美国采购需求：天然油、卡斯蒂利亚肥皂、护手霜、护肤品

I recently purchased an oil pump from your company, but unfortunately, it seems to be malfunctioning and not working as expected. I've followed all the setup instructions, but I can't get it to operate properly. I would appreciate your immediate assistance in resolving this issue. Could you provide me with potential troubleshooting steps or let me know if a replacement or repair is possible? Additionally, I'd like to inquire about the range of oil pumps you offer. Understanding the specifications and features of your various models will help me make a more informed decision for future purchases. If you have a catalog or any promotional materials available, please share those with me. Looking forward to your prompt response regarding both the malfunctioning pump and additional product details.
