This high-performance tungsten carbide mechanical seal is engineered as a direct OEM replacement for SPX APV mechanical seal models (W+, Puma, V2 series). Designed for extreme conditions, it upgrades standard ceramic or carbon seals with superior durability and chemical resistance.

Mechanical shaft seals are engineered specifically for APV pump systems, delivering reliable sealing performance in demanding sanitary, food, beverage, and pharmaceutical applications. Designed to meet stringent hygienic and safety standards, these seals ensure zero leakage, easy cleanability, and long service life. 

This high-performance APV pump mechanical seal is engineered as a direct OEM replacement for SPX APV W+, V2, and World series pumps. Designed for sanitary applications, it provides a reliable, leak-free solution for food, dairy, and beverage processing.

The APV mechanical seal is a high-performance, precision-engineered sealing solution designed specifically for APV sanitary centrifugal pumps and mixers in the food, dairy, beverage, and pharmaceutical industries. Engineered for reliability, this seal is available in five standard shaft diameters: 20mm, 22mm, 24mm, 25mm, and 28mm. Whether you need a mechanical seal 20mm for compact agitators or a mechanical seal 28mm for high-flow pumps, this product line offers a direct OEM replacement with superior material options.

This Type 301 rubber bellows mechanical seal is a direct-dimension replacement designed for legacy APV® end-suction centrifugal water pumps — including certain Premier series models and early World Series utility pump variants that utilize a bellows-type seal chamber. Unlike modern wave-spring hygienic cartridge seals (APV W+ type), this type 301 mechanical seal features a one-piece nitrile (NBR) or EPDM rubber bellows rotating assembly that combines the secondary seal, drive mechanism, and spring function into a single component.

The flexible bellows design compensates for shaft run-out, vibration, and minor misalignment common in aging pump installations — eliminating the need for set screws or drive pins that can slip on worn shafts. The standard face combination of resin-impregnated carbon graphite rotating against a 99.5% alumina ceramic stationary seat provides reliable sealing for clean water, softened water, cooling water, and light mineral oils at temperatures up to 100°C (NBR) or 120°C (EPDM).

Available in common fractional-inch shaft diameters from 3/8″ to 1″ (9.5–25.4 mm), this type 301 mechanical seal is a cost-effective, drop-in replacement for maintaining legacy APV pump installations without expensive conversion to modern cartridge seal chambers.

A wave spring mechanical seal engineered as a direct OEM replacement for SPX APV centrifugal pumps, available in mechanical seal 40mm and mechanical seal 45mm shaft diameters to fit W, W+, and PUMA series. The open sinusoidal wave spring design resists product entrapment during CIP/SIP cycles, making this APV pump mechanical seal ideal for dairy, beverage, pharmaceutical, and food processing lines. With balanced face loading, compact axial length, and optional SiC/SiC or Carbon/SiC face combinations, our wave spring seals deliver hygienic, leak-free performance in viscous or particulate-laden fluids.

The silicon carbide stationary mechanical seal is a precision-engineered sealing solution designed specifically for the demanding requirements of sanitary, high-purity, and chemically aggressive applications in industries such as food and beverage, pharmaceuticals, biotechnology, and chemical processing. APV pumps, known for their hygienic design and reliability in handling sensitive fluids, benefit from this silicon carbide mechanical seal's exceptional material properties and performance characteristics.
