5. Key Supplementary Instructions
-
Rotation Direction: Standard clockwise (viewed from shaft end); LH stands for counterclockwise
-
Outlet Port Position (viewed from pump cover end):
-
A: Opposite to inlet port
-
B: 90° counterclockwise from inlet port
-
C: Collinear with inlet port
-
D: 90° clockwise from inlet port
-
-
SQPS Series: Shares identical installation dimensions with SQP series, only equipped with pulse attenuation structure for lower noise
-
Installation Recommendations:
-
Adopt specified SAE standard flanges and bolts for flange mounting
-
Ensure base flatness ≤ 0.1mm for foot mounting
-
Shaft fit tolerance is recommended as H7/k6.
