SULZER & AHLSTROM REPLACEMENT PROGRAM
ZPP split-case
replacement pumps.
Replace an installed Sulzer ZPP double-suction, axially split pump. Match the duty, casing interfaces, rotation and driver arrangement, with a clear scope for complete-pump or component supply.

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 pump and what stays.
ZPP is a double-suction, axially split, single-stage configuration. The exact model, size and assembly data establish the replacement route.
Retained equipment
Installed configurationDriver, base or selected pump components
Information to sendIdentify what stays and provide its dimensions, drawings and condition.
Installed-family technical reference: Sulzer ZPP range.
02 / ENGINEERING FIT
Check the casing,
shaft line and duty.
The supply boundary determines which interfaces must match. A complete replacement and a component replacement need different approval information.
Double-suction duty
Flow, head, speed, suction pressure, fluid properties and available NPSH for the installation.
Recorded inHydraulic selection basis
Casing & mounting
Nozzle sizes and orientation, split-case geometry, centerline, mounting footprint and service access.
Recorded inGA & casing interfaces
Rotation & driver
Rotation with its viewing direction, shaft and coupling dimensions, driver rating and arrangement.
Recorded inShaft-line & driver details
Retained assembly
Part numbers, BOM, assembly drawings and mating dimensions for any components that remain.
Recorded inComponent scope & interface record
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
Two routes. One clear supply scope.
Choose the route that matches the condition of your installed equipment. Record supplied and retained items in the quotation and approval drawings.
Complete pump or bare pump
For an obsolete unit, a duplicate duty or a wider replacement. Define the driver, coupling, guard and baseplate scope.
Request pump replacementSelected components
For a serviceable retained assembly. Send part numbers, BOM or assembly drawings and describe the mating interfaces.
Request a component reviewApproved 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 commissioningWhichever occurs first.
Recorded in the written supply terms.

Can I replace components while retaining the casing or assembly?
Send the exact model, part numbers or BOM, assembly drawings and the dimensions of mating components. The component proposal identifies what is supplied and the interfaces with the equipment you retain.
How should I describe pump rotation?
State clockwise or counterclockwise together with the viewing direction, and mark it on a photo or drawing. A direction without a viewing reference can be ambiguous.
Do you supply a complete pump or a bare pump?
Both routes can be reviewed. Define whether the motor, coupling, guard and baseplate are supplied or retained. Include the driver and installation information for the chosen boundary.
What if I do not have a component part number?
Start with the nameplate, clear component photos, assembly drawings and available measurements. We identify the additional details needed to define the component and its mating interfaces.
What matters when retaining part of a split-case assembly?
The review includes split-joint geometry, fit and alignment interfaces, shaft and rotating-element details, sealing and the condition of retained parts. Provide the assembly information and identify the proposed supply boundary.
What records define the agreed replacement?
The proposal and approval drawings record duty, dimensions, materials, supplied equipment and retained interfaces. The order also defines inspections, test records, operating documents, delivery milestones and written warranty terms.
