chemical mechanical polishing with peristaltic pump

Keywords:peristaltic pump
polishing

Chemical mechanical polishing refers to the process of achieving high planarization of the material surface under certain process conditions by using a polishing machine, a polishing liquid, a polishing cloth, etc., wherein the supply of the polishing liquid is completed by a peristaltic pump, and the liquid of the peristaltic pump during the polishing process is Deliver the polishing fluid.
   The unique structure of the pumping liquid and the pump body are strictly separated, and the pump tube and the pump head can be replaced at any time. In the chemical polishing process, the polishing liquid delivered by the peristaltic pump always flows in the pump tube without contacting the pump body. In particular, it does not come into contact with the mechanical transmission mechanism, avoiding metal contamination during the chemical mechanical polishing process, and does not damage the mechanical components of the pump body due to the corrosiveness of the polishing liquid.
 
   During the working process, the peristaltic pump can generate enough vacuum suction to suck the polishing liquid from the liquid pool into the pump tube, thereby eliminating the filling process of the previous irrigation pump and the suction tube. This also eliminates the need to flood the water, so it is no longer necessary to be placed below the liquid source level, making the pump's mounting position more flexible and better integrated with the polishing machine itself. In addition, the peristaltic pump will not lose water, which can save unnecessary waste.
 
   The peristaltic pump is very simple to operate and can be used out of the box. The installation of the pump head can only be installed within a few minutes by hand screwing. The installation, disassembly and locking of the pump tube can be carried out at any time according to requirements, without any tools. In addition, the peristaltic pump is simple to control, and the speed control can be performed by using a dial pad or a keypad, and the more complicated tasks can be programmed and controlled through the menu mode. According to the flow requirement, a peristaltic pump can also be connected to multiple pump heads at the same time to realize multi-feed of polishing liquid.

Peristaltic pumps are typically used to pump clean/sterile or aggressive fluids without exposing those fluids to contamination from exposed pump components. Some common applications include pumping IV fluids through an infusion device, apheresis, aggressive chemicals, high solids slurries and other materials where isolation of the product from the environment, and the environment from the product, are critical. It is also used in heart-lung machines to circulate blood during a bypass surgery, and in hemodialysis systems, as the pump does not cause significant hemolysis.
Peristaltic pumps are also used in a wide variety of industrial applications. Their unique design makes them especially suited to pumping abrasives and viscous fluids.

Flowrate is0.007~2280ml/min. Flow speeds can be adjusted either by hand through switching knobs, instead of the traditional way of membrane keypad, which reduces obviously the failure rate, or by automatic control through the external controller interface, with three available modes: 0-5V, 0-10V and 4-20mA. Memory function is also available in the product in case of power off. Besides, switching knobs are designed clearly so that it is easy to operate for customers. FULL SPEED button available for filling in & emptying out. Good capability price rate. Not suitable when used in the open air.
