Description : In the food process industry, any kind of leakage in production equipment is unacceptable. Wasting product can be a major expense plus it creates unsanitary conditions in the plant. To solve this problem, traditional mechanical packing can be replaced with CinchSeal®
CinchSeal® a leading provider of sealing technologies, manufactures the CinchSeal®. The CinchSeal® is designed to prevent leakage in process equipment such as mixers, pug mills, screw conveyors and air locks.
Many equipment suppliers are providing CinchSeal® in place of the outdated mechanical packing. In 2003, a manufacturer of chocolate equipment supplied a major chocolate manufacturer in Pennsylvania with more than 30 pieces of equipment-all equipped with Cinchseals.
According to Drew Schmidt, President of Wm. A. Schmidt & Sons, “We chose Cinchseals for the new equipment because they are easier to install and simpler to maintain. The old style mechanical packing requires periodic adjustment, and can wear the shaft. If it is not properly and frequently maintained, the chocolate leaks out of the stuffing box. The CinchSeal®, on the other hand, has none of these issues. The shaft seal is one piece—split silicone elastomer that is static to the shaft— not multiple rings of packing—so installation and maintenance are easier and more cost effective.” With the addition of an air purge, extended seal life can be expected.
David Pitchko, President of CinchSeal®. explains the unique design of the Cinchseals. “The concept is to transfer the seal interface from the surface of the rotating shaft to a larger, self-lubricating and self-cleaning interface provided by the CinchSeal® module plates and rotor cup washers. The seal is an inherently low friction design.”
To ensure the best possible seal design for the equipment recently delivered to their customer in Pennsylvania, Wm.A. Schmidt & Sons worked closely with CinchSeal® engineering team. Ït was definitely a collaborative effort that included a lot of input and feedback from the chocolate manufacturer,” says Schmidt. “We are encouraging companies to replace the old packing seals with Cinchseals and offering the technical support and instructions on how to install the seal.
In addition to providing seals for the chocolate industry, Cinchseals have been used in applications including spices, chemical, aggregates and pulp. CinchSeal® is located in Pennsauken, N.J.

| Job : Material Loss Eliminated
Produced For : Vesuvius USA, Charleston, IL, manufacturer of ceramic slide gate valves for steel mill ladles for teeming.

Description : For the most of its twenty-year existence, Vesuvius put up with raw material loss and frequent shaft repair and replacement in its production line. The Vesuvius batching area mixes sand-fused alumina (Aluminum oxide) a nasty, granular, highly abrasive material that provides high wear resistance to the company's products. Its final mix is the material of construction for its valve line.
Vesuvius valves are noted for their success in the steel industry and other highly aggressive mechanical and chemical wear applications. Unfortunately, the characteristics of the materials that make Vesuvius valves, so resistant to abrasion, tend to eat any shaft packing and the shafts the materials come in contact with during production. Shafts and seals on screw augers required regular re-sleeving or replacement - often monthly. And when the packing and shafts deteriorated powdered alumina and other valuable materials ended up on the floor, contaminated and unusable.
Re-sleeving a shaft extended its life for only a few weeks, and required downtime during repair. When Vesuvius was able to wait for a bin change or a weekend to accomplish shaft re-sleeving or complete replacement, material loss and overtime costs increased. Vesuvius tried a variety of seals and packing alternatives, but all would be quickly destroyed by the raw material.
Solution
CinchSeal L.L.C. of Pennsauken, New Jersey recently introduced an unusual shaft seal that promised to eliminate Vesuvius' shaft abrasion and material leakage. As a plus, the manufacturer also promised reduced power consumption. Within the CinchSeal(tm) module (a compact polypropylene block), an elastomeric gland, secured by a spring-steel compression ring is applied to the shaft. The gland rotates with the shaft; the shaft does not rotate against it. The compression ring also spreads the gland laterally, establishing a freely rotating, sealed interface. The new seal transfers the seal interface from the shaft to a much larger surface of polished stainless steel plates and plastic rotor cups instead of grabbing the rotating shaft with packing or wastepacs, as is customary.
CinchSeal says that because the CinchSeal(tm) floats the rotor against the stainless stator, it accommodates shaft eccentricity and vibration without interrupting the powder seal or causing undue wear on the interface. This modular seal inherently provides self-cleaning and self-lubrication, so the seals actually operate dry. It accepts shaft diameter from 5/8 to 5 inches and will operate effectively in temperatures from 32° F to 500° F.
Result
Since the introduction of the first CinchSeal, Vesuvius has had no shaft failures and no seal failures. CinchSeals are now standard on all Vesuvius rotating equipment that comes in contact with high abrasive materials. Except for early minor corrections, material loss at Vesuvius has been completely eliminated, as has been its frequent maintenance. In periodic, scheduled maintenance, Vesuvius does precautionary replacement of seals, although the CinchSeal has never displayed the need for replacement.
Vesuvius has significantly reduced its maintenance time and maintenance costs and has eliminated the cost of lost material. |
