Frequently Asked Questions

What is a hydrocyclone and how does it work?

A hydrocyclone uses centrifugal force generated by pressurized fluid flow to separate particles or immiscible liquids based on density differences. It has no moving parts and is highly efficient for oil-water or solid-liquid separation.

Can your equipment handle high-viscosity fluids?

Yes, our ultra-fine desanders and hydrocyclones are designed to operate effectively even in high-viscosity environments such as heavy crude or reactor catalyst slurries.

Do you offer customization?

Absolutely. We provide customized skid designs, material selections (including ceramic liners), and integration support to match your specific process requirements.

Is leasing available for short-term projects?

Yes, we offer flexible leasing options for Compact Flotation Units, desanders, and dewatering packages for temporary or emergency use.

Where is your factory located?

Our manufacturing facility is located in Shanghai, China, at the mouth of the Yangtze River, providing excellent logistics and shipping access.
