What aspects should we pay attention to when purchasing Parker piston pumps? What are the selection principles for Parker piston pumps? Many people face this problem when faced with choices. Faced with this situation, we need to know and understand some knowledge regarding the selection principles of Parker piston pumps. 　　The Parker plunger pump is a widely used general-purpose mechanical device that is applied across various sectors such as petroleum, chemicals, power and metallurgy, mining, shipbuilding, light industry, agriculture, civil use, and defense; it holds an important position in the national economy. According to statistics from 2002, China’s pump production reached over 2 million units, and the electrical energy consumed by pumps accounted for more than 21% of the country’s total electrical energy consumption. As an energy-efficient hydraulic pump, the Parker plunger pump plays a very important role in helping to save energy. 　　At present, in various sectors of the national economy, due to improper selection, many pumps are operating under suboptimal conditions, resulting in low efficiency and significant energy waste. Some pumps cannot be used at all due to improper selection, or their operation and maintenance costs are high, resulting in low economic efficiency. It can be seen that the proper selection of Parker piston pumps is also of great significance for energy conservation. 　　The so-called rational selection of Parker piston pumps involves taking into account a range of technical and economic factors such as the investment and operating costs associated with the pump unit and the pumping station, in order to ensure that it meets the principles of economy, safety, and suitability. Specifically, there are the following aspects: First: It is necessary to meet the requirements regarding flow rate and head; that is, the operating point of the pump (the intersection of the device’s performance curve and the pump’s performance curve) must remain within the high-efficiency range at all times. This not only saves energy but also helps to prevent damage to the mechanical components. 　　Second: The selected Parker piston pump should be small in size, light in weight, and inexpensive, while also possessing good performance characteristics and high efficiency. 　　Third: it has good cavitation resistance, which not only reduces the construction requirements for the pump’s structure but also prevents cavitation, ensuring stable operation and a long service life. 　　Fourth: Pumping stations can be built using the selected Parker plunger pumps, resulting in low project investment and low operating costs. 　　When selecting a Parker piston pump, by following the above selection principles for such pumps and taking one’s own requirements into account, it is possible to choose a Parker piston pump that is suitable for one’s needs. Another thing to keep in mind is that choosing a good agent for Parker piston pumps is also an important criterion for selecting such pumps. 　　The original text is from Parker plunger pumps: http://www.aotuoshi.com/news_140.html
