(1) Wide range of pressure and flow, flow range 0.2 ~ 318m3/h_ working pressure up to 4.0MPa; (2) A wide range of types and viscosity of liquids transported; (3) because the inertia force of the rotary parts in the pump is low, it can use a high speed; (4) Good aspiration and self-imbibition ability; (5) uniform and continuous flow, small vibration, low noise; (6) Compared with other rotary pumps, the gas and dirt into the less sensitive. (7) Solid structure, easy installation and maintenance; (8) three screw pump, self-priming; (9) Due to the general assembly series of parts have a variety of structures, can be used for horizontal, flange and vertical installation; (10) According to the needs of the conveying medium can also provide heating or cooling structure;Flow Q (max): 318 m3/h Differential pressure △P (max): ~4.0MPa Speed (max): 3400r/min Working temperature t (max): 150℃ Medium viscosity: 3~3750cStThe insulated screw pump (insulated draining pump) produced by our company is mainly used for conveying high viscosity and high temperature lubricating liquid. Often used in asphalt, heavy fuel oil, heavy gear oil and other media transportation. The hot carrier can be steam, hot oil and hot water, and the cold carrier can be gas or liquid. This product is widely used in petroleum, chemical industry, metallurgy, machinery, electrical, chemical fiber, glass, highway and other industries.
