Liquid Ring Vacuum Pump
These combine the two-fold features of suction and pressure and hence the same unit can be employed for either function. When used as vacuum pump, they can create vacuum up to 720 mm (approx 28" Hg) provided the temperature of the sealant liquid (generally water) is below 30 °C & barometric pressure at site is 30 Inches of Hg.
Generally, the main casing & almost all the components are graded Cast Iron except the main shaft, which is of Stainless Steel. It is also offered in various combinations of resistant materials like SS304 or SS316 for aggressive/specific applications. Details are supplied on demand.
The pumps components are positioned in such a manner as to admit gas when the rotor chamber is emptying the liquid, and then to allow the gas to discharge once compression is completed. Sealing areas between the inlet and discharge port are provided, to close the rotor areas, and to separate the inlet and discharge flows
Salient Features
- Silent and considerably vibration free running
- These types of units are used mainly as vacuum pump but modification for use as compressor possible.
- Simple and trouble free operation.
- Moist Air, aggressive gases and vapors can be handled.
- No metal to metal contact inside machine.
- No lubrication except for bearings.
- Oil Free Exhaust
- No contamination of handled media.
- Compression takes place with small temperature rise.
- Compact unit due to direct drive, higher models can be provided as V-belt driven.
- Simple construction & easy maintenance.
- Mechanical shaft seals on either end of shaft or gland packing (if requested).
