Kay International Limited Kundli, Haryana

This series covers the roots blowers from 1620 AC to 2266 AC, 2KHC series is the high capacity series. In 2KHC 2 stands for twin lobe roots blower, K for Kay and HC for high capacity.Series covers only air cooled blowers with forced lubrication systems, Capacity for 2KHC series ranges from 8000 m3hr to 64000 m3hr with pressure application from 1000 mmwg (0.1 kgcm2) to 10000 mmwg (1 kgcm2), 5 bearing with shaft roller bearing is well suited for V-belt as well as direct coupled drive, 2KHC series is the series of high capacity roots blowers and is applicable where large quantity of air is required with pressure. (Up to 1 kgcm2).Casings are newly designed one piece style, including extra deep ring section for greater rigidity under vacuum of pressure service. In many of the longer cases inspection ports are provided to give access for internal and clearance check, Impellers and Shaft are made of SG iron and separate forged shaft duly precision machined is shrink fitted accurately machined for close tolerance operation S . G Iron Forged steel material is used for better strength and longer life.Steel shafts are made from alloy steel [BS : 970 series of steel] toughened to resist bending and for imparting high fatigue life. The shrink fit through the impeller eliminates torsional deflection and permits increased pressure ratings and greater efficiencies.

The uniqueness of the DRY-HIGH VACUUM PUMP (Positive Displacement Type) is that it is capable of attaining 28” Hg vacuum & eliminates the need for water or oil sealing. The 3HVP Series pumps do not require Heat Exchanger are suitable for inlet temperatures without use of Pre coolers.5 Bearings with shaft roller bearing suitable for V-Belt & Direct drives, Hardened & Ground Helical Gears located on the drive side for more input torque capability, Piston Ring Seals for lifetime reliability, Heavy – Duty Bearing Holders on thrust end for more axial load capability, Large Oil Sumps for improved bearing lubrication, Hardened & Ground forged Steel Shafts fitted in the Tri-Lobes duly dynamically balanced.

This series covers the blowers from 36 AC to 615AC, KE series was developed during the early days of Kay Engineering, hence called as KE Series Blower, Series covers the air cooled as well as water cooled blowers. Above 7000mmwg water cooled blowers will be supplied, Capacity for KE series Blowers ranges from 60m3hr to 1431m3hr with pressure application from 1000mmwg (0.1kgcm2) to 10000mmwg (1.0kgcm2), Material of construction of the casing and lobes for all blowers in this series is C.I.F.G.-260 conforming to IS: 210, Shaft material from 36AC to 59AC is alloy steel, EN9 (070M55).and above 59AC it is EN24 (817M40) conforming to BS: 970.

High Vacuum upto 0.01 mbar or better, International design compliance to APIISOBSCE certified standards.Advance technology Double sealing system for leak proof design, Oil & Water free dry running operation makes clean operation, Suitable for pumping toxic, corrosive and condensable gas by special material of construction, No metal to metal contact between screws and Casing ensures long pump life, Relatively low power consumption and low maintenance, Considerable reduction in pump down time of vacuum machines, Dry Pumping suitable for gas vapor load, Low energy consumption.
