Description
Summary:Liquids that contain abrasive solids and fluids that can solidify pose special problems to the normal functioning of a pump. The key to trouble-free operation of a pump is knowing the nature of the pumpage (the liquid to be pumped) and how to accommodate its peculiarities. The materials commonly favored for their resistance to abrasion feature superior hardness and mechanical strength. Because of their ability to absorb the shock energy of abrasive particles, rubber materials provide an interesting solution to the problem of abrasion of parts exposed to the pumpage. In particular, when the abrasive particles are small, rubber-lining of the parts provides effective resistance to wear. A diaphragm pump uses a flat, flexible diaphragm that is hermetically sealed in a housing. The pumped liquid stays on one side of the diaphragm while a moving fluid on the other side imparts its pressure via the diaphragm.
