Printing ink pumps

Pump for transfer and dosing UV printing ink

This company prints 4-color industrial labels. The valuable oenological label represents the company’s battle horse, labels are produced in many varieties and in a very high quantity. For producing labels, modern printing systems are used, all systems are able to quickly adapt to different printing needs. Obviously large amounts of UV ink and solvents are used, also viscosity may vary.

The first transfer and dosing experiences of the inks were made with double-diaphragm pneumatic pumps, certainly attracted by the seemingly very convenient cost. But company realized in a short time that the cost of compressed air was far from irrelevant, the precise dosage of printing inks remained more desirable than certainty due the well-known difficulty in regulating the operation of pneumatic pumps. Another sensible disadvantage was that the diaphragm pump was not reversible, making the color change and cleaning operation particularly complicated and with considerable waste of time and precious printing ink.

The next step was to progressively discard pneumatic units and rely on a peristaltic pump to improve ink management. The benefits were immediately apparent, total energy costs cut, speed and precision in ink feeding and dosing. Great simplification in cleaning and changing ink colors since the typical peristaltic pump reversibility has made it possible to quickly empty the pump and line with simple counter rotation, ensuring great savings in the management of the various inks. However, there was still some aspect to be improved, the duration of the peristaltic tube, not entirely satisfactory.

During modernization of printing plants, the existing peristaltic pump was replaced with the most reliable Hose Carrier peristaltic pump HCP 20 complete with mechanical speed variation, but above all with the special synthetic fiber reinforced hose. The special reinforced peristaltic hose can ultimately guarantee the long operational lifetime, in addition to the great benefits of peristaltic system. Ink management has had such a significant improvement that in a short time an order for a second machine is followed.

Liquid egg and yolk metering pump (Egg products).

Liquid egg, and egg product easy an precision dosing.

In this pasta factory every year hundreds of tons of pasta are produced, to obtain such quantities, it has become necessary to introduce efficient and rational modern industrial processes. The use of semi-finished products such as liquid egg and egg products in the production cycle, makes possible to obtain the final product, more easily and with higher quality and safety criteria.

The already-shelled and pasteurized liquid egg from highly specialized suppliers has simplified the production process with great efficiency and very high quality levels. The use of highly specialized ingredients such as liquid egg and egg products ensures required levels of safety and hygiene, considering that egg is the most critical component in the pasta production process. Pasteurized liquid egg is an indispensable aid in a modern pasta production process, it is certainly necessary to treat it with a suitable machine to provide the correct dosage in the pasta production process.

Egg products perfect pumping solution.

For this purpose, a special HCP 15 peristaltic pump was introduced in the process pasta plant, completely made of stainless steel and equipped with a special peristaltic hose that guarantees the sanitary cleaning criteria necessary for this operation. To make a precise dosage possible, the pump is controlled by an inverter that can check the operating parameters for a complete integration into the overall automation of the production plant . However, the peristaltic pump can perform simplified operations even at manual level, with the keyboard controls and the fine adjustment potentiometer included in the basic version of the inverter.

The most important feature of the peristaltic pump is to have no mechanical parts in contact with the delicate product (liquid egg). The liquid egg remains solely in contact with the peristaltic hose making it impossible any contamination. Naturally the peristaltic hose can be sterilized with the most common sanitizing or autoclave processes. Of course the peristaltic pump is entirely made of stainless steel, including the base and support of the inverter, and is equipped with dedicated sanitary fittings. The peristaltic pump came into service in 2015, and is doing its job every day.

Peristaltic pump for honey

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.

peristaltic pumps for ceramic slip and glazes for the ceramic industry.

Peristaltic pumps for ceramic slip and glazes.

The production in the ceramic tile and brick industry exposes the pumps to a critical process: the highly abrasive nature of the ceramic slip and the high viscosity make it necessary to use appropriate handling technology to ensure efficient and cost-effective operation. For other fluids, such as glazes, pumps must also be provided with dosage pre-requisites for production cycle requirements.

HCP peristaltic pumps, robust, simple and adaptable, are the perfect solution for any type of pumping task in the ceramic production process. In a major ceramic company, years ago, a HCP 35 was bought for transfer of glazes, over time, two other HCP 50 pumps for the handling and transfer of slip were introduced to be used in a group affiliate. More recently, a new HCP 25 peristaltic pump has been supplied with inverter control intended for glazes transfer and pre-dosing operations.

Perfect for ceramic slip and glazes.

Hose Carrier peristaltic pumps are ideal for aspiration and transfer of ceramic slip and glazes, perfect for emptying or filling underground tanks, thanks to the perfect online reversibility without having to move the pipes. With HCP peristaltic pumps, it is easy to handle ceramic slip in a simple and cost-effective way, despite the high viscosity and abrasion of the material. In the ceramic industry, the Hose Carrier peristaltic pumps perfectly fit the mill loading and unloading operations, feed the atomizers, preparing and conveying ceramic slip and glazes, generic emptying and cleaning operations.

Costs? They remain low and easily under control, no repair at the workshop, no dead machine days, no specialized manpower, no pump removal from workin site, no pipe to remove. One replacement spare only (the hose), replaceable in the site in just a few minutes. No pump is easy to use, effective and simple to handle as a Hose Carrier peristaltic pump is.

Stainless steel peristaltic pumps.

Inox pumps? when using peristaltic pumps in stainless steel.

If there is a peculiarity that in principle distinguishes the peristaltic pumps from the others in general, it is the characteristic of being “contactless” This means there is no physical contact between the pumped fluid and the pump’s mechanical organs. The treated fluid remains entirely contained in the peristaltic hose. This peculiarity excludes, in fact, that materials that are compatible with the liquid to be treated must necessarily be used to make the pump as inevitably applies to all other types of pumps, often made in stainless steel.

What is the purpose of a inox peristaltic pumps, and what advantages are obtained?

Essentially, not many, there are no real practical advantages to make the difference between a common pump and one entirely INOX made . It is possible to make wider and different considerations than the search for a “functional” purpose.
We can consider the environment where the machine is to be applied, the environmental characteristics may still be chemically aggressive, so the pump would suffer “passively” the consequences.
Other environmental conditions require very high cleaning levels, the ability to intervene quickly on machines easily and effectively ensures the sanitary levels required by these situations. Sectors such as food, pharmaceutical and cosmetics are the most common example in which the highest level of direct and indirect cleaning is to be guaranteed. it’s not a casuality in these cases, entire machines and production lines are made using stainless steel in considerable quantities.

Other criteria that may determine the choice of using a stainless steel peristaltic pumps may be more subjective. Sometimes the customer chooses a peristaltic inox pump to make it easy to operate the machine’s normal handling and maintenance process, having the highest resistance to atmospheric or environmental impacts from the pump’s structural components. It is possible to say that a machine made of stainless steel makes it much simpler to perform more intensive and accurate cleaning operations (such as pressure and steam scrubbing) or facilitates the use and handling of the machine in the most extreme environmental cases , characterized by summary and corrective maintenance, or vice versa, very frequent and intense.

Finally, there are good reasons that make the choice to use a completely stainless steel peristaltic pumps substantially mandatory.
