Brief introduction

Twin screw pump is an important fluid conveying equipment. Because of its large volume flow, and it can transport medium with low viscosity without shearing, it is widely used in various industrial processes, also known as positive displacement twin screw pump, double gear pump and double shaft conveying pump.

Xinglong twin-screw pump is a positive displacement pump. The liquid is transported through a certain geometry cavity formed by sealing between the mating pairs (spiral sleeve and bushing). The spiral sleeves do not contact each other, so it has strong anti cavitation ability and can withstand dry operation within a certain time range. The material of pump overflow parts is determined according to the specific characteristics of the fluid materials transported.

Due to the highly integrated integral shaft and spiral sleeve with unique design, the material combination of pump components can be selected according to the actual conveying material conditions, so as to determine the best combination that allows high-pressure application. We provide complete rotating parts that have been dynamically balanced. In principle, the possible metal to metal contact in the pump is eliminated.

With the rotation of the pump, the meshing between the two spiral sleeves and the Bush forms a cavity. These chambers are filled with pumped fluid and are pushed from the suction side of the pump to the high pressure discharge side of the pump.

The radial force produced by high pressure makes the shaft components have great bending moment, so in the application of high pressure difference, special optimization design will be adopted, such as increasing the diameter of the shaft, reducing

Advantages

High pressure differential delivery capacity - involves optimum design of driving shaft, driven shaft, spiral sleeve and mechanical seal assembly

Compact structure - short design of key components

Reliability - the wear-resistant screw material allows the pump to withstand accidental contact bites due to solid particles

Non pulsating delivery - media will not be agitated, squeezed or sheared during pumping

Low vibration - even under the conditions of low inlet pressure, low viscosity medium and high-pressure transmission, the pump runs smoothly without vibration

Low noise - working principle virtually eliminates pressure fluctuations

Wide range of applications - high viscosity materials can be transported

Self absorption - with a certain degree of self absorption, usually there is no need to add another forced feeding device or equipment


For you to solve transport requirements include

Full series of standardization, the maximum flow can reach 600 m3 / h

Output pressure up to 40 bar

Different materials can be used for overflow metal parts, from tool steel to nickel / chromium steel, high acid resistant materials such as duplex stainless steel, Hastelloy and titanium alloy

The standard seal type is mechanical seal, and the cartridge mechanical seal is optional

Adjustable direction of import and export (to be indicated when ordering)


Strict quality standards and test procedures ensure that you get the best performance twin-screw pump. We continue to provide after-sales technical support (4008055600) to ensure the best performance under various service conditions.
