On 19th June the international exhibition for the chemical industry ACHEMA 2015 ended now it’s time to sum up the results of our participation. We decided to present a sample of each pump type so that the visitors of our stand could have an idea of our manufacturing capability: from the sealless magnetic drive pumps (centrifugal, vane and turbine pumps in plastic and metallic materials) to the mechanical seal pumps and vertical centrifugal pumps. Needless to say that the extremely positive feedback and the enthusiasm shown by customers and potential customers for our pump was more than what we expected.
Our Managing Director Mr Enrico Gemme after the exhibition commented: “Achema 2015 has been a huge and unexpected success. We got many new contacts interested in our pumps and we truly believe that in the next months we would be able to expand our business in new countries making GemmeCotti a leader worldwide in the field of chemical pumps”.
To safeguard magnetic drive pumps against damage caused by insufficient liquid, GemmeCotti offers the Emirel A1-13-Y dry-running protection device. Specifically designed for these pumps, this device prevents dry running, closed discharge, and blocked suction scenarios. Its adjustable threshold and timer allow for customization of minimum power and operational time settings. If power falls below the set value, the pump is automatically stopped, ensuring protection. This device is especially valuable during tanker unloading operations and in any application where liquid shortage poses a risk.

What happens when a pump runs dry?
When a pump works without fluid there is a sudden increase of the internal temperature with destructive results of some pump parts. For example, when a plastic pump (in PP or PVDF) runs dry, the main damage occurring are:
1- the shaft in ceramic may break due to a thermal shock.
2- the rotating bushing may block on the shaft.
3- melting of some plastic parts (impeller, rear casing, internal magnet etc.) due to the sudden temperature rise.
How is it possible to prevent dry running?
To avoid the inconvenience of the dry running you can simply install a dry running protection device which stops the pump immediately in case of danger of dry-running. As a matter of fact, the device checks constantly the active power of the motor, which is the minimum value of the instantaneous power absorbed by the pump, through the reception of information about the voltage, the cosφ and current variations. Through a set point and a timer, which are adjustable, it’s possible to set the minimum power and the triggering time of the device. If the power goes under the established value, the pump stops and the device must be switched on again manually. In case of continuous intervention on the apparatus, check the presence of liquid and/or the correct functioning of the plant to find the cause of working of the device.
The international exhibition for chemical engineering and process industries ACHEMA 2015 in Frankfurt has just started and our personnel is ready to meet you at our stand HALL 9.0 B58. You can see the complete range of pumps and have the chance to talk to the General Manager to find out the best pumping solutions for your applications.
Don’t miss the chance to visit our stand HALL 9.0 STAND B58 at ACHEMA 2015!
This important international exhibition for chemical engineering and process industries will take place from 15th to 19th June 2015 in Frankfurt (Germany). Meet us there and you will have the chance to see the entire chemical pump production and to find out more about our new products such as for example centrifugal mag drive pumps series HCM with capacity up to 130 m3/h, mag drive vane pumps model HTPdesigned for high differential pressure and very low temperatures and portable pump model H-IBC suitable to unload tank trucks IBC containers.
Mag drive centrifugal pumps series HCMare made of thermoplastic materials (PP or PVDF) and are highly resistant to chemicals, pressure and temperatures thanks to the strong structure of the pump head which is machined from a solid block.
Mag drive vane pump series HTP are made of stainless steel AISI316 and are suitable to pump hydrocarbons, cryogenics, radioactive liquids and other chemicals. The mag drive design allows a safe work without risks of leakage and emissions.
Portable pump series H-IBC is a mag drive centrifugal pump in plastic which is place in a structure that you can move easily.
2015 is a very important year for us since the city of Milano, which lies few kilometers south of our factory, will host the Universal Exhibition EXPO MILANO 2015. From 1st May to 31st October the city will become the global showcase where participants from all over the world will exchange ideas and solutions on the main theme of the exhibition: FOOD.
GemmeCotti wants to offer the unique chance to meet us at our factory in Ceriano Laghetto and to get to know better our pumps while you are in the area to visit Expo. We can help you during your stay, supporting you with transportation and hotel reservations. Contact us at least two weeks before your trip to Italy and we will be glad to organize a meeting with you and to welcome you at our factory.

GemmeCotti pumps are used in many industries for different applications among which also car washing plants. Chemical pumps in car washes are installed with the main purpose of dosing and spraying water containing detergents and chemicals of various kinds through high-pressure jets. So it is necessary to use an efficient and reliable high-pressure pump to guarantee clean and shiny vehicles.
We have a lot of experience in this particular field and recently we have worked on a new project which required a pumping equipment with very high pressure for a wheel rim cleaning system in a car wash machine. The customer required a pump suitable to transfer a detergent from a 40-liter-tank to the oscillating jets of the machine. The fundamental requirement for the pump was the discharge pressure which had to be at least 6 bar. We studied carefully the application and in the end we proposed our metallic rotary vane pump series HTP that can reach a maximum pressure of 13 bar.
High pressure vane pumps for car washing machines
The pump model HTP that we selected for the application is a positive displacement pump with vanes made of stainless steel AISI316. In this pump the vanes in graphite are mounted in a rotor and they move inside a cavity sliding into and out of the rotor. In this way the fluid is pumped outside the pump with a pressure up to 13 bar and a maximum flow of 2000 l/h. Click here

to watch how a vane pump works.
Vane pumps model HTP in AISI 316 are suitable for detergents, hydrocarbons, solvents, heat transfer oils, refrigerants and cryogenics or other thin no-lubricating liquids. Thanks to the mag drive design these pumps are useful for low flow and high pressure applications such as car washes, pilot plants, sampling, flushing of mechanical seals and cooling units.
