4. Key Technical Parameters and Selection Guidelines
-
Pressure Grade: Rated pressure 14 MPa, maximum working pressure 17.5 MPa
-
Hydraulic Fluid Requirements: Recommended viscosity 20~400 cSt, operating temperature range -10℃~80℃
-
Mounting Method: ISO standard flange mounting, optional different port positions (Type A/B/D)
-
Noise Performance: 3~5 dB lower than ordinary vane pumps, SQPS model achieves further lower noise
-
Interchangeability: Partial models are interchangeable with Vickers V-series vane pumps with universal accessories
5. Application Notes
-
Single vane pumps can be used independently, or combined with other SQP series pumps to form double or triple pumps (e.g., SQP32, SQP43)
-
Model selection shall match the system flow demand, pressure grade and installation space
-
It is recommended to obtain the latest official product manual through official channels or authorized distributors to ensure parameter accuracy.
