Product Overview:

Engineered for high-rise condominium units experiencing low water pressure—whether from rooftop tanks or underpowered supply systems—the Penthouse/Condo Series offers a compact, efficient solution. This dual-service system features two identical pumps: one designated for hot water and one for cold. To streamline installation, either line can be connected to either pump, allowing for flexible piping configurations.

The Penthouse/Condo SERIES booster pump system is specifically designed for individual high-rise condominium units with low water pressure (whether supplied by roof top tanks or inadequate pumps). Frame stands on floor, and/or affixed to wall. Sound dampening material below and behind frame may be supplied by contractor. Pumps are identical, one pump for Hot Service, the other Cold Service. To simplify piping, hot/cold can run to either pump.

The frame is designed to sit on the floor and may also be secured to the wall for added stability. For quieter operation, sound-dampening material can be installed behind and beneath the frame, typically provided by the contractor.
