Product Description

Layout of system
The DELTABOOSTER is a flexible pump station capable of supplying several simultaneous
users with pressurized cold / hot water through a pipeline. The DELTABOOSTER has been
pre-adjusted for a certain line pressure which is also the maximum working pressure.
For the DELTABOOSTER a system of nine different spray lances has been developed. From
a diagram the user can choose the lance giving the exact pressure and water volume required
for his cleaning job.
As standard the DELTABOOSTER system is available with capacities from 2 - 6 users and
pre-adjusted at a line pressure of 160 bar (other pressures are available according to wishes
of the customer).
A plant with a capacity for 3 users can be upgraded to 4, 5, or 6 users at any time, and more
DELTABOOSTER plants can be connected up on the same pipeline.
With the DELTABOOSTER users no longer have to bother about the pros and cons of high
or low pressure. From now on all choices are united in one system, and the solution with the
optimal effect on the job to be done may always be found.
In more technical terms the plant operates in the following way:
Water from a COLD and a HOT connecting valve is mixed in a water tank of the type A airgap.
From here water of the required temperature is drawn into the high pressure pumps of the
DELTABOOSTER which pressurize the water and supply it to a pipeline.
When one or more outlet points are being used, the number of pumps required to maintain the
pressure will automatically start up.
When the cleaning stops successively, one of the excess pumps will cease operation each 15
sec. If all cleaning is stopped then controls will ensure that the requisite pressure for re-starting
is maintained. If a leakage is caused to the pipe system then the pump station will be totally
switched off after some 2 minutes. In the case of an internal hose leakage in the system, faulty
water supplies, excess temperature of inlet water, excess motor temperature or excess power
consumption the system will be switched off.
When starting and stopping the individual pumps, controls will ensure an even distribution of
operation time on the pumps by switching between all the pumps in the system.
