Product catalog summary

Overview of Sine Pump Design and Functionality

The sine pump features a simple and efficient construction with few components, embodying the principle that high-quality products maintain minimal complexity. Its impeller is uniquely shaped with sine wave curves, enabling the formation of cavities during rotation that facilitate the pushing or releasing of fluid products.

Operating Principle

The impeller's sine wave shape creates four cavities per rotation as it passes through the lining space. These cavities are divided by a control panel into suction and discharge chambers, ensuring proper pressure differentials at the inlet and outlet. The control panel also serves to forcibly lubricate the pump bearing using the product itself.

Performance Characteristics

High Efficiency: The sine pump delivers excellent efficiency, especially suited for handling high-viscosity fluids.
Super Low Shear Feeding: It safely transports products containing large amounts of solids or fragile materials without damage.
Viscosity Handling: Capable of pumping fluids with viscosities up to 4,000,000 centipoise (cps), reaching the limits of flow capability.
Pulse-Free and Stable Flow: The pump provides smooth, non-pulsating flow with precise volumetric adjustment, avoiding interference or vibration. This stability supports uniform dosing by filling machines.

Structural Features

Unlike traditional pumps using rotors, planetary gears, or pistons, the sine pump employs specially manufactured vanes shaped like two sine curves. These vanes operate in conjunction with a movable control panel and a fixed lining to form a unique volumetric pumping mechanism that achieves ultra-low shear fluid handling.

Pressure and Backpressure Handling

The pump maintains stable operation even under backpressure conditions up to 10 bar (e.g., water pumping), with no observable pressure gauge fluctuations, indicating consistent flow without pulsation.

Variants of Sine Pumps

Gear constant speed ratio sine pump
Step-less variator sine pump
Frequency controlling movable sine pump
V type inlet sine pump

Summary

The sine pump is a specialized volumetric pump designed for efficient, gentle, and stable transport of high-viscosity and delicate products. Its simple yet innovative design ensures minimal shear, no pulsation, and reliable lubrication, making it an excellent choice for demanding industrial applications.

正弦泵 SINE PUMP Function Principle 功能原理 Any exquisite product or good functional product has a simple structure---including few components….sine pump is not an exception. 任何精品或功能良好的产品均具有简约的构造--又包括少数组件……正弦泵亦不例外。 The sine wave shape of impeller means a cavity can be formed at every rotation (4 cavities can be formed every passing the lining space). This operation can "push" or "release" flowing products. The pump cavity is divided into suction chamber and extraction chamber by control panel to ensure pressure tolerances at exit and entrance. Meanwhile, control panel plays another important role to lubricate the pump bearing by product in compulsion. 叶轮的正弦波造型意味着每次转动均可形成一个腔室(每次经过衬套空间时可发生4次）。通过该运动，可“推动”或“排放” 流动产品。控制刮板将泵腔分为吸入腔室和排出腔室，保证进出口的压差。同时，控制刮板也发挥着另一项重要作用，即通过产品对泵轴套进行强制润滑。正弦泵-效率卓越，是高粘度，超低剪切输送的有效选择超低剪切输送即使含有大量固体物质和易碎产品，仍可安全无 V型进料型正弦泵 V type inlet sine pump High viscosity performance reaches the limit of flowing capability Can reach 4,000,000cps No pulse, stable feeding Flow cubage adjustment precisely, without interference and shock.
