Blood with suspensions of slaughter waste scrap, aspiration and transfer.
Probably blood and slaughter waste aspiration and transfer may seem a trivial aspect in a production process, but working with 200 tonnes of fresh meat, even with the aid of automated systems and very modern technological processes, a small annoyance can also become a more serious problem. And so, this modern company involved in slaughter and processing of meat, had a weak point.
The company has never been able to find a pump that is truly reliable for the suction and transfer of the blood of processing slaughter waste. The two plants of recent introduction were equipped with such pumps. But as always happens, the solutions adopted initially by designers are mainly of economic nature, and in a short time, the user pays the consequences. Find technical correct solution is in charge of final user. The pumps of the first plant lasted an insignificant fraction of time. Were replaced with a pneumatic diaphragm pump. The system improved its efficiency, but often happened a stoppage of the pump due to the blocking of the valve system, due to the input of a solid suspension largest or the formation of blood clots.
This fact imposed disassembly and cleaning of the seats and the valves to restore operation. Great discomfort, given that it is necessary to remove the pump and the pipes in order to perform this operation. The compressed air also has it cost, and on pneumatic pumps, even if the mid-pump size makes itself felt significantly. Sometimes, during priming phase, the diaphragm pump did not work due to the dirt which tends to settle in the seats valve preventing the operation. Ultimately, not big problems, but annoying drawbacks were frequent.
We were asked how to solve the problem, so we proposed a HCP 40 peristaltic pump with small footprint and very compact, in accordance to the requirements of the customer. And on 2014 the peristaltic pump has been installed in a small destination space. Since then, the peristaltic pump makes his daily work, transfering blood and slaughter waste with constancy and reliability, till today, the pump has not requested any spare and no maintenance intervention.
A company belong to an important group operating in the production of die castings in aluminum, needed a rational system for the management and recovery of the release agent, and lubricants used in the steps of molding the cast components. Each machine has a collection tank that of a few centimeters in height size, however, may contain several hundreds of liters of contaminated feed materials to be recovered and treated. Each tank was equipped with a submersible pump of the conventional type. Of course, because the height of the collection tank is of a few centimeters, were used submersible pumps for clean water to obtain a suction level as low as possible, obviously, hydraulics of such pumps, is not suitable for the transfer of contaminated fluids and with solid substances in suspension. In addition, the pump worked most of the time with the engine in the air without cooling. This situation has caused the inevitable destruction of a large number of submersible pumps. The increasing costs and the continuous functional uncertainties have made necessary the total rethink of the process of recovery and treatment of the release agent.
Among the various solutions available, was chosen to produce a new plant which involved the use of a Pump Hose Carrier HCP 5.0 that sucks in a centralized manner by a suitable collector provided with pipes arranged in each collection tank, the large capacity of the pump suction hose carrier HCP 5.0 would have produced the vacuum inside the collector every time is necessary to empty the tub, it would have sufficed to open the appropriate valve arranged. The plant was built on the occasion of the summer stop and is regularly entered in function to the reopening of the productive activity. The solution adopted has produced immediately significant positive effects. Not only the Pump Hose Carrier HCP 5.0 was able to produce a great suction effect, but thus made possible to aspirate the solid suspensions present in the release agent that for their nature is not possible to deal with submersible pumps. Of course the Hose Carrier pump is not affected by a possible dry operation or discontinuous. We would also point out that between the aspiration point , and the point where is located the pump, there is a distance of over 150 meters and six meters of altitude. The cost of the management of the pump is a tubular membrane per year, really negligible.
On the occasion of a definitive rethinking of the implant, verified on the field the validity of the solution chosen, were introduced some practical automations to the system of the manifolds in suction. The Pump Hose Carrier HCP 5.0 has been replaced with the largest HCP 6.5 with variable speed equipped with integrated inverter with automation provided for the final implant for release agent.
The “old” HCP 5.0, is now placed to the treatment plant of the separating fluid in the implementation phase, and the recovery and the transfer of the muddy substances produced during the manufacturing process.
I’m interested but without obligation, keep me informed
