flowserve mechanical seal parts supplier

Siewert Equipment is the exclusive provider of Flowserve mechanical seals for Upstate, NY. Flowserve seals are the industry’s top choice for the most challenging environments. We offer a complete line of seals, including cartridge seals, dry-running seals, metal bellows, elastomeric bellows, mixer seals, split seals, and bearing protection devices.

Since 1959, Pioneer Equipment has served the Southwest United States with Flowserve mechanical seal solutions for pumps used in a wide range of commercial and industrial applications.

Based in Phoenix AZ, Pioneer Equipment, Inc. has stocking branch offices in three states and four metropolitan areas. For nearly sixty years, Pioneer Equipment has been a distributor and servicer of air compressors, pumping systems, and pumping system accessories. We carry a full range of Flowserve mechanical seal products and accessories at our branches in Phoenix and Tucson.

The Flowserve company was registered in 1997, having already 230 years of experience in the field of fluid flow control, and is today a world-renowned corporation (represented in more than 50 countries around the world). Sealing technologies are an effective direction of the brand. Creating reliable products, Flowserve supplies mechanical seals and sealing systems for a variety of equipment – pumps, compressors, agitators, steam turbines, etc.

Amechanical seal is the most common type of sealing component used on pumps in modern industry. Replacing out packing over the last 50 or so years, they have served to drastically reduce industry emissions, energy usage and downtime globally.

A mechanical seal for pumps can be subdivided into variable options depending on the type/specific application/design components/location and mechanical seal characteristics;

The major advantage of a cartridge seal over a component seal is ease of installation. Incorrect installation is a major cause of seal failure, cartridge seals remove many of the problems associated with seal change-out in the field.

Slurry Seal – mechanical seal engineered to cope with a heavy slurry process – i.e. abrasive, corrosive and viscous. Can handle up to 60% slurrys by weight.

A Pusher Seal is where there is a spring element in the seal (used to maintain contact of the seal faces). Spring types include Belleville, multi-spring, etc. This type of seal requires a dynamic secondary seal.

A gas seal is a double seal where the barrier fluid is a gas – in pumps, this is usually a gas lift-off seal. In a gas lift-off seal the faces are not in contact while the machine is running. They are separated by a thin gas film (flow). If operated correctly they have very low wear.

The above seal types can be combined (though it is not always best to do so i.e. a component gas lift off seal would require very close collaboration between the machine and seal manufacturers to achieve a reliable installation).

There are many other options for mechanical seals, if you have any technical queries on other combinations not listed above,  just contact one of our Mechanical Seal Specialists who will gladly discuss your application.

A mechanical seal flush is a piping set-up on a pump and seal assembly where a flow is induced in the seal chamber in order to improve MTBF of the mechanical seal. It is used to improve cooling, heating, remove solids and increase pressure (in combination with a neck or throat bush).

A mechanical seal quench is a piping set-up where a fluid is piped over the atmospheric side of a seal. It is generally used to prevent precipitation or crystallisation of a product or in some cases to aid cooling.

High Slurry process using Flowserve’s UNCD ® – Ultrananocrystalline diamond  seal face technology. Flowserve UNCD ® coatings offer material properties and performance advancement over all other seal face materials.

Slurry seal design expertise applications which previously required double mechanical seals can now be reliably run by using single mechanical seals, saving costs of barrier fluid systems, the costs of the barrier fluid itself & the associated running costs. This reduces energy usage & carbon footprint.

If you have a technical query around the installation of mechanical seals for pumps or have some concerns around seal failures, why not contact one of our seal specialists below to discuss it in more detail and find out how we can help solve your issues and get your process running again.

PusherPusher seals incorporate secondary seals, called the dynamic gasket, that are pushed by springs axially along the shaft or sleeve to compensate for seal face wear or wobble due to misalignment.

Bellows seals are very similar , but they use a welded metal bellows to achieve flexibility in the design. A bellows seal avoids the use of a "dynamic" gasket which can be very beneficial in specific applications.

Whether you have a slury liquid that requires economic value, standard application, or extreme service seals, Flowserve is uniquely positioned to provide solutions for virtually all slurry services.

Gas seal technology and gas seal operation depends on aerostatic and aerodynamic forces. Careful design keeps the two faces separated by a gas film. Aerodynamic forces are created by the presence of a "pattern" on one of the faces.

CompressorCentrifugal compressors and other turbomachinery are critical to the operation of a process plant. Selecting a manufacturer with well proven state-of-the-art low friction dry gas seals who can offer full field maintenance support is very important.

OEM & Special DutyOriginal Equipment Manufacturers (OEM"s) are very important for Flowserve FSD. Therefore Flowserve is committed to develop and supply designs for special equipment and for special duty requirements.

OutsideOutside mounted seals are used in strongly corrosive applications. This arrangement allows seal designs that have no metal parts in contact with the process liquid.

Standard cartridge seals such as the ISC seals are designed for general purpose applications on ANSI and DIN process pumps serving chemical processing, pulp and paper, oil and refining, food and beverage, water and wastewater, and other industries.

For optimum performance of mechanical seals, control over the sealing environment is very important. If the seal is kept clean and well lubricated by the product or barrier it will deliver years of reliable service.
