TECHNICAL FEATURE
01. Open-type design; currently available shaft-end connection types include splines, flat ends, etc. The port orientation, specifications, and shaft-end connections can also be customized according to user requirements.
02. The pump incorporates a flow control valve to maintain constant output flow; it is also equipped with a safety valve to prevent hydraulic system overload—this is an internally feedback-controlled design.
03. Three-piece construction
