Horizontal pump base and its scope of application

Horizontal pump base and its scope of application
MIMO Split Case Water Pump

Common base

advantage:

It has a wide range of applications, especially suitable for small pump sets without foundation (mobile) pump sets and supporting low-voltage motors.

Disadvantages:

1. When the pump set is large, it is inconvenient to manufacture, transport, store and install the base;

2. Due to the delivery date and transportation costs of larger motors, it is often necessary to ship the motors directly to users from the motor manufacturer. At this time, if the motor mounting holes are processed in advance on the base, the motor mounting holes and the mounting holes on the base often cannot be aligned due to the manufacturing errors of the motor and the base, and need to be repaired on site;

3. If the user needs to replace the pump head or motor later, the base needs to be replaced or modified as a whole, which is costly and workload;

4. Gray cast iron has good damping (shock) performance and good corrosion resistance, and is suitable for producing bases. However, when the pump set is large, the production difficulty of the cast base increases, or even cannot be produced.
Multistage Water Pump

Pump with base, motor without base

advantage:

It is suitable for larger motors and saves the cost of the base.

Disadvantages:

1. Due to the height difference between the pump base and the motor foot mounting surface, the foundation needs to be made unequal height, which will make it difficult to guarantee the position accuracy of the reserved anchor bolt holes and increase the difficulty of foundation irrigation;

2. The grouting may block the air passage at the bottom of the motor and affect the ventilation and heat dissipation of the motor;

3. When the user replaces the motor in the future, the motor foundation often needs to be re-poured.

Pump and motor each have independent base

Disadvantages:

It is not suitable for small pump sets without foundation (mobile) pump sets and supporting low-voltage motors.

advantage:

1. When the pump set is large, the manufacture, transportation, storage and installation of the base are more convenient;

2. Due to the delivery date and transportation costs of larger motors, it is often necessary to ship the motors directly to users from the motor manufacturer. At this time, the mounting holes on the base of the motor that have been processed by the pump manufacturer in advance are easy to align with the mounting holes on the motor, without on-site repair;

3. If the user needs to replace the pump head or motor in the future, he only needs to replace or modify the respective base, which is less costly and workload;

4. Gray cast iron has good damping (shock) performance and good corrosion resistance, and is suitable for producing bases. The independent base is relatively small in size and convenient for casting.
