Recently, Jiashan Yongbang Seals Co., Ltd. completed a large-scale shipment of customized mechanical seals (TB2P40, TB1F30, and Grundfos 12mm/16mm/22mm series) for a new valued client from Brazil with a substantial order volume. This large initial order serves as solid proof of the client’s recognition of our premium product quality, as well as testament to Yongbang’s reliable product strength and growing market influence in Brazil’s industrial sealing market.

Precision-engineered Quality for Harsh Brazilian Working Conditions
Compliant with international industrial pump sealing standards and Brazil’s tough local operating environments, all exported TB series and Grundfos-spec mechanical seals follow Yongbang’s rigorous standardized manufacturing and quality control system to secure stable and durable performance from raw material selection to finished product inspection:
- Premium Grade Material Formulation: TB2P40 and TB1F30 series mechanical seals are equipped with high-precision friction pairs, corrosion-resistant stainless steel housings and high-performance HNBR/Viton elastomers, delivering stable pressure and temperature resistance. The compact Grundfos 12mm, 16mm and 22mm seals feature outstanding chemical and salt corrosion resistance. All products are well adapted to Brazil’s tropical humid climate and complex workin
- Comprehensive Factory Testing: Every single mechanical seal undergoes strict pre-shipment tests including tightness inspection, pressure resistance test, leakage detection and fatigue endurance testing. This full-process testing mechanism eliminates hidden risks such as seal leakage, premature wear and operational failure, effectively reducing end users’ equipment downtime and daily maintenance costs.

Efficient Standardized Export Process Ensures Punctual and Safe Delivery
- Different from small-batch trial sample orders, this large consignment is the client’s first formal bulk purchase after technical verification and demand confirmation. To guarantee zero errors in export delivery, the Yongbang team achieved efficient full-process coordination, covering demand confirmation, parameter optimization, mass production scheduling, multi-round quality inspection and standardized export packaging. Supported by our complete independent production and supply chain system, all production and testing tasks were completed strictly on schedule.
- Meanwhile, we sorted out complete sets of material certificates, test reports, inspection documents and customs clearance materials in full compliance with Brazilian cross-border trade and industrial import standards. Complete and standardized document support ensures smooth customs clearance and safe, timely arrival of goods for the client.
