The role and value of asphalt insulation pump in the industry of use

The situation where the head of the asphalt insulation pump is lower than the operating point head is often encountered in practice. One situation is that when selecting the pump, the head is too high, but in actual use, the pump is used with a reduced head; Another situation is that it is difficult to determine the operating point of the pump during use, in other words, the flow rate of the pump needs to be adjusted frequently; There is also a situation where the pump needs to be frequently relocated for use. These three situations may overload the pump and affect its usability. It can be said that for pumps without full head characteristics (including submersible sewage pumps), their range of use will be greatly limited.
