Product Features：

This stainless steel self-priming pump is assembled with mechanical seals, installed explosion-proof, and leak proof all year round. It is suitable for transporting various alcohols, beverages, dairy products, pharmaceuticals, gasoline, solvent oils, syrups, etc. at -35~+120 ℃.

This pump has the characteristics of compact structure, easy operation, small volume, light weight, stable performance, no need for bottom valve, and no need for injection when starting. After replacing 3-4 parts, the pump can be used to transport concentrated slurry, acid, alkali, salt and other liquids.

Installation and disassembly:

install

1. The pump can be laid and the position of the foot bolts can be determined according to the "Pump Outline Installation Dimension Table". But it is best to wait until the pump is delivered and proceed with construction according to the size of the base.
2. The self-priming magnetic 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 when checked with 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. The pump should not bear the weight of the pipeline, and the amount of pipeline 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 (right-handed) 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, bearing end cover, and finally disassemble the shaft and bearing.
4. The assembly sequence of the pump is reversed as described above.
5. When reinstalling the inlet coupling of the suction pump, please note that the water blocking valve should be facing forward to ensure a snug fit with the front of the water blocking valve and ensure self-priming effect.

Mechanical seal installation:

1. When replacing mechanical seals, attention should be paid to the specifications and models that match the original ones.
2. 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.
