Need help with a high-temperature asphalt pump?
Thread Content
Could you please recommend manufacturers that produce high-temperature asphalt pumps, including both imported and domestic ones? Medium: modified asphalt； Operating temperature: 400 degrees. The key is a long service life, good performance, and low likelihood of leakage.

Important: Does the mechanical seal allow external flushing for PLAN32? (A seal flusher compatible with the medium allows external materials to enter the modified asphalt.)
It’s possible to do that. What’s your phone number? Or you can call Xu at 13783528006
Two types of pumps, one with a flow rate of 100 m3/h； It has a capacity of 15 m3/h, with a head of around 80 meters. External flushing can be used, but a small amount of oil leakage into the medium is also allowed in the event of a seal failure.
A regular centrifugal pump will do. Generally speaking, if the entry of other media is permitted, PLAN32+62 is recommended; the flushing medium should be diesel at room temperature, and back cooling should be achieved using low-pressure steam ； If other media are not allowed to enter, PLAN21+62 can be considered, that is, the pump outlet leads to the sealing chamber via an orifice plate and a cooler, with low-pressure steam being used for back cooling. The coolers in PLAN21 are cooled using demineralized water (as circulating water causes scaling); air-fin coolers can also be used, but flow conditions after the pump is stopped must be taken into account, otherwise the fluid will solidify.
Generally, it is a twin-screw pump – imported Bournsman models, or domestic Tianjin Industrial Pump models. I designed an asphalt pump with a 280-degree range last year
Whether a thermal insulation jacket is needed: gear pumps and rotor pumps are generally chosen, and several major imported brands can meet the requirements
With the 32 flushing scheme, it’s not only in the case of a mechanical seal failure that the flushing fluid enters the medium; dozens or even hundreds of liters of such fluid can enter per hour. Is that acceptable?
I’m not sure what the effect of this asphalt-based coolant will be on the fluidity of the asphalt
Positive displacement pumps can be used, such as rotary vane pumps and twin-screw pumps.
