Advantages of Claw Pump

Corrosion free
While the pump doesn't use lubricants, it is susceptible to condensation with constant use. However, the vertical claw pumps are free draining. Therefore, there won't be any prolonged condensation within the pump, leading to fewer chances of corrosion and other related damages.

More flexibility
In certain dry vacuum pumps, the rotors contain a layer of coating that is very sensitive to temperature fluctuations. Moreover, recoating them becomes a very costly affair. However, due to a lack of coating on these rotors, the dry claw vacuum pump can withstand a broader temperature range of inlet gases and fluids, offering more leeway for operators in terms of process parameters.

Easy to replace and service
One of the most distinct advantages of a dry claw pump is its modular design. If one of the claws gets worn out or damaged, then it can be replaced separately instead of a complete systems overhaul. Furthermore, this also makes it easier to maintain.

Handles volatile materials
When it comes to harsh work environments and working with gases or fluids that are volatile, then dry claw pumps are the perfect choice as they make the operation safe due to their dry mechanism.
