What is an Open Impeller Pump? Why Is It Preferred?

Open impeller pumps are practical and durable products used in applications where fluid transfer is required. Their operating principle is simple: the liquid is drawn in through the pump’s suction line and, thanks to the open impeller inside, it is propelled outward by centrifugal force. In this way, the liquid is transferred from inside the pump to the discharge line.

The most important feature of this type of pump is its ability to operate smoothly even when the liquid contains solid particles. Thanks to its open impeller design, substances like pulp, shavings, vegetable, or fruit pieces do not obstruct the flow of the liquid. In addition, being made entirely of stainless steel allows these pumps to be safely used in areas where hygiene is essential. Their durability and hygienic construction make open impeller pumps indispensable across various industries.

Where Are They Used?

Open impeller pumps are especially preferred in areas where hygiene is a priority. Here are some common application areas:

Drinking water filling facilities
Surface cleaning of food products (such as vegetables, fruits, and fish)
Industrial washing machines (dishwashers and laundry machines)
Beverage production facilities (especially for beverages with pulp)
Transfer of coolant water containing particles (in glass, can, and metal production plants)
Pumping of sewage and sludge water
Biodiesel production facilities

In short, they can be reliably used for a wide range of liquids, from clean water to wastewater.

Open impeller pumps are used extensively, from drinking water filling plants to beverage production lines, from vegetable and fruit washing processes to industrial washing machines. They are also preferred in the transfer of coolant waters in glass and metal production facilities, the pumping of sewage and sludge, and even in biodiesel production plants. Wherever there is a need to transport liquids containing particles or requiring hygiene, open impeller pumps provide a safe and long-lasting solution.

Flexible Impeller Pumps: Precise and Efficient Liquid Transfer

For those seeking both efficiency and precision in industrial liquid transfer, flexible impeller pumps offer an excellent solution. Thanks to their self-priming design, wide range of applications, and compatibility with various fluid types, they are trusted across many industries.

What Is a Flexible Impeller Pump?

This type of pump features an eccentric-shaped housing and a rotor with flexible vanes. As the rotor turns, it creates a vacuum that enables the pump to draw liquid on its own. This eliminates the need for an additional suction system.

Working Principle

As the pump shaft rotates, the flexible vanes attached to the impeller bend upon contacting the narrower section of the housing. This bending creates a vacuum that draws liquid from the suction line. The fluid then moves through the pump body and is pushed out under pressure as the vanes bend again in the narrowing area. This continuous cycle enables a smooth and efficient liquid flow.

What You Need to Know About Centrifugal Pumps

Today, the safe and efficient transfer of water or other liquids from one place to another plays a critical role in many aspects of life. From homes to industrial facilities, from water treatment plants to power stations, there is a mechanical hero working behind the scenes: centrifugal pumps.

But what exactly are centrifugal pumps? Where are they used? And why are they so widely preferred?

What Is a Centrifugal Pump?

Centrifugal pumps are machines that move liquids by generating centrifugal force through rotational motion. The liquid that enters the pump gains speed through rotating impellers and is pushed outward, creating pressure. This pressure propels the fluid to its intended destination.

Where Are They Used?

Centrifugal pumps have a wide range of applications. They are not only found in large industrial plants but also in many everyday systems. For example:

Wastewater and treatment systems
Food and beverage production lines
Power plants

Even in some residential applications

This diversity is due to their adaptability to various operational needs.

Why Are They So Preferred?

Centrifugal pumps offer several advantages compared to other pump types:

High efficiency: They use energy effectively.
Quiet operation: A key factor in enclosed or indoor settings.
Easy maintenance: Components can be disassembled and reassembled with ease.
Compatibility with various liquids: Suitable for both clean water and waste fluids.
Resistance to a wide range of temperatures and pressures

In short, centrifugal pumps provide flexible, powerful, and reliable solutions in every respect.

Centrifugal pumps are the unseen yet essential components of modern life. When it comes to fluid management, they play a crucial role in ensuring both efficiency and safety.

Whether for a large facility or a small-scale system, choosing the right pump is critical for long-term success.

Pump Installation: Key Points to Consider

Archimedes’ invention, which is still present in our lives today as the Archimedean screw, continues to evolve and is used in many industries and areas. These pumps rely on the physical principles of lifting and compressing mechanical forces to raise water, transport liquids, and transfer from low pressure to high pressure. Pumps, which play a crucial role in the industrial world, must be installed correctly to ensure efficient operation. Pump installation plays a critical role in maintenance and efficiency. So, what are the key factors to consider during pump installation? Here are the fundamental aspects to keep in mind during the installation process:

Key Considerations for Pump Installation

Before starting the pump installation, there are several important points that need to be taken into account. These points can be summarized under the following headings:

Pre-installation Preparation
Determining the Location for Pump Installation
Pump Base (Foundation)
Suction Pipe Connections
Discharge Line Connections
Centrifugal Pump Electrical Connection

What Should Be Considered Before Installation?

Although the exterior of the pump is made of durable and hard materials, these materials can still be susceptible to damage. During the pre-installation stage, great care must be taken in the transportation and storage processes of the pump. Incorrect handling or storage can lead to damage to the pump. Therefore, it is important to ensure that the transportation methods are correctly applied before starting the installation.

It is recommended that the equipment to be used be coated with protective substances against corrosion. Also, if the pump installation is delayed, proper rust prevention materials should be applied to prevent the internal components from rusting (don’t forget to review the product’s user manual). The installation should be carried out in compliance with occupational safety regulations. Safety measures should not be neglected during the installation of the pump.

How Should the Pump Installation Area Be?

The area where the pump will be installed should provide enough space for operation, maintenance, and inspection. Especially for heavy pumps and large motors, lifting equipment such as a crane should be provided before installation. The pump should be installed in a location where there is no risk of freezing or explosion, where the ventilation system works properly, and the humidity level is low.

In addition, proper drainage systems should be in place to prevent water flooding and pipeline leaks. The use of drainage pumps or channels should be ensured for the proper evacuation of water.

Pump Base (Foundation)

The pump foundation is one of the most crucial stages of installation. The pump foundation must be prepared properly and made suitable for installation. Incorrect installation can shorten the pump’s lifespan and cause difficulties during maintenance. Adequate space should be left around the pump for maintenance and repairs. Additionally, the foundation must be heavy and durable enough to absorb vibrations. The foundation’s strength is essential to prevent misalignment of the frame and coupling.

Before the pump installation, it is important to ensure that the concrete foundation has fully solidified and gained strength. Concrete foundations are the most commonly preferred foundations for pumps and should be constructed on solid ground. Attention should be paid to the installation manual during the pump base setup.

How Should the Suction Pipe Be?

The suction pipe must be short and straight for efficient operation. If the suction pipe is long, the pipe diameter may be increased to reduce friction losses. If the pump will draw water from a lower position, the suction pipe must be continuously inclined upward. This will ensure the air in the pipe is discharged.

The suction pipe must be leak-proof and should be carefully inspected. If the pump draws water from a source at a much higher level, an axial isolation valve should be added to the suction pipe in a horizontal position. This valve should always remain fully open while the pump is operating. Additionally, there should be a distance between the suction pipe and the tank feed pipe. The tank feed pipe should be located farther from the suction pipe and below the water level.

What Should Be Considered in the Discharge Line?

The discharge line plays an important role in properly adjusting the flow rate and discharge height. A control valve may need to be added to the discharge pipe. It is important that this valve is located close to the pump. In the discharge line, a check valve can be placed between the pump and the control valve to prevent backflow.

If the pump discharge line is long and high, it must be protected against water hammer. To prevent backflow, a check valve should be attached to the discharge pipe. Also, when increasing the pipe diameter, a conical reduction should be used. The discharge line should be supported by the floor or ceiling in such a way that it does not stress the pump.

Centrifugal Pump Electrical Connection

Electrical connections during pump installation are extremely important. Only authorized electricians should carry out the electrical connections. Moreover, safety instructions must be strictly followed. Before starting the pump installation, it must be ensured that all power connections are disconnected. When laying electrical cables, care should be taken to ensure the cables do not come into contact with the pump or motor housing.

Before making the electrical connections to the motor, the pump shaft should be manually rotated to check whether the rotor turns smoothly. Also, grounding connections of the motor should be inspected. Electrical connections may vary depending on the motor’s power, power source, and connection type, so the necessary procedures should be followed.

Pump installation is a process that requires attention to detail at every stage. Therefore, all aspects to consider during pump installation are outlined in the user manual. To ensure the efficient operation and long lifespan of your pump, you should follow the steps outlined in the manual carefully.
