In the year 2023, we survived from Covid, and had a fast-developing year. This year, we had many old and new customers coming to our factory, after such a long time of restriction world widely, and finally we met face to face. With old customers, we talked about the current market conditions, their annual plans and goals. And after their visit, and see our factory changes, both from equipments and techniques, they are satisfied with all our improvements. Luckily we can work together, and support each other, to develop stronger and stronger in this market continually. For new customers,…

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…

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…

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…

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…

Slurry pump is a kind of centrifugal pump, used to transport the mixture of water and solid particles, such as slurry, ore, mud, etc. Slurry pump can be divided into vertical slurry pump and horizontal slurry pump. This article mainly talks about the characteristics, differences, advantages and disadvantages of vertical slurry pump and horizontal slurry pump. 1. Horizontal slurry pump Features Horizontal slurry pump adopts mechanical seal, most of the parts can be interchangeable, increasing the service life. Simple operation, easy maintenance; in addition, horizontal slurry pump operation noise is low, vibration is small; robust, long service life, spacious…

With summer comes beautiful weather, flowers, and of course rain; lots and lots of rain. Unfortunately, all this water has to go somewhere, and most times, it finds its way into your basement and causes a nightmare of flooding. With the proper sump pump, you can prevent this ordeal from occurring and save yourself thousands of dollars in repairs that come from flood damage. While it may seem so simple to just go out and buy the first one you see, we recommend taking some time and seeing what each model can offer. Whether you already have a sump…

Are you constantly making Band-Aid fixes, or do you want to start converting your site to low-maintenance? When investing in new pumps and equipment, remember that the upfront cost is only 10% of the total investment. That’s why we understand the importance of choosing the perfect slurry pump, so at Longteng Machinery, we are committed to finding you the best solution for your site. We recommend peristaltic hose pumps and slurry pumps for low maintenance locations. Peristaltic hose pumps are low-maintenance because they have only one wearing part, the hose, while slurry pumps are highly wear-resistant, resulting in less…

Self-priming pumps are a specific type of liquid pump. They are designed for fluid movement and transfer which results in increased efficiencies in many pumping applications. Why consider a self-priming pump? Self-priming pumps can be mounted above the liquid source at ground level, therefore, less infrastructure and equipment is required during setup. Centrifugal, Helical Rotor and Magnetic Drive Pumps are self-priming, and multi-industry ready. DID YOU KNOW? These pumps are commonly used to encourage and raise liquids from a high to low level and can pump at high volumes or adjust their flow rates! How self-priming pumps work Self-priming pumps are specifically engineered centrifugal…

To maintain optimal pump performance for longer, it is important to service your pump regularly, and ensure it’s accessible for regular servicing including: removing sections of pipe work, maintaining sufficient cooling around the pump and having the required space for lifting equipment. Centrifugal pump installation: Centrifugal pumps may need spacer couplings. These couplings are essentially a cylindrical shaped coupling with a removable section, suitable for end suction back pull out pumps. These spacers allow enough space between the pumps mechanical seals when doing maintenance to avoid moving either the pump body or the driver. Essentially this means …  prior to installation,…
