Description

General description

Fully automatic, ready-for-connection compact booster unit consisting of a single pump unit and a buffer tank provides hygienic separation of drinking water and protects against non-drinking water of liquid category 5 according to EN 1717. Version without speed control:A fully automatic control system switches the pump unit on and off depending on pressure and switches it off depending on the flow. If the pressure falls below the preset pressure setting, the pump unit switches on and generates a constant pressure, the pump unit switches on and generates a constant pressure. With consumption decreases and the flow falls below the minimum flow rate, the pump unit switches off. The connection for dry-running protection is designed as a digital input. If the connection is open, the control unit switches off the compact booster unit after approx. 10 seconds (factory setting).Version with speed control:A fully automatic control system switches the pump unit on and off depending on the pressure.

CAUTION!Airbag formation in the suction lineCompact booster unit can not suck in any medium!

  • Install the pipeline rising

Fig. 2 Correct connection of the pipelineThe use of compensators with tie bars is recommended.

  1. Always install pipelines so that they are free of tension.
  2. Pipeline with discharge pressure lines with the distribution lines on the backed and discharge side.

Installation of pipeline compensator

DANGER!Sparks and radiant heat Fire hazard!

  • Take appropriate measures to protect the compensator during welding work in the vicinity.

CAUTION!Leaky compensator Flooding the installation room.

  • Check regularly for rips and blisters, exposed material or other defects.

The compensator is provided with a structure-borne sound insulation to intercept the length limitation to absorb any reaction forces.

  1. Install the compensator in the pipeline without tension.
  2. Fasten bolts equally cross-wise.
  3. Do not paint the compensator and always protect it against oil.
  4. The compensator has to be accessible on the compact booster unit at any time for inspection purposes and for this reason should not be included in the pipe insulation.
  5. The compensator is subject to wear.

Maintenance

General information/Safety regulations

HAZARDOUS VOLTAGE!Unintentionally switching on the compact booster unit

Danger to life !

  • The compact booster unit has to be voltage free for all repairs and maintenance work. (Pull out the electrical mains plug)
  • Secure against restart.WARNING!Inappropriate lifting/moving of heavy modules or componentsRisk of injury or property damage!
  • When moving heavy modules or components, use suitable transport devices, lifting devices and lifting accessories.CAUTION!Unqualified persons working on the compact booster unitRisk of injury!
  • Only let specially qualified personnel perform repair and maintenance work.CAUTION!Inappropriately maintained compact booster unit The proper function of the compact booster unit can no longer be ensured!
  • Maintain the compact booster unit regularly.
  • Set up a maintenance schedule for the compact booster unit that focuses especially on the pump lubrication, shaft seal and clutch.

The compact booster unit is assembled, commissioned, maintained, and shut down solely by sufficiently qualified and authorized personnel.

  • Always observe the safety regulations and instructions.
  • Observe the instructions for working on the pumps.
  • In case of damage, please contact our service department.
  • By setting up a maintenance schedule, the required maintenance to avoid expensive repairs and achieve fault-free and reliable functioning of the compact buster unit is held to a minimum.
  • Avoid any use of force in connection with disassembly and assembly.
  • During normal operation, no biological danger results from the compact booster unit.
  • Hazards might result microbiological contamination.
  • Please clean the buffer tank regularly with clean drinking water!
Monitoring Operation

CAUTION!Dry running causes increased wear Damage to the pump unit!

  • Never operate the pump unit when it is empty.
  • Never close the shut-off valve in the suction line and/or supply line during operation.CAUTION!Exceeding the permissible temperature for the pumped mediumDamage to the pumps!
  • Operation is not permitted with closed shut-off valves over longer periods of time (overheating of pump medium).
  • Observe the temperature values as stated in the data sheet and under technical data.

During operation observe and check the following points:

  • Compare the recharge pressure of the membrane pressure vessel to the recommended values.
  • Check the running noise of the roller bearings. Vibrations, noise, and increase in power consumption for consistent operating conditions are a sign of wear.
  • If available, observe the functions of the additional connections.

Maintenance schedule

Interval Measure
Min. once a year The pump and drive motor should run smoothly, the floating ring seals should not leak
Check if the shut-off, drain and check valves function properly and don`t leak.
Strainer in the pressure reducing valve, if applicable
Check the compensators for wear (if applicable).
Check the precharge pressure and, if necessary, check if the membrane pressure vessel leaks.
Check automatic switching.
Check the switch-on/off points of the system.
Check the water supply, recharge pressure, water shortage monitoring, and pressure reducing valve.
Check if the overflow is sealed and clean.

Set the recharge pressure

DANGER!Filling wrong gas in expansion vessel Danger of poisoning!

  • Only fill the pressure pad with nitrogen.CAUTION!Recharge pressure too high Danger of damaging the tank!
  • Observe the values as stated by the manufacturer of the tank (refer to type label or the tank manual).

The precharge pressure for the pressure vessel should be set to a value that is lower than the programmed switch-on pressure.Example: Precharge pressure 10% below the switch-on pressurePrecharge pressure of the membrane pressure vessel p = 0.9 x pEpE = switch-on pressure of the compact booster unit

RecommendationThese are average values. Experiments conducted on tanks have shown that the best storage volumes were achieved for pressures >3bar with a factor of 0.9 and pressures of <3bar with a factor of 0.8.

Example:pE = 5 bar: Recharge pressure 5 x 0.9 = 4.5 barpE = 2 bar: Recharge pressure 2 x 0.8 = 1.6 bar

Check the recharge pressure :

  1. Close shut-off valves under the membrane pressure vessel.
  2. Empty the membrane pressure vessel via the drain valve.
  3. Unscrew the protective cap of the valve on the membrane pressure vessel and store it
  4. Use a suitable checking device (eg tire-pressure gauge) to check the recharge pressure.
  5. Mount the protective cap of the valve on the membrane pressure vessel.

Fill the membrane pressure vessel 

  • Unscrew the protective cap of the valve on the membrane pressure vessel and store it
  • Refill nitrogen via the valve.
  • Mount the protective cap of the valve on the membrane pressure vessel.
Replace switching device
  1. Remove the power plug from the plug socket
  2. Pipework needs to be drained
  3. Close ball valve
  4. Loosen union not of the switching device
  5. Replace switching device
  6. Fill up pipelines
  7. Put power plug into the plug socket
  8. press reset-button on the switching device
