RS PRO Diaphragm Electric Operated Positive Displacement Pump, 0.4L/min, -500/800 mBar, 2 → 4.5V

Use these positive displacement pumps from the RS PRO range in gas detection and monitoring systems. Part of the D200 series, the electric pumps are made from aluminium.

Durable stainless steel has been used for the tubing connectors and the pump's push-fit connectors are designed for 2.4 mm bore flexible tubing. Gases and liquids can flow through the device at a variable rate. With low power-consumption, the pump also has protection against chemicals such as petrol, bleach and kerosene. Realign the pump head to one of four positions to easily connect to the inlet or outlet tube.

Suitable for battery and solar-powered systems, cooling systems and environments where precise flow is needed, these positive displacement pumps are rated IP41 for standards relating to protection against intrusion from tools, dirt and moisture.
