Lobe Pumps





LobePro Rotary Pumps currently manufactures 13 models of positive displacement rotary lobe pumps divided into three series: S-Series (sludge/slurry and general use) pumps, C-Series (chemical/and corrosive resistant) pumps, and D-Series (duplex pumps and abrasive applications). Each series is also available in an API-Series (API-676 Compliant for Oil and Gas Industry). Reference pump and pump assembly drawings are available upon request.

Applications for LobePro pumps include: SludgeSlurries and MudOil and GasOil Spill and RecoveryBioSolids and BioFuelWater and WastewaterGeneral Industry,  Sugar and Food ProcessingConstruction Dewatering and  Environment RemediationMiningAgricultureWinePower Plants, and Chlorides, Hydroxides and H2S.


Rotary lobe pumps are used extensively in a variety of industries in place of progressive cavity pumps and centrifugal pumps. Rotary lobe pumps have an advantage over progressive cavity pumps because of their small size, low cost maintenance-in-place capability and ability to run dry. They also have advantages over centrifugal pumps because of their ability to handle small diameter solids and abrasives, and ability to pump a measured flow at a constant pressure at any pump rpm with low shear with little or no pulsation. In addition, rotary lobe pumps are more energy efficient than centrifugal pumps. This is important since studies show that energy costs are typically 80-87% of total lifetime pump costs.
