Australian Pump has introduced a new cost-effective single phase submersible
pump from Tsurumi Pump, designed for septic tank applications.
Designed specifically for effluent and sewage applications, Tsurumi’s
new UT series cast iron pump is fitted with a unique vortex style impeller that
passes compressible solids of up to 35mm in diameter. Displaying excellent flow
versus head characteristics, the new pump delivers a maximum flow of 440 lpm and
a maximum lift or vertical head of 12.5 metres. Tsurumi developed the product
range in response to requirements in the Japanese market for super tough pumps
for sewage applications.
Aussie Pumps’ Craig Bridgement explains that the UT series submersible
pumps are loaded with features to give homeowners and operators the best
possible longevity and low maintenance costs. Aussie Pumps has been able to
match the quality and features of the pump with a low purchase cost as they
could reduce prices by as much as 35% based on expanded volumes.
Key features of the new UT series submersible sewage pumps include single
phase, capacitor start, electric motors in a 0.4kW to 0.75kW range; heavy duty
10-metre submersible cable; dry type squirrel cage induction style motor housed
in a watertight casing, conforming to class E insulation; ability to operate in
ambient temperatures up to 40¡C; inbuilt thermal motor protection device protecting
the motor during over current or dry run conditions; vortex impeller highly
resistant to abrasion; and unique vortex design allowing solids in suspension
to easily pass through the pump.
The inbuilt thermal motor protection device in the UT series pump reacts
to the heat generated by an over current or dry run conditions by cutting off
the motor automatically and resetting itself. The motor automatically restarts
after cooling down to a safe operating temperature.
Several features in the Tsurumi UT series help enhance the life
expectancy of the pump and reduce maintenance costs. These include a unique
anti-wicking cable gland that prevents water from wicking down inside the cable,
protecting the motor even if the cable is damaged or the end accidentally
immersed. A double silicon carbide mechanical seal in all Tsurumi pumps has both
seal surfaces submerged in an oil chamber, well away from the pumped liquid. A
patented oil lifter ensures the mechanical seal faces are always lubricated and
cooled, even if the pump is installed horizontally.
All Tsurumi pumps are backed by a three-year warranty against faulty
material or workmanship. The Tsurumi UT series is available as standard
effluent pumps as well as in an automatic stop/start version featuring a simple
float control system that prevents dry running, reduces power consumption and
extends operating life.
