New India Electricals Ltd a Gear Pump suppliers in Bangalore. Gear pumps are positive displacement Pumps, a popular pumping principle. These are often used for pumping lubricating Liquids, Oils, and other Viscous Liquids. Gear pumps come in either single or double (two sets of gears) pump configurations with spur (shown), helical, and herringbone gears. It is well known that, Helical and herringbone gears typically offer a smoother flow than spur gears, though all gear types are relatively smooth. For this reason, our large-capacity gear pumps use helical or herringbone gears.
