Product Description

Cartridge Mechanical Seal ES ED ESH EDH EDP BC Balanced Single Double for Food and Pharmaceutical Water Pump Seals
 

Bestseal is a leading company specialized in mechanical seals of the highest quality for a wide range of industries and applications.
The company is committed to the research of best raw materials to always improve industrial mechanical seals characteristics and offer high performance in each sector.

Bestseal mechanical seals for pumps offer a wide range of advantages such as:

ES
balanced single cartridge seal

Bestseal ES is a balanced single mechanical seal with a unique and modern design. The springs are not placed directly behind the stationary face, this being the most common competitor solution, but have been located on a larger diameter further away from the critical O-ring and seal face gap in order to reduce risk for clogging. Due to the relocation of the springs, more robust springs may be used enabling to change from compression to tension springs. The robust tension spring design gives the seal better performance since it is more difficult for particles and fibers from the product to reach and clog up the springs. Additionally, the relatively long springs with larger wire diameter increase the axial and radial movement capabilities of the seal.

First-class materials from carefully selected suppliers ensure optimized performance at minimized built-in dimensions.

Hygienic solutions
Smooth surfaces without cavities or closed spaces make the seal suitable for food and drug application. If required the gasket may be replaced with O-rings in execution according to EHEDG to achieve a hygienic designed seal suitable for CIP (Cleaning in Place).

H4 design
The rotating sealing face on the product side has the new "H4-design". This means that the seal is O- ring mounted and the outer diameter of the seal face is the same as of the holder. This prevents the forming of turbulent flows, which cause heavy wear in abrasive liquids.

Advantageous built-in dimensions
Fits in most standard pump stuffing boxes.

Optional additional flange for flushing
The seal may be equipped with an extra flange when flushing into the media is needed. The standard design is without flange since the chamber with a small gap given by the flushing flange may encourage material build-up if flush is not connected.

Spring package located on the outside of the flange
This design is better protected against fiber and particle build-up, which eventually causes clogged- up springs.

Patented tension springs
Allow for an excellent axial movement of ± 2,0 mm.
Patent No: 9803436-6

Excellent angular movement capabilities
Advantage when operating against closed valves, causing shaft bending.

ED
balanced double cartridge seal

Bestseal ED is a double balanced cartridge seal maintaining sealing performance even during sudden pressure drops on the product side and/or the secondary side.

The design of the seal is robust and rigid but at the same time flexible, with excellent radial and axial movement capabilities.

The springs are located outside both the product and the flush minimizing risk for clogging.

Excellent axial movement
The seal can move ± 2,0 mm independent of the compression of the springs. The seal follows the movement of the shaft without influencing the compression of the springs. This feature is essential when sealing equipment with flexible bearing units.

Patented protected spring package
The springs are located outside both the product and the flush. Minimizing the risk for clogging, which is one of the most common causes for seal failure. Patent No: 900912-2

Safe drive of rotating surface at the atmospheric side
The rotating face on the atmospheric side is driven by three big drive pins machined into the sealing face. The pins are not in contact with the quench liquid, eliminating the risk of them being blocked axially by residues from the quench.

Hygienic applications
Smooth surfaces without cavities or closed spaces make the seal suitable for food and drug applications. If required, the gasket may be replaced with O-rings according to EHEDG in order to achieve a hygienic designed seal suitable for CIP (Cleaning in Place).

H4 design
The rotating sealing face on the product side has the new "H4-design". This means that the seal face is O-ring mounted and the outer diameter of the seal face is the same as of the holder. This prevents the forming of turbulent flows, which cause heavy wear in abrasive liquids.

Axial cooling channels
Allow for installation of a double seal in applications with very limited space.

Excellent radial movement capabilities
Through a new design the seal is able to compensate for angular deviation without generating stresses over the seal faces, which may influence sealing performance. This feature minimizes the effects of excessive shaft bending during operation against closed valves.

ESH
single balance cartridge seal for food and pharmaceutical

This seal is suitable for food and pharmaceutical industries.The seal design and choice of engineering materials have been specifically chosen for optimized operation in demanding applications.

EDH
balanced double cartridge seal with hygienic design

Bestseal EDH is a balanced double cartridge seal with hygienic design in compliance with the EHEDG standard. The design makes the seal suitable for food & pharmaceutical industries. The choice of engineering materials have been specifically chosen to optimize operation in demanding applications.

EDP
balanced double cartridge seal with a special shaft sleeve

The Bestseal EDP is an ED seal equipped with a special shaft sleeve which creates a pumping effect. Combined with a thermosiphon tank it provides an ideal standalone solution for applications where seal water is not available.

BC
balanced double cartridge seal

The Bestseal BC-series is a new type of seal designed for various heavy duty applications where durability is key. This is a robust, reliable and cost effective seal suitable for standardization in larger process industries but also for customers with more limited amounts of equipment.
During the development of the BC-series the main focus has been on adaptability to different pressure and speed conditions, reliability and ease of installation. The BC is a double balanced seal that handles pressure drops on either product or barrier/buffer sides and effectively minimizes heat generation at the seal faces.

Designed to fit most standard equipment
Suitable for standardizing
Robust and durable design
Ability to handle pressure fluctuations
Easy to install

1 Excellent axial movement

The seal can move ± 2,0 mm independent of the compression of springs. The seal follows the movement of the shaft without influencing the compression of springs. This feature is essential when sealing equipment with flexible bearing units.

2 Spring package is kept clean by the flushing

The springs are located in the area circulation and the exchange of barrier fluid is the greatest. This eliminates the risk for clogged-up springs, which is one of the most common causes for seal failure.

3 Adaptable flushing connectivity

Four different ways to connect the flushing media to the flange. Axially, horizontally or a mix of both.
This feature facilitates the installation of the seal in confined spaces and allows for obstructing equipment to be bypassed.

4 Innovative inverted flange/cover design

The flange configuration with inboard cover. This reduces the cost of the seal by lowering the amount of expensive material potentially in contact with abrasive or corrosive media.

5 Clever double balancing

The seal is double balanced using a "floating" o-ring design. This enables the seal to handle sudden pressure variations. This also makes it possible to reduce heat generation.

6 Symmetric design optimized for standardization

The seal faces used on the product side can also be used on the atmospheric side. This allows for all internal parts to be used on both sides for high standardization purposes.
