400/RXMD series panel mount pumps


400/RXMD pressure controlled low-flow pump

Purpose-designed for surgical cooling applications such as RF and microwave ablation.

400/RXMD series pumps is the definitive OEM peristaltic pump used in surgical ablation systems. It is designed to meet the needs of catheter, cannula or needle cooling applications. Minimizing the risk of human error, 400/RXMD safeguards your process by design. The ability to factory-set the pump means that the pressure/flow profile can be fine-tuned to the requirements of each application. We therefore test every pump to each customer's specific test protocol.

Motor options include a stepper motor, brushless DC motor and DriveSure.

Features and benefits
