Dear Valued Customer,

We are pleased to inform you that our company has recently invested in and commissioned a state-of-the-art sealing integrity test system specifically designed for submersible bilge pumps.

This new equipment allows us to perform highly accurate, non-destructive leak testing on all critical sealing points, including pump housings, cable entries, seal chambers, and mechanical shaft seals.

Key improvements for you as our customer:

Enhanced product reliability – Each pump is rigorously tested to ensure watertight integrity under real-world submerged conditions

Reduced risk of field failures – Early detection of micro-leaks prevents premature seal-related breakdowns

Full traceability – Electronic test records with pass/fail thresholds for every unit

Faster quality assurance – Automated testing reduces lead times without compromising precision

This investment is part of our ongoing commitment to delivering high-quality, durable submersible pumping solutions.

Should you have any questions regarding our quality control procedures or require test documentation for a specific order, please do not hesitate to contact us.

Thank you for your continued trust and partnership.

Sincerely,

Xiamen Newmao Pump Industry Co., Ltd
