The Roper company objective in matching your process to the ideal gear pump solution is to maximize your uptime and minimize your cost of equipment ownership and utilization.
Gear Pump Types and Industrial Applications
The pump type, design model, and particular functional characteristics together determine the variety of gear pump industry applications for which the equipment may provide the right solution. For example, gear pumps often offer the best alternative for many purposes in agriculture, water management, energy production, oil refining, HVAC, and the food handling/processing industry, among others.
Generally speaking, gear pumps work by capturing and forcing fluid into a discharge pipe. The pumps are used for a vast array of fluid types, including high-viscosity liquids. Features like flow capacity, power, efficiency, Net Positive Suction Head (NPSH), Total Differential Head (THD), and others are among the key functional measures of the applicability of a given positive displacement pump model for a particular industrial application.
Roper manufactures positive displacement pumps, including diaphragm pumps, sliding vane pumps, and others. The Roper Pump 3600 Series is famous for its exceptional reliability and efficiency in bidirectional operation.
Advantages of Using Gear Pumps
Gear pumps are known for their efficiency in transferring fluid. They are designed to produce a steady flow of viscous fluids, minimize waste, and maximize productivity. Gear pumps generally only have two gears, which makes them easy to maintain and use. They also can manage a wide range of viscosities, for example, from very thin solvents to very thick oils. This is what makes them so useful in so many processes in so many different industries.
Other advantages of gear pumps include:
- Performance reliability
- Adaptability to so many different fluids and processes
- Compact designs: small pump sizes handle large fluid loads
- Energy efficient: high metering rates for low energy use
- Outstanding reliability: long-term durability
- Precision torque conveyance and operating speed
- Excellent self-priming: they prime fluids from very low levels
- Versatile engineering and manufacturing of a range of pump types
- High ratio of input to output force (That’s the ratio of total teeth on the input gear to those on the output gear.)
What Does Good Gear Performance Depend On?
A gear pump’s job is to displace fluid by a couple of rotating gears that move the liquid. To function, the machine generates pressure on and flow of the fluid. These are the necessary functional components of a gear pump for optimum performance quality:
| Construction Quality | The reliability of the gear pump requires durable materials and high-quality construction to perform ideally under intense pressure levels in punishing environments. |
| Viscosity Range | Gear pumps handle a wide range of high and low-viscosity fluids, which makes them valuable for industrial applications ranging from pumping thin solvents to thick oils, paint, adhesives, and even semi-solid materials like asphalt. |
| Temperature Range | Quality gear pumps tolerate temperature extremes and are adaptable to a wide range of fluctuations. |
| Flow Consistency | Despite pressure fluctuations, precise metering of the gear pump flow rate in industrial operations depends on the pump’s positive displacement functionality. |
| Ease of Maintenance | Gear pumps with simple designs involving the fewest moving parts possible typically require the least maintenance. |
Roper 3600 Series Gear Pumps
Gear pumps in the Roper 3600 Series are preferred for their smooth handling of densely viscous fluids and their equal efficiency in both directions of rotation. These superior industrial gear pumps are proven high performers in rough conditions, reliable to meet production demands and help minimize downtime. Some other reasons Roper has become the go-to supplier for today’s industrial-grade gear pumps include:

Roper 3600 Series Rebuild Kits
Full Roper rebuilding kits are available for the manufacturer’s line of standard gear pumps. For more details on those or for information on rebuilding custom Roper gear pumps, contact C&B Equipment as your local Roper 3600 series distributor, or contact Roper directly for answers to all your questions.
KEEP IN MIND: Maximum pumping speed and liquid flow can only be reached when the condition of the liquid material (viscosity) and the inlet pressure (suction) are appropriate for the pump.
Roper 3600 Series Gear Pump Sizes
A vast range of Roper gear pump applications is made possible by the many size selections in the 3600 series, to accommodate virtually any need for this class of industrial gear pump:
| Size 11
Size 17 Size 22 |
Size 32
Size 35 Size 43 |
Size 48
Size 58 |
Disadvantages of Using Gear Pumps
Like anything else, along with the many major advantages of gear pumps, they do present certain disadvantages, such as:
- Limited range of operation
- Small pump may not be good for high flow
- Not designed to run dry
- Issues with abrasives
- Maintenance costs in some cases
- Issues with low-viscosity fluids
The most common reason for problems with gear pumps is tooth overloading. That can cause stress levels to exceed the material’s tolerance limit.
