Rotary Lobe Pumps are type of positive displacement pump that use two lobes or more as the impeller to move the liquids. There are some lobe design for example Bi-lobe and dual wing rotary piston. These two lobe are connected to the shaft in the pump casing. One shaft called as driving shaft whereas the other shaft as driven. The flexible coupling connect the electric motor shaft and driving shaft hence driving shaft rotate. The set of gearbox (timing gear) transmit the rotation to driven shaft hence both of the shaft rotate. This technology is the reason of no metal to metal contact between the lobes. 

PRODUCT INFORMATION

There is a wide range of products at Rotary Lobe Pump, OMAC.

WORKING PRINCIPLE

In this paragraph we are going to explain the working principal of rotary lobe pump. It has similarity to the internal gear pump. The lobes of the rotary lobe pump is an integrated part to the shaft. One shaft (Driver Shaft) connected to the electric motor shaft through a coupling device. Another shaft is driven shaft . Once the electric motor rotate it will transmit the rotation to the Driving shaft and there is a gearbox connecting the driver shaft to the driven shaft hence both of lobe rotate and move the liquids to the discharge side. 

As the pump rotates in relative high speed, it creates lower pressure zone  at the pump inlet and draws the liquids in to the pump and the rotation of the lobes move it to the discharge side. 

APPLICATIONS

Rotary Lobe Pump

Rotary Lobe Pump Series B

The B series lobe pumps satisfy most transfer applications to suit hygienic and chemical characteristics. OMAC’S lobe pumps are appreciated all over the world for stoutness and performances, assures good services, long endurance, easy and cheap maintenance.

 

This range consists of 16 models with deliveries from 0.05 to 200 m³/hr with the following versions available: ST Model with standard tolerances, SM Model with increased tolerances, both being made in AISI 316 stainless steel and both available with Duplex shafts.

Series BE

The BE series pumps are simple and robust and are characterised by their monoblock design. The drive unit, thanks to the hallow shaft and to the rear cover provided with an IEC flange, is directly fixed to the pump by creating a unique compact and light body.

 

The new design, with smooth cover and fixing nut built in the rotors, improves the cleaning standard. This series have only bi-lobe rotary piston rotors in S.S. 316 L or in antifriction alloy CY5SnBiM, which ensure an excellent volumetric efficiency and a smooth and regular transfer of several liquid or viscous products.
