印度尼西亚采购需求：电力供应不明、建筑供暖、水利、污水处理、石油化工、矿业和冶金

I'm reaching out to check on the availability of a specific multistage pump that I'm interested in. Could you please provide me with current stock information and any additional details about the product? I would like to know its specifications, pricing, and lead time for delivery. If possible, it would also be great to get insights into any related products or alternatives you might have. I'm looking to make a decision soon, so your prompt response would be appreciated. Thanks!
