Industria del teñido y acabado de textiles
Wet processing in textile production is of paramount importance, requiring the safe and stable conveyance of liquids such as dyes, auxiliaries, hot water, and wastewater. These fluids frequently contain corrosive chemicals, high temperatures, suspended particles, and varying viscosities, leading to pump corrosion, leakage risks, high clogging probabilities, and unstable suction. Furthermore, wastewater streams may contain fibres, sludge, or impurities, exacerbating equipment wear and reducing pumping efficiency.
Changyu pumps address corrosion, leakage, clogging, abrasion, and flow-control issues across all dyeing processes. We also provide customized materials, structures, and configurations tailored to each plant’s specific operating conditions.

Custom Pumps for the Textile Dyeing & Finishing Industry
Acid & Alkali
Recommended Pump Type: Magnetic Drive Pump
Reason: Full-sealed magnetic design stops leaks, handles corrosive dyes and chemicals with ease, and keeps maintenance super low thanks to 316L or fluoroplastic wetted parts.
Hot Water
Recommended pump type: Bomba autocebante
Reason: Built for 100°C+ hot water transfer, easy start without pre-filling, and stable performance with anti-block filters for dyehouse stations.
Application in Textile Dyeing & Finishing Industry
In textile dyeing & finishing industry, whether handling dyes, auxiliaries, hot water or wastewater, Changyu pumps deliver stable conveyance performance even when the fluid is corrosive, high-temperature, highly viscous or fibre-laden. Our pumps enable enterprises to effectively reduce downtime, lower energy consumption, enhance production efficiency and minimise operational costs through zero-leakage operation, robust corrosion resistance, straightforward maintenance and extended service life.
We offer tailored materials, structures, and control options to match each plant’s media, temperature, corrosion level, and flow requirements.
Dye Transfer
Viscous dyes often cause unstable flow, frequent clogging, and inconsistent feeding accuracy
Advantages: Our diaphragm pumps keep thick dyes moving smoothly with anti-clog design and adjustable flow, delivering steady and accurate dosing with minimal maintenance.
Auxiliary Dosing
Precise additive dosing is hard due to variable viscosity and easily fluctuating pressure conditions
Advantages: Our metering-ready diaphragm pumps offer fine flow control, stable pressure, and clean, leak-free operation for highly accurate auxiliary injection.
Hot Water Circulation
High-temperature loops create cavitation, vibration, and reduced pump life in dyeing systems
Advantages: Our self-priming and centrifugal pumps handle 100°C+ water with low NPSH design, stable flow, and durable stainless-steel components.
Wastewater with Fibres
Fibres and sludge easily clog conventional pumps and cause efficiency drops and shutdowns
Advantages: Our anti-block flow paths and corrosion-resistant materials ensure smooth wastewater transfer, reducing clogging and extending service life in harsh conditions.
