High viscosity gear pumpis an internal gear pump. Due to its unique structure, the conveyed medium has a relatively high viscosity. Many customers don’t know how many meters the self-priming capacity of high viscosity gear oil pumps is. The most important thing above is the crescent plate and the inside and outside. With the gears, the self-priming ability can be reflected. The normal high-viscosity gear pump can transport oil-type media, the self-priming capacity can reach 5 meters, the self-priming capacity of medium-viscosity media is 3 meters, and the self-priming capacity of high-viscosity media 1 -2 meters, different occasions, different viscosity high viscosity gear pump self-priming ability is also different. Stainless steel high viscosity gear pump use packing seals for high-temperature, high-viscosity and corrosive media. When the inner-ring high-viscosity pump transports easily crystallized materials, the front cover and pump body can be designed with thermal insulation jackets, which can be melted by steam during operation. Seen from the extending end of the main shaft toward the pump, it rotates clockwise.
