HIH stainless steel chemical centrifugal pump

1. Five core features of the product

1. National standard standardized design with excellent overall performanceIndependently developed according to ISO2858, GB5662, DIN24256 international standards, with all technical indicators aligned against imported chemical pumps; The hydraulic components are optimized using CFD fluid mechanics simulation, featuring a wide flow channel, high operational efficiency, and excellent cavitation margin performance, making it a nationally promoted energy-saving industrial pump product.

2. Full stainless steel modular current-flow componentsThe pump body, impeller, and pump cover are all made of stainless steel precision casting, with a modular design with highly interchangeable components; High rigidity, erosion resistance, non-oxidation, resistant to corrosion from various weak acids, weak alkalis, and organic solvents, and long-term continuous operation is not easily rusted or damaged.

3. Multiple materials available, with built-in mechanical sealsStandard is an internally mounted single-face mechanical seal, with optional silicon carbide or cemented carbide for the sealing ring material as needed; Supports upgraded dual-face mechanical seals and external mechanical seals, suitable for media containing trace crystals, volatile, or toxic, preventing media leakage.

4. Post-pull no-disassembly pipeline maintenance structureInternational standard coaxial post-pull layout: when repairing or replacing seals, impellers, or bearing assemblies, there is no need to disassemble the inlet and outlet process pipelines; maintenance can be completed simply by pulling the internal rotating parts backward, greatly shortening downtime for maintenance.

5. Horizontal operation with low noise and smooth operation, strong versatilityHorizontal base vibration isolation layout ensures low vibration amplitude and low operating noise; Dimensions and flange standards can be directly interchanged with chemical centrifugal pumps of the same specifications on the market. Customers can replace or modify on site without changing piping, adapting to new and old production line upgrades.

Parameter remarks

The standard design pressure for the entire machine is 1.6MPa, with a suitable temperature range of -20°C~350°C; If the specific gravity of the conveyed medium exceeds 1.3g/cm³, advance notification must be given when ordering, and the custom increased power motor should be adapted to a high specific gravity load; The entire series can be optionally equipped with explosion-proof motors, dual-face mechanical seals, and external cooling and flushing pipelines as needed.

4. Applicable industries and corresponding working conditions scenarios

Petroleum and fine chemical industry

Conveying crude oil, various acid-base reaction fluids, and high-temperature organic solvents, high-power DN100/DN125 models paired with explosion-proof motors; The stainless steel current-flowing components are resistant to chemical corrosive media, the post-pull structure is adapted for large continuous reactor circulation, and the explosion-proof configuration eliminates the risk of fire from flammable and explosive media.

Electroplating, PCB circuit board industry

Conveying neutralizing acids, brightening additives, and weakly alkaline cleaning solutions, DN50/DN65 small to medium flow specifications; The stainless steel material prevents excessive metal ion precipitation, ensuring uniform coating on electroplated workpieces. The horizontal base is compatible with the filter unit for installation.

Pharmaceutical and API production workshops

Conveying sterile extraction solvents and weak acid intermediates, customized 304/316L stainless steel flow-through models; The runner is smooth, without dead corners, making it easy for CIP to clean online, and complies with pharmaceutical clean production standards.

Rare earth and mining and smelting industries

Conveying low-concentration acidic leachate and rare earth extraction agents, DN80/DN100 medium to high head models; The entire machine is highly rigid and resistant to trace solids in slurry, with a wide flow channel impeller that is not easily clogged, suitable for long-cycle continuous smelting production.

Environmentally friendly large-scale wastewater and exhaust gas tower equipment

Large-flow circulation transport of comprehensive acid-alkali wastewater and exhaust gas neutralizing spray chemicals for the plant, DN125/DN150/DN200 large-diameter models; High-flow capacity suitable for large integrated wastewater stations and multi-stage exhaust gas scrubbers, providing stable and continuous spraying of mixed chemicals.

Supporting equipment for scientific research and military industry

Various low-corrosion high-purity reagents and thermal conductive high-temperature oils are conveyed in a sealed way; low-flow DN50 specification offers optional explosion-proof and high-temperature resistant sealing kits; Standardized flanges can be flexibly adapted to complete laboratory reaction equipment.

5. Precautions for model selection and safe use

1. Specific gravity specification: Standard motors are only compatible with liquids with a specific gravity ≤ 1.3g/cm³. If the specific gravity of the chemical solution exceeds this value, the motor must be upgraded and increased at the time of order to avoid overload and motor burnout.

2. Medium particle restrictions: This machine is only suitable for small amounts of soft-crystalline corrosive liquids without solid particles. It is strictly forbidden to transport large amounts of hard slag or block-like crystalline media, as solid impurities will rapidly wear down mechanical seals and impellers.

3. Do not run idle: Before starting, the pump chamber must be filled with the transport medium. Without dry running of the machine, the mechanical seal will be quickly burned out, causing large-scale leakage of corrosive chemicals.

4. Media temperature classification: Standard sealing kit is suitable for ≤ 120°C ambient temperature media; For high-temperature conditions of 120~350°C, high-temperature resistant metal wrap sealing and external cooling and flushing piping must be selected.

5. Explosion-proof operating requirements: When transporting flammable and explosive organic solvents such as alcohol, ketones, and esters, the entire machine must be equipped with an explosion-proof three-phase motor. Ordinary motors without explosion-proof protection pose a risk of fire and explosion.

6. Corrosion strength classification: For strong hydrochloric acid and high-chloride ion media, 316L stainless steel current-flowing components must be selected; For conventional weak acids and alkalis, using 304 stainless steel can control procurement costs.
