New Micro & Miniature Size Pumps

Namiki diaphragm pumps

The Japanese company Namiki Precision Jewel Co. Ltd announces the launch of micro & miniature diaphragm pumps. The pumps are compact and light, only 20 mm of width, to meet wide range of applications such as analyzers and printing equipment.

Carefully selected materials in construction and unique diaphragm technology provide good chemical resistance, maintenance free and long life operation. Powered by a special design, Namikiís DC coreless motor provides outstanding performance with very low current consumption.

The pumps use Namiki patented non-return valves and are powered by a DC coreless motor only 18 mm diameter.

Two versions are available, 5013 designed for 12 volt operation and 5014 for 24v volt systems.

The maximum flow rate is 180l/min (12v) and 190ml/min (24v). The exhaust pressure range is 0 to +70kPa. The suction pressure range is -30 to 0 kPa for both models.

The pumps can handle fluids at temperatures ranging from +5 to 40 degrees Celsius. The pump can be customised for OEM applications. Standard applications include medical and laboratory analysers ,chemical dosing equipment and environment analysers.

More information can be obtained at the company's website.
