- This pump is on the basis of the circulating water multipurpose vacuum pump, according to the feature of lab area is lesser, improve transparency anti-corrosion tank, anticorrosive shell and stainless steel shell a variety of models, modified reduced volume, has small volume, light weight, appearance and other characteristics, double table, double suction, and is equipped with ice hole. -This machine adopts double tap, can be used alone or in parallel with two vacuum gauge. -Host anti-corrosion material movement models, enclosure for the special engineering plastics. -Equipped with a special fluid muffler, reduce the water gas and liquid friction noise, make the higher vacuum degree more steadily. Corrosion resistance, no pollution, low noise, convenient movement, can also according to user needs to add vacuum valve, easy to operate. -Exhaust tube is equipped with check valve on the road, can prevent the vacuum unplanned downtime, when working in the circulating water flow to the vacuum equipment.
