FYD multistage pump

Product description:
The FYD series multistage submersible pump is a new and patented product which developed by feixiang industry for
transporting various sewages, oil, water .etc
Application:
Suitable for petrochemical industry, steel works, power plant, coal works, mine, chemical industry, medicine, building, and
drainage etc.
Working condition:
The medium temperature not over 200 ℃;
Liquid viscosity less 60cst.
Flow rate range: 5 m3/h to 300m3/h
Head range: 15m to 300m
Material:
Can made by different materials, such as cast steel, carbon steel ,stainless steel, Hartz alloy, according to different
condition.
Advantages:
1) High Efficiency Non-block up
The uniquely designed single, double-
passageway impeller, opening model, double leaf model impeller is high
effective without block-up, the pump casing etc. flow-through parts optimized designed for completing with the impeller
can be selected with their materials and models upon the transported media and can be made sure of the excellent
hydraulic performance and working life in the transportation of the media containing suspended grains and long fibres,
corrosive and abrasive. The great is wide and smooth and is suitable to transport the solid grain of a diameter about 50%
of the pump aperture.
The motor is not placed under water and the cable as well. Able to transport and suck the sewage of a temperature 200 ℃
and below, ultimately satisfying the applicable occasion or the requirements of use of dirty and oil resistance, wear ability
and with a higher temperature.
2) Easy use, long durability
The impeller is submerged in water and easy to start.
An automatic liquid-level control cabinet can be fitted with if so required by users so as to get the liquid-level to control the
pump's starting and stopping, without need of a special person to look after.Soild maintenance-free design, good rigidity of
the pump shaft and fully-closed roller bearing of a famous brand. The pre-injected high-temperature withstanding
lubricating grease makes no injection necessary during use. Stable running and
Low noise. Both bearing and pump's main shaft system are completely isolated by the shaft seal system and cannot
contact with the transported medium so as to ensure the designed running life of the bearing.
Double mechanical seals in series are used as the mechanical seal to provide a double protection and the frictional
secondary one is a spiral seal made of anti-corrosive sintered tungsten carbide or silicon carbide and of a special
structure and can thus be ensured to continuously run without leakage.
O -seal ring is used as the static seal, it settles the problem of leakage and greatly enhances the pump's life.
3) Stable, durable without vibration
The pump is vertically structured, the drive unit(motor stand, clutch, drive shaft, connecting stand, bearing)is modular
designed and can be superposed at will along with the variation of the under-water depth. Both pump casing and impeller
can be placed under liquid by 0.5-10m and the motor above the liquid surface, then, via connection with the drive unit,
directly drives the nonblack impeller to stably run without vibration. At the pump's inlet a suck-in barrel is set, its exquisite
design makes the sucked liquid's level as deep as possible e, without block up and with a good anti-twine
sewage-removal property.
