  • Horizontal Slurry Pumps

    Horizontal slurry pumps are heavy-duty centrifugal pumps designed for handling abrasive and high-density slurries in mining, coal washing and industrial applications. This type of pump is widely used for continuous slurry transport with high efficiency and stable operation. Compared with vertical sump pumps, horizontal slurry pumps are easier to maintain and suitable for medium to high flow conditions. They are commonly used in mining, metallurgy, power plants and mineral processing industries.

  • 3 Common Causes of Slurry Pump Failure

    Because slurry pumps are the most extensive general-purpose mechanical equipment, they are used in various industries. Because the working conditions of these industries are not the same, the equipment failures under different application conditions are also different, but most of the failures are the same as the original equipment. The selection is directly related to the harsh working conditions after use, and the most common failures in alumina production are poor discharge and severe vibration. 1. No discharge or poor discharge during operation The failure or poor discharge of the slurry pump is a failure encountered in almost all industries that use…

  • What are the main features of a centrifugal pump?

    What is a centrifugal pump? A centrifugal pump is a machine designed to maneuver a fluid by means that of the transfer of motility energy from one or more than one driven rotor, known as impellers. Fluid enters the speedily rotating blade on its axis and is solid out by force on its circumference through the impeller’s vane tips. The action of the blade will increase the fluid’s rate and pressure and conjointly direct it towards the pump outlet. The pump casing is specially designed to constrict the fluid from the pump recess, direct it into the blade and so slow and manage the…

  • Slurry Pump: What It Is? How to Classify and Select It?

    Slurry pump is a large-scale centrifugal pump, which is mainly used to transport media containing abrasive solid particles. It is an indispensable general equipment in mining, chemical, coal and metal smelting industries. In the alumina production process, the slurry pump mainly transports the raw material slurry with high temperature, strong abrasiveness and large solid particle content, so it is also called the slurry pump. Most of the slurry pumps used in alumina production at home and abroad have experienced faults such as easy wear of overflow parts, short service life, rapid equipment vibration, and rapid decline in operating efficiency. These faults will…

  • How Do Sump Pumps Work

    What Is a Sump Pump? A sump pump is used in basements or crawlspaces to help keep the area dry and prevent it from flooding. Sump pumps are installed in specially constructed areas called sump pits. The typical sump pit measures between 15 and 18 inches across and around 2 feet deep. How Does a Sump Pump Work? When a sump pit fills with water, it reaches a set level on the pump, activating a switch and automatically turning on the sump pump. Most sump pumps use a centrifugal pump with an impeller to move water within the pit. As the impeller pushes the water…
