Watson-Marlow Pumps Group offers the 400RX for catheter washing and cooling applications requiring pressures up to 90 psi, or flow rates up to 100 ml/min. The pump can achieve the high pressures due to its precision machined components, and spring loaded track to maintain occlusion of the tubing under high pressure. All fluid being pumped is completely contained within the tubing, so cleaning the pump is as simple as replacing a disposable tube-set.

The pump has a unique cover/ loading lever that lifts the track when opened facilitate loading of the disposable tubing. The tube loading procedure is intuitive and fool-proof, and there are no extensive tools, adjustments, or training required. The cover comes with an integrated switch that can be wired to turn the pump off when the cover is opened. When closed, the clear cover gives a full view of the pump operation, and verification that the tube is loaded correctly.

The pump accepts tube sizes from 1/6” to 3/16” ID, and has 4 stainless steel rollers for low pulsation of the flow stream. The rollers use low-friction ball bearings for optimum tube life at high pressures.

The pump is available to medical device customers as a complete plug-and-play cased pump, or as a panel mount OEM unit. Drive options for the 400/RX includes brushless, or stepper motors both with built-in drives.

Every Watson-Marlow peristaltic pump is an inherent metering pump with repeatability at 99.5%. Many models include integral digital drives with PROFIBUS or SCADA control in NEMA 4X washdown enclosures. These self-priming pumps accommodate flow rates from 0.1 microliter to 350 gpm, and are extremely durable, withstanding pressures up to 232 psi. There are no internal universal joints, valves, dead corners, or glands to impede flow and these pumps are reversible for back flushing lines. They can also run dry indefinitely without damage and provide up to a 30’ suction lift.
