Sanitary Lobe Pump Acculobe™ from Top-Line

The AccuLobe™ is a sanitary lobe pump designed to provide superior metering accuracy and repeatability, especially for viscous or shear sensitive fluids. Its multilobe design allows precise volumetric dosing for filling and packaging, lab and pilot plant, or manufacturing applications as well as general fluid transfer where flow rates (0.5-9.2 gpm /2-35 lpm) and medium pressures
(0-175 /0-12 bar ) are required.


  • Five-lobe, 20cc/rev. displacement rotors combine superior metering repeatability with reduced pulsation and quiet operation.
  • Rotor case geometry maintains volumetric efficiency, while chamfered cusps around the ports enable self-draining for enhanced CIP/SIP.
  • Front-loading seals provide ease of maintenance, with flush rotor retainers for enhanced CIP/SIP.
  • Unique one-piece rotor case provides superior concentricity, contributing to longer seal and bearing life, in a smaller footprint.
  • Non-contacting lobes may run dry with seal flush. Reversible direction of flow allows use of one pump for filling or draining.


  • Single mechanical seal, SiC faces, FDA EPDM elastomers. (Standard).
  • Foot mount. (Standard).
  • ¾” sanitary clamp connections (5/8” bore) with vertical ports. (Standard).


For Sealing:

  • Single mechanical seal, SiC, FDA Viton®
  • Single mechanical seal mounted for flush/quench, FDA EPDM or FDA Viton®
  • Single O-Ring Seals-FDA Viton®  

For Mounting:

  • Flange (bulkhead) mount.
  • Drop-in face-mount flange interchangeable with common pumps.
  • NEMA 143/145TC motor mount with integral 3:1 gear reduction.
  • IEC Frame 80 motor mount with integral 3:1 gear reduction.

For Porting:

  • ¾” sanitary clamp (5/8” bore), horizontal ports.
  • ½”sanitary clamp (3/8” bore), vertical or horizontal.
  • ¾” weld neck (5/8” bore), vertical or horizontal.
  • ½” weld neck (3/8” bore), vertical or horizontal.
