100% Air-Leak Tested Proven Seal Core

PROGRAM OVERVIEW
What FBU delivers for Pump OEMs
For OEM customers, the cartridge seal is part of the equipment platform. FBU configures the seal around your pump, manages the engineering and manufacturing responsibility, and supports you through drawings, documentation, repair kits, configuration control, and repeat production.

01

Adapt a Proven Seal Core

FBU begins with a mature seal-core architecture instead of unnecessarily redesigning the complete seal for every project. This creates a repeatable engineering and manufacturing foundation.

02

Configure for Your Equipment

The sleeve, gland, equipment interface, materials, and applicable supporting features are configured around your pump, operating requirements, and validation standards.

03

Reduce Repeated Development

Leverage the same proven internal architecture across similar pump platforms, reducing development risk and speeding up new equipment introduction.

04

Approved Drawings & BOMs

Establish approved drawings, bills of materials, and OEM part numbers with clear revision and configuration control through FBU’s PLM system.

05

Move from Prototype to Serial

Validate the prototype, freeze the configuration, then move to repeat production with predictable lead times and traceability.

06

Controlled Aftermarket Program

Build a controlled replacement and repair-kit program tied to your OEM part numbers, protecting your installed-base aftermarket revenue.

CHINA MANUFACTURING INTEGRATION
The right seal—before the pump leaves China
For independent pump brands that manufacture, outsource, or source pump heads and complete pumps in China, the mechanical seal can become a point of divided responsibility. With the brand owner’s authorization, FBU coordinates directly with the nominated Chinese pump factory while your salesperson continues to manage the brand-customer relationship.

Confirm Interfaces

Shaft, sleeve, seal-chamber, gland, and installation interfaces are verified against the pump drawing before the seal is finalized.

Coordinate Installation & Testing

FBU supports cartridge seal installation and participates in pump-performance testing at the nominated factory.

Supply Test & Backup Seals

Reusable dedicated test seals, repair kits, and backup seals are prepared to keep pump commissioning on schedule.

Freeze Configuration

Approved configuration, customer part numbers, BOMs, and replacement information are recorded for repeat supply.

CUSTOMER DELIVERABLES
Every cartridge seal is supplied with
FBU supplies a complete cartridge seal assembled and tested at the factory. The customer receives an installable unit with defined configuration responsibility, rather than a collection of components that must be matched and assembled locally.

Identification

Clear product identification and a unique serial number for traceability.

Drawings

Outline and installation drawing, plus applicable installation information.

Certificates

Certificate of Conformity and an air-leak test report for every applicable complete cartridge seal.

Documentation

Packing documentation; inspection records are retained for traceability.

FROM PROTOTYPE TO SERIAL PRODUCTION
A clear path from first unit to
repeat supply
A new supplier relationship does not need to begin with a large product program. Start with one pump model, one duty point, or one China-manufactured pump project.

01

Send What You Have


Start with a pump model,existing seal information,drawing,dimensions, photos,or a failed seal sample.

02

Define What Is

Missing

FBU identifies available information and lists the additional data required for proper seal selection.

03

Review the

Application

Review equipment interfaces, operating conditions, materials,standards, documentation, and testing requirements.

04

Propose the

Configuration

Receive the recommended configuration, materials, technical boundaries, quotation, lead time, and required confirmations.

05

Approve the Drawing


Confirm outline, installation dimensions, interfaces, materials, and applicable project requirements.

06

Manufacture & Test


FBU manufactures critical components, completes inspection, assembles the cartridge, and performs air-leak testing.

07

Deliver the Prototype


Receive product identification, drawings, installation information, Certificate of Conformity,and test report.

08

Validate the

Application

Complete installation, pump testing, or field validation with remote or China-based coordination.

09

Freeze the

Configuration

Freeze drawing, materials,BOM, customer part number, internal part number, and revision status.

10

Repeat Production


Move to serial supply, repair kits, replacement seals, configuration control, and change notification.


MANUFACTURING UNDER CONTROL
Critical components made and inspected in Suzhou.
The purpose of this control is not simply to show equipment. It is to provide repeatable dimensions, controlled configurations and evidence that customers can verify.

HAAS Machining

Sleeves, glands, seal ring holders and other critical metal parts machined in-house.

Precision Inspection

Dimensional inspection applied to critical dimensions according to the inspection plan.

ZEISS Inspection

Applied to selected critical dimensions and components per the inspection plan.

Controlled Assembly

Factory cartridge assembly under controlled procedures and environments.

Static Air-Leak Testing

Every applicable complete cartridge is air-leak tested before shipment.

SAP + PLM Control

Order, drawing, BOM and product-data management connected through SAP and PLM.

Start with one pump model.
A new supplier relationship does not need to begin with a large product program. Send FBU the information currently available, and we will identify what is known, what still needs to be confirmed and what validation is appropriate.
