NZJH

NZJH series slurry pump is a high-lift slurry pump, mainly used for long-distance transportation of ore slurry, such as long-distance transportation of tailings. Due to the limitation of the peripheral speed of the rubber flow parts, the flow parts of the NJZH slurry pump are made of metal without rubber flow parts. At present, the largest single-stage head of some pumps can reach 100m.

Product introduction

1. Product Overview

NZJH series slurry pump is a high-lift slurry pump, mainly used for long-distance transportation of ore slurry, such as long-distance transportation of tailings. Due to the limitation of the circumferential speed of the rubber flow parts, the flow parts of the NJZH slurry pump are made of metal without rubber flow parts. At present, the largest single-stage head of some pumps can reach 100m.

2. Product Features

1) The low specific speed design ensures that the pump has a single-stage high-lift delivery, while the impeller speed is relatively low, which reduces the wear of the flow parts and improves the service life of the flow parts;

2) 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;

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

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

5) This series of slurry pumps can be used in multiple stages in series;

6) The outlet direction of the pump can be installed at eight angles to suit the installation of on-site pipelines.

3. Scope of application

1) This series of slurry pumps are high-lift slurry pumps, which are suitable for tailings transportation, concentrate transportation, filter press feeding, etc.;

2) The recommended single-stage head is less than 90m;

3) It can be used in multiple stages in series, and the withstand voltage does not exceed 5.17Mpa;

4. Specifications and flow range

The following table shows the best efficiency point of the NZJH series slurry pump at the corresponding speed. In actual use, 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.
