ROTARY LOBE PUMPS

With our diverse standard and high performance pumps we are able to serve all your needs and response to any challenge. Our positive displacement rotary lobe pumps are robust, self-priming and have running dry capability. Our products porfolio offer rotary lob pumps for most applications. We offer explosion proof and seal-less pumps for the petrochemical industry, pumps with CIP option (cleaning in place), pumps with minimal surface roughness for the pharmaceutical and food industry and high pressure pumps for dynamic applications etc.

Our pumps are operational with nearly all liquids in the viscosity range between 1 and 1.400.000 mPa.s (higher viscosity on request). Rotary lobe pumps are suitable for middle to high viscosity liquids, liquids containing soft or abrasive particles as well as for dirty or polluted liquids.

We choose the pump materials carefully depending on specific requirements and objectives of your application.

Pressure: up to 64 bar
Viscosity: up to 1.400.000 mPas
Flow rates: up to 28.548 l/min (1.713 m³/h)
Suction lift: up to 8 m

ROTARY LOBE PUMPS: KE & KD BLUE Series

For high end applications, high process efficiency and quality

Our rotary lobe pumps are self-priming, dry-run capable and reversible pumps designed for highly viscous liquids containing solid particles. Two non-contacting rotary lobes work together to transfer the liquid, while the shafts are driven by timing gears outside the process liquid.

Because of the very large internal cavities, rotary lobe pumps are able to handle extremely viscous liquids and large abrasive particles.

On demand, we can provide rotary lobe pumps which API, ATEX, TR-CU 10, TR-CU 12 and TA Luft compliant.

Pressure: up to 40 bar
Viscosity: up to 3.400.000 mPas
Flow rates: 1 up to 5.000 l/min (0,06 to 300 m³/h)
RPM: up to 3000 rpm
Suction lift: up to 8 m
Particle size: max 80 mm

Temperature: -60 to 450°C

ROTARY LOBE PUMPS: KS & KDS BLUE Series

Hardened design for heavy duty applications

Our KS & KDS Blue Series are specialy designed for heavy duty applications and liquides with highly abrasive particles.

On demand, we can provide rotary lobe pumps which API, ATEX, TR-CU 10, TR-CU 12 and TA Luft compliant.

Pressure: up to 70 bar
Viscosity: up to 3.400.000 mPas
Flow rates: 2 up to 2.474 l/min (0,12 to 148 m³/h)
Particle size: max 50 mm
Suction lift: up to 4 m
Temperature: -60 to 450°C
Materials: all available materials

MULTI-WING LOBE PUMPS: KM BLUE Series

For high end applications, high prozess efficiency and quality

Our Multi-Win Lobe Pumps are a combination of gear and rotary lobe pumps designed for highly viscous liquids containing small solid particles. Two noncontacting lobes, consisting of multiple wings, work together to transfer the liquid, while the shafts are driven by timing gears outside the process liquid.

Because of the large number of lobes, multi-wing pumps are self-priming, dry-run capable and reversible pumps capable of handling extremely viscous liquids and small abrasive particles.

On demand, we can provide multi-wing lobe pumps which API, ATEX, TR-CU 10, TR-CU 12 and TA Luft compliant.

Pressure: up to 70 bar
Viscosity: up to 3.400.000 mPas
Flow rates: 2 to 3.875 l/min (0,15 to 233 m³/h)
RPM: up to 750 rpm
Particle size: max 50 mm
Efficiancy: 75 to 92%
Suction lift: up to 6 m
Temperature: -20 to 250°C
Materials: all available materials
Seals: lip seals, packing, single or double mechanical seals
