Overview
Product features: The G-series single screw pump is a new type of pump that works according to the principle of rotary meshing displacement. The transmission can be directly driven by a coupling or transmitted by a low-speed motor V-belt, gearbox, continuously variable transmission and other devices. Flow rate 0.8-150m3/h, pressure 0.4-1.2MPa.
Product Details
Product Name: G-Series Single Screw Pump
Product Introduction
The G-series single screw pump has been widely used in developed countries, and due to its excellent performance, its application scope in China has been rapidly expanding in recent years. Its characteristics are strong adaptability to the medium, stable flow rate, small pressure pulsation, and strong self-priming energy, which cannot be replaced by any other pump type. At present, our company's product has formed its own system with a pressure range of 0.4-1.2MPa, which can meet the different needs of users for single screw pumps.Product Features
The G-type series single screw pump is a new type of pump that works according to the principle of rotary meshing displacement. The transmission can be directly driven by a coupling, or transmitted by a low-speed motor V-belt, gearbox, continuously variable transmission and other devices. Flow rate 0.8-150m3/h, pressure 0.4-1.2MPa.There are many manufacturers of G-series single screw pumps on the market now, which one is good for G-series single screw pumps? Dadonghai Pump Industry specializes in producing G-series single screw pumpsSewage pumpThe models are very complete, welcome everyone to consult and purchase (pipeline pump bearings are heating up, pay attention here).
application
The G-series single screw pump is suitable for conveying industrial wastewater, domestic wastewater, and sludge and turbid water containing solid particles and short fibers. It is particularly used in oil-water separators, wheel bottom cleaning, oil-water, oil residue, oil contaminated water and other media transportation. It transports crude oil, mixtures of crude oil and water, coal gas and water mixtures, injects polymers into geological formations, various viscous slurries, emulsions, ointments, various viscous starches, concentrated distillers' grains, grain product residues, various sauces, slurries, solid matter slurries, cement mortar, lime slurry, coatings, paste spraying, solid particles, groundwater, slurry water in mines, various suspensions, oils, various colloid slurries, various adhesives. PVC for high viscosity ink and wallpaper Polymer plastic paste and various concentrations of pulp, short fiber slurry, coal water slurry transportation.Model Meaning
