How can flow be increased from a rotary piston pump?

Increasing flow from a rotary piston pump can be effectively achieved by moving the reaction ring farther off center. In a rotary piston pump, the design includes a reaction ring that influences the relationship between the pump's rotation and the fluid movement within the pump. When the reaction ring is positioned off-center, it enhances the pump's capacity to draw in and expel more fluid with each rotation, thereby increasing the overall flow rate.

Moving the reaction ring slightly alters the effective volume displacement of the pump, allowing more fluid to be moved per cycle. This mechanical adjustment leverages the pump's inherent design to maximize flow without requiring other modifications, making it a straightforward and efficient way to achieve higher flow rates.

Other choices would not effectively increase flow: reducing pump speed would typically decrease the flow amount, increasing oil temperature could change the viscosity but doesn't inherently improve flow volume, and using a larger diameter cylinder might not be feasible unless the pump design allows for it, as it would also require corresponding changes to other components to maintain functionality.
