Overview of JMZ Stainless Steel Self priming Pump

The stainless steel self-priming pumps JMZ and FMZ are assembled with a new type of mechanical seal, which is safe and explosion-proof, and does not leak all year round. They are suitable for transporting various types of alcohol, beverages, dairy products, pharmaceuticals, gasoline, solvent oil, syrup, etc. at -35 degrees+80 degrees (the suction range will be significantly reduced above 40 degrees). JMZ and FMZ stainless steel self-priming pumps have the characteristics of compact structure, easy operation, small volume, light weight, stable performance, no need for bottom valves, and no need for injection during start-up. After replacing 3-4 parts, JMZ and FMZ stainless steel self-priming pumps can be used to transport concentrated slurry, acid, alkali, salt and other liquids.

install

1. The pump can be laid on the foundation and the position of the foot bolts can be determined according to the 'Pump Appearance Installation Dimension Table'. But it's better to wait for the pump to arrive and then proceed with construction according to the size of the base.

2. The pump is installed on the foundation, and the level of the unit can be adjusted using shims. The level should also be checked with a spirit level, and the concentricity between the pump axis and the motor axis should be rechecked and adjusted. The difference between the outer circle, upper, lower, left, and right of the coupling should not exceed 0.15 millimeters using a knife edge ruler and a feeler gauge. The deviation between the end faces of the two couplings shall not exceed 0.2 millimeters.

3. Pumps should not bear the weight of pipelines, and the amount of pipelines should be supported by pipeline support equipment.

4. After installation, manually rotate the coupling to see if it is easy and flexible, and if there is any jamming phenomenon.

Disassembly and assembly

1 . Unscrew the four screws connecting the bearing body and pump body, and loosen the mechanical seal and pump cover at the same time.

2. Unscrew the impeller nut (turn right) to remove the impeller, key, and pump cover, and then remove the mechanical seal from the pump cover.

3. Use a slider to pull down the coupling, then remove the key and bearing end cover, and finally disassemble the shaft and bearing.

4. The assembly sequence of the pump should be reversed as described above.

When reinstalling the inlet coupling of the suction pump, please note that the water blocking valve should be facing forward to ensure a proper fit with the front of the water blocking valve and ensure self-priming effect (see the bottom right figure).

Installation of mechanical seals

1 . When replacing mechanical seals, attention should be paid to the specifications and models that match the original ones.

During the installation of mechanical seals, cleanliness should be maintained and the sealing components should not be knocked To prevent damage and destruction.

3 . When installing large and small sealing valves and dynamic and static rings, the surface should be coated with a layer of clean engine oil and transparent oil.

4. Install the static ring and large rubber ring into the pump cover, and then install them together on the shaft (note: the dynamic ring pin must be aligned with the drive hole of the impeller).

5. Push the ammunition seat and spring together to form a damaged assembly Using the spring seat surface as the force point, push it onto the main shaft, and the thrust should be compressed by the spring by 2-4mm before sliding on the shaft. If the spring is not yet compressed and can slide, it indicates that the fit between the dynamic ring and the main shaft is loose and the friction force is small. If the spring shrinks by more than 6mm and the dynamic and sealing rings still cannot slide on the shaft, it indicates that the fit is tight It should be checked whether the mechanical seal matches the original one.

Replace the shaft again

seal leakage

Insufficient spring pressure

Corrosion, wear, or scratches on the ends of the moving or stationary rings

Corrosion and deformation of the sealing ring of the 3 dynamic rings

4 foreign objects or medium crystallization affect the main movement of the moving ring

1. Adjust the compression amount of the spring or replace the spring

2. Repair or replace the dynamic or static ring

Replace the sealing ring with a new one

4. Remove foreign objects or crystals from the medium

motor overheating

1. High specific gravity or high temperature of the liquid

2. The mechanical seal spring is adjusted too tightly

3. Low voltage

4. Poor assembly quality, some parts experience friction or the motor and pump shaft are not concentric

1. Increase the motor size

2. Adjust the compression amount of the spring again

3. Increase voltage

4. Check the assembly quality and eliminate assembly faults
