The ROVATTI SK range of horizontal multistage centrifugal pumps are heavy-duty, high-pressure industrial quality pumps designed for demanding water supply, irrigation, and industrial applications. The SK series features a single bearing, end-suction design with an upward-facing delivery flange, settable to 3 different positions by rotating through 90 degrees. Specifications include gland packing seals for simple and economical maintenance and external securing tie bolts for ease of disassembly. Construction material is electro-plated cast iron, except for the SK65-22 models, which feature brass impellers. Cast stainless steel impellers are also available on request.
A wide range of models are available, a combination of the pump size and number of stages being selected to achieve maximum efficiency at a specific duty point. Electric motors are selected according to the required power input at the duty point and mounted together with the pump and coupling on a base frame. All pumps are also suitable for direct or belt drive by diesel engines.
