What is IPS internal gear pump?

Introduction

The IPS internal gear pump is a vital component in various industrial applications, known for its efficiency and reliability. This pump stands out due to its unique design and operational mechanism, which offers several advantages over other pump types. In this article, we will delve deep into the IPS internal gear pump, exploring its structure, working principles, applications, and the benefits it brings to modern industries.

One noteworthy series in the realm of internal gear pumps is the KHG Series Internal Gear Pump. This series exemplifies the advanced technology and engineering behind modern internal gear pumps, offering enhanced performance and durability.

Understanding IPS Internal Gear Pumps

An IPS internal gear pump is a type of positive displacement pump where the fluid is moved by the action of gears. It consists of two gears: one smaller, internal gear and one larger, external gear. The internal gear is eccentrically mounted within the external gear, and as they rotate, they create voids that draw in fluid and then expel it, resulting in a smooth flow.

The design of internal gear pumps allows for a compact and efficient mechanism that is capable of handling various viscosities, making them suitable for a wide range of industrial fluids. The KHG Series Internal Gear Pump is specifically engineered to optimize this design, providing superior performance in demanding conditions.

Key Components and Design

The IPS internal gear pump's main components include the rotor (internal gear), idler (external gear), crescent seal, pump casing, and shaft. The crescent seal fills the gap between the two gears, preventing fluid from leaking back from the discharge side to the suction side.

In the KHG Series Internal Gear Pump, these components are manufactured with precision to ensure tight tolerances and minimal internal leakage, resulting in high volumetric efficiency. Materials are carefully selected to withstand the operational stresses and the nature of the fluids being pumped.

Operational Mechanism

The operation of an IPS internal gear pump involves the following steps:

• As the gears rotate, the cavity between the gears increases on the suction side, creating a vacuum that draws fluid into the pump.


• The fluid is trapped between the gear teeth and the pump casing, moving from the suction side to the discharge side.


• On the discharge side, the cavity decreases, forcing the fluid out of the pump.

This smooth and continuous flow is a hallmark of internal gear pumps. The KHG Series Internal Gear Pump capitalizes on this mechanism to provide consistent and reliable performance.

Advantages of the Internal Gear Design

The internal gear design offers several advantages:

• Low Pulsation: Provides a smooth, non-pulsating flow, reducing system vibration and noise.


• Self-Priming Capability: Can operate efficiently without the need for priming, enhancing operational readiness.


• Versatility: Handles a wide range of viscosities, making it suitable for various fluids, including lubricants, fuels, and chemicals.


• Compact Size: Offers a high power-to-size ratio, saving space in system designs.

Applications of IPS Internal Gear Pumps

IPS internal gear pumps are used across multiple industries due to their robustness and versatility:

• Chemical Processing: Ideal for handling aggressive chemicals and fluids with varying viscosities.


• Oil and Gas: Used in the transfer of crude oil, lubricants, and fuel oils.

Maintenance guidelines provided by manufacturers like the KHG Series Internal Gear Pump should be closely followed to ensure longevity and reliability.

Troubleshooting Common Issues

Understanding and addressing common issues can prevent downtime:

• Cavitation: Caused by vapor bubbles due to low inlet pressure; ensure proper suction conditions.


• Leakage: Worn seals or improper assembly can lead to leaks; replace seals and verify assembly procedures.


• Noise and Vibration: Misalignment or air in the system can cause noise; check alignment and bleed air from the system.

Comparing with Other Pump Types

When compared to other pump types, such as external gear pumps or vane pumps, IPS internal gear pumps offer unique advantages:

• Smoother Flow: Less pulsation compared to external gear pumps.


• Better Suction Capabilities: Can handle low NPSH conditions effectively.


• Versatility with Viscosity: Performs well across a wide range of fluid viscosities.

The KHG Series Internal Gear Pump demonstrates these advantages, making it a preferred choice in many applications.
