A versatile modular cartridge seal family offering interchangeable elastomer bellows, metal bellows, and elastomer O-ring pusher configurations. The Type PZ47 single seal uses an elastomer O-ring as the secondary seal; the common seal head/mating ring set is reversible (rotating seat or rotating seal head) and compatible with metal bellows seal heads. PZ47Q adds a quench option via carbon ring throttle bush. Certified to NSF/ANSI/CAN 61 for potable water contact.

Design Features

Reversible seal head for versatile use
Fits ANSI B73.1M, ISO 3069, DIN 24960 chambers
Optimized primary ring design for enhanced reliability
External non-clogging wave spring

Dual Cartridge Type

PZ47D

Dual seal arrangement with an elastomer O-ring dynamic secondary seal. Reverse-balanced primary and mating rings enable ID or OD pressurization, so the seal can run as either a tandem or double seal — OD pressurization of the outboard seal minimizes tensile stress, improves cooling, and aids air venting on vertical installs.

Design Features

Reversible seal head design
External non-clogging wave spring
ANSI B73.1M / ISO 3069 seal-chamber compatible
Primary ring optimized for enhanced reliability
Outboard seal drive without set screws
Tangential inlet/outlet pipe connections below 3.000"/75mm

Specifications

Temperature: -20°F to 400°F (-30°C to 205°C)
Pressure: up to 21 barg (300 psig) ≤75mm; 13 barg (200 psig) >75mm
Speed: up to 25 m/s (5,000 fpm)
Axial float/end play tolerance: 0.13mm (0.005")
Runout/squareness tolerance: 0.05mm (0.002")

Advanced Seal Face Technology

TF REAL DIAMOND — CVD Coating

Diamond Coated Seals & Bearings (TF REAL DIAMOND)

Diamond is forever. TF REAL DIAMOND is applied to mechanical seal faces through Chemical Vapor Deposition (CVD) technology, offering exceptional protection for rotating surfaces. With unmatched hardness, exceptional resistance to chemical attack, and ultra-low friction, this coating significantly reduces wear and extends seal life. Diamond is coated directly onto existing silicon carbide seal rings and bearings — no design change is needed. Simply replace the uncoated components with diamond-coated ones.

Advantages

Largest known electrochemical potential window of all electrode materials
Low background, excellent chemical inertness
Reduced fouling compared to other electrode materials
Withstands extreme potentials, corrosive and high temperature/pressure environments

Applications

Petrochemical industry
Mining industry / slurry applications
Pharmaceutical & chemical industry
Power plant technology & special applications
