AC diaphragm pump VC0201B dual type, 20 l/min - Nitto Kohki 193113302

This series produces pressure and vacuum from one unit, working across a range of -213 mbar to 0.26 bar at flow rates of 6 to 25 l/min. The pumps run on 230 V at 50 Hz and draw only 6 to 27 W depending on the model.

• Dual type versions serve suction and pressure side at the same time, while blower type models cover pure pressure duties
• Low power draw of 6 to 27 W on 230 V, which suits small equipment that runs around the clock
• Maintenance can be scheduled against the stated service life of 5,000 to 10,000 operating hours
• Nearly all models are rated for continuous duty, one version is designed for a 60 minute duty cycle
• Space-saving installation, with mounting dimensions between 66 x 100 mm and 125 x 56 mm at weights of 0.45 to 1.7 kg
• Direct hose connection via nipples of 6 to 10.5 mm outside diameter, with separate inlet and outlet ports

Technical data

Applications

• Air delivery and sample intake in analytical and measuring instruments
• Aeration of small water circuits and tanks
• Picking up and holding light parts in handling equipment
• Pressure and vacuum supply in dosing and laboratory devices
• Air feed in cleaning and inspection fixtures

Operating principle

A coil moves a diaphragm that displaces air through valves between inlet and outlet. Because no piston and cylinder are involved, the assembly stays light, with series weights starting at 0.45 kg.

Standards and compliance

Coil insulation is classified to JETL as class E or B for 230 V and class A for 120 V, depending on the model.
