Each of the new, dry-installed KRT submersible motor pumps weighs over nine tons and is driven by a 335 kW, 4160 volt motor. The units' individual flow rate is 35,000 gpm.
Used as main influent pumps, the units deliver raw waste water from the sewer system into the treatment plant. They will replace existing pumps that have suffered damage from being flooded over time during large storms and hurricanes.
In response to the increasing risk of storm damage, a local consortium started in 2006 to redesign the pump station of the "Puerto Nuevo Plant" to ensure its functional availability even when it is flooded. The waste water treatment plant services the City of San Juan and the northern part of the island of Puerto Rico.
Although competition was strong, the deciding factor in the bid evaluation and the subsequent award of the contract was KSB's demonstrable successful experience with medium voltage submersibles in the US marketplace.
