Available in diverse combinations of materials and different
diameters: 12, 16, 22, 28, 33, etc. Also mechanical seals for
Sarlin®. Division of waster pumps. Available in various materials:
silicon-graphite carbide, silicon carbide-silicon carbide; combined
with EPDM and FKM elastomers.
2. Mechanical seals are available for different references
Gorman-Rupp® pumps. Special models for the transfer of clean water,
sewage, oil industry, agriculture and others.
GRN-38'1
3. Mechanical seals for Fristam® pumps. Wide range of models and
materials in the most standard diameters: 22,30 and 35 mm.
Different assembly possibilities for the most well-known pump
models: FP, FL and FT.
4. Broad range of mechanical seals compatible with Flygt® and

ZMA, ZMB, ZMD, ZMS, ZMH, ZMK. Rosista® and Pasilac®, W and W+. Some
designs with wave spring like the special seals for APV Howard®
pumps and Crepaco Clean Line®. All of them have been manufactured
in materials suitable for working with fluids such as juices, milk
and drinks in general.
9. Allweiler, Simple design of mechanical seals simple but with
special measures for this type of pump.
10. Mechanical seals for ABS® submergible pumps specific wastewater
treatment. Different models of mechanical seal available: oil
chamber mechanical seal and water mechanical seal.
Fixing and Applying Directions of Mechanical Seals
1. Select Appropriate mechanical seal to match the materials
according to work conditions and host machine equipment.
2. The radial acting deviation for the shaft(shaft sleeve) of the
installed mechanical seal shall be 0.04mm by maximum
while the axial movement value of the rotor shall be no more than
0.1mm.
3. The seal cover (or shaft cover) of the stationary ring of the
installed mechanical seals,the vertical degree of the seal
face should be 0.04mm by maximum.
4. When installing the mechanical seals,the shaft(shaft
sleeve),seal chamber,seal face as well as the mechanical seal
must be cleaned in order to keep from any medium to sealing part.
5. When conveying medium of over high or low temperature,with
medium which are easy catch fire,easy for explosion.
Related mechanical seal standards must be referred to take
appropriate measures such as quench,rinsing,coolong and
filtrating.
6. Appropricate lubrication must be choosen when mechanical seal is
installed.The installment size of the mechanical
seal must be guaranteed to the installment instruction.
7. Before the machine starts running,the hermetic compartment shall
be full of medium and well lubricated.Dry friction
which may lead to the damage of the air-tightness is strict
forbidden.
