NZJA(AH)

NZJAH series slurry pump is a general-purpose heavy-duty slurry pump, which is a kind of horizontal centrifugal pump. The structure adopts horizontal double shells, in which the inner shell is an over-current vulnerable part, which needs to be replaced periodically. High-chromium metal or rubber materials can be selected. The product is relatively simple in structure, reliable in operation, and long in service life of the flow parts, especially suitable for medium and high concentration slurry transportation.

Product introduction

1. Product overview

NZJAH series slurry pump is a general-purpose heavy-duty slurry pump, which is a kind of horizontal centrifugal pump. The structure adopts horizontal double shells, in which the inner shell is an over-current vulnerable part, which needs to be replaced periodically. High-chromium metal or rubber materials can be selected. The product is relatively simple in structure, reliable in operation, and long in service life of the flow parts, especially suitable for medium and high concentration slurry transportation.

The NZJA series slurry pump is a heavy-duty slurry pump optimized and modified on the basis of the NZJAH series slurry pump. The jacket of the NZJAH series slurry pump is optimized to further enhance the service life of the jacket and front and rear guard plates. The lining flow parts can only be made of rubber material. Under heavy wear conditions, the wear resistance of the lining flow parts is better than that of the NZJAH series slurry pump.

2. Product features

1) The impeller is usually designed with 5 blades, and the impeller and other flow parts are designed with heavy wear, and the service life of the flow parts is long;

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 a heavy-duty bearing design, grease lubrication, no external oil station is required, only regular maintenance and grease can be required, the bearing assembly can be optionally equipped with additional temperature measurement components, which is convenient for on-site automatic control;

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 types 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 can be used in multiple stages in series to meet the needs of high-lift stations;

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 general-purpose heavy-duty slurry pumps, which can be applied to various types of slurry transportation in the grinding and beneficiation process of non-ferrous and ferrous metal mines, with a wide range of applications;

2) The recommended single-stage head is less than 60m, and the maximum conveying head can reach 80m;

3) It is recommended that the applicable weight concentration is 60%, and more than 60% of the pulp requires evaluation and related rheological tests;

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 rubber slurry pump does not exceed 1.4Mpa, and the pressure resistance value of metal pump does not exceed 2.1Mpa.

4. Specifications and flow range

The following table shows the best efficiency point of the NZJA/AH 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. .
