Product type-description:
BMD type multistage pump is horizontal, double-shell, multistage, both ends supported centrifugal pump, core package has radial split (BB4 type) and axial split (BB3 type) two structures - can be pumped integral core package design, fast and easy maintenance; Impeller series or back-to-back arrangement, increase the shaft diameter of the rigid rotor rotor design, stable and reliable operation. Low cavitation pump can design the first stage double suction impeller structure.
BMRD(Z) type petrochemical process pump is a horizontal, double-shell, segmented, impeller axially arranged or back-to-back radially split, center-supported, multi-stage centrifugal pump designed in accordance with API 610 standard requirements and BB5 pump model.
The casing of this series of pumps has a radial guide vane structure, a center support structure, and an inlet and outlet arrangement that is above and above. The first and second stages of the impeller are designed using different design concepts. The first stage considers the cavitation performance of the pump, while the second stage considers the efficiency of the pump, making the entire pump have excellent cavitation performance and efficiency.
This series of pumps is designed strictly according to standard specifications in terms of pump support, bearing arrangement, reserved interfaces, cooling and flushing, cavity structure, material configuration, etc.
This series of pumps has excellent hydraulic performance, comprehensive type spectrum, high efficiency and high resistance to cavitation. It has been optimized based on a large amount of experimental data combined with hydraulic analysis software, making its hydraulic performance reach the leading level in the country.

1.Product sectional drawing:
Basic Structure Diagram of BMRD Standard Model.
1. Cone-shaped shaft extension design: When the shaft diameter is greater than 60mm, the product adopts a cone-shaped shaft extension design, which is conducive to the installation and removal of coupling, bearings, and seals.
2. Standard sealing configuration: The chamber size is designed in accordance with API 682 standard, and various forms of seal flush and cooling schemes can be configured. Alternatively, the configuration can be customized according to the user's requirements.
3. Good cavitation performance: the inlet impeller design ensures excellent cavitation performance.
4. Maintenance and inspection are convenient: The inner core adopts a pull-out structure, allowing for maintenance and inspection of the pump without moving the inlet and outlet pipelines.
5. Bearing Assembly: The pump body and impeller are both equipped with sealing rings, and the clearance and hardness difference between them meet the API610 standard, making it convenient to replace spare parts and prolonging the service life.
6. High-temperature design: In normal temperatures, the middle section cover is sealed with an "O-ring," and in high temperatures, it is designed with "metal face vs. metal face."
7. Various bearing selection forms: Depending on the power of the shaft and the speed, self-lubricating or forced lubrication bearing structures can be used.
8. Directional Setting: The cylinder is equipped with guide keys and positioning pins. When conveying high-temperature media, the pump extends towards the non-driving end without affecting the connection between the pump and the driving machine, ensuring reliable operation.

2. Standard sealing configuration: The chamber dimensions are designed in accordance with API 682 standard, and various types of seal flush and cooling schemes can be configured. Alternatively, the configuration can be customized according to the user's requirements.
3. Good cavitation performance: The suction-type first-stage double-suction impeller design provides excellent cavitation performance.
4. Maintenance and inspection are convenient: The inner core adopts a pull-out structure, allowing for maintenance and inspection of the pump without moving the inlet and outlet pipelines.
5. Bearing Assembly: The pump body and impeller are both equipped with sealing rings, and the clearance and hardness difference between them meet the API610 standard, making it convenient to replace spare parts and prolonging the service life.
6. High-temperature design: At normal temperatures, the middle section cover is sealed with an "O-ring," and at high temperatures, it is designed with "metal face vs. metal face."
7. The arrangement of inlet and outlet ports: The normal arrangement is an up-and-out structure, but it can also be arranged according to the user's requirements in other ways.
8. Directional Setting: The cylinder is equipped with guide keys and positioning pins. When conveying high-temperature media, the pump extends towards the non-driving end without affecting the connection between the pump and the driving machine, ensuring reliable operation.
9. Balanced Structure: The balance mechanism utilizes a drum-disc-drum coupling, effectively avoiding the "flashing" phenomenon while greatly increasing the service life and operational stability of the bearing.
10. Reliability assurance: The pump body, pump cover and other important parts are all manufactured by forging technology, and a 3mm corrosion allowance is guaranteed to ensure the safety and stability of the pump at the designed pressure.
