High-efficiency, Energy-saving, Self-Balancing Multistage Pump
The highly efficient, energy-saving, self-balancing multi-stage centrifugal pump is a product independently developed by our company, Zhonglian Pump Industry, leveraging our proprietary intellectual property. It combines the features of the Omega series double-suction pumps and represents a cutting-edge design—a next-generation upgrade to conventional multi-stage pumps equipped with balance disc mechanisms. On February 21, 2014, the "Self-Balancing" pump trademark was officially registered under certificate number 11522619.
The high-lift submersible pump is short and convenient for transportation and installation, completely changing the situation where the entire submersible pump industry uses the QJ series for wells, filling a gap in the domestic submersible pump industry, and is an ideal tool for mine drainage and emergency rescue. High-lift submersible electric pumps are suitable for extracting groundwater from deep wells and mines, and can be used for emergency rescue in gold mines, silver mines, iron mines, and coal mines, as well as for construction site drainage. (Flow rate can reach 50 tons per hour, and lift can reach 1500 meters).
Slurry pumps are machines that increase the energy of a solid-liquid mixture using centrifugal force (rotation of the pump impeller), converting electrical energy into kinetic and potential energy of the medium. They are mainly used in mining, power plants, dredging, metallurgy, chemical, building materials, and petroleum industries.

With so many models of chemical pumps available, how do you choose the right one?
Chemical pumps come in a wide variety of models on the market—magnetic‑drive pumps, centrifugal pumps, diaphragm pumps, and more—each with an array of specifications that can be overwhelming. Many buyers focus solely on price, only to end up with equipment that stalls or wears out easily, fails to match the operating conditions, or consumes excessive energy, thereby needlessly driving up production costs. In fact, selecting a chemical pump doesn’t require memorizing every technical parameter; by focusing on three key considerations, you can effortlessly choose the right model for your application.

How should a horizontal multistage chemical pump be selected?
Many professionals in the chemical industry choose horizontal multistage pumps, but they often fall into a common trap: focusing solely on flow rate and head while overlooking the process medium, operating conditions, and equipment reliability. This leads to frequent wear, leaks, and shutdowns for repairs—resulting in both time and money wasted. In fact, selecting a chemical pump is quite straightforward:

How should you choose the price of a multistage chemical pump?
Many factory procurement and engineering professionals prioritize product price when selecting multistage chemical pumps. Pricing for these pumps is far from uniform, with a wide range that can span from several thousand yuan to hundreds of thousands of yuan. The final selling price largely depends on the pump model, materials used in construction, operating parameters, and any custom configurations. Below, we’ll provide a clear, easy-to-understand breakdown of market pricing for different types of multistage chemical pumps.
