Pumping while traveling?

I'll be traveling internationally for work in November without my LO for a week. She'll be 4 months old and is EBF. I'm wondering if it's feasible to bring my pump and just pump and dump to keep my supply up while I'm away.

I also am not sure if I can bring my breast pump (Spectra S2) and the parts and a bottle or two or if it's easier to just buy a manual hand pump or maybe hand expressing. I'll be traveling in and around a few towns so I can't bring anything too bulky in addition to my luggage.

Has anyone else ever been in this position? I'd appreciate any and all advice. Thanks!
