Selecting The Right Pump For Food Applications

Pumps in food industries are used to transfer product from one place to another and are one of the most important applications for food manufacturers. The texture and quality of food are one of the stringent parameters and it depends upon how the pump is used for food production and processing. The choice of handling and treatment equipment used in the manufacturing process and the selection of the right food processing pumps for food applications is essential. If you are not sure about how to select the right pump, or what information you should know before contacting the right vendor, here is a list of 5 things you should know when selecting the perfect pump for your industry.

#1. Processing properties

Before selecting the products, ask this question to yourself

What is the pump intended for?

Will the type of food product affect the working of a pump in long run?

Below are food properties that must be considered before selecting a pump.

  • Viscosity
  • Temperature
  • Specific gravity
  • Vapor pressure
  • Solids concentration
  • Abrasive or Non-abrasive

#2. Type of material

Will the food product be compatible with the pump materials?

Will it cause corrosion?

Each pump comes with chemical compatibility chart which will help you identify the most appropriate materials of construction for the pump.

#3. Does my plant require heavy duty pumps?

Yes, where downtime is not an option, heavy-duty pumps should be chosen. However if your plant is small and afford closing for maintenance, you may choose other pumps.

#4. Where will I install the pump?

If your answer is outside the factory you may require, special construction or installation considerations in case of both high and low temperatures. Ambient temperature may affect the quality of food.

#5. Flow rate and pressure

Your total volume and knowing how much time you have to move the fluid will determine flow rate. Pump differential pressure can be calculated by knowing pipe size (length & fittings), static lifts, and system equipment (filters, valves, etc.) friction losses.

By understanding the above factors, you will be able to make the right selection of pump. However, practically looking, the exact pump requirements depend on a lot of factors, including the nature of the product itself and the processes involved. However, they tend to fall into two types, those which can be pumped and transported in pipes and those which need to conveyed, usually by mechanical belts or similar systems.

We at Sujal Engineering, manufacture pumps that are suitable for all sorts of industrial applications. Two of the most commonly used pumps are:

Air Cooled pumps

It is a single stage, horizontal, single suction volute type, air-cooled centrifugal pump. These pumps are designed for high-temperature applications wherein they isolate liquid in the motor section of the unit for the hot process fluid in the pump casing with a series of pressure ports located in the front bearing housing or pump casing adapter. This isolated liquid (usually the same fluid as the pumped fluid) is circulated through an air-cooled heat exchanger by an auxiliary impeller located on the rotor assembly. This design allows the motor and bearing environment to be at a much lower temperature than the process fluid.

Advantages:

  • Standard motor insulation and bearings
  • Bearing environment at lower temperatures
  • Eliminates the concern of fouling caused by poor water quality
  • Secondary containment
  • Bearing wear monitors available

Applications:

  • Petro-Chemical
  • Oil Industries
  • Synthetic – fiber
  • Textile, dyeing, printing
  • Plastic and rubber
  • Paper making
  • Timber processing
  • Food
  • Construction

Centrifugal pumps

Centrifugal pumps are one of the most useful pumps which operate on the concept of centrifugal force and internal rotating mechanisms and is vital yet invaluable to a number of different industries. The liquid that leaves the outer diameter of impeller enters into the internal casing wall of volute. Here it stops to collect in ever-expanding exit chamber of volute. The velocity is now converted into the pressure available at the discharge nozzle because the impeller diameter and motor speed are constant. The centrifugal pump can be considered to be a constant pressure device.

Advantages:

  • Ease of operation: centrifugal pump will max out on pressure at its dead-head pressure. This will not cause any damage to the system and it is easy to say able to work at medium to low head
  • Accommodates large volumes of liquid
  • Is able to work for medium to low viscous fluid
  • Continuous pulsation free delivery
  • Less wear and tear in case of corrosive and abrasive liquids

Applications:

  • Agriculture
  • Water and wastewater
  • Sludge pumping
  • Beverage and Dairy
  • Pharma & Cosmetics
  • Power generation plants
  • Petroleum
  • Mining
  • Chemical
