Do you know that GemmeCotti pumps can be used in car washing machines?

pumps in car washing plantsGemmeCotti 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.

Our experience in car washes

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

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.

How does a mag drive rotary vane pump work?

In a magnetic drive rotary vane pump two pumps design are combined together: the sealless magnetic coupling and the positive displacement system with vanes.

With the magnetic coupling the torque is transmitted through contactless magnetic forces from the external magnet which is coupled to the motor shaft to the internal magnet which is connected to an impeller or rotor. This design ensures a hermetic and reliable separation between the pump and the motor making it the best solution when pumping chemicals and acids because it prevents leakage and emissions.

A rotary vane pumping system consists of vanes mounted in a rotor that rotate inside a cavity. When the rotor moves thanks to the above mentioned mag drive system, the vanes slide into and out of the rotor creating vane chambers that do the pumping work.
