UNCD Type A05 Seals for Evaluation

Product Description

UNCD^® Type A05 seals are long-lasting, wear-resistant diamond multi-spring pusher component seals that feature the patented UNCD form of diamond. O-rings are used as secondary sealing elements. Components use a snap-ring design and are able to be shaft mounted.

A05 component seals are offered to enable end-users, OEM, and seal manufacturers a quick and easy method of procuring UNCD seals for pilot plant and evaluation purposes in common ANSI pump sizes. In addition to these A05 seals, UNCD Faces are offered to OEM and seal manufacturers in standard ANSI mating ring geometries and can be manufactured to your custom engineering drawings. Please contact us for further information regarding UNCD Faces for your products.

Applications and Features

These evaluation seals are designed for industrial applications including chemical, pharmaceutical, petrochemical, food and beverage processing, power generation, pipeline and pulp and paper. A05 seals are particularly suitable for poor lubricating environments including hot-water and applications that include temperature sensitive organics. Though the standard A05 configuration pairs a blister resistant carbon primary with a UNCD mating ring, A05 seals are also available in a "hard-on-hard" configuration with a silicon carbide (SiC) primary and UNCD mating ring. The coefficient of friction (CoF) of this hard-on-hard combination is between 0.02-0.04, well below the CoF values of carbon faces running against SiC. Additional technical details and performance testing results can be found here.

Media

UNCD seals are appropriate for industrial fluids, aqueous solutions, chemicals, corrosive liquids, high pressure liquids, lubricating fluid, hydrocarbons and solvents.

Sizes

Currently, the A05 Seal is offered in five sizes to accommodate ANSI pumps with shafts of 1.125" to 2.125" diameters. Alternate sizes can be special ordered. All seals are supplied with a rotary head and mating ring whose general design and geometry match the drawing to the left. DIN sizes are also available.
