Efficiency and Quiet Performance Internal Gear Pumps

Internal gear pumps from Target Hydraulics are suitable for low to high-pressure applications. With a maximum pressure rating of 420 Bar, these pumps can assure you high mechanical efficiency, volumetric efficiency, and low-pressure pulsation.

Internal Gear Pump Manufacturer

An internal gear pump has almost the same working principle with the external gear pump. However, an internal gear pump features a unique design where two gears of varying sizes mesh together, enabling one to rotate within the other.  Specifically, the larger gear, known as the rotor, is an internal ear with teeth positioned on its inner surface. This rotor houses a smaller gear, called the idler, which engages with the rotor to facilitate the flow of fluid through the system as the gear turn.

If you are looking for an internal gear pump for your hydraulic system, Target Hydraulics is your best supplier. Our internal gear pump exhibits remarkable versatility and efficiency. Whether you need to pump thin liquids like solvents or thick substances like asphalts or adhesives, our pumps can handle viscosities ranging from 1cPs to over 1,000,000cPs. We also designed these pumps with ease of use, self-priming capabilities, and more.
