Design: Horizontal, radial split, volute casing pumps according to ANSI B73-1 specifications with open impeller, end suction, top centre line discharge. Simple external axial adjustment for impeller wear. Back pull out design enables to remove the rotor without disturbing the pipelines. If a spacer coupling is used, the motor does not have to be removed from the base plate. Only four bearing beds cover the entire 32 models. This means that the shafts, sleeves, bearings, and bearing beds are identical in and interchangeable for a large number of pump sizes
