The Style 57 design serves to keep the sealing faces in contact and positively transmits the drive evenly 360° around the full circumference of the rotary face. This is accomplished by the special spring design, which provides an interference fit. The compression spring is wound either right or left hand depending on shaft rotation.

Stationary design accommodates higher shaft-to-stuffing box misalignment. The stationary bellows design only flexes once during installation unlike a rotating design which flexes on every revolution. This reduces face movement and increases seal life.

These two single cartridge seals are engineered for the most demanding corrosive applications. By minimizing the number of troublesome O-rings and eliminating any media exposure to the sleeves and glands, we have produced two very cost effective solutions to industries’ toughest applications.

In highly corrosive conditions that require expensive upgrades to higher alloy metals like duplex stainless steel, Alloy 20, Hastelloy® C276, the PH seals are an ideal economical solution. Only the wetted parts need to be constructed of these alloys while the larger metal parts such as the gland and sleeve can be 316 stainless steel since they are located out of the product

API compliant with piloted gland to positively center seal assembly and metal-to-metal confined gland gasket which prevents blow out or extrusion of the gland packing

Multi-point injection feature available which ensures maximum uniformity of cooling around the entire circumference of the sealing faces, thus eliminating face distortion due to uneven cooling. Ideal for boiler feed and light flashing hydrocarbon services.

Conventional pump stuffing boxes were originally designed to accommodate packing materials. Over the years mechanical seals edged out packing as a preferred sealing method, however stuffing boxes essentially remained the same. This situation posed complications for the effective operation of mechanical seals including installation issues, potential damage from abrasive product, and poor dispersion of seal-generated heat.

The ANSI Standard ASME B73.1 Specifications for Horizontal End Suction Centrifugal Pumps for Chemical Process includes specifications to improve the reliability and safety of the B73.1 pump design. One major specification focuses on cylindrical (big bore) and self-venting (tapered bore) seal chambers. Both of these seal chamber designs address the issues that plagued conventional pump chambers by providing additional radial clearance for mechanical seal operation and for increased liquid circulation around the seal, enabling the seal to run cooler and longer.

Only two (2) static elastomers – eliminate seal failures caused by dynamic O-ring “hang up” and offers cost savings when upgrading to Perfluorelastomers

Cartridge seals are a modern alternative designed to eliminate common causes of component seal failure. Check pump unit for defects before installing a cartridge seal to avoid damage to seal parts.

Single cartridge or double cartridge seals are self-contained units comprised of a shaft sleeve, seal, and gland plate. Cartridge seals are fitted onto the pump shaft as a single unit with no further fitting or assembly required.

Mechanical shaft seals are the best way to seal a pump. Face seals prevent leakage better than packing and if selected properly will last longer. Mechanical seals used in clean well lubricated applications can last 20 years. Seals can be constructed in single or double configurations, allowing only a vapor to escape.

Cartridge mechanical seal construction is a proven reliability improvement. The seals are pre-assembled at the factory, pressure tested and shipped as a unit, leading to improved performance as errors due to incorrect installation are reduced. Cartridge construction eliminates the need to measure and set spring compression, and having a mechanical seal pre-assembled means that the seal faces are protected from damage during installation.

A single mechanical seal is a type of mechanical seal which consists of one primary seal and it seals from process to atmosphere.There is always some leakage either to atmosphere or into process depending on the process pressure.

-Found as Wet-running (liquid phase between sealing faces) on liquid pumps, Dry-running (gaseous phase between sealing faces) on blowers/compressors/mixers.

-Nearly always dry running contacting seal (mechanical seal face wear) for top mounted mixers. For side and bottom mounted (seal is submerged) a wet-running seal is normally specified.
