IMPORTANT- Always check the oil level with the vacuum pump running oil seal rotary Vacuum pumps are not intended for use on Amonia or Lithium Bromide (salt water) systems. Both of these systems will cause the pumps to lock up and be rendered inoperable. Use of oil seal rotary pumps on either of these systems will void the warranty. IMPORTANT- …

Why do I need to check the oil level when the pump is running? The reason for this is that if the vacuum is not broken before pumps are shut down the oil in the cover will seek the vacuum still in the cartridge and intake chamber. Then the oil level will drop in the sight glass and give the …

How low of a vacuum should we pull on a system? JB recommends that a system be pulled to at least 250 microns and held at least five minutes. On any polyester oils in a system, it is recommended to pull a much lower vacuum as moisture is very difficult to remove even with heat and vacuum. vacuum leak detector …

Can I mount my micron gauge onto the vacuum pump? It is not recommended to do so as you are reading what the pump is doing and not what the pump is doing to the system (see DV-29). It is suggested that you tee off on the suction side of the system and mount the gauge there. vacuum leak detector …

I am able to pull a vacuum on my system, but when I blank-off, the micron gauge rises rapidly. Unless you are using JB`s DV-29, copper tubing, or flexible metal hoses, it is not recommended to use your existing manifold and hoses for blanking-off a system to check for leaks. Hoses work very well under high pressure. Vacuum is very …

I have been pulling a vacuum on my system using a micron gauge and cannot get it down to a low reading.https See FAQ #1. Another possibility is that some oil may have entered the micron gauge and is giving false readings. The remedy is to pour regular rubbing alcohol into the connector on the micron gauge, shake, and pour …

I have been using my low side gauge to pull a vacuum, is this wrong? YES. The low side gauge knows only atmospheric pressure and cannot sense moisture or non-condensables. A micron gauge is a heat sensing device that not only reads atmospheric pressure, but also measures the gases created by the vacuum pump as it boils the moisture. For …

How to select lab vacuum pumps When selecting a vacuum pump for lyophilization, evaporation or concentration applications, a vital consideration in pump performance is vapor tolerance. These applications tend to involve high vapor flows that make extra demands of the pumping capacity, so a pump that is designed to handle those vapors is important to your success. But what do …
