Pump Pomvak, Turkey analogue BBH

Liquid ring vacuum pumps are suitable, depending on material flow part, for pumping (vacuum) air, inert or aggressive gases, insoluble in water, with the purpose of creating or maintaining a vacuum.

Pumps of monoblock type (series PVM and PVN)

Pumps POM - VAK series PVM and PVN compact, since the pump set on the motor flange and the impeller is mounted directly on the motor shaft. This design makes them more compact and allows you to use requiring small overall dimensions of the pump.
The performance value in the table are valid at a temperature of environment 20 ° C in saturated air at sea level at atmospheric pressure of 760 mm of mercury. article Temperature service water 15.

Single-stage and two-stage pumps (series PVK and PVT)

Unlike monobloc pumps series, pump series PVK and PVT pump and motor are mounted on a common frame. Torque the pump shaft is transmitted through elastic coupling. This design makes the pump much longer and heavier, but much easy maintenance.

Series PVТ is a series single-stage vacuum liquid ring pumps are superior performance. To improve The efficiency of the pumps suction and exhaust carried out at the same time through both end caps, two working chambers which are connected the common pipeline, which allows to increase the performance to minimize vibration, noise and increase durability.

PVK series is a series of two-stage liquid ring vacuum pumps.
The outlet of the first chamber connected to the inlet of the second camera. The air passes alternately passes through both cameras. The depth of the vacuum is thus increased, but only slightly. The main advantage of two-stage pumps is additional cleaning of air evacuated and the ability to develop high blood pressure.
These pumps have built in anti-cavitation valve between steps. They are reliable, easy to maintain, they can be used to pump almost any gaseous medium or steam.
As a working fluid in vacuum pumps POM-VAK often is water. That is why they are called liquid ring. In the process of operation, the water needs to be changed. It is forbidden to use water containing lime, because this reduces the service life of the pump. If necessary, you can use any working fluid, properties close to the water. Sometimes together with the gas or vapor in the pump can get dirt and debris. Centrifugal force does not give these particles out of the pump. In order to avoid wear on the pump inlet you should install the filter. In some applications possible from entering the suction line of acids, alkalis or vapors.They can cause chemical corrosion of the flow part. Therefore, you should select material of flowing part, according to the working conditions.

In the basic version, the pump housing is made of cast iron, working wheel of bronze, shaft of stainless steel. Pump seal – the gland or end.
