• CAPACITY130 TO 3000 m3/hr.
• ULTIMATE VACUUM0.01 mbar

• roots blowers1620 AC to 2266 AC.
• ranges8000 m3/hr to 64000 m3/hr

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.

• blowers36 AC to 615AC

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.

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.
