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.

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

Mechanical seals are available in a variety of sizes, including 0 or 0.5 or 1 or 1.125 or 1.5 or 1.625 or 1.75 or 2.375 or 4 or 11 or 15 or 19 or 22 or 23 or 28 mm or 32 mm or 38 mm or 42 or 50 mm or 60 mm or 65 mm or 72 or 73 or 76 or 185 or 225 or 275. Selecting the right size mechanical seal is important for optimal performance and reliability. A mechanical seal with the correct shaft size ensures an accurate and secure fit on the pump shaft, distributing pressure correctly and preventing leakage.

Double cartridge mechanical seals have axial double-face seals and radial double-face seals. The radial double cartridge shaft seal’s structure is more compact than the axial double cartridge seal. Double cartridge pump seal is widely used in the media which is poor Lubricated, toxic, flammable, explosive, volatile, containing abrasive and gas etc.

The pre-installation of the dual cartridge mechanical seal is simple and easy to operate. It simplifies the process of measurement and adjustment, and has the characteristics of simple installation and strong interchangeability. The damage to the sealing element caused by the mechanical seal installation is avoided and the maintenance cost is reduced. With high quality imported special ceramics, corrosion resistant graphite, sintered carbide and other sealing materials, the life of the mechanical seal is improved.

Balanced seal ring design, can withstand higher pressure fluctuations of the medium; (3) stationary ring automatic compensation mechanism. Can overcome the influence of the angular offset of the end face and compensate the non-perpendicularity of the end face and the shaft;

Cartridge mechanical seals are widely used in all sectors of enterprises. Such as water pump plant, printing and dyeing machinery plant, paper mill, power plant, chemical plant, pharmaceutical shipyard and sewage treatment plant, and are widely used in hospitals, agriculture, equipment cooling, leather making industry, heavy machinery and so on.

The principle of the double cartridge mechanical seal is basically the same as Single cartridge mechanical seal. Both of them are constituted by the seal face (friction pair) perpendicular to the rotation axis, worked as Fluid leakage device based on the function of the fluid pressure and the compensation mechanism and the auxiliary seal. Double cartridge shaft seal has two face seals, if the primary seal fails, the secondary seal can still be sealed to prevent leakage.

The use of dual mechanical seal allows the cleaning fluid to be held between groups of surfaces. This allows the sealing surface can only see a clean lubricating fluid, greatly extending the life of the seal.

General dual mechanical seals are required for sealing liquid system. Sealing fluid is introduced into the sealed chamber for blocking, lubrication and cooling, and is mostly used for circulating cooling. Sealing fluid can not only wash the friction pair to improve the working environment of the mechanical seal, but also as an important sealing surface failure is an important means of detection.

A single cartridge type mechanical seal consists of two very flat surfaces that are pressed together by a spring and slide against each other. The single mechanical seal is a mechanical seal composed of 1 set of seal face. the sealing structure is simple, easy to manufacture and install features. Generally, cartridge type mechanical seal is used for the medium with good lubricity and allows a slight leakage. Single cartridge seals are one of the most commonly used centrifugal pump seal types. Single cartridge pump seals do not work well when the media is the toxic, flammable, explosive and strict requirement of leakage.

Mechanical seals tend to leak a vapor from the high-pressure side to the low-pressure side. This fluid lubricates the seal faces and absorbs the heat generated from the associated friction, which crosses the seal faces as a liquid and vaporizes into the atmosphere. So, it’s common practice to use a single cartridge mechanical seal if the pumped product poses little to no risk to the environment.

When a single cartridge seals used in the oil-filled motor, it is not only necessary to prevent the machine outside the impurities, sand and water to enter, but also to prevent the leakage of oil within the machine, so sealing requirements is higher, sealing ring material requirements need to be good, its sealing face material  is made of tungsten carbide or silicon carbide. If it is installed on the shaft of the water-filled motor shaft, it only requires sand control. The sealing ring can be made of alumina ceramic, silicon nitride or other harder materials, so the cost is relatively low.

The installation error rate of the Common non-cartridge mechanical sea is higher than the cartridge mechanical seal. Therefore, use cartridge shaft seal can greatly reduce the occurrence of mechanical seal failure.

Since the cartridge mechanical seal does not require any adjustment of the mechanical seal by the installer (such as spring, sealing surface, etc.), only the bolts need to be tightened, which greatly improves the reliability of the mechanical seal installation.
