MLB※W Pressure Displacing Motor Pump

  • Volumetric type gear pump featuring a pressure displacement mechanism
  • Highly efficient and durable.  Various types / specifications available
  • Utilized in various volumetric type lubrication units

 

The “LW” pumps, MLA※W and MLB※W models, designed for centralized lubrication system units utilizing  the  volumetric  type  system,  are  small  gear  pumps  featuring  a  pressure  displacement mechanism.

The body and casing of the MLB※W model have been produced from die-cast aluminum and the functioning components have been designed to consume less space, allowing a significant reduction in product weight.
