SALIENT FEATURES

Dimensions and specifications are approximate and subject to change.

 The power figures are for vacuum pumps only. For water-ring compressors please request further details.

 The vacuum pump performance shown here is referred to 760 mm Hg barometer (sea level). 50% relative humidity with 30’C seal water temperature at 1.5 kg/cm2 pressure.

 Guaranteed vacuum up to 710 mm Hg at close suction & 760 mm barometric pressure.

 Higher vacuum can be achieved by using chilled water as seal medium or ejectors.

 Suction capacity mentioned is maximum suction capacity with open suction

These are combined Vacuum-cum-Pressure pumps, designed and manufactured for long trouble free operating life. These are basically air-cooled, rotary pumps. Being compact, light weight and easily assembled, they required minimum attention even in continuous operation. Accessories like Vacuum and pressure regulators. Vacuum and pressure gauges, relief valves, inlets filter, exhaust oil baffle etc. are available for different models.

 

APPLICATIONS

• Vacuum lifting

• Paper and Label handling in printing and labeling machine

• Evacuation of containers in food-packing

• Vacuum forming

• Air sampling

• Bottle filling

These are of oil-immersed, rotary vane type pumps. The rotor, with two spring loaded vanes, is mounted eccentric in the stator body. As the rotor, rotates the vanes sweep the crescent shape air space twice in each revolution. There is in-built non-return valve which prevents back flow of air.
Manufactured from graded material, all moving parts are precisely machined, ground and assembled with close tolerances. This results in increased efficiency and long trouble free operating life.

Water Ring Vacuum Pumps

ACCESSORIES

Air Ballast :-This is a vent pipe introducing air before actual compression which eliminates
condensation of the sucked vapour, there by avoiding contamination of oil.

Air Admittance Valve: It is electromagnetic solenoid type which admits air into the system as soon as the power supply fails. This prevents back-flow of oil to the system.

Non-Return Valve: It is rubber diaphragm type, spring loaded valve, which prevents back-flow of oil to the system as soon as pump stops. These can not be used to hold the vacuum in the
system for longer period.

• Moisture Trap, Inlet Dust Filter, Vacuum Gauge with Regulator, Trolley for small Pumps.

• USE Oil: ENCLO – 46 (HP) SAE – 30 or Equivalent Vacuum Oil.

• Model HL – 300 – II and above, are provided with water cooling jacket.

• Vacuum Measured Mcleod gauge at suction port of the pump.
