Two Stage Liquid Ring Vacuum Pump

Introduction

The 2BEC TWO-STAGE LIQUID RING VACUUM PUMP is a non-pulsating vacuum pump designed to remove gases through the use of rotating impeller blades that enter and leave a ring of liquid. The impeller forces this sealing liquid to the periphery of the pump casing where it forms a moving ring of liquid around a center void

Like single-stage vacuum pumps, two-stage vacuum pumps come with impellers. But the difference is, two-stage pumps have two suction impellers that operate side by side. Those who will be operating must choose between more pressure and volume. Well, you can find these options on the pump panel.

Dual-stage vacuum pumps or two-stage vacuum pumps are high in a mated vacuum and low in a vacuum. Mainly, the low vacuum stage plays a crucial role in improving the performance of your vacuum pump. The reason is, the low vacuum stage in a two-stage vacuum pump compresses the gas into atmospheric pressure.

Contrastingly, a two-stage vacuum pump’s high vacuum stage amalgamates the process and sends it to the second stage.

The impeller shaft is mounted above the centerline of the casing while the blades, although rotating concentrically, are located eccentrically with respect to the casing and the ring of liquid. The TWO STAGE LIQUID RING VACUUM PUMP’s axial suction and discharge ports are exposed to the void but separated by the impeller blades and the ring of liquid. As the process gas or vapor is drawn into the pump through the suction port, it is trapped between the impeller blades and the liquid ring. The rotating blades enter deeper into the liquid ring progressively reducing the entrapment space, compressing and then exhausting the gas through the discharge port. The liquid ring acts like a liquid piston, meaning the entire pumping operation is accomplished without vanes, valves, pistons or any metal-to-metal contact.

Features

●Impellers positively locked to shaft

●Reliable mechanical seals for high-integrity sealing and low shaft friction

●Center-anchored tie rods allow access to either end of the pump without total disassembly

●Precision casting and CNC machining eliminates the need for body gasketing (process dependent)

●Replaceable end plates

●Clearance adjustments via shims

By accumulating all information about the two-stage vacuum pump, we got to know how efficient this pump is. Other than that, a two-stage pump will always give a high level of vacuum performance. Thus, getting numerous benefits from a two-stage pump is very obvious for us.

• Suitable for numerous process applications

• Performance is more brilliant than a single-stage vacuum pump.

• Requires less water and saves energy within minimum power

• Convenient with lots of accessories. Such as corrosion-resistant coatings and mechanical seals.

As mentioned before, a two-stage vacuum pump comes with two rotors and one vane. Accordingly, the first stage of it simulates vacuum, whereas the second stage engages in cleaning the entire system. So whenever you want to banish dirt from your places, you will need a reliable vacuum performance.

For now, a vacuum pump with pressure can come out really handy. In such cases, a two-stage vacuum pump will be a fine option for you.
