Large end suction pump range upgraded

Weir Pumps’ ‘Isoglide’ and ‘Swallowglide’ ranges of end suction pumps have gained a reputation for reliable and effi- cient service in traditional dry- well pumping installations worldwide. Now Weir’s experi- ence in the design and applica- tion of large end suction pumps for clean water and various solids handling applications, including sewage, has been

applied to a major upgrading of the range.

The result is a flexible range of high efficiency, modular- design large end suction pumps capable of a wide range of appli- cations from sewage handling through to clean water applica- tions such as water treatment backwash duties. The duty range extends to flowrates up to 6000 ml/hr and head up to 90 m. The development includes a sub- mersible sewage pump option which incorporates the design features of the dry well pump.
