with solidifying character under the normal temperature. It also applies to the site with heat-insulated requirement in the process technology and outdoors installation at very cold area.

This series of heat insulating gear pump belongs to external gear pump. The tooth from is composite formed by arc and sine curve. It could transfer many kinds of medium with steady output flow pressure. There are heat insulating jacket and inlet and outlet joint on the pump casing, so it could adopt the media, such as heat-conducting oil, steam, hot water and cold water to heat, keep warm and cooling the transferred medium and pump. When the speed should be reduced.
