ZK series Co mbination Vacuum Pumping Sets/ Oil Filling Machines/water pumping machine/circulating water vacuum pump

Products profile:

       The working vacuum range is 7~133 Pa; the limiting vacuum can be up to 7 Pa. The vacuum unit is quick start and big pumping speed that can be used for vacuum smelting, jointing, pharmacy, electric vacuum device, especially for the vacuum evacuating of transformers.

        ZK unit adopts roots vacuum pump as the main pump, rotary-vane vacuum pump as the fore pump. Between them connecting an electric-magnetic pressure differential valve which would be turned on when the fore pump is working. The inlet of ZK unite equips a micro thermocouple which can meter and control the vacuum of pumped container. All the valves are imported from German with good ability of airproof.

        Circulating vacuum pump oil filter and circulating water cooling device are set up to ensure a reliable operation, keeping normal temperature of circulating water, without vacuum oil aging.

Characteristics

1. Simple structure, easy operation.

2. Fore pump is imported from German; lobe-type pump could be customized as different requirements, no matter homemade or imported device, make sure highly pumping speed and maximum vacuum degree.

3. Equipped filter in pipelines, prevents vacuum pumps from damages by dirt.
