IH chemical centrifugal pumps 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.

IH chemical centrifugal pumps Design characteristics

IH chemical centrifugal pumps 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.

IH chemical centrifugal pumps 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 IH chemical centrifugal pumps
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.
