As its name clearly indicates, a dry claw pump does not need any liquid to seal and lubricate the machine. This is the biggest reason why it is considered as the one of the most robust and capable vacuum pumps to cope with harsh working conditions. In addition, just like their rotary tooth counterparts, the pump is also using two counter-rotating parts to perform its expansion and compression function. These rotating components are mounted close to each other but without directly getting in contact, only with very minimal clearance between them.
As the two claws are spinning inside the compression chamber, they suck in air via the inlet. With each of these new intakes, the pump concurrently compresses each pocket of air being drawn inside the housing. There are two compression cycles involved with each full rotation of the spinning claws.
When it comes to applications, a dry claw pump is perfect for those that dread high maintenance levels and heightened process compatibility. They are also ideal for operations involving harsh environments, such as the case with wastewater treatment plants and operate more efficiently than other kinds of pumps such as the rotary vane pump.
Finally, as this pump technology is possible to be integrated into a multi-claw pumping system, it can be easily matched to suit the unique requirements of your facility. So, if you also wanted to know if your own facility can greatly benefit from the reliability and durability of this vacuum pump, just get in touch with one of our experts here.
