2BV series Liquid ring vacuum pump| Vacuum Pump|Vacuum .

2BV series water ring vacuum pumps are suitable for pumping the gases and steam. Its suction pressure can reach 33mbar (abs) (i.e. 97 % vacuum degree). If the transformer oil is used as the operating liquid, these pumps are called oil ring vacuum pump and the suction pressure can reach 6.7mbar (abs) (i.e. 99 % vacuum degree).

Maintenance Tip: Bearing Lubrication | NASH Solutions

The most common reasons for bearing problems are a lack of lubrication or the use of contaminated lubrication - and not the type of lubrication. Most NASH pumps have grease lubricated bearings. This does not imply that grease is better than oil, only that the equipment was designed that way.

Vacuum Pump Capacity Ratings - Technical Data | Dekker .

The capacity for vacuum pumps is specified in a couple of different ways, depending on the type of vacuum pump and the manufacturer. It is important to know the ACFM rating of the pump, which expresses the "actual cubic feet per minute" inlet capacity at a specific vacuum level.

Vacuum Pumps: Basic operation and maintenance tips .

Vacuum pumps have been getting a lot of press lately. Unfortunately, much of it has been negative, especially in the area of dry vacuum pumps. In this article, we will take a look at how vacuum .

Dry vs. Liquid Ring Vacuum Pumps for Solvent Handling

The most common and preferred vacuum pumps for han-dling solvents are Liquid Ring and Dry Pumps. Both types of pumps do not require internal lubrication which allows solvent vapors to be sucked through the pumps without jeopardizing their lubrication whereas oil sealed pumps such as rotary vane or piston that do require internal lubrication

Vacuum Pump Bearings - High Vacuum Bearings | Precision .

Vacuum Pump Bearings Vacuum pump bearings frequently operate in vacuum applications with challenging environmental requirements including temperature, contamination and reliability that can sometimes mean a special bearing or special lubrication is required to meet stringent requirements.

Premier Pumps

Are You Choosing the Right Seal for Your Vacuum Pump .

Mechanical seals can fail for many reasons, and vacuum applications present particular challenges. For example, certain seal faces exposed to vacuum can become starved of oil and less lubricious, increasing the likelihood of damage in the presence of already low lubrication and high heat soak from hot bearings.
