Softly softly
May 1st 2008 Dold's new IL 9017/300 - 1.5kW
and BI 9028.38/900 - 7.5kW, singlephase
soft start, soft stop units
have been designed to reduce
borehole pump starting current
and minimise the effects of starting
torque and water hammer. Fitment
will reduce repairs on broken pipe
work and blocked filters, often
caused by debris pick up on the
pump filters, when excessive pipe
work movement takes place when
starting and stopping the pump.
These units are suitable for use
with 230Vac motors and have
adjustable ramp times and start
torque settings. Both units have
built in bypass contactors for 100%
running efficiency and low EMC
emissions. They reduce motor
starting current by up to 30%. More articles from Dold Industries Ltd: |
