Principle of Screw Coolant Pumps

Screw coolant pumps operate using one or more rotating screws that create a continuous, smooth flow of coolant. As the screws turn, they form sealed cavities that move the coolant from the inlet to the outlet with minimal turbulence. This positive displacement mechanism ensures consistent pressure, low pulsation, and efficient fluid transfer, making them ideal for cooling and lubrication applications in machining and industrial processes.
