Our Industrial Rotary Lobe Pump is considered a viable alternative to Peristaltic and Progressing Cavity Pumps due to their in-line design, which enables easy and simple integration into pipework systems.
These Lobe Pumps offer a reversible design, which means they are ideal for tank emptying and refilling applications, removing the requirement for line stripping or a secondary pump for many users. The pumps also feature a relatively small pump head. The versatility of drive configurations allows the Industrial Lobe Pump to be easily integrated into mobile systems such as tankers and tractors. You can find more information about the drive configurations in the relevant tab.
How does a Rotary Lobe Pump work?
2 synchronised lobes revolve within the pump housing. The lobes do not come into contact with one another, this is prevented by timing gears located within the gearbox. As the lobes rotate, they create an expanding cavity at the pump suction which draws the fluid into the pump. The fluid is trapped by the lobes in pockets as they rotate which is then conveyed around the outside of the lobes, passing any solids with it along the way, and discharging out of the pump casing.
The pump shaft support is facilitated by bearings located outside of the fluid in the gearbox, limiting the discharge pressure to 5 bar.
Capacity is directly related to the speed at which the pump is operated and the flow is reversible by simply changing the direction of rotation of the drive.
Design:
These Industrial Rotary Lobe Pumps are classified as Rotary Positive Displacement Pumps, this means the capacity remains independent from system pressure which means that they can deliver the same flow rate across their rated pressure. This ensures that the pumps are suited to mobile applications where discharge conditions are constantly changing or for fixed-in-place applications where process fluid viscosities and densities vary.
Pump bodies are constructed from GG 30 continuously cast spheroidal graphite Iron with wear plates in wear-resistant steel & triple seal design as standard.
Lobes can be supplied in several different elastomer coatings including NBR, SBR, XNBR, EPDM and FPM. Lobe replacement is facilitated by a front pull-out design.
Different drive options are available to suit a wide variety of site-specific requirements such as ATEX-rated motor, hydraulic drives for truck mounting and diesel/petrol drives for portable systems.
Particular care has been taken in the design of these units to improve pump life and limit maintenance intervals in arduous and challenging applications. Each pump model has been through stringent and severe laboratory testing and field tests before being launched. Each pump is then individually tested before delivery.
