Tsurumi PU sump pump series
The Tsurumi PU series automatic submersible sump pump system is designed to be simple to set, without the complication and expense of a control box. This means no additional wiring or power is required, other than the standard pump power cable.
The pumps are suitable for both continuous and intermittent sump applications. They are controlled by float switches which are simply adjusted to the required activation height. This means any plumber can control when the pumps start and stop and whether they work together or alternate.
The system uses two automatic pumps, one of which has a third, additional, float switch. The pumps automatically switch on when the water level rises and switch off when no longer required. If the water continues to rise both pumps will work together until the level drops to the pre-set level.
The pumps in the PU series produce flows of up to 800 L/min, with vertical heads of 16 m. The series includes both three-phase and single-phase options with two pole motors (up to 1.5 kW) and are available with 1.5, 2 and 3" discharge bores.
The PU series is made from moulded resin and stainless steel and is, therefore, not only lightweight but also corrosion resistant. The pump’s vortex impeller is made of fibreglass reinforced resin. This type of impeller passes small solids, in suspension, through the pump without damage or clogging.
A double mechanical seal, with two silicon carbide seal faces, operates within an oil chamber to provide maximum seal life. Tsurumi’s Oil Lifter ensures the mechanical seal is continually lubricated, even if the lubricant level falls.
The motors feature a self-resetting thermal protection device that reacts to the heat generated by an overcurrent or dry run conditions. That means that when the motor cools down to a safe operating temperature, the motor automatically restarts.
The series is designed for tough applications in the construction and plumbing industries. The pumps are particularly suited to pumping waste water, sewage and even rainwater that may contain solids.
