1. 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.

1.1 Model survey and main functions
The DELTABOOSTER comprises 4 different modules:
1. A switchboard
2. A water tank
3. KEW Technology C3K pumps
4. Cabinet / frame
The DELTABOOSTER is made of stainless materials through and through.
DELTABOOSTER switchboard
The switchboard comprises:
- main (emergency) switch, to which the supply cable is connected
- control switch 24V AC
- push-button switch for starting up
- maximum current breaker (short circuit and overload) for each pump
- contactors for connection of 3 or 6 pumps.
The switchboard also incorporates an electronic control that monitors the operation of the
system; i.e. a) selection at any time of required pump capacity; b) even distribution of load on
individual pumps; c) mixing of desired temperature of water drawn from a cold water and a
hot water supply and d) the indication of status/fault on a control panel.
It also incorporates hour meters to show hours of operation of each individual pump.
The switchboard has been prepared for
connection of 6-pumps: (4, 5, and 6 pump plants)
or for connection of 3-pumps: (2 and 3 pump plants)
The switchboard which on delivery controls 3 pumps may later be expanded to control
6-pumps.
The DELTABOOSTER is available for the following voltages:
3 x 230V 50 and 60 Hz + earth (PE)
3 x 346-400V, 50 and 60 Hz + earth (PE)
3 x 415-440V, 50 and 60 Hz + earth (PE)

Water tank
The water tank of the DELTABOOSTER has been constructed in accordance with BS 6281 part
1 (type A air gap). As standard the water tank is mounted for water connection in the left side
(seen from in front). The water connection can be moved to the right side by a Nilfisk-ALTO
service technician. (Water tank can be turned 180 degrees in the frame).
The water tank of the DELTABOOSTER incorporates the following:
- two solenoid valves for water inlet, cold and hot water respectively
- various control valves
- temperature sensor and level switches in the float tank
- overflow
- connection of up to 6 pumps
- filters in in-lets
C3K pumps
The C3K pumps are designed for the very demanding environments in which they are used.Their
durability has been achieved by the use of ceramic pistons *)and valves of stainless steel.
Each of the pumps are connected by individual non-return valves to a central manifold. Thus it
is ensured that a defective pump will not cause a malfunction or an unintentional by-pass situ-
ation.
*)The Cin the pump designation C3K stands for "Ceramic".

Original Instructions
1.2 Selection of system
The great degree of flexibility, an important characteristic of the DELTABOOSTER, means that
each individual customer may select the system which suits his cleaning needs.
The following solutions are offered:
NUMBER OF PUMPS
Choose from 2 to 6 pumps depending on the capacity required at the same time. In other words,
the number of pumps should be decided on the basis of the number of places that are to use
the system at one and the same time.
LINE PRESSURE
The line pressure is the maximum working pressure for the individual user and is of importance
to the dimensioning of the pipeline, of course.
As a standard the system is adjusted to a line pressure of either 120 bar or 160 bar, but it may
be adjusted to a line pressure within the area 90 to 160 bar. This adjustment should only be
done by a specialized Nilfisk-ALTO customer engineer.
SELECTION OF SPRAY LANCE
For each of the line pressures (120 and 160 bar) there are nine different spray lances developed
especially for the DELTABOOSTER. Each of the nine spray lances represents a combination
of pressure and water volume. Users may therefore always select the job-right combination of
pressure and water volume.

Original Instructions
1.5 Installation requirements for water connection
The water tank is fitted with two water inlets, one for cold water (BLUE marking) and one for hot
water (RED marking).This allows the operator to control the temperature of the water being used.
If no temperature control is desired both water inlets may be attached to the cold pipeline.
At least 1 cold water inlet (8-12°C) should always be connected and the hot inlet water should
never exceed 85°C.
Each pipeline should be capable of supplying the system with at least the water volume that
answers to the capacity of the system ( no. of pumps - l/min, cf. 1.3.3) and at min. 2 bar. The
water pressure must not exceed 10 bar. If water is being drawn from the lines at other points,
the line capacity should be equally bigger.
In order to achieve optimal temperature control the shut-off valves on both the hot and the cold
pipeline should be adjusted so that the water volume of each line comes as close to the required
water volume as possible.
Water should be connected at the inlet sockets with two 1" flexible hose connections (included
in the MK-Mountig Kit).The two water inlet hoses are 1 m long and fitted with a 1" external taper
pipe thread. Shut-off valves should be fitted right next to the connections on the supply lines, but
no extra non-return valve is required as the system is fitted with an airgap type water tank.
If the water holds running sand or other impurities external filters should be fitted in addition to
the internal filters.
The high-pressure connection to the pipe system should be by means of the 3/4" high-pressure
hose supplied with the system. The hose is fitted with an Ø22 plain branch for connecting to
cutting ring hose connection.

1.6 Installation requirements for mains power connection
The power system of the DELTABOOSTER is designed in conformity with the common Euro-
pean standard:
EN 60204-1 (October 1992): Electrical equipment of machines, Part 1: General requirements.
Powershouldbe connected througha flexible rubbercableholding copper conductorsfor3 phases
and earth (PE).The minimum dimensions of the cable are determined by the power consumption
of the current system (cf. data sheet), but common to all systems is the following:
Max pre-fuse: 125 A
Max core section of cable: 35 mm
In consideration of a future extension of the plant we recommend you to use a cable with a min.
core section of cable of 25 mm.
Earth wire protection is required and the connection of the DELTABOOSTER to the mains power
supply MUST be carried out by an authorized electrician in conformity with local regulations.
To ensure maximum protection of persons, the installation should be protected by a Residual
Current Device (RCD).

1.7 Pipe system
1.7.1 Location of pipelines/general instructions
- The pump stationand outlet points should be placed so that thelines become as short as
possible.
- The line should be arranged with as few bends as possible.
- Sometimes it may pay to split the line close to the pump station so the lengths conducting
large volumes of water become as short as possible. A centre location of the pump station
in relation to the outlet points would also lead to smaller pipe dimensions.
- Pipe lines should be placed on walls of tile or concrete, otherwise great care should be taken
(reinforcement plates etc.)
- Pipe lines should be placed so that damage is prevented (collision, frost, extreme attacks of
corrosion, etc.)
- Pipe lines shouldbe fitted in a visual location everywhere or sothat theymayeasily be
inspected. Lines should not be incorporated in walls or floors. When leading through walls
be careful not to enclosed. (Special lead-in bushes are available)
- The outlet points should be placed as close to the operation point as possible and so that a
hose length preferably of 20 m is used.
1.7.2 Types of pipes - standards
Seamless pipes of precision steel are used for the pipe system according to DIN 2391/C of St.
35.4 material quality, normalized, bright annealed and electro galvanized or welded steel pipes,
stainless, calibrated and glowed according to DIN 2463 - 1.401 d3-- (DIN 17457 cl. 1).
Alternatively, seamless pipes of precision steel indimensions according to DIN2391 and stainless
material quality e.g. Werkstoff no. 1.4301, 1.4436 or 1.4571. Comparable qualities to Swedish
standards are SIS 2333 or SIS 2343.
Pipe dimensions:
The following sizes are used with electro galvanized precision steel pipes:
- ∅15x2
- ∅22x2.5
- ∅30x4
The following sizes are used with stainless precision steel pipes:
- ∅15x1.5
- ∅22x2
- ∅30x3
In connection with branches close to the pump station it should be possible to avoid the ∅30
dimension for most 44C3 systems. For 160 bar systems fittings with a permissible working pres-
sure of min. ND 160 bar are to be used.
Please note that the pipe dimension ∅30 according to DIN 2353 is used together with a stronger
type of fitting (S-series) and pipe systems with this dimension therefore become more expensive
than e.g. an ∅22 line - particularly in multi-pump systems.
