An FRPP (Fiberglass Reinforced Polypropylene) jet pump is a type of pump that uses a jet of fluid to create a vacuum and pump liquid. This type of pump typically consists of two main parts: a jet nozzle, which is immersed in the liquid, and a diffuser, which is connected to the suction side of the pump.
The jet nozzle produces a high-speed jet of liquid that creates a low-pressure area or vacuum in the diffuser. This low-pressure area causes liquid to be drawn into the diffuser, where it is then pumped out of the pump.
The FRPP material of the pump is a composite material made of polypropylene reinforced with fiberglass. It is known for its strength, durability, and resistance to corrosion and high temperatures. It is an ideal material for the construction of jet pumps used in industrial and commercial applications where corrosion resistance is required, such as chemical and petrochemical plants, and wastewater treatment facilities.
FRPP jet pumps are used in a variety of applications and are often used to pump fluids that are not easily pumped by other types of pumps, such as fluids with low viscosity or high vapor pressure. They are also used for applications where a low NPSH (Net Positive Suction Head) is required, or for applications where the inlet pressure is too low to produce a sufficient flow. They are also able to pump the liquid even if the liquid surface is below the pump.
