Sharing information on several long-life rotary piston pumps
Thread Content
I’m sharing pictures of a few pumps that have been in use for a long time for everyone to discuss – let’s see how long the pumps that others have used have been in operation. The company recently assigned some work to a petrochemical company, which included the replacement of pumps. There were over a dozen rotary piston pumps on site, installed outdoors; they were manufactured by Beijing Chemical Machinery Factory (now known as Lanxing IBC). The 20+ models have the shortest lifespan; those with a longer lifespan are older than me. Some of them are already 36 years old and still in good working condition. The reason for the replacement now is that the pump casing is made of cast iron, which does not meet current regulatory requirements. PS: Although it goes against the specifications, I personally think they shouldn’t be altered.
Based on what I know, here is information on several long-life rotary piston pumps: 1. Rotary piston pumps produced by Beijing Chemical Machinery Factory (now known as Lanxing): These pumps have a very long service life, which can last for decades or even longer. Some pumps have been in use for over 36 years, under normal operating conditions. 2. The long lifespan of these pumps is possibly due, on the one hand, to their high quality in design and manufacturing, and on the other hand, to proper maintenance and care. These pumps are typically used in certain industries such as the petrochemical industry, and they are often installed in outdoor environments. 3. However, since current regulations prohibit the use of cast iron for pump casings, these pumps need to be replaced. Although these pumps can still function properly, to meet the latest regulations, the pump casing needs to be made of materials that satisfy the required standards. Overall, the existence of these long-life rotary piston pumps proves their high quality and reliability. Although it is necessary to replace these pumps now, I personally believe that if they are still functioning properly, they should be kept in use as much as possible instead of being replaced. .
What does 36 years mean? I’m not sure if it has been overhauled at any point
As far as I know, it hasn’t been overhauled. For routine maintenance work, Sinopec seems to do a pretty good job.
It’s really impressive; everything from design and manufacturing to delivery to the end user is reliable
Rotary piston pump, heard about it for the first time, need to learn more about it
