DC diaphragm liquid pump DPE-400-7G 24V - Nitto Kohki 195110007

Moving small volumes of liquid at a steady, repeatable rate is what this range is built for. The pumps run on 24 V DC, prime themselves and deliver against an outlet pressure of up to 3 bar.

• Self-priming at 200 to 400 mbar, so the pump does not have to be flooded before start-up.
• Outlet pressure up to 3 bar, enough for longer lines and narrow cross sections.
• Flow rates from 100 to 800 ml/min cover small-scale dosing and circulation duties.
• Current draw of 600 mA or less at 24 V, an existing control supply is sufficient.
• Rated for continuous operation across a working pressure range of 0 to 1000 mbar.
• A weight of 67 to 350 g and straight nipples of 4.7 or 5.4 mm O.D. fit tight installation spaces.

Applications

• Dosing reagents and process media in analytical instruments
• Circulating coolant and process liquids in small equipment
• Sample feed in laboratory and test rigs
• Topping up and transferring small liquid volumes on machines
• Liquid handling inside equipment with a 24 V control system

Operating principle

A DC brush motor drives the diaphragm through an eccentric. Inlet and outlet valves set the flow direction, and the diaphragm keeps the liquid away from the drive.

Standards and compliance

Winding insulation is rated class E or F, depending on the model.
