2.60 Electrical Power
2.61  Power Source Review
 

Review the power source and the motor rating to be sure they agree in voltage, phase, and frequency. 
Serious damage may occur to the motor if it is connected to an improper voltage. All Welch pumps must 
be grounded. Grounding reduces the risk of electric shock in the event of an electrical short circuit. The  
plug must be plugged into a properly grounded outlet. Consult your local electrical codes if you have 
doubts. 

2.62  Servicing of Double-Insulated Product 
 

In a double-insulated product, two systems of insulation are provided instead of grounding. No grounding 
means is provided on a double-insulated product, nor should a means for grounding to be added to the 
product. Servicing of a double-insulated product requires extreme care and knowledge of the system and 
should be done only by qualifi ed service personnel. Replacement parts for the double-insulated product 
must be identical to those parts in the product.

2.70 Vacuum Connection
2.71  For best results, Welch recommends the length of the tubing between the pump and the chamber be kept 

as small as possible.

2.80 Vacuum Gauges
2.81  All Aspiration/Filtration Vacuum Systems come with dial vacuum gauges. The vacuum gauge gives 

negative pressure - That is pressure below atmospheric. The reference point for the gauge is 
atmospheric pressure.

2.90 Traps
2.91  The need for a Trap
 

Model 2511 pumps are resistant to moisture-induced corrosion. The collection vessel has a fl oat valve is 
attached to the regulator assembly to prevent water condensate from accidentally being ingested into the 
pump.  An in line hydrophobic fi lter provides further protection against moisture ingestion. 

WARNING

The pump is not recommended for pumping acid, base or organic vapors 

or gases. Serious damage to the pump will shorten the pump’s service life. 
In addition, pumping fl ammable vapors or gases can lead to serious safety 

hazard leading to fi re or explosion.
