INDUSTRIAL PUMPS FOR SCRUBBERS

APPLICATION: INSTALLATION OF CHEMICAL PUMPS IN SCRUBBER PLANTS

The emission of gasses in the atmosphere is regulated by specific national and international laws that must be respected by all industries. The term “air treatment” refers to systems and techniques used by the industries to keep the air quality and the level of pollution under control.

Scrubbers are the easiest and most efficient systems for purifying the air by removing particulates and/or gasses.

There are several types of scrubbers which are used in different industrial sectors.

Plants

FLUIDS GENERALLY INVOLVED IN THIS APPLICATION:

Scrubbers are generally used to:

  • wash fumes (e.g. emitted by boilers or furnaces) with soda or other liquids, in order to remove hydrogen sulfide, hydrochloric acid, hydrocarbons and sulfur dioxide.
  • depurate gasses (e.g. washing synthetic gasses with monoethanolamine in order to remove CO2).

Scrubbers are generally used by:

  • petrochemical industries
  • chemical and pharmaceutical industries
  • galvanic industries
  • packaging industries
  • food industries
  • cellulose industries

INDUSTRIAL PUMPS INSTALLED IN AIR TREATMENT AND FUME DEPURATION SYSTEMS

scrubber

The polluted air is directed inside a chamber where it comes into contact with the washing liquid which transfers the pollutants from the air to the water. The purified air is released into the atmosphere while the polluting particles become an integral part of the washing liquid, which is then collected in a tank.

During this process, the polluted air goes from the bottom to the top while the washing liquid is pushed up by the use of centrifugal pumps and then it goes from the top to the bottom through the scrubber. The washing liquid collected in the tank is then recirculated by means of horizontal centrifugal pumps installed on the ground or through vertical pumps installed directly inside the tank. The pump continues to recirculate the same liquid which, after the transfer through the scrubber, returns to the tank.

SPECIFIC REQUIREMENTS FOR THIS APPLICATION: WHICH ARE THE BEST PUMPS FOR AIR TREATMENT AND FUMES DEPURATION SYSTEMS?

Additives inside the washing liquid are often hazardous chemical agents. For this reason it is necessary to use anti-corrosion pumps.

The pump used in this process can be installed next to the tank or vertically immersed in it.

In both cases, GemmeCotti offers suitable solutions:

Horizontal centrifugal pumps:
– series HTM PP/PVDF (magnetic driven)
– series HCO (mechanical sealed)
are the best solution for the installation next to the tank.

Vertical centrifugal pumps:
– series HV (monoblock)
– series HVL (with bracket)
are the ideal solution for installation with the pump immersed in the tank.

All these centrifugal pumps are made of thermoplastic materials PP or PVDF, which ensure a great chemical resistance to the chemical agents used in this application.

MAGNETIC HORIZONTAL CENTRIFUGAL PUMPS SERIES HTM PP/PVDF

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

HTM SP: OUR NEW MAG DRIVE CENTRIFUGAL PUMP SELF-PRIMING

HTM SP mag drive centrifugal pump self-priming

We are extending our product line: our new pump is ready!

We are happy to announce our new mag drive centrifugal pump self-priming HTM SP!

GemmeCotti HTM SP pumps combine the typical features of our mag drive centrifugal pumps with the self-priming capability. These pumps can prime up to 6 meters at sea level.

MAIN FEATURES

MATERIALS

HTM SP pumps are made of Polypropylene (PP), a thermoplastic material that ensures the best resistance to most chemicals.

All the internal plastic parts are obtained through the injection moulding process that we directly manage in our sister company Gemme Plast.

PERFORMANCE CAPABILITY

The new magnetic centrifugal pump self-priming HTM SP can reach a capacity of 25 m3/h and a head of 22 m.

The suction connection of this pump can be customized in 3 welded configurations according to your needs (frontal, on the right and on the left).

HTM SP curves

MAGNETIC DRIVE PUMP SYSTEM

Mag drive pumps have a special sealless design that is suitable for pumping corrosive and dangerous liquids thanks to the high chemical resistance and to the absence of leakage and emissions. The structure is really simple and it requires very little maintenance with consequent savings in terms of repairing, spare parts and machine downtime costs during the pump life.

In magnetic pumps, there is an external magnet which is connected to the shaft of the electric motor.
The synchronous motion is transmitted from the motor to the rotor (consisting of the internal magnet and the impeller) through the external magnet. The two magnets never come into contact, they are moved by the magnetic field only. The impeller connected to the internal magnet spins around a static shaft and the liquid moves through the pump. The whole hydraulic part is hermetically sealed: in the space between the magnets there is a rear casing which closes on the pump head and prevents the pumped liquid from coming out of the pump.

The pumped liquid must be clean, without solids in suspension (max. quantity of solids: max 2% – max 1mm).
