Mississauga, ON – After a rigorous bid selection process, KSB Pumps Inc. has been chosen by the City of Montreal to provide a new water transport pump for the Charles-J.-Des Baillets water treatment plant. This unit will join five other large KSB pumps that have been in continuous service at this plant since it was commissioned in 1978.

The Charles-J.-Des Baillets plant draws water from the St Lawrence River, purifies the water by a combination of ozonisation, filtration, ultraviolet (UV) water treatment and chlorination, and then delivers the water to a system of reservoirs that feeds the city’s distribution system. The plant supplies over one million cubic metres of water every day.

The new 38-tonne KSB pump will operate in parallel with the existing large-capacity pumps installed at the plant. Specially constructed for this project, the pump is an updated replica of the original pumps supplied by KSB. The footprint and layout of the new pump resembles its older counterparts, but up-to-date seals and optimized hydraulic elements will enhance its reliability and improve operating efficiency.

Duplicating the older pump configuration has simplified the installation of the new unit at the Charles-J.-Des Baillets pumphouse. In this area of the plant, the pumps are installed on the lower level of the structure with the motors mounted on a higher floor, where they are protected from flooding.

A 5-metre-long drive shaft connects the new pump to its 5,500-hp motor. Because the new pump has the same layout as its older counterparts, it will be installed alongside them in exactly the same arrangement.

KSB is responsible for supplying the pump, the motor and the drive shaft, along with the supervision of the installation and commissioning of the equipment on-site. Installation is scheduled to be completed in the first quarter of 2014.
