What is the working principle of hose pumps?

ELRO Peristaltic Hose Pumps are positive displacement pumps powered by an electric motor. Inside the pump, there is a semi-circular hose and a metal rotating part, called a shoe, that compresses the hose as it rotates 360 degrees. Pressure is created as the rotating shoe squeezes and releases the hose, allowing material to fill the hose. This process generates a peristaltic motion, providing suction and discharge. As the shoe rotates, the fluid accumulated in the center of the pump is discharged from the outlet. Each opening of the hose creates a vacuum, ensuring consistent suction. ELRO Peristaltic Hose Pumps are partially filled with a specially formulated oil designed to extend the hose’s lifespan. There is no contact between the oil and the fluid; the fluid flows entirely through the interior of the hose.

What are the purposes of use for ELRO peristaltic hose pumps?

ELRO Peristaltic Hose Pumps are ideal for abrasive, viscous, and delicate fluids. They are also used for transferring fluids containing particles and can handle particles that are up to 10% smaller than the hose diameter. Since ELRO Peristaltic Hose Pumps are positive displacement pumps, all the product entering the pump is transferred without loss. As there are no metal components in the fluid pathway, these pumps can operate safely in EX-PROOF environments. However, because they work with a motor and gearbox, these components must be specifically selected as EX-PROOF to ensure safe operation.

What are the processes in which hose pumps are used?

ELRO Peristaltic Hose Pumps are used in the chemical industry for the transfer and storage of adhesives, resins, paints, varnishes, inks, acids, alkalis, solvents, and alcohols due to their compatibility with many chemicals. They are also preferred for transferring sticky products due to their seal-less design. In the ceramics industry, they are used for glaze spraying and ceramic slurry transfer. In the food industry, they are preferred in filling and transfer units due to compliance with hygiene standards. In the cosmetics and pharmaceutical industry, they are utilized in filling and transfer units. In power plants, they are favored for their EX-PROOF feature. In the paint industry, they are highly effective for transferring viscous products. In the waste management industry, they are commonly used for sludge transfer and the handling of particulate products, thanks to their ability to transfer such materials effectively.

What are the material properties of ELRO peristaltic hose pumps?

ELRO Peristaltic Hose Pumps are manufactured with aluminum bodies, but the connection materials can be produced from aluminum, polypropylene, stainless steel, or brass. Additionally, for the hose material inside the ELRO Peristaltic Hose Pumps, the most suitable material selection must be made according to the fluid.

NR: Suitable for food, resistant to cold. Suitable for dilute acid and alkali fluids.
NBR: Suitable for alcohol and oil-type fluids and resistant to wear.
CSM: Resistant to chemicals and wear. Suitable for acids, alkalis, and paints.
EPDM: Resistant to chemicals and has good insulation properties. Suitable for acid, alkali, and hot water transfers.

What are the capacity and other operating parameters of ELRO peristaltic hose pumps?

ELRO Peristaltic Hose Pumps generally have a maximum capacity of 46 m³/h. They are capable of suction from a distance of 9 meters and can operate with a maximum discharge pressure of 13 bar, allowing them to work comfortably under high back pressure. They can transfer fluids with viscosities up to 80,000 cPs. These pumps are capable of dry running. The maximum operating temperature depends on the hose’s temperature tolerance, and it is +80°C.

The mobile version, the T300 series, has a maximum capacity of 18 m³/h and a maximum discharge pressure of 1.5 bar. It is available with electric, diesel, or gasoline options, depending on preference.

What are the advantages of ELRO peristaltic hose pumps?

ELRO Peristaltic Hose Pumps have several features that provide advantages to users:

All series use a special oil, which ensures that the pump operates without the hose needing lubrication, saving time. This oil also minimizes deformation caused by friction, thereby extending the hose’s lifespan. All ELRO Peristaltic Hose Pumps are equipped with a shaft, which directs power from the motor to the shoe without stressing the hose. This prevents fatigue, protects the pump from impact, keeps it balanced, and extends the motor’s lifespan. In the IP and XP series, the hose contains another internal hose that expels air, allowing the hose to expand, creating a vacuum and enabling the suction action. This reduces the time it takes for the hose to expand and contract. The IP series also offers an optional early warning system that activates and provides a signal when the hose starts to wear. ELRO Peristaltic Hose Pumps allow for bidirectional operation and can be mounted in any direction, ensuring the most accurate positioning for your processes.
