For sterile product transfer, aseptic versions with steam barriers on all atmospheric interfaces are available. How does a circumferential piston pump work? What is a piston pump and how does a piston pump work? This positive displacement piston pump features a pair of winged rotors or pistons that rotate within the pump casing, moving fluid around the circumference of the channel. As the rotors unmesh, they create a partial vacuum at the suction port, drawing fluid into the pump. The unique design of circumferential piston pumps ensures efficient fluid transfer as the rotors transport the liquid around the channel. When the rotors re-mesh, they generate pressure, displacing the fluid at the discharge port. The direction of flow in a circumferential piston pump is reversible, making it a versatile low NPSHr pump solution for various industries.
