Detailed Explanation of Submersible Pump Mechanical Seal Models And Sizes

1. Definition and function of mechanical seal of submersible pump

The mechanical seal of submersible pump refers to the separation of rotating shaft from fixed components to ensure the sealing performance of submersible pump. Mechanical seals are often used to seal high-speed, high-pressure, high-temperature, toxic and harmful media to ensure the normal operation of equipment.

2. Common mechanical seal models and sizes

1. MG1 type mechanical seal

MG1 type mechanical seal is one of the most commonly used mechanical seals. Its size is Φ12 ~ Φ100, suitable for sealing of various pumps. This mechanical seal adopts a single-end face sealing structure, with the advantages of stable performance and reliable sealing.

2. MG12 type mechanical seal

MG12 type mechanical seal is a double-end face mechanical seal, suitable for sealing of various high-speed pumps. Its size is Φ20 ~ Φ100, with good sealing and long service life.

3. BZ type mechanical seal

BZ type mechanical seal is suitable for sealing of various pump equipment. Its size is Φ12 ~ Φ100, adopts a single-end face mechanical seal structure, with good sealing performance and long service life.

4. 108-type mechanical seal

The size of 108-type mechanical seal is Φ16 ~ Φ60, which is suitable for sealing various conventional pumps and chemical pumps. The mechanical seal adopts a single-end mechanical seal structure, which has the characteristics of simple structure and easy use.

III. How to choose a mechanical seal

The following aspects should be considered when choosing a mechanical seal:

1. Determine the properties and temperature of the medium

Select a suitable mechanical seal according to the properties of the medium such as acidity, alkali, viscosity, corrosiveness, and temperature.

2. Determine the speed and pressure

Select a suitable mechanical seal according to the speed and pressure of the equipment.

3. Determine the size and specifications

Select a suitable mechanical seal according to the shaft diameter, pump body specifications, sealing gap and other factors of the equipment.

In summary, the mechanical seal of the submersible pump is a key component to ensure the sealing performance of the submersible pump. Choosing a suitable mechanical seal can ensure the normal operation of the equipment. When choosing a mechanical seal, factors such as the properties of the medium, speed and pressure, as well as the size and specifications of the mechanical seal should be considered to select a suitable mechanical seal.
