NZJ-Sequence Slurry Pumps
one. Uses and Functions:
NZJ-Collection slurry pumps are suited for pumping slurry with tough particles and in high density in industrial sectors as of metallurgy, mining, coal, energy era and constructing content. These pumps can also be applied multi-staged in collection. They are classified into 3 kinds: M. AH. HH.

The M. AH. HH kind slurry pumps are people of cantilever, horizontal and centrifugal slurry pumps, whose shafts can be sealed by packing seals or by centrifugal variety seals. The positions of the pump outlet can be positioned at an interval of 45° According to distinct needs, so eight distinct angles can be applied by rotation in set up.

The M. AH kind slurry pumps have pump bodies (volute liners, entrance and again liners) that consist of replaceable use-resistant steel liners or wear-resistant rubber liners, and impellers can also implement put on-resistant metal material or use-resistant rubber materials. The HH variety slurry pumps only utilize dress in-resistant metal materials as their pump bodies and impellers.

three. Structural Picture:
NZJ-Sequence slurry pumps are ideal for serious slurry situations with coarse particles and high competency.
3.one There are two varieties of content for wet parts (volute liners, front and back liners, impellers):
L Made of higher-chrome alloy material
L Made of very dress in-resistant rubber materials researched and created by CZPT firm.
Each of them can fulfill the activity of slurry pumping with higher effectiveness and lengthy services existence.
3.two Construction of shaft seals:
L Packing gland seals
L Strain-decreasing metallic gland seals
L Pressure-minimizing rubber gland seals
L CZPT seals.
NZJ Collection slurry pumps have two kinds of structural modes, which are the higher-chrome alloy one particular and the rubber dress in-resistance 1. The wet elements produced of either alloy or rubber can be combined up in procedure.

For illustration: A rubber volute liner and liners can be mixed with an alloy impeller in procedure, and a rubber impeller can be utilized together wit an alloy volute liner and liners.

4. Introduction of Sort Choice
When the type choice is conducted, the overall performance curve desk for obvious drinking water of a pump shall be referred to, and the coefficient of selection for the movement selected is as follows:

four.1 M, AH kind pumps
4.1. one For slurry of higher density and sturdy abrasiveness, the coefficient of circulation range will be forty-eighty%
4.one. two For slurry of medium density and medium abrasiveness, the coefficient of flow variety will be forty-100%
4.one. three For slurry of reduced density and reduced abrasiveness, the coefficient of circulation range will be forty-a hundred and twenty%.

four.two HH type pumps
four.2. one For slurry of medium density and strong abrasiveness, the coefficient of stream selection will be forty-eighty%
4.two. 2 For slurry of minimal density and robust abrasiveness, the coefficient of stream assortment will be forty-one hundred%
four.two. three For the maximum efficiency stage underneath a particular RPM situation, its corresponding flow fee will be one hundred%.
