越南采购需求：潜水泵、排水泵、水下泵、离心泵、电动水泵、消防泵

I'm looking to procure a couple of stainless steel submersible sewage pumps. The specifications I'm interested in include a flow rate of approximately 220 m³/h and a head capacity of 65 m. Quality and durability are key factors for me, so please ensure that the pumps meet industry standards and can handle demanding conditions. Could you provide me with your pricing, lead times, and any certifications the pumps might have? Additionally, I would appreciate any recommendations or insights on these models, including warranty details and after-sales support. Looking forward to your swift response so we can move forward.
