Product Detailed Description

YL 2100, AKA U4901 or INT, Mechanical Seal for Centrifugal/Vacuum Pumps, Submerged Motors, Compressors, and Decelerators

Structural Features: single end, balanced, independent direction of rotation, rubber bellow, bellow transmission mechanical seal. This component seal has a compact structure and good compatibility and it is easy to install. The bellow and the spring provide pressure compensation to the sealing faces. The rubber bellow design can prevent radial run-out so that the floatability of the rotary ring is increased.

Industrial Standards: DIN24250, ISO3069, GB6556, EN12756

Scopes of Application: mainly used in centrifugal pumps, vacuum pumps, submerged motors, compressors, agitation equipment and decelerators for sewage treatment, chemical engineering, pharmacy, paper making and food processing. This component can work as an alternative to the similar product of John Crane.

Preperation:
1. Shaft Outside Diameter is within tolerance +-0.05mm
2. Shaft run out <0.1mm
3. Shaf end float <0.13mm
4, No sharp edges on the shaft over the o ring
Note:
During the installation,don't scratch or damage the o ring.lf anything is damaged,please contactwith Us to replace a new one.
Installation in strucstions:
1. The full set of cartridge seal is cleaned and exactly passed leakage examine before sale.Inorder to avoid damage,don't disassemble and clean the parts again before fixing.

2 The fitting allowance between the seal and shaft is dl h6 0.8,and there should be leading-inedge at the end of shaft.The outside diameter of shaft at the position of screw should be 01 0.2mm smaller,resisting the screw over-tighten.Lubricate the shaft with oil

3. Place the cartridge seal into the pump chamber,then:
A: Tighter four screw bolts of flanges,ensuring the medium leading in hole"G"at the top Position
B : Tighter four set screws and position the shaft sleeve on the shaft.
C: Remove four gauge plates.Please keep them and they wil be used in future installation and
disassemble.
D: Connect the medium lead_in pipe with hole"G"in order to flush away the friction heat and
flushing the seal chamber when pump running.
Note:
ter complete the installation,turning the shaft by hand to check for the rotationi he shat could not rotate smoothily,seal had been improperly installed.
