Our Heritage

Crane Building Services & Utilities forms part of the Process Flow Technologies group within Crane Co., which was founded in 1855, and now is a New York Stock Exchange quoted company with a market capitalisation in excess of $2bn, providing a range of innovative pipe fittings and couplings across multiple industries.

The most recent acquisition was Delta Fluid Products in 2008. Each of these companies has a long and distinguished history:

  • Crane Limited founded in Ipswich 1919
  • Viking Johnson founded in Hitchin in the 1930’s
  • WASK founded in Keighley in 1888
  • Delta Fluid Products founded in St Helens in 1900

The name Crane speaks of who we are, what we stand for and how our customers perceive us: a company with history and tradition, but also a company that is innovative, quality minded and one which acts with integrity, still holding to the resolution of its founder.

Richard Teller CraneCrane Co. was founded on 4th July 1855 by Richard Teller Crane who made the following resolution:


“I am resolved to conduct my business in the strictest honesty and fairness; to avoid all deception and trickery; to deal fairly with both customers and competitors; to be liberal and just towards employees; and to put my whole mind upon the business..”


The essence of this resolution is the business policy of Crane Co. today.
