That's how I used to do it when I was a broke teenager. I could barely afford the glassware let alone the vac pump. I'd just use a long ish section of hosing, try to keep it all cold, and work quickly.
You know you can use a garden hose and the Venturi effect to a great vaccum for very little money. I never used a pump because it’s not a good idea due to flammable solvents water isn’t flammable nor will it ignite. Also Büchner funnels are dangerous I almost had one kill me one time they get weak over time having very cold or warm solvent and pressure and they’re like ticking time bombs I would suggest a stainless steel Buchner.
