Rotary pumps are used in various applications from the petroleum industry to the lumber industry. There are major kinds of rotary pumps for sale: gear pumps, screw pumps and rotary vane pumps. Gear pumps are perhaps the simplest rotary pump with enmeshed gears that turn away from each other. Gear pumps can have internal and external gears. Screw pumps consist of two screws that turn in the opposite direction—one clockwise and the other counter-clockwise. The rotary vane pump has the same kind of casing as other rotary pumps, and has a rotor inside that turns, trapping fluid between the casing and the rotors, which draws fluid through the pump.
This guide supplies information about rotary pump manufacturers as well as rotary pump suppliers and rotary pump distributors. You’ll find the information divided by the three main types of rotary pumps.
1. Pick gear rotary pumps for its reliability.
2. Use screw pumps for their capacity to pump fluid without churning.
3. Rely on rotary vane pumps for pumping low viscosity liquid.

Pick gear rotary pumps for their versatility
Because of their design, gear rotary pumps can pump fluids from fuel to chocolate. They can also handle fluids at 750 degrees F. The internal gear pumps work well for fluids of various viscosities. Externally geared pumps work well for hazardous or corrosive fluids.
I recommend: There is more than one rotary pump manufacturer that is also a rotary pump supplier as well as a rotary pump distributor. Two manufacturers of gear rotary pumps are Haight Pumps and Viking Pump. Both manufacturers of gear rotary pumps make internal gear pumps as well as external gear pumps.
Rely on the toughness and efficiency of screw rotary pumps
Screw pumps are the oldest of the designs for industrial rotary pumps. Their efficiency and toughness explain why the screw rotary pump is still in use today. The screw pump pumps without churning and can pump everything from lubrication for engines to sawdust in the lumber industry. The screw pump can be either horizontal or vertical.
I recommend: Two manufacturers of these industrial rotary pumps are Warren Pumps and Imo Pumps.
Use vane rotary pumps to pump low viscosity fluid effectively
These rotary pumps excel at pumping low viscosity fluid for long periods. Common uses of vane rotary pumps are for everything from propellants and aerosols to alcohol, Freon and more.
I recommend: Two manufactures of vane rotary pumps are Gardner Denver Thomas and ULVAC Technologies. These vane rotary pumps are maintenance-free and can be rather compact in size.
Tips & Tactics
Helpful advice for making the most of this Guide
- • When seeking a rotary pump for sale, consider a company that manufactures a shuttle block rotary piston pump that can replace or retro-fit even the oldest pumps with minor modifications. This could be a cost-saving measure, saving your company from buying a new rotary pump through suppliers of rotary pumps.

Rotary pumps have applications in various equipment, such as hydraulic systems, laboratory equipment and automotive mechanisms. Before searching for a rotary pump that fits your application requirements, you need to be conversant with certain technical terms. Pump manufacturers use various key terms to describe types of rotary pumps and to specify the properties of rotary pumps. This guide will give you an idea about certain popular rotary pump terms, such as rotary gear pumps, rotary vane pumps, rotary lobe pumps and viscosity.

Positive-displacement pumps
In a positive-displacement pump, a fixed amount of fluid is trapped inside the pump body and this trapped fluid is forced out through the discharge pipe. A rotary pump is the most common type of positive-displacement pump.
I recommend: Rensselaer Polytechnic Institute provides information about the positive-displacement pump and its different types. You can also read through the description of positive displacement pumps at International Vacuum, an online magazine.
Rotary gear pumps
As the name indicates, rotary gear pumps are comprised of gears to force the fluid. Rotary gear pumps are suitable for high-pressure and high-volume applications.
I recommend: Alfa Pumps & Systems, a gear pump manufacturer, provides the basics of gear pumps, including their construction, principle of operation and typical applications.
Internal gear pumps
These are positive-displacement pumps with an internal gear that is driven by the input shaft. The internal gear drives an external gear that rotates around its center. These gear pumps are suitable for pumping fluids that have low viscosity.
I recommend: To understand the construction and working of an internal gear pump, you can read through an informative article at Hydraulic Equipment Manufacturers.
External gear pumps
External gear pumps use two identical gears rotating against each other, out of which the pinion is driven by the prime mover and the other gear rotates with it. External gear pumps are useful for applications such as fuel systems and chemical industry equipment.
I recommend: Pump School provides information about external gear pumps.
Rotary vane pumps
Unlike rotary gear pumps, rotary vane pumps use vanes in the form of blades, buckets, rollers or slippers. These provide high-pressure applications.
I recommend: Cole-Parmer provides information about rotary vane pumps.
Rotary lobe pumps
These rotary pumps are comprised of rotor lobes and are suitable for low-shear applications.
I recommend: Hydraulic Institute provides a definition of rotary lobe pumps. You can also read through the basics of rotary lobe pumps at Viking Pump.
Viscosity
Viscosity of the fluid is an important parameter for the design and performance of a rotary pump. Viscosity indicates the resistance of the fluid to flow. The more viscous the liquid, the lower its flowing rate.
I recommend: To understand the meaning of viscosity and its units, read through information at STLE. Additionally, Eaton Corporation offers a hydraulics glossary that explains viscosity.
