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.
