Rotary vane vacuum pump-Huatai Hehe (Beijing) Trading Co., Ltd

01Product Description

This series of pumps is suitable for pumping air and other general gases. It adopts an oil pump forced oil feeding device, which has the advantage of continuous operation even when the inlet pressure is ≤1.33×10 ⁻ ¹ Pa (Note: The original text lacks the unit of pressure; 1.33×10 ⁻ ¹ Pa is a common pressure parameter for such pumps, and it is recommended to confirm the specific unit in actual use).

It can be used independently, or as a backing pump, holding pump for booster pumps, diffusion pumps, and molecular pumps, as well as a pre-pumping pump for titanium pumps. It is widely applicable to vacuum operations and supporting uses in fields such as vacuum metallurgy, vacuum coating, vacuum drying, freeze-drying, vacuum degassing, vacuum packaging, vacuum adsorption, vacuum forming, food packaging, printing, sputtering, vacuum casting, photovoltaics, aerospace technology, chemical industry, electronics, refrigerator and air-conditioning production lines, and laboratories.

02Product Advantage

Equipped with a specially designed gas ballast valve to prevent water mixing in the pump oil and extend the service life of the pump oil.

◆ High pumping efficiency, high ultimate vacuum, and long service life.

◆ Equipped with an automatic anti-backflow check valve to prevent oil backflow.

◆ Can be equipped with small-caliber adapters, KF interfaces, and flange interfaces.

◆ When pumping gases containing vapor, particles, or corrosive substances, auxiliary equipment such as condensers and dust collectors must be installed at the pump's air inlet.

Product Applications

◆Freeze dryers, rotary evaporators, vacuum dryers, cleaning machines.

◆centrifugal concentrators, glove boxes, tube furnaces, double-row tube suction filtration.

◆suction filtration,coating,sputtering equipment.

◆ Backing pumps for various high-vacuum systems.
