How to pump food type dense and viscous fluids.
In this company is produced honey in an amount quite significant. The manufacturing process provides several steps. Only one is of our interest step, suction and the transfer of honey in order to obtain a product having the qualities required by demanding market. Some typical characteristics of honey complicate things, and make pumping operations particularly challenghing.
The first in order of importance is the viscosity, honey, even if subjected to a thermal conditioning process necessary for processing, remains a fluid relatively hard to pump. This peculiarity is the greatest difficulties to be overcome if you plan to transfer it by a pump.
The second characteristic of great importance is that honey is a delicate fluid. Due to its delicacy, honey requires appropriate treatment processes and typically “slow”, shaking, centrifugation or mixing at high speed are excluded, penalty the emulsion of the product, which is condition to be carefully avoided.
In the company for the operations of suction and transfer of honey were carried out by a self-priming flexible impeller pumps, which performed their jobs, but always with some complications.
Among the main problems that emerged, there was the poor capacity of prime due to lower the maximum number of revolutions to allow the pump to operate with viscous and delicate fluids like honey, the absolute necessity to prevent or inhibit the dry run operation to prevent damage to the impeller. The relatively frequent consumption the impeller certainly due to application too to the limit for that pump type.
Once we have been focused on the customer needs, we proposed a peristaltic pump HCP 25 equipped with mechanical speed variator and reinforced food grade hose.
Practical solution for honey pumping.
With the introduction of the new peristaltic pump in the production line , the problems encountered in the past have disappeared. The pump sucks and transfers easily honey of various origins and viscosity, low rotation speed , anyway adaptable (with the variator) avoids the formation of emulsions. The possible dry run operation is no longer a problem that require attention, the advantage of a better productivity is granted. The cleaning operations are simplified by the fact that it is no longer necessary to remove the pump or partially dismantle it as previously was in the past, the peristaltic pump HCP 25 has no mechanical parts in contact with fluid making impossible the contamination of the pumped product. The long duration of the tubular membrane has not requested so far no replacement.
