Peripheral Pumps

Peripheral pumps are economical pumping solutions designed to achieve high pressure with low motor power, particularly preferred in small-scale water pressurization and booster systems. ORFA Industrial offers a durable range of peripheral pumps from stock, developed for domestic use, garden irrigation, and boiler feed units. Thanks to their star-type impeller structure, professional peripheral pumps provide high discharge head, delivering efficient water transfer and compact design advantages with the assurance of ORFA.

What Are Peripheral Pumps and How Do They Work?

Peripheral pumps operate on a principle where the fluid moves along a peripheral channel within the pump body, increasing its energy. Compared to centrifugal models, these peripheral pumps can achieve high pressure values with much smaller impellers. ORFA Industrial recommends using peripheral pumps, especially in projects with low flow requirements but high pressure needs. Professional peripheral pumps, providing excellent vacuum when used with a foot valve on the suction line, deliver quiet and stable performance in residential booster systems. Thanks to their compact size, peripheral pumps offer easy installation in tight spaces, simplifying piping setup.

Peripheral Pump Types and Technical Specifications

Different peripheral pumps models are available based on application and motor voltage. The main peripheral pumps product groups in ORFA stock are:

Technical Grouping

  • Single-Phase Peripheral Pumps — 220V for household use.
  • Three-Phase Peripheral Pumps — 380V for industrial units.
  • Bronze Impeller Models — Resistant to scaling and corrosion.
  • Self-Priming Peripheral Pumps — With air venting feature.

Application Areas

  • Package booster sets for detached houses and apartments.
  • Small-scale garden and field irrigation lines.
  • Diesel and non-flammable light oil transfer.
  • Boiler feed and machine cooling systems.

Choosing the Right Peripheral Pumps and Efficiency

The success of a system directly depends on selecting peripheral pumps suitable for water consumption capacity and required delivery head. Incorrect selections can lead to motor lockup or insufficient water pressure. With ORFA expertise, you can determine the most efficient peripheral pumps configuration for your system, achieving high performance with low energy consumption. New generation peripheral pumps promise long-lasting use with corrosion-resistant body coatings and thermally protected motor structures. Professional peripheral pumps are the most efficient solution partner for low-cost pressurization projects.

Frequently Asked Questions

What is the difference between peripheral pumps and centrifugal pumps?

Peripheral pumps produce higher pressure at lower flow rates. Centrifugal pumps are suitable for transferring large volumes of water (flow) at lower pressures. Peripheral pumps are generally preferred for small apartment booster systems.

Why might peripheral pumps seize up?

Since these peripheral pumps are manufactured with very tight tolerances, the impeller may seize due to scaling if not operated for a long time. To prevent this, bronze impeller peripheral pumps models should be preferred.

How are peripheral pump prices determined?

Peripheral pumps prices vary depending on motor power (HP), impeller material used (brass/bronze), and delivery head capacity.
