In 1958, Sidney Pask, founder of Grantham Engineering Ltd., saw there was a market need for high-quality industrial vibrators. To meet it, he founded Invicta Vibrators as a division of Grantham. Since then, Invicta has been dedicated to the design and manufacture of electrical, pneumatic, and hydraulic vibrator motors for the material handling and process industries. The company is located in Grantham, England.
