Gast 87R647 vacuum pump overview
The Gast 87R647 is an oil-free twin cylinder vacuum pump rated at .5 horsepower and designed for 110-120V or 220-240V operation. It suits laboratories, medical devices and light industrial systems that need clean, lubrication-free vacuum without oil contamination. The UL and CE approved unit weighs 19.1 lbs and arrives in OEM packaging ready for integration.
Sustained load performance
With a 100 percent duty cycle the pump runs continuously without overheating thanks to built-in thermal protection. Flow reaches 4.1 cfm at 50 Hz and 4.8 cfm at 60 Hz while maximum vacuum holds at 28 in-hg across both frequencies. The patented crossover chamber and flexible cup with twin seals maintain stable pressure up to 30 psi during extended operation.
Upgrade path and fit
The 87R series replaces older rocking piston pumps that require oil changes or produce higher exhaust temperatures. Its sound-dampening design and optional Sound Shield accessory cut noise by up to 25 percent dB(A) and 40 percent Sone. Buyers needing deeper vacuum than 28 in-hg or flow above 4.8 cfm should consider larger displacement models instead.

Questions about this item
How much noise and heat does the 87R647 produce when running continuously at 100% duty cycle?
The patented crossover chamber dampens sound and the pump runs with lower exhaust temperatures; an optional Sound Shield kit can cut noise by up to 25% dB(A) and 40% sones.
What electrical supply must I already have to wire the 87R647 for 240V operation?
You need a 220–240V circuit capable of 6.2A; the motor must be re-wired for the higher voltage before use.
Will the 87R647's 1/2HP motor and 4.8 cfm flow at 60Hz keep up with my older lab manifold?
At 60Hz it delivers 4.8 cfm and 28 in‑hg max vacuum, matching or exceeding many legacy oil‑less pumps of similar horsepower.
