SPECIFIC REQUIREMENTS FOR THIS APPLICATION: WHICH ARE THE BEST PUMPS FOR TANKERS OFFLOADING?

The right pumping solution for unloading and transferring dangerous liquids from vehicles (trucks or railroad tank cars) is selected according to the chemical compatibility and the requested performances.

GemmeCotti pumps are the best choice to transfer dangerous or hazardous goods, i.e. all the substances which, due to their peculiar properties, could be harmful for the environment or the people involved.

These liquids are classified according to their characteristics and degree of danger. In Europe, the transportation of toxic chemicals is regulated by specific laws:

ADR: agreement concerning the international transport of dangerous goods by road
RID: international carriage of dangerous goods by rail
ADN: carriage of dangerous goods by inland waterways

GemmeCotti is proud to offer pumping solutions for the safe handling of chemicals: we supply chemical pumps suitable for the safe offloading of the great majority of dangerous or hazardous goods.

Fluids generally involved in this application:

ammonia

HOW TO AVOID THE RISK OF DRY RUNNING DURING THE PROCESS OF TANKERS UNLOADING?

To prevent damages to the pumps due to the lack of liquid, GemmeCotti supplies the dry running protection device. This device is particularly recommended during the operations of tanker unloading and for all the applications in which there is the risk of liquid shortage.

Thanks to the adjustable threshold and timer, it is possible to set up the minimum power and operation time of the device. If the power is lower than the set value, the pump will automatically stop.

Main features of the dry running protection device:

Single Phase CURRENT RELAY

Multirange 15-35A

2 set points MAX / min

Also for motors with INVERTER

MAGNETIC DRIVE CENTRIFUGAL PUMPS AND MECHANICAL SEAL PUMPS

It is fundamental to choose the right pump model when dealing with acids or corrosive liquids. For the operations of tanker unloading, GemmeCotti suggests the use of mechanical seal centrifugal pumps or magnetic centrifugal pumps. The type of pump is selected according to the liquid to be pumped and to the requested working point.

MAGNETIC DRIVE CENTRIFUGAL PUMPS

Mag drive pumps have a sealless design that is particularly suitable to pump corrosive and dangerous liquids; the magnetic design together with the usage of anticorrosive materials, guarantees the high chemical resistance and the absence of leakage and emissions.

Moreover, the structure of magnetic drive pumps is really simple and requires very little maintenance with a consequent saving in terms of repairs and spare parts expenses during the pump life. The external magnet placed on the drive shaft transmits the motion to the internal magnet connected to the impeller, which rotates and moves the fluids through the pump.

MECHANICAL SEAL PUMPS

Mechanical seal centrifugal pumps are the best solution when the liquid has solids in suspension: their design with open impeller permits to transfer dirty liquids and fluids with high viscosity.

The seal of these pumps is composed of a static ring and a rotating ring placed on the pump shaft, which is directly coupled to the motor shaft. When the pump is working, the two rings’ surfaces slide together and the lubrication of the parts is granted by the pumped liquid.

GemmeCotti supplies pumps for chemicals suitable for the offloading process of tanker trucks, petrol tankers and railroad tank cars. Our industrial pumps allow you to unload the fluids with the maximum efficiency, ensuring safety, reliability and saving in terms of repairs and spare parts expenses.

Upon request, GemmeCotti pumps can be supplied with single phase motors and in ATEX version for potentially explosive areas.

GEMMECOTTI ATEX PUMPS: THE EM SERIES

8 April 2021

GemmeCotti supplies ATEX pumps for potentially explosive atmospheres. Our ATEX EM series are suitable for ZONE 1 II2G and ZONE 2 II3G classified areas.

What does ATEX stand for?

ATEX is an abbreviation for the French term “ATmosphères EXplosibles“, which translates to “Explosive Atmospheres” in English. It refers to the European Union’s directives for regulating equipment and protective systems intended for use in potentially explosive atmospheres. These directives aim to protect workers from the risks associated with explosive environments.

What is the ATEX standard for the EU?

The ATEX standard for the EU is actually a set of directives that aim to protect workers from explosion risks in hazardous environments. There are two main directives, all our pumps comply with the technical and safety requirements of ATEX Directive 2014/34/EU
The Directive states that the manufacturers of equipment intended for use in potentially explosive atmospheres shall draw up a written declaration of conformity of these products.

How are the ATEX Zones classified?

The term “ZONE 1” indicates an area where an explosive atmosphere consisting of a mixture of air or flammable substances (gas, vapour or mist) is likely to occur in normal operation occasionally.

The term “ZONE 2” indicates an area where an explosive atmosphere consisting of a mixture of air and flammable substances (gas, vapour or mist) is not likely to occur in normal operation. If it does occur, it will persist for a short period only.

Covid-19 emergency and 2021 trade shows: GemmeCotti’s update

15 October 2020

Despite the severe lockdown and the health and safety measures, the world is still dominated by the COVID-19 pandemic. In Italy as all over the world, the number of cases is increasing and the preventive actions don’t seem to be enough to avoid a new outbreak. The daily distressing news about the disease spreading suggests that we are really far from the end of the emergency.

Considering this dramatic situation, GemmeCotti decided to cancel its participation in all the 2020/2021 international trade shows, including the important pumps exhibition ACHEMA 2021.

Health and security are a priority for GemmeCotti and we don’t think that at the moment taking part in an exhibition abroad is safe enough for our team and our stand visitors. For this reason we are arranging a new way to show our products and factory in all safety.

We set up a think tank to update our strategies in order to connect with our customers: we are thinking about useful solutions to cross the time and space limits of traditional marketing activities.

The global situation is forcing us to rethink the concept of “trade show”: we are working on a plan of action that brings together physical space and digital communication to reach our partners directly and efficiently.
