I’m looking for a pipeline pump that can deliver hot water; could anyone recommend one?
Thread Content
The model that was originally used was a pipeline pump of the gd65-19 type with a power output of 2.2 kilowatts. The bearings would often run out of oil due to the high temperature (around 80 degrees Celsius from the hot water), which caused the motor to burn out. Even if the motor didn’t get damaged, the bearings still needed to be replaced every three months or so. Whenever someone recommended a different model, it meant major repairs were required, so it was necessary to have the necessary materials on hand. The pipe diameter is 65.
An IRG tubular hot water pump will suffice; it’s a very common type of pump. In the past, when tubular pumps were used to transport fluids at temperatures above 80°C, external cooling water was required, but this problem has now been solved – no external cooling water is needed anymore. Just like ordinary tubular pumps, it is very convenient to use.

The person above mentioned professional hot water pumps, but from our actual experience, such pumps are generally made of carbon steel, and their impellers and pump shafts are prone to corrosion. So we asked the manufacturer to replace the impellers, pump shafts, and partitions with 304 stainless steel, and that solved the problem, haha. For high-temperature water, 12Cr is the preferred choice, as specified in the API standards. ——by flytointer
I think 304 stainless steel is sufficient for the parts where the medium flows through
It is advisable to use SG and SGR series hot water pipeline pumps, which are new types of vertical single-stage centrifugal pumps that offer significant advantages over the horizontal centrifugal pumps currently in use. As a replacement for conventional centrifugal pumps, this pump has taken the place of various older types of pumps. It is now widely used in various industries, and this has become a common trend.
