Rocker 800 Vacuum Pump - 115V/60Hz (167800-11)

This is a good vacuum pump but don't expect it to vacuum much below -80 kPa. What is more the threads on the nipple and the threads that are tapped in the vacuum pump are tapered. I had to order a nipple that was tapered on one end and had a standard pipe thread to adapt to my set up.

Every time I ran across this challenge I have been set back at least two days until I was able to purchase the fittings that I need to get the job done.If need a vacuum pump and need to ensure that you can get down to -90 kPa or lower then look at a two stage rotary vacuum pump.Four stars for quality of product. -1 star for not suiting my needs. I will keep this item as a back up for other equipment that I have that don't need a deep vacuum to operate.

Great little pump, this is our third Rocker 400 and each has exceeded our expectation and functioned day in and day out without missing a beat. Low noise output and a reasonable base pressure. One is used in a 1-2 hour a day application and two pumps are used in an 8+ hour a day application. I would recommend a primary water trap in front if there is a chance liquid could reach the pump. The price here is as cheap as we have seen.

We use this for laboratory aspiration. It aspirates well and is much more quiet than our other aspirators. Would recommend!

Nice product

Great vacuum stability and quiet operation. best buy!
