TXVA pumps | Variable displacement

Product catalog summary

Characteristics
The document describes the TXVA series of variable displacement piston pumps with load sensing control, specifically the SAE version. Key characteristics include:

Displacement options: 4.60 cu.in/rev (75 cc/rev) and 5.60 cu.in/rev (92 cc/rev).
Direction of rotation: Clockwise (CW) and Counterclockwise (CCW).
Flange options: SAE C with 2 bolts (C1) and 4 bolts (C2).
Shaft end options: Splined (SAE J744 14T 12/24 DP) and Keyed (SAE J744 Ø1 1/4" UNF 2A).
Port options: UNF Threaded and BSP Threaded for inlet and outlet.
