PPC Mechanical Seals
Pioneer provides engineered mechanical sealing solutions from PPC.
Pusher Seals
1500E Seals
An economical stationary single-cartridge seal designed to provide dependable performance across a wide range of industrial applications.
1500 Single Cartridge Seals
A versatile line of stationary single-cartridge seals, with options ranging from the cost-effective 1500E to the more highly engineered 1500F.
1500EHD Seals
A heavy-duty stationary single-cartridge seal built for more demanding operating conditions and applications requiring added durability.
PPC P-3F Dual Cartridge Seal
A dual mechanical seal engineered to maintain reliable face alignment and flatness across changing temperatures and pressures. Stationary springs help accommodate stuffing box misalignment, while monolithic rotary faces reduce distortion.
Dual Gas Liftoff Seals
Available in double or tandem configurations for liquid-lubricated or dry-running service. These seals use buffer or barrier fluid between the seal faces, while the PPC 7000 provides a contacting dry-running option for zero-leakage applications.
682A Pusher Seals
A pusher-style mechanical seal with an O-ring secondary seal, available in single, tandem, and double arrangements to support a range of API applications.
Split Seals
1200S Split Single Seal
A streamlined split mechanical seal designed with fewer components to simplify installation while maintaining strong mechanical reliability.
2400S Split Double Seal
An advanced split double mechanical seal engineered to provide dual-seal performance without requiring complete equipment disassembly.
Metal Bellows Seals
1500ERB Seal
A general-purpose single-cartridge seal featuring Alloy C-276 metal bellows for strong corrosion resistance, reliable pressure performance, and reduced risk of dynamic hang-up.
Ultraseal 151
A welded metal bellows single-cartridge seal that eliminates dynamic O-rings by using the bellows as both the spring and sealing element.
Ultraseal 2000
A double or tandem metal bellows seal with OD-pressurized outboard faces and a standard integral pumping ring for dependable dual-seal performance.
Ultraseal 1700 High Temp Metal Bellows Seal
A high-temperature metal bellows cartridge seal engineered specifically for Viking Pump applications.
Ultraseal 400 Series Cryogenic Seals
Advanced cryogenic sealing solutions combining updated bellows technology with PPCF, a custom polymer material developed for demanding low-temperature service.
682B Metal Bellows Seals
API-style metal bellows seals with elastomeric secondary seals, available in single, tandem, and double arrangements.
682C High Temperature Metal Bellows Seal
High-temperature metal bellows seals with Grafoil secondary sealing, offered in single, tandem, and double configurations.
Engineered Seals
Reactor/Mixer/Agitator Autoclave Seals
PPC manufactures, repairs, and upgrades mechanical seals for reactors, mixers, agitators, and autoclaves. Available configurations include single, double, tandem, dry-running, pharmaceutical, large-diameter, and custom-engineered seals, with upgrade options such as bearings, pumping rings, cooling jackets, and balanced designs.
Slurry Seals
Built for abrasive and solids-heavy services, PPC slurry seals support demanding applications across mining, wastewater, petrochemical, power, food processing, pulp and paper, and other industries. Custom materials and diamond seal faces are available for severe operating conditions.
Boiler Feed Seals
PPC engineers boiler feed sealing solutions to improve cooling, vapor margin, and mechanical seal life. Available options include high-pressure seals, restriction bushings, multi-port injection, API Plan 21 and Plan 23 systems, and performance upgrades designed to increase mean time between failures.
Gas Seals
PPC provides single, tandem, and double gas seals for liquid, gas, and cryogenic applications. Contacting and non-contacting designs help reduce emissions, prevent product contamination, support dry-running operation, and lower maintenance requirements in demanding service.
Pipeline and Midstream Seals
PPC HB Single Cartridge Seal
A hydraulically balanced cartridge seal built for high-pressure, high-torque, and viscous services. Its heavy-duty construction helps limit face heat and supports reliable performance in crude oil and other moderately lubricating applications.
PPC PUDKW Single Cartridge Seal
A balanced mechanical seal with large internal components, a non-clogging single spring, and an integral pumping ring for API Plan 23 systems. It is designed for demanding midstream, refining, and petrochemical services involving solids, paraffin, and other difficult process conditions.
682A Pusher Seals
API 682 Type A cartridge pusher seals designed for compatibility with API 610 pumps. Available in single, tandem, and double arrangements, the balanced design uses multiple springs and O-ring secondary seals for reliable performance in process applications.
API Seals
682A Pusher Seals
Balanced API 682 Type A cartridge pusher seals with multiple springs and O-ring secondary seals. Designed for API 610 pumps, they are available in single, tandem, double, and custom configurations.
682B Metal Bellows Seals
API 682 Type B cartridge seals featuring flexible metal bellows and static O-ring secondary seals. These balanced, non-pusher designs are available in single, tandem, and double arrangements for applications where bellows technology offers added performance.
682C High Temperature Metal Bellows Seal
High-temperature API 682 Type C cartridge seals with metal bellows and static graphite secondary seals. Compatible with API 610 pumps, they are available in all three API arrangements and can be engineered for temperatures beyond standard API limits.
Engineered Seal Systems
PPC Plan 53B
A pressurized barrier-fluid system that uses a bladder accumulator to maintain seal pressure without a continuous external source. Optional heat exchangers, instrumentation, and integrated hand pumps can be added to simplify operation and maintenance.
PPC Plan 74
An all-in-one panel that filters, monitors, and regulates barrier gas for double mechanical seals. Standard components are mounted on a stainless-steel panel, with custom configurations available for specific gas-seal applications.
PPC Plan 65A
A seal leakage monitoring system that routes leakage to a reservoir, measures the rate, and signals an alarm when excessive leakage occurs. Carbon steel, stainless-steel, level switch, and transmitter options are available.
PPC Seal Water Controller
A compact pressure-regulating and flow-metering system designed to reduce seal water consumption and improve mechanical seal reliability. Available options include multiple materials, flow ranges, gauges, alarms, and a built-in tube cleaner.
