Sigma Group has specified Thordon Bearings’ grease-free bearings for its specialized pumping sets for flood defence and irrigation projects across Egypt. Thordon Bearings is supplying 64 of its water-lubricated composite bearings for use in 49 Sigma BQBV vertical diagonal pumps specified for projects along the Nile River and the Sinai Peninsula.
Sigma has already delivered nine 800-BQBV pumps for projects in North Sinai, while twelve 1400-BQBV pumps are scheduled for installation at the El-Hammam agricultural wastewater treatment facility later this month. Twenty eight 1500-BQBV pumps are also being built for the Mostakbal Misr project, with deliveries taking place from June 2023 through to April 2024.
With a much lower friction coefficient than rubber, Thordon’s composite bearing material has been specially developed for use in very abrasive aquatic environments. It is also much easier to install and maintain than alternative bearing solutions.
Sigma is currently working on its second major pump project in Egypt – the El Hamam project. All twelve Sigma 1400-BQBV vertical pumps, each of which is fitted with two Thordon composite bearings, will pump 6 million m2 of agricultural water from the north of the Nile to irrigate a 2100 km2 area 120km to the west, in the Western Desert.
