Screw Pump Manufacturer: How to Choose the Right Screw Pump Manufacturer?

  Screw Pump Manufacturer: How to Choose the Right Screw Pump Manufacturer? In many industries, screw pumps have become indispensable due to their stable flow and high-efficiency fluid transport capabilities. Whether in oil, chemical, food processing, or wastewater treatment industries, screw pumps play an essential role. However, with numerous screw pump manufacturers in the market, how do you choose the right one? Today, let’s discuss how to select the right screw pump manufacturer based on multiple factors. 1. Advantages of Screw Pumps Handling High Viscosity Fluids Screw pumps are particularly suitable for handling high-viscosity fluids, such as oils, slurries, and thick liquids, without clogging, which makes them a preferred choice over traditional pumps. Stable Flow Thanks to the unique working principle of screw pumps, they provide stable and pulsation-free flow, making them ideal for precise metering and accurate fluid delivery. Handling Particulate Matter Screw pumps can e...

What’s a Self-Priming Pump? A Look at Its Uses and Selection Tips

 What’s a Self-Priming Pump? A Look at Its Uses and Selection Tips A friend recently asked me about self-priming pumps—what they are and where they’re used. Having worked in the industrial equipment field for years, I thought it’s worth sharing some insights on this practical yet somewhat niche piece of equipment. Let’s dive into what makes self-priming pumps special, their applications, and key tips for choosing the right one, with a nod to reliable brands like Shanghai Shangcheng Pump and Valve. What’s a Self-Priming Pump, and Why Is It Unique? In simple terms, a self-priming pump is a type of centrifugal pump that can “self-prime” without needing to be manually filled with liquid before each use. Just add a small amount of priming liquid to the pump body initially, and it’s good to go for life. Sounds pretty cool, right? The trick lies in its design: a liquid reservoir inside the pump allows it to mix air and liquid during startup, expelling air to create a vacuum that draws liq...

Self-Priming Pump Working Principle Explained — Easy for Beginners to Understand

 Self-Priming Pump Working Principle Explained — Easy for Beginners to Understand Self-priming pumps are widely used in agriculture, domestic water supply, municipal drainage, and various industrial applications. They are valued for their ability to start quickly and operate with minimal preparation. But how exactly do they work? This guide will break it down step-by-step in simple terms, so even beginners can understand. 1. How a Self-Priming Pump Works The “self-priming” feature comes from a clever internal design that allows the pump to automatically draw water without manually filling it every time. The process can be summarized as follows: Initial Priming When used for the first time, a certain amount of water is added into the pump casing to create the initial water seal. Impeller Rotation Once the motor starts, the impeller spins rapidly, mixing the water inside the casing with air from the suction line. Air Removal This water-air mixture is forced into a separation chamber....
