Gear pump is urgently needed
Thread Content
Does any fellow sailor know the best manufacturers of gear metering pumps in China? I really need one urgently; it’s intended for use in an experimental setup, with a flow rate of 5–30 liters per hour, a power consumption of around 0.37 kW, and connections of 6 mm diameter. Material: 316L, frequency adjustable.
I’m not very familiar with those available in China; as for microgear metering pumps from abroad, they are quite good.
Middendorf, VIKING, and the like are all excellent; their prices are not high either. There are agents of these products everywhere in the country, and they generally don’t break down. We’ve been using them for over 10 years, and some even for 30 years. Why buy domestic ones? Performance is unstable.
The main reason is that the project timeline doesn’t allow the use of imported materials
For some imported pumps, the manufacturers also have stock, so it’s worth asking.
The quality of domestic metering pumps is more than satisfactory; we have been using them. We use those produced in Cixi.
Chongqing Pump Factory produces metering pumps, but the quality is average. It can operate continuously for up to half a year. After half a year, the drive mechanism generally requires major repairs; therefore, we have to disassemble and inspect each new pump again, adjusting the clearances between its various components. A pump that has been adjusted in this way can usually operate continuously for about two years. There are also domestic options from Dalian Laore, and their pumps are more or less the same.
...I found that many people above didn’t improve their comments as requested by the original poster. . The other party wants a gear metering pump, right? Miltonroy, is that it? There should be suitable models available for micropump and VIKING, as well as for Taihe Microstar magnetic gear pumps. It seems that Taihe offers better prices; you might want to ask your local agent about this
