For municipal water, drinking water pumping, and water treatment systems, safety, compliance, and uptime are non-negotiable. TF Seals is proud to offer three industry-trusted mechanical seals fully certified to NSF/ANSI/CAN 61—meeting North America’s strictest standards for drinking water contact, with zero harmful leachable and full regulatory confidence.

PZ46 Cartridge Mechanical Seal

Comprehensive and cost-effective sealing solution for industrial liquid applications. Designed for rotating shaft equipment such as ANSI/DIN pumps, close-coupled pumps, vertical pumps, and similar machinery, this series conforms to key industry pump standards and is readily available.

PZ47 Cartridge Mechanical Seal

Reversible, non-clogging, and engineered for greater durability. Features an optimized seal face and external wave spring to resist debris, fitting a wide range of standard seal chambers. Perfect for demanding water applications where consistent, low-maintenance sealing is critical.

SP01 2-Piece Split Mechanical Seal

The ultimate solution for minimizing downtime. This split seal installs without disassembling the pump or removing the motor, slashing maintenance hours. NSF 61 certified, leak-tight, and designed for large shafts and hard-to-access installations—keeping water systems online longer.

All three models are third-party certified, lead-safe, and engineered to protect public water quality while delivering long service life and dependable performance.
