How to easily pump dense and viscous fluids.

Peristaltic pumps for very viscous fluids

viscous and dense fluids peristaltic pump100,000 cps, up to this value can reach viscosity of fluids that our customer, operating in the food sector, must transfer seasonally from reactor to containers prepared for the following Machining. The operation was carried out by flexible impeller pumps with very disappointing results and very high operating costs. The transfer of normal or viscous  products, obviously ,did not generate problems, but as the viscosity raise, difficulty, inefficiencies, and high management costs grew fast. The company reached a level that was no longer sustainable. The increasing viscosity of products generated great discontinuity  of suction flow to the pumps, often causing  destruction of the rubber impellers and mechanical seals of all the pumps available. Viscous and dense fluids = problems.

This is the fact, without any consideration for the long process  pumping times, combined with cleaning, restoring and continuous maintenance time spent for the various pumps involved . The  company technical manager finally decide to  seek a rational solution to solve the issue, he exposed the problem to several pump producers, proposing them a sample of the most difficult viscous product to verify the transferability. No one proposed a solution, 100000 cps are a limit for almost everyone. We made our own tests with our peristaltic pumps. After that we have realized that we could definitely eliminate the high viscosity transfering problems of this company.

The right solution for very viscous and dense fluids.

Now, a peristaltic HCP 50 pump equipped with special accessories has replaced the previous pumps in the suction and transfer operations. Our peristaltic pump is equipped with additional vacuum system and Inverter panel for the management of the speed variation. The possibility to change the speed allows the adaptation of the pumping capacity to the characteristics of most of the less problematic fluids. With the few high viscosity fluids, increased vacuum system allows to obtain the suction efficiency required, needed to work with high viscous products (up to 100000 cps).

The pump capability of realizing a vacuum up to 95% and the ability to keep it stable even with different speeds allows the HCP 50 peristaltic pump to satisfy the customer’s requirements for high viscosity fluids. Low operating cost and effectiveness in operation have consolidated the trust of our customer to our peristaltic pumps. We can expect the introduction of some other machine in future

Peristaltic pump for honey

How to pump food type dense  and viscous fluids.

peristaltic pump for honey and food grade fluidsIn 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.
