1. Product core advantages

1. High-strength integrated injection-molded anti-corrosion pump body

The entire pump casing is integrally molded from imported engineering plastic, with three material options: FRPP, CPVC, and PVDF. The structure is dense and wear-resistant, resistant to acids, alkalis, and crystallization corrosion. Long-term transport of electroplating etching solution, chromic acid, and acid-alkali wastewater is less likely to crack and leak, extending the service life by 40% compared to split pump bodies.

2. Ultra-strong self-priming structure, eliminating frequent pumping needs

Built-in independent large-capacity self-priming chamber, with a standard maximum self-priming height of up to 20 feet. After pipeline drainage and shutdown, restarting without manual water filling or pump filling is needed. It can be directly installed outside the surface or underground liquid storage tanks, solving the traditional limitation of centrifugal pumps requiring low-level immersion installation, and is suitable for unattended production lines, exhaust gas scrubbers, and underground waste liquid pools.

3. Integrated high-efficiency hydraulic impeller

The impeller and pump body flow channel are integrated and optimized, resulting in lower hydraulic losses and higher operational efficiency, effectively reducing motor load; The smooth surface makes it difficult for plating slag and crystalline particles to cling, reducing impeller jamming failures, and suitable for long-term continuous operation of electroplating solutions containing suspended impurities and chemical waste liquids.

4. Customizable shaft sealing system for all working conditions

Sealing accessories can be freely combined according to chemical temperature, solvent, and corrosion strength: dynamic and static rings can be selected from ceramic or silicon carbide SIC (SiC wear-resistant and crystallization-resistant, preferably for electroplated slag-containing chemicals); Sealing rubber offers NBR/EPDM/VITON fluororubber; The springs uniformly use SUS316 stainless steel anti-corrosion springs, covering all scenarios including pure water, weak acids, strong chromic acid, and organic solvents.

5. Dual-frequency motors are compatible with domestic and international markets

Motors come in 50Hz domestic standard and 60Hz export version, with two selectable poles: 2-pole or 4-pole options, power coverage 0.37HP~5.5HP; The entire machine is coated with epoxy anti-corrosion coating, moisture-proof and rust-proof, meets protection standards, and is suitable for the high-humidity corrosive environment of electroplating workshops.

4. Applicable industries and working scenarios

1. Hardware electroplating production line

Nickel, copper, zinc, decorative chrome, and hard chrome plating tanks circulate outside the tanks, delivering the chemical solution over long distances to the HL/HXL series filters; The self-priming structure does not need to be placed inside the plating tank; both surface and underground storage tanks can be installed. Even if the liquid level fluctuates or sediment at the tank bottom blocks the suction port, the machine will not run idle and burn out.

2. PCB circuit board manufacturing industry

Chemical transport in acidic/alkaline etching tanks, micro-etching tanks, and development tanks; PVDF pump bodies are resistant to strong acid and alkali etching corrosion; Paired with an activated carbon filtration unit, it circulates and purifies the surface chemical, reducing pinholes and oxidation defects on the panel.

3. Environmentally friendly exhaust gas scrubber tower equipment

Acid-alkali exhaust gas neutralization spray system: The pump body is installed next to the underground liquid storage tank. After shutdown, the chamber retains the liquid liquid, which automatically draws liquid on the next startup, eliminating the need for manual frequent water refilling. It is suitable for factory unattended environmental protection equipment.

4. Chemical wastewater treatment station

Electroplating comprehensive heavy metal wastewater and acid-base neutralization waste liquid are transported by long-distance lifting and transport, transporting the waste liquid to the neutralization tank and filter press; The high-flow 70-caliber model is suitable for small to medium-sized integrated wastewater treatment equipment.

5. Plastic chemical plating and electrophoretic coating

The ABS plastic roughened chromic acid tank uses PVDF + fluororubber sealing to resist strong oxidation corrosion from chromic anhydride; The electrophoretic paint production line uses low-wear impellers to prevent paint clumping and particle pitting, ensuring uniform coating of workpieces.

6. Precision pure water cleaning equipment

RO pure water and ultrasonic cleaning solvent are circulated and conveyed, paired with HK stainless steel precision filters to filter rust and colloidal impurities in water, adapting to electronic component cleaning processes.

5. Selection Considerations

1. Pump body material classification: FRPP is used for room temperature weak acids and alkalis; CPVC can withstand moderate temperature and acid-alkali temperatures within 80°C; PVDF is specifically supplied with chromic acid, strong oxidizers, and high-temperature, highly corrosive chemicals.

2. Head-type distinctions: L Low head suitable for short pipelines up to 10 meters; H high head is suitable for high vertical height, long pipelines, and multiple filters connected in series.

3. Shaft seal material recommendation: Electroplating contains metal crystals; the plating slag solution should use SIC silicon carbide dynamic and stationary rings; Clean pure water, and the cleaning solution uses ceramic dynamic and static rings; For solvent-containing high-temperature chemical seals, VITON fluororubber must be used.

4. Power supply frequency classification: domestic factory 50Hz models; For exported 60Hz models overseas, the two head-to-flow curves are independent and cannot be mixed.

6. Supporting services and after-sales guarantee

1. Free professional selection of working conditions: Based on plating tank volume, pipeline distance, chemical corrosion content, and temperature, we match pump body material, power, head model, and sealing kit, providing a customized selection plan.

2. Non-standard customization services: full PVDF anti-corrosion complete machines, extended self-priming chambers, 60Hz export dedicated motors, full sets of fluororubber seals, and specially customized titanium anti-corrosion springs.
