- Interchangeable stuffing boxes come equipped with 303 stainless steel parts and Buna-N® elastomers for a longer pump life.
- Mechanical seals are included in standard constructions and include carbon against ceramic face for optimal hot water performance.
- Grease lubrication bearings are conveniently located for quick access and outfitted with oil seals and non-sparking neoprene rotating slingers to protect bearings during operation and washdowns.
- High-load bearings provide a minimum of 50,000 hours of performance at maximum load thanks to double-row thrust ball bearings and arms that help eliminate misalignment.
- Left-hand rotation is available with standard parts.
- Performance certification with positive suction pressure or suction lift is available on each pump for customer approval. All pumps are hydrostatically tested for optimal performance.
