FAQ - Frequently Asked Questions about Chemical Pumps

FAQ - Frequently Asked Questions about Chemical Pumps 1. Question:H ow to prevent evacuation, cavitation phenomenon  in operation ? Answer:      Take the air empty: if the pump has gas and liquid, the pump can not work, the flow and pressure tend to zero. Cavitation: is occurring in the pump during operation, from the medium within the pump, flow and pressure changes and fall, resulting in hydraulic shock. Usually take the air empty out of the pump is caused by a phenomenon in the pump, due to the installation of technical pipeline leakage, inhalation of gas caused by the evacuation has been rare, most of them are due to changes in operation and process caused. In order to avoid or control the occurrence of cavitation, in the operation of the pump flow to moderate, to minimize the pressure and the temperature can not appears to be greater change. In the pump suction line should prevent the gas from staying, the inlet pressure is...

Basic k nowledge of chemical pumps  and how to select a right pump How to choose the most suitable pump, has been a matter of concern to people.Different occasions, different media, different materials .choose the right chemical pump does not seem so easy. We have here in the election of the most important aspects of the election pump knowledge. To choose the pump, we must first understand and master the principles of chemical pump selection. 1.  The selected pump type and performance in line with the device flow, head, pressure, temperature, cavitation flow, suction and other process parameters. 2.  M ust  clarify  the requirements of medium characteristics. On the transport of flammable, explosive toxic or expensive media pump, requires a reliable seal or the use of leak-free pumps, such as magnetic drive pump, diaphragm pump, shield pump. 3.  The transmission of corrosive media pump,mechanical reliability, low noise, vibration. 4....
