Founded more than 65 years ago, Selwood is one of the largest privately run companies in Great Britain in the field of construction equipment rental.
It is both the leading pump supplier in Great Britain and the leading supplier of construction equipment and accessories on the south coast. Selwood has been developing and producing mobile pumps for more than 50 years and has thus become the market leader in Great Britain in this area. Selwood’s pump success is based on constant growth, innovation and entrepreneurial spirit. Since its beginnings in 1955, the company has consistently focused on expansion into new markets at home and abroad. At present 70% of pump production is produced for a worldwide dealer network. Selwood’s original pump design and the internationally known names such as “Simplite”, “Spate” and “Seltorque” quickly established themselves as the market standard in the construction industry. Continuous further development of these designs is an important part of these series of vacuum-assisted pumps. Today Selwood covers a wide range of applications in many branches of industry, construction, marine, environmental and flood protection, mining and wastewater treatment. This broad spectrum requires a wide choice of materials in order to pump media with solids, suspensions such as bentonite, sludges and oil-containing media.
