SULZER & AHLSTROM REPLACEMENT PROGRAM
ZE / ZF & legacy ZA
replacement pumps.
Replace an installed Sulzer ZE, ZF or legacy ZA pump with a configuration matched to its duty and installation. Define pressure, temperature, nozzle and seal requirements before approving the replacement.

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
Separate the current and legacy routes.
ZE / ZF and legacy ZA installations need their own model and drawing basis. Record the exact installed series in your enquiry.
Legacy ZA
Installed configurationModel-specific legacy replacement
Information to sendNameplate, existing drawings or measured installation interfaces.
Project specification
Specify the required API 610 / ISO 13709 edition, inspection scope and acceptance criteria in your RFQ. The replacement proposal records the requirements and any deviations for project approval.
Review a legacy ZA installation
Installed-family technical reference: Sulzer ZE / ZF range.
02 / ENGINEERING FIT
Start with pressure,
temperature and interfaces.
A dimensional match is one part of the selection. The pressure boundary, thermal behavior, sealing and driver arrangement must follow the project duty.
Duty & pressure boundary
Flow, head, suction pressure, maximum discharge pressure, temperature and required nozzle ratings.
Recorded inDuty & design-condition schedule
Hot-service installation
Nozzle orientation, centerline, supports, mounting dimensions and the installation’s thermal movement requirements.
Recorded inGA & installation interfaces
Seal & auxiliaries
Installed seal, flush or cooling arrangement, utility connections and specified seal-plan requirements.
Recorded inSeal & auxiliary-system scope
Driver & project requirements
Speed, power, coupling, retained driver and the specified materials, inspections and acceptance criteria.
Recorded inDatasheet & compliance review
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
Make the supply boundaries explicit.
Choose a complete pump set or define a bare-pump or assembly scope around retained equipment. Include the project specification and seal-system requirements. The proposal lists the supplied equipment, retained interfaces, inspection points and approval documents together.
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.
Delivery & operation
Equipment identification, packing list, operating documentation and the written delivery and warranty terms.
WARRANTY

Is a legacy ZA replacement the same as ZE / ZF?
It is a separate model-specific route. Send the full ZA model and available drawings or measurements. We establish the installed duty and interfaces rather than assuming that a ZE / ZF configuration fits.
What if the original GA drawing is unavailable?
Start with the nameplate and clear installation photos. We provide the dimensional information needed for the review, including nozzles, centerline, mounting holes and coupling interfaces. The approval GA records the agreed dimensions.
What information is needed for high-temperature service?
Include operating and design temperatures, fluid properties, suction and discharge pressures, seal and cooling arrangements, and any installation constraints related to thermal movement. Add the project datasheet and specification when available.
What if I do not know the seal plan?
Send photos of the seal area and auxiliary piping, seal identification and available drawings. We identify the existing arrangement and agree the replacement’s seal and utility scope in the proposal.
Can the existing driver and base be retained?
Yes, where the agreed configuration uses them. Provide driver rating and speed, shaft and coupling details, base dimensions and condition information. The review records which components remain and which are supplied.
Does every replacement include the same API tests?
The project specification defines the required standard edition, inspections, tests, witness points and documentation. These are listed in the quotation and inspection plan. Materials, testing and delivery documents follow that agreed scope.
