Selection of Feed Pumps For Filter Press

A feed pump is a type of pump that controls the speed at which a fluid, such as fuel, moves. The low-pressure feed pump ensures a continuous supply of filtered fuel to the injection pump. The fuel pump is activated only when the engine is running. The most common feed pumps are centrifugal, screw, core, diaphragm, plunger, etc. Normally, most of the pumps used in industry are centrifugal pumps, which include ordinary pumps, stainless steel pumps, slurry pumps, slurry pumps, corrosion-resistant plastic pumps, etc.

What is a filter feed pump?

A typical filter and separation device used in mining, sludge, food processing, and other industries is the sludge press. Since the beginning of the 18th century, it has been widely used in the chemical industry, pharmacy, metallurgy, dyeing, food, brewing, ceramics, and other industries.

These feed pumps are high-pressure pumps and are basically of two types:

• Volumetric feed pumps
• Centrifugal feed pumps

A booster feed pump must normally be used with the coffee press. But how many different types of feed pumps are there? What are the guidelines for selecting a slurry pump? How do you choose a suitable feed pump for a coffee press? If you want to know how then keep reading the blog.

Features of Filter Press Pump:

Easy maintenance with replaceable parts:

These pumps are easy to maintain due to the feature of replaceability and interchangeability.

Specially designed for the positive suction head:

These pumps are specially designed on positive suction technology due to which they intake fluid from one side without reverting back. 

Long-life due to replaceable wearing parts:

Feed pumps have a long life cycle due to the replaceability factor as well as the factor of most latest and most robust design.

Working Principle of Filter Press Pump:

Filter presses are a pressure filtration method, so when the press feed pump increases the pressure, the particles build up in the chambers until they are completely full of solids. Once the chambers are full, the cycle is complete and the filter cakes are ready to be released. Many high-capacity filter presses also use high-speed automatic plate advances that speed up cycle times. Some filter presses are specially designed for fully automatic 24-hour operation in harsh environments such as mines or chemical manufacturing plants.

Filter presses operate in the direction of sludge pumping into the machine, so solids are evenly distributed throughout the cycle. Filter cake forms when solids build up on the filter cloth; the filtrate leaves the filter plates through the intersection ports to many and delivers clean filtered water.

Filter presses use a force filtration method so that when the press feed pump increases the pressure, the solids build up in the compartments until they are completely filled with solids and form a cake. The cycle is complete when the chambers are full and the filter cakes are ready to be released. Fast automatic plate feed is used in many higher-capacity filter presses to reduce cycle time. Some coffee presses are ideally designed to be fully automated.

How To Choose The Right Feed Pump:

While you are selecting a similar pump for the filter press you must be going through these 3 points:

1. Pump filter area:

It is important to know the filter area of ​​the coffee press used in the working environment, such as 50 m², 100 m², 200 m², 250 m², 300 m² and others.

Usually, the plump filter area is the main part for making the pump.

According to the request, the manufacturer adapts the range of the pump. When choosing a feed pump, the main part of the water press pump is the water press.

2. Pump connection ratio:

In accordance with the sludge provided. Customers should supply the gear ratio of the sludge to be transported after selecting the type of feed pump, and the manufacturers select the materials of the feed pump based on the variable.

3. Pump material:

Materials used in feed pumps include cast iron, common alloys, high chromium alloys, stainless steel and other materials. Unless the sludge is particularly caustic, a chrome alloy sludge pump is the most useful currently on the market. This type of material has some resistance to wear and corrosion. In addition, the service life is much longer than that of the iron pump, and the price is much lower than that of the stainless steel material.

Things to Consider Before Buying the Feed Pump:

Work pressure:

Most pressure pumps operate between 8 and 15 bar and for best results the pressure must be evenly distributed. You will need a pump that can handle your specific separation process and create the required constant pressure.

Secondary pumps:

Several positive displacement pump systems are often used in combination to develop the required pressure to operate the slurry pump. It is important to have the right overall system developed depending on the size of your plant and the processing that needs to be done.

Determine the pump stroke:

The higher the feed pump stroke, the better. When the actual filter pressure exceeds the pressure required for the filter press, the life of the filter cloth is often reduced.

Environment status:

If you work in an industry that has strict environmental protection laws, then choosing the right pump is important. You must keep hazardous material away from the environment. On the other hand, you have to keep external pollutants into the pump system. These must be taken into account when choosing a pump.

Pump capacity:

Knowing the type of fluids you will be using in the pump is one good factor. This will allow you to decide what type of pump you need. Then you need to determine the size and set up certain combinations of pumps. You need to determine how much you need to process per day, week, or year and use that information to select or build a pumping system that will give you the flow rate you need.
