2.5PB-11.5* 、 2.5PB-13.8* gear pumps

①   2.5PB-11.5*series gear pump
Model example: 2.5PB11.5S-R55S3
Displacement: 2.5 cm3/rev (displacement 2.5 cubic centimeters per revolution)
Rated pressure: 11.5MPa (about 115 bar)
Direction of rotation: clockwise (S)
Input interface: R55 pipe thread
Sealing material: Nitrile rubber (NBR)
Operating temperature: -20℃ to +80℃
Drive mode: motor drive or manual drive
Filtration accuracy: ≤40µm (standard configuration) or ≤30µm (optional)
Features
Medium pressure design: The rated pressure is 11.5MPa, which is suitable for medium and low pressure hydraulic systems, such as light construction machinery, agricultural machinery, etc.
Compact structure: small size, light weight, easy to install and maintain.
Low noise: optimize the gear tooth shape and meshing parameters to reduce operating noise.
Wear-resistant and reliable: the gears and pump bodies are made of high-quality materials, and the special heat treatment process has a long life span.

②  2.5PB-13.8*series gear pump
Model example: 2.5PB13.8/5.5 D-P55S3
Displacement: 2.5 cm3/rev (displacement 2.5 cubic centimeters per revolution)
Pressure parameters：
13.8 May represent the rated pressure (the unit needs to be confirmed, if it is bar, the pressure is lower, if it is MPa, the pressure is higher).
5.5 may represent power (kW) or another pressure parameter (such as outlet pressure).
Input interface: P55 flange (please refer to the manufacturer’s information for specific standards).
Sealing material: S3 (it may be nitrile rubber or other sealing material).
Other parameters: The meaning of each part of the model needs to be further confirmed (for example, D may represent the axis type or direction of rotation).
Features
Pressure flexibility: The pressure parameters may be adjusted according to the specific model, which is suitable for scenarios with different pressure requirements.
Flange connection: Provide a variety of flange connection methods to facilitate matching with different equipment.
Reliable sealing: high-quality sealing materials are used to reduce the risk of leakage.
Strong adaptability: support customized configuration to meet the needs of special working conditions.

SALAMI gear pumps are available with displacements from 1.4 cm3/rev to 99 cm3/rev (from 0.09 cu.in/rev to 6.03 cu.in/rev).
