I. Overview

The MC pump is a horizontal multistage centrifugal pump with radial split and segmented structure. It is mainly used for transporting clean or slightly contaminated liquids, as well as low or high-temperature liquids. Typically applied in water supply systems, thermal power plants, pipeline pressurization, and refrigeration engineering, among others. When transporting media at high pressure, consider the working temperature of the medium and the material of the pump. Flow rate: ~1000 m3/h, Head: ~1600 m, Temperature: -80~+180°C, Pressure: ~150 bar


II. Usage

Primarily used for:

Water supply systems, thermal power plants, pipeline boosting, refrigeration engineering, oil refineries, petrochemical industry, etc.

IV. Design Features

Each model of MC type multi-stage centrifugal pump is designed with standardized dimensions for all its components, thereby reducing the number of spare parts in stock.

 

Mid-section housing: Sealed with an O-ring between the mid-sections and connected together externally with bolts.

 

Entrance and exit sections: Typically, foot supports are used for the entrance and exit sections.

When the temperature of the fluid being conveyed is t > 150°C, pumps of MC80 specification and above are the central support.

At temperatures above 110°C, pumps of MC150 and above specifications serve as central supports.

 

Position of inlet and outlet pipes: Generally, the outlet pipe faces upwards, and the inlet pipe faces to the right (when viewed from the drive end).

The position of the import/export pipes can be changed freely, and additional outlet pipes for other uses can be set up on the object.

 

Hydraulic model and axial force balance: Each specification comes with two different impellers/ guide vanes (hydraulic models). This results in a larger high-efficiency operating area. The replaceable mouth ring serves as a seal between the impeller and the housing, with the axial force generated by each stage of the impeller balanced by the hydraulic balancing device. If a balancing drum assembly is used to balance the axial force, the residual axial force is absorbed by the bearings.

 

Bearings and Lubrication: Pumps are lubricated with light oil.

 

Axial Seal: Packing seal or mechanical seal.

 

Material: The corrosion-resistant materials used by Flying Pump Industry fully meet the requirements of the aforementioned media. When placing an order, please provide detailed information about the medium to be conveyed.


Section 6: Features and Benefits

1. Shell Support

• Under large-scale and high-temperature conditions, a central support can be used.

2. Pipe End

• Larger inlet bore optimizes the flow condition for imports

Achieve a reduction in noise levels by lowering the flow rate within the channels

• Allow higher force and torque

3. Impeller

Modular hydraulics for enhanced efficiency across a wider operational range for pumps.

• Lower NPSHR (Net Positive Suction Head Required) at the first stage, some pump models can be equipped with a first-stage double-suction impeller.

4. Axle

• The rigid shaft design results in a critical speed higher than the operating speed, with less shaft deflection.

• The worn area is protected

Ring Gag

Maintain high efficiency throughout the usage period.

Low maintenance costs, high reliability, and short downtime.

Axial Thrust Balance System and Bearings

The design of the balanced drum and thrust bearing ensures that the pump maintains a long service life even under extreme operating conditions.

• In cases of frequent start and stop operations, the balanced disc with thrust protection device can be used.

• Radial sliding bearing is an optional design

7. O-ring

• The housing is sealed with a restricted O-ring, thus the housing seal is unaffected by rapid temperature changes and high pressure.

8. Sealed Enclosure

• Sufficient cooling

Easy-to-install water-cooled cavity structure
