FBU coordinates only with customer authorization
and does not bypass the equipment brand.
Without seal control
The pump factory selects a low-cost seal for testing. The US brand later buys the application seal, replaces it in the US and still lacks reliable seal documents for future spares.
With FBU integration
The pump factory selects a low-cost seal for testing. The US brand later buys the application seal, replaces it in the US and still lacks reliable seal documents for future spares.
On-site pump-factory coordination
Final application seal in pump test
Standby repair kit or replacement seal
Reusable dedicated test-seal option
A pump hydraulic/performance test confirms installation and operation under the agreed test condition. It does not by itself prove every field duty or full API 682 compliance. Project validation is defined separately.
