LobePro rotary pumps are positive displacement pumps. A positive displacement pump operates by trapping a fixed amount of fluid from an intake pipe and then forcing (displacing) that trapped volume into a discharge pipe.
LobePro pumps utilize intermeshing 4-wing helical lobes mounted on parallel shafts. The shafts are rotated by gears with a maintenance friendly design (no complicated timing gears to worry about).
Here are several great reasons to choose a LobePro rotary lobe pump:
- Low shear/Pulse free operation
- Excellent for oil/water separation or highly viscous fluids
- Ability to pump at constant pressure at different flow rates
- Self-priming to 25′ wet
- Capacities from 0-2,656 GPM with pressures to 175 psi
- Forward and reverse pumping operation
- Easy access to wet-end for in-place wear part replacement
- Long operational lifespan at proper speed
- Low maintenance
- Space-saving compact design
- 10 to 1 turndown capability and reverse capability
- Run dry ability for a period of time
- Pump speed can be varied from 50 to 600 RPM
- Excellent for fine abrasives such as sand, sludge and bentonite because the pump can be run at low speed and lobes do not touch
