API 610 - prescribes specific Design Features and Materials for Mechanical Seals. Materials - Metal parts (except multiple springs):

AISI 316 or equivalent - Multiple springs: Hastelloy C - Metal bellows: corrosion-proof material (max. corrosion wear 51μm p.a.) - Seal faces/ stationary seats: solid; no sprayed coating

API 682 - "Sealing Systems for Centrifugal Pumps" refers to Pumps used in Refineries/ Petrochemical Industry (Hydrocarbon-Processing Industries).

API 682 specifies Cartridge (Cartridge Preassembled) Mechanical Seals, as well as Dynamic Test Runs for all types of Mechanical Seals and arrangements with defined conditions.

API 682 requires continuous operation of at least 3 years, increased safety of operation and simplified maintenance. Arrangement and types of Seals: Arrangement 1: single Seal
Arrangement 2: double Seal without pressurization Arrangement 3: double Seal with pressurization

Type A: O-ring Seal/group springbacking

Type B: Seal with metal bellows, with O-ring secondary Seals

Type C: Seal with metal bellows, with graphite secondary Seals

Type SD: special Sealing design

Partial and Critical API Plans for various Circulation Systems - The most widely used API plans (610/682): API plan 01: Inherent product circulation from pump pressure connection to Mechanical Seal

API plan 01:
Inherent product circulation from pump pressure connection to Mechanical Seal
API plan 11:
Inherent product circulation from pressure
connection via orifice to Mechanical Seal
API plan 32:
Auxiliary flushing/ auxiliary injection with pure
liquid to Mechanical Seal
API plan 52:
pressureless, circulating quench - external vessel
(thermosiphon and/or forced circulation); tandem
Mechanical Seal
API plan 53:
pressure superimposed, circulating quench -
external vessel (thermosiphon and/ or forced
circulation), back-to-back arrangement
API plan 62:
external quench (steam, gas, water)

As Per API Plan Design Standards, we Design, Engineer, Procure, Manufacture, Test and Supply:
1. Unbalanced Seals & Balanced Seals
2. Single Spring Seals & Multiple Spring Seals
3. Pusher Type Seals & Non-Pusher Type Seals
4. Flexible Rotors & Flexible Stators
5. Face on Rotor & Face on Stator
In Pusher Type Seals with O – Ring; V – Ring; Wedge Rings and in Non-Pusher Type Seals –
Bellows Seals with Metal; Elastomers; TFE; TTE; Etc.,
Pusher Seals Incorporate Secondary Seals, called the Dynamic Gasket, which moves axially along a shaft or sleeve to maintain contact at the Seal Faces to compensate for the Seal Face Wear and for any Seal wobble due to misalignment.

Pusher Seals are relatively cheaper and techno-commercially more viable and wide rage of Sizes ideally suitable for most popular Rotary Equipments.
Designs are available for High Pressure Applications and for Low Quantity, High Technological Applications.

ROLON SEALS – Engineering and Technical Services gives new life to any Mechanical Seal that is no longer performing in the field. For several years ROLON SEALS has been a pioneer of the concept that customers can have all of their Mechanical Seals repaired in one location regardless of the original manufacturer. During all these years ROLON SEALS have refurbished hundreds of Mechanical Seals originally produced by other manufactures to their original specifications. Because we maintain an extensive library of manufacturers' design specifications we are the best at what we do, and do more of it than anyone else in the business. Utilizing the latest and up-to-date Seal design and engineering developments for our own line of Seals, we are often called upon by customers to evaluate other manufacturer's Seal designs to develop design modifications and enhancements that provide performance that is superior to the original.
ROLON SEALS Mechanical Shaft Seal's Quality Control Process produces a precision Mechanical Seal that which is tested and will provide safe and reliable performance. If you depend on Seals to deliver your products, you can depend on ROLON SEALS to deliver your Seals. Our experienced, skilled technicians use only premium materials and operate within a strict set of manufacturing procedures. The end result is a high quality product that meets or exceeds the specifications of the original manufacturer.
ROLON SEALS initiated in 1999 with an aim to specialize in Refurbishment, Retrofitting and Alternative / Substitution Solutions Service Provider of World Renowned Mechanical Seals Manufacturers like Eagle, Burgmann, Flowserve, Etc., and continuing to be an optimized
refurbishment and alternative / substitution solution provider with a motive to be a customer orientated corporation. During initial stages the complexity of refurbishment services and the optimized alternative / substitution solution providing has made us to receive, evaluate, and repair Mechanical Seals in a timely and economical fashion. Once completed and the Seal is back in our customers hands it will perform just like it was new. Today, our services are extended and our technical expertise & experiences has made us to provide on-site solutions to the greater extent.
Mechanical Seals are often perceived as very simple pieces of Equipment. Though individually the parts of a Mechanical Seal are Simple; Springs, O-Rings, Set Screws, Rotary Faces, and Stationary Faces, Collectively Each Piece is carefully dimensioned and Engineered to work perfectly together. There are many facilities throughout the India that repair Mechanical Sealsbased solely on the principal that the individual parts are simple. The companies who realize the engineering behind these parts have only the confidence to replace broken parts with identical new parts. If the Seal is badly damaged they must call the original manufacturer for new parts or try and aphazardly
duplicate the damaged pieces. This takes time and costs money, the two things that will limit any company in this industry.
The companies that do not realize the engineering behind the Mechanical Seal have very little success in repairing the Seal properly and eventually very little success in this business. The staff at ROLON SEALS has the education and a combined more than 9 years experience in Mechanical Seal design and application. ROLON SEALS has the ability to recognize or even change existing Seal dimension so that they may be repaired properly, quickly and economically. Our ability to dimension and tolerance exact replacement parts will allow us to buy these parts from a material vendor at a lower cost than others would have to pay the original Seal manufacturer. If the Sealsneed to be replaced ROLON SEALS can replace the Seal with an exact refurbished duplicate or one of many new Seals that will work equally as well in the customer's application ROLON SEALS utilizes a wealth of engineering knowledge coupled with a complete understanding of the multitude of Seal designs on the market today to give our customers the confidence of knowing that their Seals are repaired properly every time. We can handle the smallest single rubber bellows component Seals, to the very complex double dry running mixer Seals with bearings. ROLON SEALS has all of the tools to handle any Mechanical Seal repair
requirement. ROLON SEALS will be one of, if not they only, Seal repair company which has the technology to design and manufacture new Seals but has its focus only on repairing them.
