Frequently Asked Questions (FAQ)

What is a sintered inner outer rotor set?

A sintered inner outer rotor set is a precision-matched pair of rotors designed for oil pump systems, where the inner rotor drives and the outer rotor supports smooth and efficient oil circulation. Manufactured using powder metallurgy, these sets provide high dimensional accuracy and long-lasting performance.
Where are these rotor sets used?

They are primarily used in automotive oil pumps, but also find applications in hydraulic systems, compressors, and industrial lubrication systems that require precise and consistent fluid transfer.
Why choose sintered rotors over conventional machined rotors?

Sintered rotors offer the advantage of near-net shape production, reducing machining costs while providing consistent quality, wear resistance, and the ability to create complex profiles.
How does Growth Industries ensure matching accuracy?

We manufacture the inner and outer rotors together under controlled tolerances, ensuring perfect synchronization and minimal internal leakage for maximum pump efficiency.
Can these rotor sets be customized?

Yes, we offer customized sizes, profiles, and material compositions to meet specific pump designs and performance requirements.
What materials are typically used?

Iron-based powder alloys with specific additives for wear resistance and strength are commonly used, tailored to the operating conditions of each application.
How does the design improve pump efficiency?

The close-fitting design between the inner and outer rotors reduces fluid leakage, providing a steady oil flow with minimal pulsation and improved system reliability.
What is the typical service life?

With proper lubrication and operating conditions, our rotor sets provide long-term, maintenance-free service in both automotive and industrial applications.
