Introduction: This product is efficient, energy-saving, with a long service life, light weight, reasonable structure, reliable operation, and convenient maintenance. It is suitable for industries such as power, metallurgy, coal, and building materials. The treatment medium is abrasive or corrosive slurry containing solid particles, with a solid-liquid mixed concentration of 45% for mortar and 60% for slurry. The medium temperature is ≤ 60 ° C. This type of pump can be used in multiple stages in series.

Pump body, pump cover, and flow passage components: This series of pumps is a horizontal, vertical, and double pump shell structure slurry pump. The pump body and cover are equipped with replaceable metal liners made of high chromium wear-resistant alloy material, which can be used until worn through, extending maintenance cycles and reducing operating costs. The outlet direction of the pump can be rotated and installed at 8 angles.

Bearing component: The bearing component of the pump adopts a cylindrical structure, which is convenient for adjusting the clearance between the impeller and the front guard plate. It can be removed as a whole during maintenance. The bearings are lubricated with grease.

Shaft seal (seal): The shaft seal types of pumps include packing seal, auxiliary impeller seal, and mechanical seal.

Transmission methods: V-belt transmission, elastic coupling transmission, gear reducer transmission, hydraulic coupling transmission, variable frequency drive device, thyristor speed control, etc. The V-belt transmission includes CL, CV, CR, ZL, ZV, and ZR transmissions.

Overall performance: The pump has a wide performance range, good cavitation performance, and high efficiency. Multi stage series connection technology can be used to meet long-distance transportation needs. There are various metals available for overcurrent components to choose from and increase their depth. Adopting multiple speeds and variants, the pump operates under optimal industrial conditions. Long service life, high operating efficiency, and able to meet various harsh conveying conditions.

Product features:

With the development and improvement of trash pump technology, combined with user feedback experience, modern fluid mechanics theory, modern mechanical theory, and computer software design technology are used; Our company has launched the EZJ series slurry pump, which has the characteristics of complete model, wide coverage of performance and working conditions, and convenient selection.

This series of products is designed as a single stage, single suction, centrifugal slurry pump. It is divided into horizontal (EZJ series) and vertical (EZJL series) according to its structural form. Horizontal pumps are divided into various specifications based on outlet diameter, including 350mm, 300mm, 250mm, 200mm, 150mm, 100mm, 80mm, 65mm, 50mm, 40mm, etc; Each pump with different specifications and calibers has different impeller diameters to choose from according to the head requirements.

This series of slurry pumps has innovation in hydraulic design, structural design, and other aspects. The flow passage components are made of self-developed wear-resistant high chromium alloy cast iron, which is highly efficient, energy-saving, long service life, light weight, reasonable structure, reliable operation, low vibration, low noise, and convenient maintenance.

The pump body adopts a double pump casing structure, which facilitates the replacement of overflow components; According to pressure requirements, the outer pump casing is made of ductile iron or gray cast iron, while the inner pump casing is made of high chromium wear-resistant white cast iron or cast steel.

Applicable scope:

The EZJ series slurry pump is mainly suitable for industrial industries such as power, metallurgy, coal, building materials, and chemical engineering. It is mainly used to transport abrasive slurries containing solid particles, such as processing concentrate and tailings in ore dressing plants, ash removal in power plants, transporting coal slurry and heavy medium coal in coal dressing plants, and transporting slurry in coastal river mining operations. The maximum weight concentration of the slurry it can handle is: 45% for mortar and 60% for mineral slurry; It can be run in series according to user needs.

Sealing form: The EZJ series slurry pump can adopt two types of shaft seals: auxiliary impeller and packing combination seal and mechanical seal.

(1) Auxiliary impeller power seal: The auxiliary impeller seal utilizes the pressure generated by the impeller and the series connected auxiliary impeller to seal, and the packing or lip seal serves as the parking seal. Single stage pumps or first stage pumps in series with multiple stages can adopt this sealing form when the positive pressure value at the pump inlet is not greater than 10% of the pump outlet pressure value. It can operate without shaft sealing water, without diluting the slurry, and has good sealing effects. But it will increase power consumption (usually by about 5% of the shaft power). Packing seal is a common form of shaft seal that is suitable for various working conditions and can be matched with special materials such as polytetrafluoroethylene packing and graphite packing. It can be used in corrosive or high-temperature conditions. It has the advantages of simple structure and convenient maintenance.

(2) Mechanical seal: Adopting internationally leading sealing technology, with good sealing effect. The containerized structure makes installation and replacement more convenient, and different structural forms adapt to different working conditions. The friction pair material is made of high hardness ceramic and alloy materials. The mechanical seal and sealing box are designed and matched in accordance with the flow state of the medium, thus possessing high wear resistance and seismic resistance, ensuring customer satisfaction in various harsh working conditions.
