I. General
description
The HIF fluoroplastic lining steel chemical
pump is a horizontal-type single stage
single suction overhung volute pump, whose
dimension is in accordance with the standard
of DIN2456/IS02858. The HIF pump may be used
to convey various corrosive liquors. It can
be widely used in the industries such as
chemical industry, metallurgy, power, paper
manufacture, seawater desalinization, food,
and pharmaceuticals industry. The pump can
also be used in the acidwashing, and paint
spraying processes in the automobile
manufacturing industry, in the electrolyte
convey process in the non-ferrous metal
metallurgy industry, and in the chlorine
water and waste water treatment, acid
feeding and chlorine drying processes in the
ion-exchange membrane caustic soda preparing
project.
The pump has the following characteristics:
|
Flow (Q) |
3．6～400m3/h |
|
Delivery lift (H) |
5～80m |
|
Working pressure (P)
|
1.6Mpa |
|
Working temperature (T)
|
-60℃～150℃ |
The features
of the pump design:
The outline and installation dimensions and
the basement are all in accordance with the
international standards, which enable our
product to substitute for the imported
pumps.
The inlet and outlet of the pump share the
same axial line, which will facilitate the
system design and pipe connection.
The bearing bracket, shaft, blade wheel and
the pump cover are assembled together, so
the pump needn’t be detached from the
pipelines during maintenance. If the
intermediate lengthened coupling is
available, even the motor needn’t be
detached from the pipelines either.
The bearing bracket and the basement should
perform anticorrosive protection, and the
working medium will not corrode the bearing
bracket and the basement in case of the
leakage of pump and pipeline. Hence the
service lives of the bearing bracket and the
basement are prolonged, so does the integral
service life of the pump.
The pressure applied on the shaft seal can
be compensated by the auxiliary blade, the
blade wheel balance hole or the auxiliary
blade wheel. The shaft seal is filled with
soft packing. Many seal types such as
single-end, or double-end mechanical seal,
and the combination seal.
The endurable rolling bearing and proper
shaft diameter ( Its shaft diameter is
5～10mm larger than that of the IHF pump with
the same specification) guarantee that the
set of shaft has enough strength and
rigidity, and consequently the pump can run
steadily. The pump bodies with certain
specifications are twin-volute style, which
enjoy balanced radial force to ensure the
steady operation of the pump.
The conveying medium and flow parts
The mineral acids such as the sulfuric acid,
nitric acid, hydrochloric acid, phosphoric
acid, and aqua regia and some organic acids
with different temperature and
concentration.
The alkaline solutions such as sodium
hydroxide and sodium phosphate with
different temperature and concentration.
Various saline solutions.
Various strongly corrosion media such as the
strong oxidants, organic solvents, and
reducers.
The materials of the pump flow parts:
The material of the pump body and pump cover
is steel with roller coating of F40. F40 can
bind the steel tightly and will not scour.
It can resist high-temperature and form a
smooth surface. So it is quite suitable for
manufacturing the lining of the pump. The
blade wheel is made by die pressing with F46
and PFA, which ensure that it possesses high
strength and anticorrosion performance.The
pump is a superior anticorrosion product
with advanced technology and high
performance. |
