If you don’t see the mechanical seal pump that fits your needs, our specialized team will create custom seals to meet your application. Our products are expertly manufactured from high-quality materials, ensuring that your seal will last for years to come. Check out our selection today!

Modern pumps, compressors, mixers, agitators and other rotary shaft equipment are assembled using either compression pump packing or mechanical seals to minimize emissions and fluid.

Compression pump packing controls leakage whereas mechanical seals will tend to stop any visible leakage all together, keeping work environment clean and hazard free.

Compared to compression packing the initial cost of a mechanical seal is high, however overtime, the associated cost accrued by using compression packing, for example power consumption, maintenance and downtime, could be far in excess of the initial cost of a mechanical seal, which works unattended for a long time.

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.

If you have any query around how to install a single mechanical seal for agitators or mixers or have some concerns around the seal failures, why not contact one of our mechanical seal specialists below to discuss it in more detail and find out how we can help solve your issues and get your process back up and running reliably again.

We recognize and understand the vital role of john crane type 1 mechanical seal in their application. With purposes including securely fastening components within systems, and contaminants prevention such as gases and liquids from navigating through enclosed and sealed areas. That is why we offer wholesale john crane type 1 mechanical seal in different variations and diversities to ensure the integrity and efficiency of systems they will be applied to will function successfully and optimally. The different seals" types available include static that does not move along with other seals and dynamic seals that move collaboratively.

Depending on the industry and selected purpose, we consider john crane type 1 mechanical seal requirements. Requirements are like pressure, that is pressure changes, to ensure they can withstand and do not deform by the sealed fluid, the load and how it can withstand deflection, dynamics such as the alignment and vibration, and temperature covering the environmental conditions and the heating arising from the friction of the seal operation and fluid movement.

The seals are either bolts, nuts, or washers. Seal bots are commonly used because of their benefits in being reusable, preventing fluids and contaminants from escaping even under high pressure. Nuts are essential on temperature withstanding and compatibility with screws, studs, and bolts, in addition to, easy installation. Moreover, washers can withstand high pressures and are compatible with other seals.

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

Mechanical seals are devices that seal machines between rotating parts (shafts) and stationary parts (pump housing) and are an integral part to the pump. Their main job is to prevent the pumped product from leaking into the environment and are manufactured as single or double seals. What"s the difference between the two?

A single mechanical seal consists of two very flat surfaces that are pressed together by a spring and slide against each other. Between these two surfaces is a fluid film generated by the pumped product. This fluid film prevents the mechanical seal from touching the stationary ring. An absence of this fluid film (dry running of the pump) results in frictional heat and ultimate destruction of the mechanical seal.

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 mechanical seal if the pumped product poses little to no risk to the environment.

A double mechanical seal consists of two seals arranged in a series. The inboard, or “primary seal” keeps the product contained within the pump housing. The outboard, or “secondary seal” prevents the flush liquid from leaking into the atmosphere.

Two rotating seal rings are arranged facing away from each other. The lubricating film is generated by the barrier fluid. This arrangement is commonly found in the chemical industry. In case of leakage, the barrier liquid penetrates the product.

The spring loaded rotary seal faces are arranged face to face and slide from the opposite direction to one or two stationary seal parts. This is a popular choice for the food industry, particularly for products which tend to stick. In case of leakage, the barrier liquid penetrates the product. If the product is considered “hot”, the barrier liquid acts as a cooling agent for the mechanical seal.
