Rough Pump Cutout

29 04 2009

So the rough pump is cutting out after about 30 minutes. I spoke with the manufacturer, and two likely causes.

  1. The rough pump is set to 240V (it will run, but will eventually cutoff from overheating)
  2. The diaphram in the rough pump is worn out, causing overheating.

My guess is #2. Investigating.

Here are the rough pumps identifiers:


Mod: MVP-035 2001/01

Mod. – Nr. PKT01200

Lab note: The chamber holds ~150  Liters (0.15 Cubic Meters or 5.2 Cubic Feet). The pumps works at 40 l/s, so it would take 3 secs to rough the chamber? Does that sound right?
