Product overview
The G-type gear screw pump is a new pump model that operates on the principle of positive displacement with rotary gearing. The main operating components are the eccentric screw (rotor) and the stationary bushing (stator). The special geometric shape of these two components creates separate sealed chambers. The medium moves uniformly in the axial direction with low internal flow velocity, low noise, constant volume and stable pressure. This eliminates the formation of turbulence and mixing, which allows the original structure of the medium to be preserved. Because the stator is made of various elastic materials, Yangguang screw pumps have unique characteristics for pumping high-viscosity liquids, media with suspended solids or fibrous materials, which are not available for most traditional types of pumps. The pump capacity is directly proportional to the rotation speed.
Product benefits
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.

Note:
The above operating parameters are test data obtained at ambient temperature using pure water.
Operating parameters will vary for different environments and rotation speeds. Flow rate is proportional to concentration and viscosity and directly proportional to rotation speed.
Users should select the pump type based on operating requirements, fluid characteristics and selection principles, or consult customer service to determine the appropriate pump type.
