up to 2.5m diameter with the 2" valve (or the
equivalent square/rectangular area).
against the wall of the sump causing agitation and
swirling which lifts deposits from the floor and walls
while at the same time breaking up any crusts which
may have formed on the surface.
How does it function:
Flushing valve piston inside
cylinder (rest position)
Water level in pump sump rises.
Floating ball in housing goes
upwards and valve is opened.
Pump sump is full: by means
of the level control system a
contact is operated and the
mini compressor starts. The
piston moves out, the floating
ball is held in the upper position,
The pre-set timer (approx.10
seconds) on the pump switches
on: flushing begins, the flushing
then continues for the length of
the pre-set flushing time,
e.g. 30 seconds.
Flushing time finished, mini
compressor switches off,
piston retracts, pump runs on.
The floating ball no longer
held in position and is sucked
downwards by the vacuum
produced in the housing. It is
then pressed against the outlet
opening of the valve thereby
closing off the opening.
Normal pumping of the
effluent into the discharge line
then commences.
The Control Unit
The control unit consist of:
Flushing timer relay (1-180 seconds as
standard), contactor with a delay relay, mini
compressor, terminal board,. All parts are
fitted on a mounting plate. The flush time is
pre-set at 30 seconds but is easily altered in
the control panel. Important see setting
instructions on page 6.
Installation
The valve can be installed :
1. Installed with intermediate clamping piece
(accessory) between the pedestal bracket and
the pump flange (pedestal 6 232 0652 or 6
232 0635/0654).
2. Between discharge flange and pedestal
flange (pedestal 6 232 0652
The air hose from the cylinder to the
control unit must be secured in such a way
that it does not kink, restrict the flow of air
or become dislodged from the unit.
The flushing valve is designed to clean sumps
It directs a jet of high velocity liquid
