Mechanical seal systems are also known as mechanical seal auxiliary systems or mechanical seal flushing, cooling and piping systems.

In order to make the mechanical seal work reliably and stably, it is important to choose the appropriate auxiliary system besides the seal itself should be designed reasonably, the material should be selected properly and the manufacturing installation is good.

Mechanical seal systems include basic components and the following systems: pressure control system, temperature system, fluid replacement system and impurity removal system.

YUEMI is a professional manufacturer of mechanical seals and OEM pump seals since 1996.

Conform to the DIN24960 and GB6556 standards.

Our seals are interchangeable with John Crane, AES, Flowserve, Fluiten, Roten, Sealtek etc.

If you want to know more about our seals, pls. send inquiry to me directly and I will recommend suitable seals to you.

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.
