Peripheral Booster Pump

Peripheral pumps, also referred to as regenerative pumps (see also Side channel pumps), are centrifugal pumps with an impeller (see Peripheral impeller) that rotates within a largely concentric casing channel, featuring both inlet and outlet openings. As the fluid circulates repeatedly between the impeller and the casing channel, it gains significant energy transfer.

The fluid moves along the circumference from the inlet to the outlet of the casing, increasing in pressure. A stripper arranged between the outlet and the inlet prevents hydraulic short circuits between the high-pressure and low-pressure sides of the casing channel.

Thanks to the substantial increase in energy, peripheral pumps can be relatively small in size and are often designed as close-coupled pumps.

How does a peripheral pump work?

Functioning as a type of volume displacer pump, the peripheral pump operates by initially drawing liquid through a suction flange and directing it into an annular channel. Within this channel, the liquid encounters the peripheral impeller, which rotates and imparts a centrifugal motion to the liquid.

Upon exiting the pump through the discharge flange after traversing the annular channel, the liquid gains significant kinetic energy through the impeller's blades.

Difference between Centrifugal and Peripheral Pumps

Pump Purpose: If your primary need is for higher pressure, extended service life, and relatively simple maintenance, the centrifugal pump is probably the most suitable choice. These pumps are known for their robustness and efficiency in situations requiring constant flow and high pressure. In contrast, peripheral pumps, while more affordable and suitable for water lifts at significant heads, can experience problems such as turbine scaling if not used for an extended period.

Water Head: This is a critical factor in choosing your pump. If you need to pump water at elevations above 14 meters, a peripheral pump is more suitable, as these pumps are designed to work efficiently in these conditions, despite their lower flow rate. Centrifugal pumps, although powerful, may not be as efficient in these high-head situations.

Available Budget: Cost is an important factor in decision-making. Peripheral pumps are typically more affordable, costing up to half the price of a centrifugal pump. This price difference makes peripheral pumps an attractive option for applications with limited budgets, as long as they meet your specific needs in terms of pressure and lift.

When considering these aspects, it is important to remember that the choice between a centrifugal and a peripheral pump depends not only on a single factor but on a comprehensive evaluation of your specific needs, the operating environment, and the balance between cost, efficiency, and durability.
