Features mechanical seal es
Huhnseal 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 fom 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.
Operating range mechanical seal es
- Pmax = 25 bar
- Tmax = 100°C
- Vmax = 18 m/s (3600 rpm)
- Axial movement: ±2,0 mm
- Hygienic solutions mechanical seal es
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).
- Excellent angular movement capabilities seal es
Advantage when operating against closed valves, causing shaft bending.
- H4 design mechanical seal es
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 seal es
Fits in most standard pump stufﬁng boxes.
- Optional additional ﬂange for ﬂushing seal es
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 seal es
This design is better protected against ﬁber and particle build-up, which eventually causes clogged- up springs.
- Patented tension springs mechanical seal es
Allow for an excellent axial movement of ± 2,0 mm.
