Description
It’s made of strong steel and sized just right – about 1.6 inches across and 1.6 inches tall, with thin 0.04-inch wire.
You’ll find it in the popular VC100 and VC150 models. These are the oil-lubricated rotary vane pumps used in labs, small factories, medical equipment, and workshops.
Over time, springs can get weak or break from constant use. When that happens, you might notice odd noises or the pump not holding vacuum as well.
