product name: ZX series horizontal self-priming pump
Caliber (import / export): 50 ~ 200mm
flow: 6.3 ~ 400m3 / h
Head: 5 ~ 132m

Product Overview:
ZX series pumps are horizontal self-priming centrifugal pumps. This type of self-priming pump is compared with other types of self-priming centrifugal pumps, because the pump itself has no check valve, the structure is the simplest, the most reliable work, long trouble-free working time, maintenance, easy use, small size, light weight, high efficiency Special considerations have been made in the design. Compared with pumps of the same caliber, the displacement is large and the performance is high.
ZX pumps are more effective as emergency pumps in industrial and agricultural production, emergency rescue, such as drainage and fire fighting. ZX self - priming pumps are widely used in petroleum, chemical, metallurgy, machinery, chemical fiber, food, energy, transportation and other industrial sectors in urban water supply. They can also be used for agricultural drainage and sprinkler irrigation. For transporting water or other liquids with a viscosity less than 5 ° E and a temperature below 80 ° C similar to water.
 
Product use:
Suitable for urban environmental protection, construction, fire protection, chemical, pharmaceutical, dye printing, brewing, electricity, electroplating, papermaking, petroleum, mining, equipment cooling, oil tanker unloading, etc.
Applicable to clean water, seawater, chemical media liquids with acidity and alkalinity, and slurries with general paste (media viscosity ≤100 centipoise, solid content up to 30%).
Equipped with a rocker-type sprinkler, it can flush water into the air and spray into small raindrops for spraying. It is a good tool for pesticides, nurseries, orchards, and tea gardens.
It can be used with any type and specification of filter press. It is the most ideal pump for feeding slurry to the filter.
Technical parameters:
Flow: 6.3 ~ 400m3 / h;
Head: 5 ~ 132m;
Speed: 2900, 1450r / min;
Power: 0.55 ~ 110KW;
Inlet diameter: 50 ~ 200mm;
Maximum working pressure: 1.6Mpa.

5. Maintenance and disassembly:

The pump is characterized by simple and reliable structure and durability. Under normal circumstances, the pump generally does not need to be disassembled and maintained frequently. When the fault is found, it can be eliminated at any time.

1.There are several main parts to pay attention to when maintaining the pump:
a. Rolling bearings: After the pump has been running for a long time, the bearings must be replaced to a certain extent.
b. Front seal ring and rear seal ring: When the seal ring is worn to a certain extent, it must be replaced.
c. Mechanical seal: Generally, the mechanical seal should not be disassembled and inspected without leakage. If there is a serious leak at the leak at the lower end of the bearing body, the mechanical seal should be disassembled and inspected. When assembling and disassembling the mechanical seal, you must handle it gently, pay attention to the cleanness of the mating surface, protect the mirror surfaces of the static ring and the moving ring, and do not knock or collide. Leakage due to mechanical seals is mainly caused by friction on the mirror. The repair method can grind the frictional end surface to restore the mirror surface. Another reason for the mechanical seal to leak is that the "O" 'rubber seal (or cushion) is improperly installed or deformed. In this case, you need to adjust or replace the "O'-ring" for reassembly.
2. Pump disassembly sequence:
a. Remove the motor or disconnect the coupling.
b. Remove the bearing body assembly, check the radial clearance between the impeller and the front ring, and check whether the impeller nut is loose.
c. Remove the impeller nut, pull out the impeller, and check the radial clearance between the impeller and the rear seal ring.
d. Loosen the settling nails of the mechanical seal, pull out the moving ring part of the mechanical seal, check the fit of the end faces of the dynamic and static rings, and check the seal of the "O" -shaped seal (or cushion).
e. Unscrew the set nut of the coupling and pull out the coupling.
f. Remove the bearing end cap and remove the pump shaft and bearing.
g. Assemble in reverse order during installation.
6. Faults and troubleshooting:

malfunction
cause
Method of exclusion
Water pump
1. No or insufficient fluid is stored in the pump casing
2. Leakage in the suction line
3.Speed is too low
