TP 25-90/2 A-O-A-BQBE-DW1 Close-coupled single-stage volute pump with coaxial suction and discharge ports of the same diameter. The pump is of pull-out design. For example, the power head (motor, pump head, and impeller) can be disassembled for maintenance while the pump casing remains connected to the pipeline. The pump is equipped with an unbalanced rubber bellows seal. The shaft seal complies with DIN EN 12756 standard. An asynchronous motor with a cooling fan is installed on the pump.
Single-stage Pipeline Pump Model: TP 25-90/2 A-O-A-BQBE-DW1 Serial Number: 99221951
Application: Commercial Air Conditioning Single-stage Pipeline Pump
Basic Information
Model: TP 25 - 90 / 2 A - O - A - BQBE - DW1. The "TP" represents a certain series of pumps by Grundfos. "25" might refer to the nominal diameter of the pump's inlet and outlet (DN25), "90" could be related to the impeller diameter (90 mm perhaps), and "2" might indicate some other specific feature or parameter. The letters "A - O - A - BQBE - DW1" are likely codes for specific configurations, materials, or additional features of the pump2.
Serial Number: 99221951, which is a unique identifier for this particular pump within the manufacturer's production system, used for tracking, inventory management, and technical support.
Applicable Scenarios
It is suitable for commercial air - conditioning systems. In commercial air - conditioning applications, this pump is used to circulate the chilled or heated water in the system. It helps to maintain a stable temperature and ensure the proper functioning of the air - conditioning equipment by transporting the heat - transfer medium (water) through the pipes to the various components of the air - conditioning system, such as the evaporators and condensers.
Pump Characteristics6
Structure: It is a single - stage, close - coupled in - line centrifugal pump. The close - coupled design means that the pump and the motor are directly connected, which helps to reduce the overall size and installation space. The in - line design with coaxial suction and discharge ports of the same diameter allows for easy installation in the pipeline system. It can be mounted in the pipework or on a concrete foundation.
Maintenance - friendly Design: It adopts the top - pull - out principle. This means that the power head (including the motor, pump head, and impeller) can be disassembled for maintenance without disconnecting the pump casing from the pipeline, which greatly facilitates maintenance work and reduces the downtime of the system.
Sealing System: It is equipped with a corrosion - resistant, maintenance - free mechanical shaft seal, which ensures the tightness of the pump and prevents leakage of the pumped medium. The specific type of seal is an unbalanced rubber bellows seal, which complies with the DIN EN 12756 standard.
Materials: The neck rings and impeller are made of stainless steel, which provides good corrosion resistance and durability. The pump casing is likely to be made of cast iron, which is a common material for pump casings due to its good mechanical properties and cost - effectiveness.
Performance Parameters: The pump has a rated flow rate of 7.88 m³/h and a rated head of 7.93 m. It operates at a speed of 2865 rpm. These parameters are suitable for the specific requirements of commercial air - conditioning systems, providing the necessary water circulation and pressure to ensure the efficient operation of the air - conditioning equipment.
Electrical Equipment
It is fitted with a fixed - speed motor. For the specific model TP 25 - 90 / 2 A - O - A - BQBE - DW1, it may be equipped with a 2 - pole electric motor. The power supply is 415V, 3 - phase, 50Hz, and the motor power is 0.37kW. The motor is an asynchronous motor with a cooling fan, which helps to dissipate heat during operation and ensures the stable operation of the motor6.
