Usage
The PDP series pressure booster stations are dual pressure booster stations with vertical, multi-stage high-pressure centrifugal pumps. The pressure booster stations are suitable for pumping service water or fully desalinated water without abrasive components. The units are factory-assembled and electrically wired ready to plug in. A diaphragm expansion tank limits the number of switching cycles and ensures pressure-dependent switching on and off without pressure surges. The high-quality stainless steel centrifugal pumps in industrial design guarantee many years of reliable operation. The delivery pressure is measured by an industrial pressure sensor. The sequence control is implemented using a LOGO! logic module with integrated LC display.
The units can either be installed directly as a stand-alone solution or used in conjunction with the extensive range of accessories. This allows them to be optimally adapted to the respective requirements.
The pressure booster stations are used where pressure can be increased with pressure hysteresis.
- Pumping water from storage tanks
- Pressure increase in tap water networks
- Pumping water from network separation tanks
Functionality
The pressure booster stations are designed for inflow operation with and without pre-pressure, as well as for suction operation with moderate suction height. A fully automatic, pressure-dependent control system regulates the switching on and off of the pumps. Smaller withdrawal quantities are fed into the network from the diaphragm expansion tank, which prevents the pumps from starting up too frequently. The pressure booster station must be protected against dry running by means of a suitable protective device (accessory). The dry running protection can be designed as a float switch, pressure switch, or electrode relay.
A collective fault signal can be tapped at the control system (potential-free changeover contact).
The pressure booster stations are electrically wired at the factory. The operating voltage is 400 V/N/PE, and the control unit is operated with low voltage (24 VDC). The pressure limits and the pre-pressure in the diaphragm expansion vessel may need to be adjusted to suit local operating conditions. The factory setting is indicated on the type plate.
