Frequently Asked Questions (FAQ)
Q: When should I choose 304 stainless steel over cast iron or 316L?
A: Choose 304 stainless steel for applications involving mild corrosives like organic acids, alkalis, chlorinated water, or where hygiene and cleanability are priorities (e.g., food, pharma). It offers an excellent balance of cost and performance. Cast iron is suitable for neutral sewage only. Upgrade to 316L for highly corrosive media like strong acids or chlorides.
Q: Is the pump suitable for continuous operation?
A: Yes. It is designed for continuous duty. For enhanced safety, optional float switch and thermistor provide comprehensive protection against overload and overheating.
Q: Can you provide pumps with different discharge flange standards?
A: Yes. As a custom SS304 Sewage Pump manufacturer, we can provide various flange standards (DIN, ANSI, etc.) and voltages to meet your local requirements and ease installation.
Q: What is the maximum fluid temperature this pump can handle?
A: Standard models are suitable for fluids up to 40°C (104°F). For higher temperatures, please inquire about our customized high-temperature options.
