Ingersoll Rand | Gear Pumps for Controlled Flow and Chemical Handling

Ingersoll Rand manufactures gear pump systems used in applications where flow must be controlled rather than simply transferred. Their magnetically coupled gear pumps use an external gear mechanism with a magnetic drive, eliminating shaft seals and isolating the fluid from the motor. This design removes a common failure point and allows operation with aggressive or hazardous fluids.

The pumps produce a steady, non-pulsating flow that is directly proportional to speed, making them suitable for dosing and metering systems where output must remain consistent under changing system pressure. Typical applications include chemical dosing, water treatment, and process systems that handle corrosive fluids or require precision flow control.

Ingersoll Rand manufactures positive-displacement gear pumps for applications requiring flow control, chemical compatibility, and repeatable performance. These pumps are typically used in dosing, transfer, and circulation systems that handle process fluids, additives, and chemicals.

Industrial Gear & Magnetic Drive Pump Solutions

The product lines most relevant to industrial fluid handling include magnetically coupled gear pumps and internal gear pumps. Both designs are used where steady, predictable flow is required under varying system conditions.

Industrial Process Gear Pumps

Ingersoll Rand industrial gear pumps use an internal gear design to move fluid. Fluid is conveyed between the gear teeth and casing, resulting in a steady discharge with minimal pulsation.

This type of pump is typically used for higher-viscosity fluids that require consistent transfer. Applications include:

Lubrication systems
Adhesives and sealants
Resins and coatings
General process fluid transfer

Internal gear pumps are selected for their ability to handle viscous fluids while maintaining a stable flow rate. Because flow is proportional to speed, they are used in systems where output needs to remain predictable.

The design uses relatively few moving components, which supports continuous-duty operation and simplifies maintenance compared to more complex pump types.

Magnetically Coupled Gear Pumps

Ingersoll Rand magnetically coupled gear pumps use an external gear design driven through a magnetic coupling. Torque is transmitted from the motor to the gear set through a containment shell, eliminating the need for a shaft seal.

There is no dynamic seal between the motor and the fluid. This design is used where leakage cannot be tolerated or where maintenance access is limited. Removing the seal eliminates a common failure point and avoids the need for seal support systems.

The pump produces a continuous, non-pulsating flow. Output is directly related to speed, which allows controlled dosing and repeatable delivery even when system pressure changes.

Typical operating characteristics include:

Flow rates up to approximately 650 GPH, depending on model
Differential pressure up to approximately 250 psi
Wide viscosity capability, from low-viscosity solvents to higher-viscosity fluids

Materials such as 316 stainless steel, Hastelloy, and titanium are used for chemical compatibility in corrosive environments. These pumps are commonly used in chemical dosing, water treatment, and systems handling corrosive or hazardous fluids.

Applications Across Industrial Systems

Ingersoll Rand gear pumps are used in systems where fluid properties and process requirements make flow control critical. Typical industries include chemical processing, water and wastewater treatment, coatings and resins, energy systems, and OEM equipment.

These pumps are applied where the system requires:

Controlled dosing or metering
Handling of corrosive or hazardous fluids
Transfer of viscous materials
Stable flow under changing system pressure

Magnetic drive designs are used where containment is required. Internal gear pumps are used where viscosity and continuous transfer are the primary factors.

Engineering Considerations for Gear Pump Selection

Gear pump selection is driven by fluid properties and operating conditions. Viscosity, temperature, pressure, and chemical compatibility all affect performance and component life. Magnetically coupled gear pumps are used where seal leakage is unacceptable or maintenance needs to be minimized. Internal gear pumps are used where fluid viscosity is higher and continuous operation is required.

Operating limits must be respected. Excessive pressure, incorrect material selection, or operating outside the intended viscosity range will reduce pump life. System design should account for these factors to ensure the pump operates within its intended range.

Applying Ingersoll Rand Gear Pumps

Ingersoll Rand gear pumps are typically used in systems where flow control and fluid-handling requirements are clearly defined. Proper selection depends on matching the pump type to the fluid and the process.

This includes evaluating viscosity, required flow rate, pressure conditions, and material compatibility. Integration into the system should account for suction conditions, speed control, and operating limits to maintain consistent performance over time.
