越南采购需求：水表、流量计、家用水表、劳拉水表、水流量计、水价表

I am interested in purchasing some DN50 pumps for an upcoming project. Could you please provide details on the specifications, pricing, and availability? Additionally, I'd like to know about the shipping options to Cambodia, including estimated delivery times and any associated costs. It would be great if you could include information on bulk purchase discounts, warranty details, and after-sales support. This will help me make an informed decision. Looking forward to your prompt response so we can move forward quickly. Thanks!
