NZJL

NZJL series slurry pump is a light type slurry pump, which is also a kind of horizontal centrifugal pump. The structure adopts a double shell structure, and the inner shell is an over-current vulnerable part that needs to be replaced periodically. According to the difference of working conditions, high-chromium metal or rubber can be selected. Compared with heavy-duty slurry pumps, this series of slurry pumps have lighter weight and high hydraulic efficiency in the same caliber, so the comprehensive use cost is low, and it has high economic efficiency in the condition of medium and low wear and tear, but it is not suitable for heavy And overweight and worn stations.

Product introduction

1. Product Overview

NZJL series slurry pump is a light type slurry pump, which is also a kind of horizontal centrifugal pump. The structure adopts a double shell structure, and the inner shell is an over-current vulnerable part that needs to be replaced periodically. According to the difference of working conditions, high-chromium metal or rubber can be selected. Compared with heavy-duty slurry pumps, this series of slurry pumps have lighter weight and high hydraulic efficiency in the same caliber, so the comprehensive use cost is low, and it has high economic efficiency in the condition of medium and low wear and tear, but it is not suitable for heavy And overweight and worn stations.

2. Product Features

1) The impeller is usually designed with 5 blades, the blades are relatively thin, the specific speed is relatively high, and the pump efficiency is high;

2) The overflow parts can be used in combination with high chromium and rubber materials according to the working conditions, which is flexible and diverse;

3) Adopting horizontal double shell design, it is relatively more convenient to install and maintain on site.

4) The bearing assembly adopts heavy-duty bearing design, adopts grease lubrication, and does not require an external oil station;

5) There are various types of shaft seals, and three types of packing seals, auxiliary impeller seals and mechanical seals can be selected. The three kinds of seals can be replaced without replacing other parts;

6) The gap between the impeller and the guard plate is designed with adjustable components, which can be easily adjusted during daily shutdown and maintenance;

7) The connection method between the pump and the motor can be belt, coupling, reducer, etc. according to the working conditions and site conditions;

8) This series of slurry pumps is generally not recommended to be used in series;

9) The outlet direction of the pump can be installed at eight angles to suit the pipeline installation on site.

3. Scope of application

1) This series of slurry pumps are light-duty slurry pumps, which are suitable for conveying low-concentration materials in the beneficiation process of non-ferrous and ferrous metal mines, such as flotation operations, plant backwater, etc.;

2) The recommended single-stage head is less than 40m, and the maximum conveying head can reach 60m;

3) It is recommended that the applicable weight concentration is not higher than 30%, and the median particle size is lower than -200 mesh;

4) When the rubber material flow part is selected, the temperature of the conveying slurry is recommended to not exceed 70℃. When the rubber material impeller is used, the maximum external circular velocity does not exceed 28m/s;

5) The pressure resistance value of the slurry pump does not exceed 1.725Mpa.

4. Specifications and flow range

The following table shows the best efficiency point of the NZJL series slurry pump at the corresponding speed. In actual application, the working range of each caliber pump can be adjusted by adjusting the speed of the slurry pump. Please contact us if it involves selection.
