High Precision Tungsten Carbide Mechanical Seal Ring Hydraulic Rings
Features of the carbon products for mechanical use
The carbon-graphite material for mechanical use is with excellent
self-lubrication; good resistance to chemical corrosion; relatively
high thermal conductivity and thermostability; sufficient
mechanical strength; and it is easy to be processed into all kinds
of geometrical shapes. It is widely used in various mechanical
equipment, such as: the equipped sealing elements of centrifugal
pump, immersible pump, chemical reaction kettle, water turbine, and
steam roster, etc; the piston ring, guide ring and lining equipped
on the compressor, oxygenerator and ammonia pump; shield electric
machine, submersible motor and the bearing of other mechanical
equipment and instruments, etc.
The precision seal-ring is made of high quality materials by an
advanced process with serveral patented technologies, have very
complicated shapes, high accuracy, stable mechanic properties, much
higher wear and corrosion resistance, and a service life of more
than twenty thousand hours in the normal case.
Applications
The cemented carbide seal-ring can be divided into both of the
kinetic seal-ring and static seal-ring, and constitutes mechanic
seal together with the spring, rubber seal-ring and steel jecket.
It will be used mainly for waste water pump, water discharge pump
for the mines, centrifugal pump, centrifuge, slag slurry pump and
slurry pump in the adverse working conditions of high speed
rotation, sand flush abrasion and corrosion. The seal-ring will be
installed on the pump body and rotating axle, and forms through the
end face of the kinetc and static ring a liquid or gas seal.

Production Process
FAQ
Q1: How long is your delivery period?
A1: It depends on specific conditions. However, it could be 10 to
15 days on average.
Q2: Do you offer samples?
A2: Yes, we do offer samples. However, buyers need to pay for the
freight charge. In addition, whether samples are free or not
depends on the quantity you buy.
Q3: How do you pack the products?
A3: In general, we use wood, plastic or carton boxes. We also put
some soft materials inside to prevent possible damage on products.
Q4: How much advance payment do I need to make?
A4: If the products you buy are in stock, you need to make full
payment; if the products are out of stock, you need to make about
50 percent of full payment and then we will start the production
process. However, you still need to pay the rest of charges before
we deliver the products.
Q5: What kinds of payment do you accept?
A5: In addition to the patterns of payment shown above, you can
