HJ92N Medium stainless steel wave spring pump Mechnaical Seal

HJ92 stainless steel medium mechanical seal non-equilibrium

Single seal / Unbalanced /Independent of direction of rota.tion /Spring product protected / To DIN 24960*

Mechanical seals of the HJ92N series are designed for media con.taining solids or with high viscosity e. g. sugar, paper, sewage ancwaste water industry. The springs are product protected. There isno sticking or clogging making the design rugged and reliable.

An integral stationary seat lock is notneeded within the permissible low pressure range. For prolongedoperation under vacuum it is necessary to arrange for quenching onthe atmospheric side. Axial movemenl士0.5mm

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:

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.
