operating readings and measurements help reconstruct the duty basis; the review identifies any information still required for final selection.

Can you supply a complete pump, bare pump or wet end?

Yes. State the requested scope in the enquiry. The proposal identifies the pump, motor, coupling, guard, baseplate and any retained equipment. A wet-end or component supply is matched to the relevant assembly interfaces.

What delivery, documents and warranty are included?

Complete-pump delivery is 6–8 weeks against the agreed order schedule. Each unit includes the specified material, testing and delivery documents. Warranty is 18 months from shipment or 12 months from commissioning, whichever occurs first, under the written supply terms.
