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) but the water tank is also available with prepared water connection in the right side.
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 situ­ation.
*) The C in the pump designation C3K stands for "Ceramic".

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.

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 should always be connected and the hot inlet water should never exceed 80°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.
Power should be connected through a flexible rubber cable holding copper conductors for 3 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 station and outlet points should be placed so that the lines 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 should be fitted in a visual location everywhere or so that they may easily 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 in dimensions according to DIN 2391 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 pres­sure 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.
