Specifically designed for Heavy-Duty Slurry applications, where flush is undesirable or not possible.

Dynamic secondary seal is a clogging and wear-resistant rubber diaphragm.

Diaphragm is fully supported by a lubricating buffer medium for zero-pressure-related stress.

Buffer lubricant is factory filled and sealed for a complete life cycle of field service.

Dynamic o-ring, springs, and drive-lugs operate in a protected, clean, and lubed environment.

Speeds up to 5000 RPM.

Pressure to 30 bar, depending on size, sealed media, and operating conditions.

Pump-specific design for each application.
