A Piston Pump Rotating Barrel serves to convert mechanical power into hydraulic energy, enabling the transmission of pressurized fluid in the hydraulic lines. It consists of a barrel, plate, kit spacer, pin, pistons, and springs that are connected to function properly within the piston pump assembly. It operates by employing a rotating barrel with pistons that reciprocate to draw in and pressurize hydraulic fluid, creating a continuous flow of pressurized fluid to drive the hydraulic unit. Attributes:• Withstands the high pressures and stresses generated during the operation• Provided with 14 screws with thread size of M6 to provide a secure connection with the piston pump parts• Provided with 7 pistons to generate high-pressure hydraulic power with improved smoothness and reduced pulsation Applications:A Piston Pump Rotating Barrel is used to generate fluid flow by utilizing reciprocating pistons within a rotating barrel, providing the necessary hydraulic power for the reliable operation of a hydraulic machine.
