Canned Motor Centrifugal Chemical Pump No Leakage - China

Type of canned motor chemical pump

According to the different temperatures, pressures, particles, and viscosities of the media, chemical canned pumps can be divided into the following forms:

1 - Basic type (standard type)

The transmission medium temperature does not exceed 120 ℃, and the lift does not exceed 200m.

Other types of canned pumps are modifications and improvements based on the basic model.

2 - Reverse circulation type

This type of canned pump has the opposite direction of fluid flow for bearing lubrication, cooling, and motor cooling compared to the basic type.

The main characteristic of reverse circulation pumps is that they are not prone to cavitation, and are suitable for conveying easily vaporized liquids, sometimes referred to as easily vaporized pumps.

3 - High temperature type

The temperature of the conveying medium can be as high as 450 ℃.

Generally, a cooling water jacket is added outside the shielded motor and a cooling sleeve is added to the external circulation pipe to cool the high-temperature circulating liquid to reduce the temperature of the motor and bearing.

In situations where the power is not high, some manufacturers do not use coolant, but instead install heat dissipating fins outside the motor to adapt to the operating conditions.

The operating temperature should generally not exceed 400 ℃.

4 - High melting point type

A jacket is provided at the hydraulic end and the motor side of the pump, which can be filled with steam or high-temperature liquid to prevent crystallization of high melting point liquid.

The external circulation pipe of the pump should also be provided with thermal insulation (heating) jackets.

5 - High pressure type

The shell of the canned pump is a high-pressure container that allows the pump to withstand high system pressure.

In order to support the shield under internal high pressure, the stator coil itself can be used to withstand pressure.

It can also be made into a shielded pump operating under high temperature and pressure.

6 - Self priming type

The suction inlet of the pump is much higher than the center of the impeller.

After stopping the pump, when there is no liquid in the suction pipeline, the impeller and the enlarged pump chamber are always filled with liquid.

When restarting, the pump can operate without filling with water.

Self priming pumps are particularly suitable for extracting liquids from underground containers.

In addition, according to different methods, it can also be divided into submerged type, slurry type, high-pressure pipeline type, and various types of canned pumps specifically used for ships, nuclear power plants, and absorption refrigeration devices.

It can also be divided into vertical, horizontal, online, single stage, multi-level, and other different types.

7 - Multistage type

Equipped with multiple impellers, it is suitable for high lift fluid transportation, with a high lift of up to 600m.

8 - Mud type

Suitable for conveying liquids mixed with a large amount of mud.

According to the high-pressure liquid discharged from the impeller, it is used as a circulating cooling liquid to carry away heat.

According to the different media, circulating cooling is divided into three types: positive circulation, reverse circulation, and external circulation.
