As a technology leader, KNF offers OEM gas and liquid pumps that enable design engineers to create high-quality systems and devices across multiple industries. We understand and anticipate the needs of each customer and every environment in which our pumps will perform. Additionally, our modular system allows us to custom-design pumps to meet your specific application requirements using a variety of specialized parts and materials.

Stepper motor-driven

Our FEM dosing pumps are based on a very simple design. The stepper motor causes a cam to rotate and this, in turn, moves the diaphragm up and down. This vertical movement causes pressure changes in the pump chamber which, combined with the operation of the inlet and outlet valves, produce the pump action. Various hydraulic connections are available.
