The pump is a multistage self-priming Sterling SIHI type CEHA connected through anti-explosive flexible link with anti-explosive electric motor with ATEX certificate on a common metallic base, air-separator complete with check valves, by pass, security, spherical valves according to the EU directive PED 97/23.


The proposed distributors of TOKHAIM, WAYNE, EUROPUMP, comply with Greek legislation, meet ATEX requirements (NR 94/9/EC), are MID certified (NR 2004/22/EU), have communication capability with all the consoles used by the stations, have boards with LCD displays with Backlight, a supply of 45lit/min, and maximum operating pressure of at least 25 bar with an accuracy of 0.5%.


Multistage submersible immersion pump equipped with Bypass valve and manifold system for safe operation and easy maintenance.


An automatic fire detection and extinguishing system will be installed in the tanks. Over the manhole of the tank and at a height of 0,60m we manually place an extinguishing system which is activated by two anti-explosive heat-proof detectors.

The system consists of the fire panel, two anti-explosive heat-proof detectors that, in case they are activated, trigger the siren, strobe and extinguishing system. The fire extinguishing system consists of the bottle with the extinguishing material and the pipes over the manhole of the tank.


The system consists of a gas detection table of 4 zones and 4 anti-explosive heat-proof detectors that are placed near the distributor, the pump, the manhole of the tank and the filling point. The electrical installation of the detectors is anti-explosive.

Upon detecting the existence of an explosive mixture in any of the above points, the system is activated via the central control panel, thus closing pneumatic safety valves in the gas networks and the power supply of the installation, while the risk announcement siren is switched on.


The pneumatic security system consists of pneumatic engines that close the valves of the gas networks in case of an emergency. Remote-controlled valves are placed as close to the area of the tank as possible, as well as of the liquid and gas return phase pipes, of the filling network of the tank, and of the liquid and gas phase distribution dispenser tubes. These valves are switched off by either activating the extinguishing system, the explosive gas detection system or the emergency operating buttons.


LPG sealed Electronic Table, class IP 55. This table will be supplied by the General Table of stations as well as, the pumps of the tank, the magnetic net level meter, the electronic heads of the distributor, the lighting of the distributor, and controls the pneumatic safety valves. Attached to the table are the explosive gas detectors, which include fault testator diagnosis system, LCD color visualization displays and information of the user.

The basic visual indications of the table are:

  • Continuous indication of tank level
  • The status of the cathodic protection and measuring the potential difference
  • The rate of detection of explosive gases in each zone
  • The mode of the distributor and the pump
  • Protection against overfilling
  • Protect the pump from running dry

There is possibility of remote control of the panel as well as the entire plant via the Internet.


An Interlock system is installed in-between the station security system and the insecurity system of the tank. Therefore, during the delivery phase it equalizes electric charges so that there is no static electricity in the tank. If necessary the Interlock system switches off the valves of the tank. This system is built and certified according to ATEX.


A special sensor (bar) of suitable length is installed in the tank for measuring the level of gas and temperature. This sensor exceeds even the most demanding specification accuracy internationally, achieving excellent accuracy in fuel level change detection. This bar can also be used in the future to connect to any compatible input-output system of the station.


Our application is based on the most effective way of protection against corrosion of the tank located in the ground, the cathodic protection.
In this method, the tank is connected via a cable with one or more anodes. The anode is placed in the ground and is selectively corroded instead of the tank.

Thus, over time, it wears out while the tank is maintained intact. This way we achieve an extension of 5 years of checking the tank, achieving a large reduction in the cost of the five years control.

With the innovative application of our general table, we read the measurement of the cathodic protection through the LCD touch screen panel of the station.


All aboveground and underground networks are made of seamless steel pipes Sch80 in API 5L Grade B. All the accessories (bends, tees, elbows, couplings, nipples, contractions) will be steel, matching quality and standards to those of the pipe sections of networks in which they are installed.
