Buy Welch vacuum pumps from MSE Supplies at the best value.
Welch Belt-drive vacuum pumps are known for their ruggedness world-wide in the most demanding applications.
Key features making these pumps so reliable and durable:
- Low pump rpm to reduce frictional wear while minimizing reservoir temperature to lessen chemical activity
- High oil feed to pump models leads to cleanest oil lubricating the internal pump module
- Large oil reservoirs dilute contaminants ingested into the pump
DUOSEAL vacuum pumps are used in most common lab and industrial applications.
Welch vacuum pump oil is specifically formulated for the unique needs of vacuum pumps. Use of non-Welch vacuum pump oil voids any performance claims and product warranties.
In DuoSeal belt driven rotary vane pumps, use Welch DuoSeal or Welch Gold Oil.
