Apa fungsi rotor pada pompa ulir Sydex K-Series?

Rotor adalah komponen ulir yang berputar di dalam stator untuk menjebak dan mendorong fluida dari sisi hisap ke sisi buang. Materialnya harus tahan korosi dan abrasi.

Apa fungsi stator pada pompa ulir Sydex K-Series?

Stator adalah selubung elastis yang mengelilingi rotor dan menciptakan rongga di mana fluida bergerak. Pemilihan material stator, seperti NBR, EPDM, atau FKM, harus disesuaikan dengan jenis fluida dan suhu.

Bagaimana cara memilih material stator yang tepat?

Pemilihan material stator bergantung pada jenis fluida yang dipompa. NBR cocok untuk fluida berbasis minyak, EPDM untuk air dan bahan kimia ringan, sementara FKM untuk aplikasi bersuhu tinggi dan sangat agresif.

Mengapa material rotor dan stator sangat penting?

Pemilihan material yang tepat memastikan pompa beroperasi secara efisien, tidak cepat aus, dan memiliki masa pakai yang panjang. Material yang salah dapat menyebabkan kerusakan dini dan biaya perawatan yang tinggi.

Selecting the Right Rotor and Stator Materials for Sydex K-Series Screw Pumps

Selecting the right materials for the rotor and stator is key to ensuring that screw pumps operate optimally and have a long service life. For Sydex K-Series pumps, which are designed to handle various types of fluids, understanding material characteristics is very important. Winston Indonesia, as an official Sydex partner, is ready to help you make the right decision.

Introduction to Critical Components: Rotors and Stators

Rotor: A screw-shaped component that rotates inside the stator. The rotor traps and pushes fluid from the suction side to the discharge side.
Stator: A helical elastic casing or layer that surrounds the rotor. The stator creates a closed cavity through which the fluid moves.

The interaction between the rotor and stator enables the Sydex K-Series pump to efficiently pump viscous, abrasive fluids, and even those containing solid particles.

Selecting Rotor Materials

The rotor must be resistant to corrosion and abrasion, especially when pumping hard or chemically aggressive materials. Common materials used in Sydex K-Series pumps are:

Stainless Steel: Types such as AISI 304 or AISI 316 are commonly used due to their corrosion resistance. This is the standard choice for most industrial applications.
Duplex or Super Duplex Steel: Used for applications requiring very high corrosion resistance, such as in the chemical industry or in highly aggressive environments.

Selecting Stator Materials

The stator is made of elastomer (rubber) that must be flexible and resistant to chemicals, temperatures, and wear. The choice of stator material is crucial and must be tailored to the type of fluid being pumped:

NBR (Nitrile Butadiene Rubber): Ideal for pumping oil-based fluids, oils, and greases. NBR offers excellent resistance to these substances.
EPDM (Ethylene Propylene Diene Monomer): The ideal choice for pumping water, water-based liquids, or mild chemicals. EPDM has excellent resistance to acids and bases.
FKM (Fluoroelastomer): Known for its resistance to high temperatures and highly aggressive chemicals, making it the preferred choice for applications in the chemical and petrochemical industries.

In addition to the type of fluid, there are several other factors to consider:

Operating Temperature: High temperatures can affect the performance and lifespan of elastomer materials.
Abrasive Properties: Hard solid particles will accelerate stator wear, so selecting abrasion-resistant materials is very important.
Standard Certification: For the food & beverage or pharmaceutical industries, materials must meet FDA (Food and Drug Administration) standards.

Conclusion Choosing the right pump is not enough. Selecting the appropriate combination of rotor and stator materials is the next important step to ensure your investment in the Sydex K-Series provides maximum benefits.
