Characteristics And Classification Applications Of Sanitary Rotary Vane Pumps

Sanitary Rotary Lobe Pump, including a pump body, a pump cover, an electric motor with an output shaft, a pump shaft, a bearing seat, an impeller, a mechanical seal and a mechanical seal gland installed in the pump body, characterized in that it also includes a clamp-type coupling arranged between the motor output shaft and the pump shaft, and a guide bearing installed on the bearing seat to assist in supporting the pump shaft; the clamp-type coupling is rigidly connected to the motor output shaft and the pump shaft respectively, and a space distance is left between the motor output shaft and the pump shaft to facilitate the installation and removal of the mechanical seal and the mechanical seal gland. When repairing or replacing the mechanical seal, there is no need to remove the motor and the pump cover.

Classification of sanitary rotary vane pumps
1. Non-self-priming single-stage horizontal end-suction centrifugal pump, axial inlet and radial outlet, adopts a back-pull structure, and maintenance does not require the removal of the pump body and pipeline. Advantages: stable operation, stable structure, convenient maintenance, low noise, installation dimensions meet ISO2858 standards
2. Single-stage vertical pipeline circulation pump, the pump inlet and outlet are on the same straight line at the bottom of the pump. The product is designed to be disassembled and assembled with the top pulled out, which can be repaired without affecting the pipeline system. Advantages: compact structure, easy maintenance, low noise, optional cast iron or stainless steel impeller.
The detachable pipeline pump is designed to be disassembled and assembled with the motor end pulled out, which can be repaired without affecting the pipeline system. When this product is used to transport water, it can be used in the following locations: main circulation pump, pump in mixed loop, boiler mixed flow pump, gas refrigerator pump, partial flow filter pump, constant pressure system pump, domestic hot water circulation.

Features of sanitary rotary vane pump
1. The pump has a compact structure, small size and beautiful appearance. Its vertical structure has a low center of gravity and the center of gravity coincides with the center of the pump foot, which enhances the operating stability and life of the pump.
2. Easy to install. The inlet and outlet diameters are the same and on the same center line, and can be directly installed in any part of the pipeline like a valve. The motor plus the rain cover can be placed outdoors for use. The pump is equipped with a mounting foot to ensure stable installation of the pump.
3. Smooth operation, low noise, and high concentricity. The motor uses low-noise bearings and is equipped with a non-stop refueling device. The pump impeller has an extremely good dynamic and static balance, runs without vibration, and improves the use environment.
4. No leakage. The shaft seal uses a corrosion-resistant hard alloy mechanical seal, which solves the serious leakage problem of the centrifugal pump packing seal, extends the service life, and ensures that the operation site is clean and tidy.
5. Easy maintenance. No need to disassemble the pipeline, just remove the pump cover nut, take out the motor and transmission components for inspection and maintenance.
6. According to the on-site use conditions, the pump can be installed vertically, horizontally, and in multiple ways. According to the flow head requirements, the parallel and series methods are used to increase the required flow head.

Application of sanitary rotary vane pumps
Domestic water, industrial water, cooling system water, and cold and hot water for regional heating systems; chemical, pharmaceutical, food processing and other industries. Vertical hot water pumps and horizontal hot water pumps are suitable for heating of residential buildings and hot water boosting, circulation, and transportation in civil and enterprise units with heating systems, such as telephone, thermal power station, waste heat, utilization, metallurgy, chemical industry, textile, wood processing, papermaking and other industrial boilers with high-temperature hot water, and the use temperature is below 120℃. Item Statistics

Sanitary rotary vane pumps can effectively solve the problem of hot and cold hot water caused by insufficient water pressure due to the small height difference of the rooftop of solar water heaters. This pump is suitable for 0℃-100℃ cold/hot water boosting, and can realize automatic start and stop according to the change of water flow, which is more energy-saving.

Sanitary rotary vane pumps are the best solution for small domestic water boosting in residences, villas, baths, hotels, etc. It can realize boosting from the ground, and also supports downward boosting of water supply from roof water tanks. With sanitary rotary vane pumps, you will no longer worry about problems such as insufficient water pressure and unstable water flow caused by insufficient water pressure in domestic water.
