澳大利亚采购需求：交流线圈清洗机、蒸汽线圈清洗机、HAVC蒸汽清洗机、制冷真空泵、无火花真空泵、无火花真空泵

I recently encountered an issue with my cordless vacuum pump, where the filler cap has broken off. Instead of disposing of the entire unit, I was wondering if I could purchase just the replacement part for the pump or reservoir side that bolts into the motor. It seems inefficient to throw the pump away over a small broken piece. I'd appreciate any information on whether you offer replacement parts or solutions for this type of situation. Thanks!
