Features
DW series incorporate Gaede-type rotaryvane pumps. This series pumps are direct-coupled oil-sealed rotary pumps using two-stage rotor compression.
The rotational speed for this type is higher than for belt-driven models, because motor rotation is transmitted directly to the pump.
DW series supply 7 types of 50 to 1300(60 to 1500)L/min from which customer can select models to meet specification.(60Hz)
