Pompa lumpur pewarna dan pompa lumpur pigmen pemilihan secara langsung menentukan keandalan dan biaya operasional lini produksi pewarna dan pigmen. Di Changyu Pump, kami telah mengidentifikasi tiga kesimpulan utama bagi para insinyur yang menentukan spesifikasi pompa ini:
- Ketahanan korosi adalah persyaratan utama — lumpur pewarna dan pigmen mengandung asam sulfat, asam klorida, asam nitrat, dan pelarut organik yang dengan cepat merusak material pompa standar.
- Pemilihan material harus sesuai dengan kondisi proses — UHMW-PE untuk lumpur asam di bawah 90°C, FEP/PFA untuk pelarut organik dan oksidator kuat, serta baja tahan karat untuk aplikasi suhu tinggi (hingga 180°C) atau partikel kasar.
- Tiga seri pompa mencakup seluruh spektrum proses — seri UHB (dilapisi UHMW-PE), CYB-ZKJ (dilapisi FEP/PFA), dan HB (baja tahan karat) menangani berbagai suhu, kimia, dan konsentrasi padatan yang ditemukan dalam manufaktur pewarna dan pigmen.
Mengapa Lumpur Pewarna dan Pigmen Memerlukan Pompa Lumpur Pewarna Khusus?
Produksi pewarna dan pigmen melibatkan beberapa tahap — diazotasi, kopling, filtrasi, pengeringan, dan penggilingan — masing-masing menghasilkan fluida proses dengan tantangan yang berbeda. Media yang dipompa biasanya mengandung:
- Asam sulfat, asam klorida, atau asam nitrat pada berbagai konsentrasi, digunakan dalam reaksi nitrasi dan sulfonasi
- Pelarut organik seperti benzena, alkohol, dan ester, digunakan dalam sintesis dan pemurnian
- Partikel padat halus (0,1–1 mm) kristal pigmen, zat antara pewarna, dan residu kue filter
- Fluktuasi suhu dari suhu sekitar hingga 120°C atau lebih tinggi selama transfer lumpur tahap pengeringan
Kondisi gabungan ini — asam kuat, pelarut organik, dan padatan abrasif — dengan cepat merusak pompa logam standar dan menyebabkan kegagalan lapisan pada pompa plastik konvensional. Sebuah pompa lumpur pewarna yang tahan korosi oleh karena itu harus menawarkan ketahanan korosi, toleransi abrasi, dan kompatibilitas kimia dengan media organik secara bersamaan.
Di Mana Pompa Lumpur Pewarna Digunakan dalam Lini Produksi Pigmen?
Pompa lumpur pewarna Aplikasi mencakup seluruh rantai produksi:
| Tahap Proses | Media yang Dipompa | Tantangan Utama |
|---|---|---|
| Pelarutan asam | H₂SO₄ pekat, HNO₃ dengan zat antara pewarna | Korosi ekstrem, suhu tinggi |
| Diazotasi & kopling | Lumpur asam dengan partikel pewarna yang mengendap | Kombinasi korosi + penanganan padatan |
| Penggilingan & dispersi pigmen | Lumpur pigmen dengan padatan 10–30% | Keausan abrasif dari kristal pigmen keras |
| Umpan filtrasi | Lumpur kue filter kepadatan tinggi | Konsentrasi padatan tinggi, viskositas tinggi |
| Pemulihan pelarut | Pelarut organik dengan asam sisa | Serangan kimia pada elastomer dan lapisan |
| Netralisasi limbah | Asam bekas dengan endapan logam berat | pH bervariasi, komposisi tidak dapat diprediksi |
Lini produk Changyu Pump mencakup setiap tahap ini dengan konfigurasi material dan penyegelan yang dirancang khusus.
Material Pompa Apa yang Tahan Korosi untuk Aplikasi Pompa Lumpur Pigmen?
Pemilihan material adalah faktor penting dalam pompa lumpur pigmen keandalan. Material yang salah menyebabkan penipisan dinding yang cepat, delaminasi lapisan, atau kegagalan segel poros dalam hitungan minggu.
UHMW-PE (Polietilena dengan Berat Molekul Sangat Tinggi)
UHMW-PE menawarkan ketahanan kuat terhadap asam klorida dengan konsentrasi berapa pun, asam sulfat hingga 80%, dan sebagian besar larutan alkali. Seri UHB Changyu Pump menggunakan struktur UHMW-PE berlapis baja dengan ketebalan lapisan 8–20 mm, memberikan lebih dari sembilan kali ketahanan aus baja karbon. Cocok untuk suhu lumpur hingga 90°C.
Fluoroplastik FEP / PFA
Untuk media yang mengandung asam nitrat (hingga 50%), oksidator kuat, atau pelarut organik, lapisan FEP (fluorinated ethylene propylene) dan PFA (perfluoroalkoxy) adalah pilihan yang tepat. Seri CYB-ZKJ menangani suhu dari -20°C hingga 120°C (PFA hingga 260°C) dan tahan terhadap pembengkakan serta serangan kimia yang dapat merusak lapisan non-logam.
Baja Tahan Karat (304 / 316L / Duplex)
When process temperatures exceed 120°C or when the slurry contains abrasive particles larger than 0.3 mm, all-stainless-steel construction is necessary. The HB series, made from 304, 316L, 2205 duplex, or 2507 super duplex stainless steel, operates reliably up to 180°C and handles particles up to 1 mm without the risk of liner delamination.
Which Dye Slurry Pump Series Does Changyu Pump Recommend?
Kami merekomendasikan three product series for dye and pigment production, each engineered for a specific range of process conditions.
1. UHB Series — UHMWPE Lined Chemical Slurry Pump
Suitable for: Acidic dye slurries, spent acid transfer, general pigment slurry circulation at moderate temperature.
The UHB series is a commonly specified yang tahan korosi for chemical processing. Its steel-lined UHMW-PE construction provides:
- Laju aliran: 3-2.600 m³/jam
- Kepala: 5-100 m
- Kisaran suhu: -20°C hingga 90°C
- Solids tolerance: Up to 40% fine particles
- Pilihan segel: K-type dynamic seal, mechanical seal, or packing seal
The semi-open impeller design reduces clogging from pigment crystals and filter residues, while the K-type dynamic seal with cooling water circulation supports continuous operation.
2. CYB-ZKJ Series — FEP/PFA Lined Corrosion Resistant Slurry Pump
Pompa Lumpur Horisontal Tahan Korosi Seri CYB-ZKJ
Suitable for: Organic solvents, strong oxidisers, high-temperature pigment synthesis, and dyeing wastewater.
The CYB-ZKJ series uses imported FEP or PFA fluoroplastic lining with a sintered forming technology that resists cracking and peeling. Key parameters:
- Laju aliran: 3-2.600 m³/jam
- Kepala: 5-100 m
- Kisaran suhu: -20°C to 120°C (PFA to 260°C)
- Medium tolerance: Sulphuric acid ≤80%, nitric acid ≤50%, hydrochloric acid any concentration, organic solvents
- Seal: Dual-end mechanical seal
The CYB-ZKJ series is documented in our product data as suitable for the dyeing industry and for conveying corrosive organic solvents including benzene, alcohols, and esters. The semi-open impeller handles slurries containing up to 20% soft particles.
Typical application: A 100CYB-ZKJ pump with PFA lining handling coupling-stage slurry containing mixed organic solvents and 15% suspended dye solids at 95°C.
3. HB Series — Stainless Steel Abrasive Slurry Pump
HB Series Stainless Steel Abrasive Slurry Pump
Suitable for: High-temperature pigment milling, abrasive filter cake transfer, and processes where lined pumps cannot be used.
The HB series is an all-stainless-steel horizontal centrifugal pump designed to ISO 2858 and CE standards, engineered for abrasive and medium-corrosive slurry transport. Key specifications:
- Laju aliran: 10-60 m³/jam
- Kepala: 20-120 m
- Kisaran suhu: -20°C hingga 180°C
- Particle size: 0.3–1 mm
- Bahan: 304, 316L, 2205 duplex, 2507 super duplex
- Pressure rating: ≥1,6 MPa
Unlike lined pumps, the HB series eliminates risks of liner delamination, bulging, or thermal creep — common failure modes in high-temperature pompa lumpur pigmen applications. Its semi-open impeller and stainless steel casing make it suitable for pigment milling circuits where hard crystal particles (TiO₂, iron oxide, carbon black) cause erosive wear in polymer-lined equipment.
Typical application: A 50HB-25 pump with 316L wetted parts moving mill-discharge slurry at 120°C, containing 30% solids with particle size 0.5–0.8 mm. Pump service life typically exceeds 5 years.

Professional Glossary of Slurry Pump Terms for Dye and Pigment Engineers
The following terms are commonly referenced in the dye and pigment pumping industry:
Dye Slurry Pump — A pompa sentrifugal designed to handle corrosive, particle-laden fluids in the production of synthetic dyes and intermediates. The pump must resist attack from sulphuric acid, hydrochloric acid, and organic solvents while maintaining hydraulic efficiency despite suspended solids.
Pigment Slurry Pump — A heavy-duty slurry pump engineered for the transfer of pigment dispersions, mill-discharge slurries, and filter cake in pigment manufacturing. Key requirements include abrasion resistance from crystalline particles and compatibility with high-temperature process streams.
Lapisan UHMW-PE — Ultra-High Molecular Weight Polyethylene lining applied to the internal wetted surfaces of a slurry pump. It provides wear resistance approximately nine times that of carbon steel and broad chemical resistance, making it a common material for acidic dye slurries.
