The G series single screw pump is a new pump design that operates on the principle of counter-rotation of interacting elements with positive displacement. Its main operating components include an eccentric screw (rotor) and a fixed bushing (stator). The unique geometric configuration of these two components creates separate, sealed chambers.
The G series single screw pump is a new pump design that operates on the principle of counter-rotation of interacting elements with positive displacement. Its main operating components include an eccentric screw (rotor) and a fixed bushing (stator). The unique geometric configuration of these two components creates separate, sealed chambers. The product is transported evenly in the axial direction, characterized by low internal flow velocity, minimal noise, constant volume and stable pressure. As a result, no vortex formation or turbulence occurs, which ensures the preservation of the original structure of the product. The stator, made of various elastic materials, allows the Yangguang screw pump to pump highly viscous liquids and media containing suspended solids or fibrous substances with capabilities superior to those of traditional types of pumps. Its consumption is directly proportional to the rotation speed.
Continuous, low pulsation flow, unaffected by pressure or viscosity fluctuations.
Wide range of applications, the ability to pump both bulk and non-bulk materials.
During pumping, the medium remains unchanged, without compression or shear.
High efficiency with flow rate proportional to rotation speed, allowing flow control via frequency control.
Most liquids can be pumped with minimal turbulence and pulsation.
Easy maintenance and repair combined with high pressure supply capability.
