single cartridge mechanical seal quotation

Flexaseal offers a wide variety of single cartridge mechanical seals, each designed as a reliable solution for the toughest applications. Our single cartridge seals are easy to install and minimize the number of moving parts that can lead to equipment failure. Specially designed single cartridge seals are also available for highly corrosive or high-temperature environments. Cost-effective upgrades are available when circulation, vent, & drain glands are required.

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

"Single Cartridge Mechanical Seals" are used where there is corrosion and erosion in the seal media. This seal have good demand in sealing of rotation equipments. Single Cartridge seal are special purpose multi spring balance mechanical seals designees for use in abrasive or solid media.

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.
