Products overview
IH chemical centrifugal pumps are single-stage, single-suction and
cantilevered centrifugal pumps, manufactured according to
international standard combining with non-metallic process design.
IH is a energy-efficient production instead of F corrosion
resistant pump. IH chemical centrifugal pump is suitable to
transport liquid without solid particle, corrosive and viscosity
similar to water. The medium temperature is between -20 Celsius
degree and 105 Celsius degree, and when convey high temperature
medium, there should be cooling measurements. The IH pumps are
widely used in chemical, petroleum, electric power, metallurgical,
paper, pharmaceutical, food industry etc. with a lot of advantages
such as corrosion resistance, abrasion resistance, high temperature
resistance, high mechanical strength, stable operation, advanced
and rational structure, strict and reliable seal performance,
convenient dismantling and repair, long service life etc.
IH chemical centrifugal have 33 basic models, and about 22 models
are double speed(2900r/min 1450r/min). After cutting and
deformation of the impeller diameter of the A/B models, the total
of the productions reaches 112 specifications.

Design characteristics
Pump composition
IH series chemical centrifugal pumps are joint-design products by
pump industry nationwide according to ISO international standard.
The main parts are pump casing, impeller, seal ring, impeller nuts,
pump cover, seal parts, middle support, shaft, suspension parts and
so on.
Pump structure
Pump cover is fixed on the middle support by seam, and clamped by
the connection of the pump casing and seam in the middle support.
The pump casing is axial suction, radial discharge and supported by
feet type, and can be fixed on the base directly. Suspension parts
can be fixed in the middle support by seam and supported on the
base by suspension bracket. The extension coupling is designed for
convenient dismantlement. When the pump needs check and repair,
only the middle connection parts of the extension coupling need to
be dismantled, that is quit the rotor parts for check and repair.
Connection pipes of the inlet and outlet, pump casing and the motor
are not necessary to be dismantled. That is the universal structure
form in the world.
The rotational direction of the pump
The pump is driven directly by motor from extension coupling. View
from motor, it makes clockwise rotation.
Shaft seal type of the pump
The shaft seal adopts packing seal or mechanical seal, which can be
selected according to clients’ requirements. Meanwhile, it’s
allowable to adopt sealing cavity size according to ISO3069 as
required and other shaft seal type.
Packing seal: There’s stuffing box in the pump cover; adopt soft
packing seal; Water with certain pressure can be convey into the
stuffing box for sealing, cooling, lubricating and cleaning.
Mechanical seal: Single-face mechanical seal and double-face
mechanical seal; Water with certain pressure can be conveyed into
the sealing cavity for flushing, rubbing the face and cooling as
well.
