EWPP prefers Swaby pumps to replace the existing 6" double disc (Model 6DDSX107) pumps due to its capacity for pumping high-viscosity fluids and slurries over long distances or under difficult conditions. It is ideal for handling large particles in drinking water treatment before centrifugation due to its non-clogging design, high efficiency, durability, and ability to reduce centrifuge load while maintaining water quality. Full replacement is necessary to improve system efficiency, minimize downtime, and reduce maintenance costs. 2.2 Quantity 2.2.1 (2) pump/motor packages 2.2.2 (1) Spare parts and special tools package 2.3 LABOR 2.3.1 The vendor shall supply and install the pumps and all components.
