Rotary Pump FAQ Section
Q: What are the main advantages of using a rotary pump over other pump types?
A: Rotary pumps offer several advantages including smooth, pulse-free flow, ability to handle viscous fluids, self-priming capabilities, and high efficiency across a wide range of operating conditions. They're particularly valued for their reliability in continuous operation scenarios and their capacity to maintain consistent flow rates regardless of pressure changes.
Q: How often should maintenance be performed on a rotary pump?
A: Routine maintenance for rotary pumps typically includes checking seals and bearings every 3-6 months, with complete overhauls recommended every 2-3 years depending on usage intensity. However, our models feature extended service intervals with some components lasting 5+ years under normal operating conditions. Always refer to the specific maintenance schedule in your pump's manual.

Rotary Pump FAQ Section
Q: Can rotary pumps handle abrasive fluids?
A: While standard rotary pumps aren't designed for highly abrasive fluids, we offer special models with hardened components and protective coatings that can handle mildly abrasive media. For extremely abrasive applications, we recommend considering progressive cavity pumps or discussing your specific requirements with our engineering team for a customized solution.

Rotary Pump FAQ Section
Q: What's the typical lifespan of a rotary pump?
A: With proper maintenance and under normal operating conditions, our rotary pumps typically last 7-10 years before requiring major overhaul. Many components, especially in our premium models, can last the entire service life without replacement. Actual lifespan varies based on factors like operating hours, fluid characteristics, maintenance practices, and environmental conditions. We've documented cases of our pumps operating reliably for 15+ years in favorable conditions.
