Valve&pump integrated is a product of combining precision piston pump and solenoid valve that is independently developed by Keyto, its mainly function is to achieve accurate quantitative aspiration and dispense of liquid. The piston pump has high accuracy and CV value, and its service life can reach more than 5 million times. It is a high performance, low cost, maintenance-free precision piston pump. Valve&pump integrated has been widely used in medical devices and laboratory analytical instruments. Highly Customized: Valve Integrated Syringe Pumps can be customized with different applications, like different specification of flow control maps, different arrangement methods and mounting ports according to customers' requirement.
