IHG vertical chemical pipeline pump

Product Details

1、 Product Overview
IHG type vertical single-stage single suction chemical pump has excellent performance, high reliability, long service life, reasonable structure, and beautiful appearance.

2、 Purpose:
IHG type vertical single-stage single suction chemical pump is used for conveying liquids that do not contain solid particles, are corrosive, and have a viscosity similar to water. It is suitable for departments such as petroleum, chemical, metallurgical, power, papermaking, and food and pharmaceutical industries, with a temperature range of -20 ℃ to+105 ℃.

3、 Working conditions:
1. The suction pressure is ≤ 1.6MPa, or the working pressure of the pump system is ≤ 1.6MPa, that is, the pump suction inlet pressure+pump head is ≤ 1.6MPa, and the pump static pressure test pressure is 2.5MPa. Please specify the system working pressure when ordering. When the working pressure of the pump system is greater than 1.6MPa, it should be separately stated when ordering, so that the overcurrent and connection parts of the pump can be made of cast steel materials during manufacturing.
2. Environmental temperature<40 ℃, relative humidity<95%.
3. The volume content of solid particles in the conveyed medium shall not exceed 0.1% of the unit volume, and the particle size shall be less than 0.2mm.
Note: If the medium used is with small particles, please indicate it when ordering so that the manufacturer can use wear-resistant mechanical seals.

4、 Product features:
Smooth operation: The absolute concentricity of the pump shaft and excellent dynamic and static balance of the impeller ensure smooth operation without any vibration.
Drip proof: Hard alloy seals made of different materials ensure that there is no leakage during the transportation of different media.
Low noise: The water pump supported by two low-noise bearings runs smoothly, with almost no noise except for weak motor noise.
Low failure rate: The structure is simple and reasonable, and the key parts are of world-class quality; Matching, the whole machine's fault free working time is greatly improved.
Easy maintenance: Replacing seals and bearings is simple and convenient.
More land saving: The exit can be arranged in three directions: left, right, and up, which is convenient for pipeline layout and installation, saving space.
