Introduction
Fluid transfer is a vital process at the core of any industry where liquids need to be moved between different stages of production – in food and beverage production, chemical production, energy, and general industry. An efficient, cost-effective, and reliable fluid transfer pump is essential to move fluids and other materials from one point to another.
Along with other specialized equipment, pumps ensure controlled and efficient transfer when chemicals, water, or cooling fluids are moved from one container or location to another within the manufacturing facility. Selecting the right pump for the process and conditions is key to reliable and efficient production.
How Liquid Transfer Pumps Work
Many types of pumps can be used as transfer pumps. All are designed with the same general operating
principle: to move liquid from point A to point B by creating a difference in pressure that draws fluid into
the pump, then pushes it out again. Pumps transfer fluids by creating pressure differences, essentially
"pushing" the liquid from one location to another through a piping system. In this way, they use
mechanical energy to move fluids like liquids, gases, and slurries across different parts of a production
process.
Factors in Process Liquid Transfer Pump Selection
The ideal type of transfer pump depends on the application requirements, such as the need for high flow rates or for precise fluid control or for underwater operation.
Important factors to consider when selecting a pump include:
- Fluid type – Viscosity, corrosiveness, temperature
- Flow rate – Volume of fluid needed to be transferred per unit time
- Pressure – Pressure needed to overcome system resistance
One of the main challenges for transfer pumps is high-viscous liquids, so precautions must be taken to ensure that the pump motor is not overloaded. Viscosity changes when temperature changes, and materials become resistant to flow when they get cold. It is important to consider the temperature range when selecting and sizing a transfer pump.
Grundfos Pumps for Process Liquids Transfer
Depending on the specific liquid and properties (such as viscosity, flow rate, and potential hazards),
various types of Grundfos pumps are used for liquid transfer. An optimal pump solution may require end
suction, inline multistage, horizontal split case, immersible, or dosing pumps.
Grundfos End Suction Pumps for Process Liquids Transfer
Several Grundfos end-suction pump models are recommended for liquid transfer. These centrifugal pumps usually feature an impeller, and suction comes in from one side of the unit and water is discharged from the top. The VL and VLS series are recommended where applications require a vertical mount for the smallest footprint.
Grundfos Inline Multistage Pumps for Process Liquids Transfer
For process liquids transfer installations where high head is required, Grundfos inline multi stage pumps
are ideal. The modular design of the CR pump range adapts well to a broad variety of applications.
Grundfos Horizontal Split Case Pumps for Process Liquids Transfer
Grundfos KP pumps are also a workhorse for liquid transfer. These single-stage, between bearings, split
case pumps are specified for a max head 263 ft.
Grundfos Immersible Pumps for Process Liquids Transfer
For some liquid transfer applications involving tanks or containers, an immersible pump is an ideal solution. The pump itself can be immersed in the pumped liquid. Grundfos immersible pumps compact pumps typically mounted on top of or inside tanks or containers.
Grundfos Dosing Pumps, Systems and Tank Stations
Both mechanically and digitally controlled dosing pumps are used for reliability, durability, and accuracy
in liquid transfer processes. Digital dosing pumps allow smooth, continuous dosing and efficient
processes.
Grundfos also offers dosing tank stations for storing and dosing liquid chemicals in a precise, controlled
way, as well as complete dosing skid systems.
