Rotary Pumps
Find the industrial rotary pump that meets your needs
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.
Try: 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.
Try: 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.
Try: 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.
- 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.
