FAQ

The rotor is suspended eccentrically in the pump house. Two lamellas are placed in the rotor which creates four large pumping chambers. The lamellas are guided by the cam discs in the pump housing, thereby causing a displacement of the product.

Also a lamella pump is a type of pump that uses a series of inclined plates, called lamellas, to move the product that needs to be pumped.

The product enters the pump and flows between the inclined plates, which causes the product to flow in an upward direction. As the product flows upward, it is forced through a discharge outlet at the top of the pump. The angle and spacing of the inclined plates can be adjusted to change the flow rate and pressure of the product being pumped.

Lamella pumps are commonly used in industrial applications for pumping thick, heavy products.

The unique construction of the JS lamella pump enables it to pump large and hard particles such as bones, tissues, and fat.

This makes it the exceptionally great for pumping raw material like animal by-product and industrial fish in the rendering industry. The pump can also handle cooked products before the liquids are separated.

Lamella pumps are particularly useful for pumping thick and heavy products, such as meat and bones. They are also used industrial processes where the product being pumped is abrasive or corrosive.

Lamella pumps are commonly used to substitute or replace other types of positive displacement pumps, particularly where the other pumps may be less efficient or may cause damage to the product being pumped.

Some examples of products that can be substituted with a lamella pump include:

• Gear pumps: Lamella pumps can handle higher-viscosity products and are less prone to damage from abrasives.
  
  
• Diaphragm pumps: Lamella pumps can be more efficient and may have a longer service life.
  
  
• Centrifugal pumps: Lamella pumps can handle higher-viscosity fluids and can often operate at a lower speed, reducing wear and maintenance.
  
  
• Piston pumps: Lamella pumps can be more efficient and may have a longer service life, particularly when handling high-viscosity fluids.

In general, lamella pumps are a good choice for applications where the product being pumped is thick, abrasive, or contains solids. They can also be a good choice where the pump may be subject to significant wear and tear, as they are designed to handle tough applications and require less maintenance over time.

The JS Lamella Pump does not require any manned operation, which reduces the risk of injuries.

The term "lamella" refers to the design of the impeller, which consists of two discs with angled fins or vanes that create a series of chambers.

The impeller rotates within a casing, drawing fluid into the chambers and then expelling it through the outlet.

The unique design of the lamella pump makes it well-suited for handling thick or viscous fluids, as well as fluids containing solids or abrasives. The other names used for lamella pumps generally describe specific features or variations of the design, e.g:

• Lamella Impeller
• Heavy-Duty pump
• Industrial pump
• Transfer pump
• Self-priming pump

Rendering is a process that converts waste / by-products from fish, pork, cattle, and poultry processing industries into stable, usable materials.

Materials like meat and bone meal, meat meal, poultry meal, blood meal, fish meal and animal fats and oils. These animal by-products are very useful as feed ingredients for livestock, poultry, pet food, aquaculture, and regular animal feed.

The rendering process involves heating and grinding by-products to produce a paste that can be used in a variety of products, such as animal feed and soap.

In the process Lamella pumps are used to pump the paste through the rendering process, which can include heating, mixing, and centrifuging.

The inclined plates of the Lamella pump create a centrifugal force that helps to separate the liquid and solid components of the paste, making it easier to process.

The Raw material, whether it is from pork, cow, or fish, is collected and accumulated in storage tanks.

When ready to be processed, the product is sized down through a crusher or transported directly for heating.

Traditionally this is done in a cooker which heats the product to a temperature where the bacteria are killed, and the liquids and fats are suspended from the solids.

Afterwards the product is compressed in a screw press which squeeze out the main part of water and fats. The remaining solids referred to as the press cake is then dried and milled to a flour.

The liquids are separated in decanter to get the water and oil. The oil is cleaned, and the water is used in the process again.

By-products are waste from the chicken, pork, cattle, and fish processing industry. Raw materials, which are not intended for human consumption, are rendered / transformed into stable, valuable, and useful materials like oils, various kinds of meal, proteins, and minerals.

The process covers drying the material and separating the fat from the bone and protein.

By-products are the waste / left-overs from processing of fish, pork, cattle and poultry. 

In general terms, by-products in food processing industries can come from various sources including:

1. Fruit and vegetable processing:
   By-products such as peels, seeds, and pulp are generated during the processing of fruits and vegetables into juices, purees, and other products.
   
   

2. Meat and poultry processing:
   By-products such as bones, skin, and fat are generated during the processing of meat and poultry into cuts, ground meat, and other products.
   
   

3. Dairy processing:
   By-products such as whey, which is a liquid remaining after the curdling of milk during cheese-making, and skimmed milk, which is a by-product of whole milk processing, are generated during the processing of milk and dairy products.
   
   

4. Grain processing:
   By-products such as bran and germ are generated during the processing of grains into flours and other products.
   
   

5. Fish processing:
   By-products such as heads, tails, and bones are generated during the processing of fish into fillets, fish oil, and other products.
   
   

These by-products are often rich in nutrients and can be used for various purposes such as animal feed, fertilizer, and even as ingredients in food products.

Food processing industries strive to reduce waste and maximize the utilization of by-products to promote sustainability and reduce their environmental impact.

The lamella pump is a specialized type of positive displacement pump that is widely used in the fishmeal industry. This pump has a unique design that allows it to handle viscous and abrasive fluids, such as fish slurry, with high efficiency and reliability. The lamella pump's design includes a series of closely spaced, interlocking lamellas that create a continuous flow path for the fluid being pumped.

In the fishmeal industry, the lamella pump is used to transfer fish slurry from the fish processing plant to the fishmeal plant. The slurry is a mixture of fish waste, water, and other processing byproducts, and it is typically very thick and difficult to handle. The lamella pump's ability to handle this type of fluid without clogging or causing damage makes it an excellent choice for this application.

The lamella pump's unique design also offers several other advantages in the fishmeal industry. For example, it can handle fluids containing large solids or chunks without damaging the pump or reducing its efficiency. Additionally, the pump can operate at high pressures, which allows for efficient transfer of the fish slurry over long distances.

Overall, the lamella pump is an excellent choice for the fishmeal industry due to its ability to handle viscous and abrasive fluids with high efficiency and reliability. Its unique design makes it an ideal pump for transferring fish slurry from the fish processing plant to the fishmeal plant, where it can be converted into valuable fishmeal products.
