Ремонт водокольцевых-жидкостнокольцевых вакуумных насосов ВВН

In Russia and the CIS was carried out and is made not so much of liquid ring vacuum pumps VVN, zhvn, not to list them all in detail.

Let's start with decoding of the legend in the abbreviation of liquid ring vacuum pumps:

In – liquid ring;

W – liquid ring;

In – vacuum;

N – pump;

The numbers after the letters before the dash indicate the performance of the pump that determines the absolute suction pressure corresponding to nominal pump performance:

1 for suction at a pressure of 0.04 MPa (300 mm. Hg.St.) and 2 – for suction at a pressure of 0.02 MPa gauge (150 mm of mercury.St.);

The numbers after the dash – capacity (m3/min);

The letters after the numbers – the material flow of the pump:

N – stainless steel;

X Hastelloy;

T – Titan;

M – modernization;

On many models there are drawings on the major wear parts, therefore, is that the repair is still cheaper than a new pump, even taking into account transportation costs.

Start ascending.
