Blackmer Sliding Vane Pumps

Blackmer Sliding Vane Pumps – S Series Screw Pumps are self-priming double ended positive displacement pumps available with or without external timing gears and bearings. Twin Screw Pump and Triple Screw Pump designs provide complete axial balancing of the rotating screws and with timing gear technologies, eliminate metal-to-metal contact within the pump. Blackmer’s carefully crafted screw technology rotates within a cylindrical cavity, transferring fluid and materials along the screw’s spindle.

Blackmer S Series Screw Pumps – Twin with Non-Timing Gear (NTG)

S Series Twin Screw Pumps (NTG) with non-timing gear transmission feature a single-suction design. The axial pressure on the hydraulic components is compensated by a balance piston. Metal contact exists between the screw profiles and casing bore. The S Series (NTG) Twin Screw Pumps transfer lubricating fluids with higher viscosities, such as bitumen and residual oil, at medium or high temperatures.

Features and Benefits:

  • Low noise
  • No emulsified shear
  • Low pulsation
  • Suitable for wide range of viscosities
  • Low fluid agitation
  • Direct drive

Common Applications & Industries Served

  • Asphalt
  • Chemicals
  • Heavy Fuel Oil
  • Liquid Terminals
  • Petrochemical
  • Lubricating Oil
  • Marine

Blackmer S Series Screw Pumps – Triple

S Series Triple Screw Pumps are positive displacement rotatory pumps for handling clear, lubricating liquids without solid content in the most demanding applications. Providing smooth constant flow across a wide range of viscosities, temperatures and pressures, these extremely efficient pumps are reliable, compact, self-priming, low noise and environmentally friendly.

Features and Benefits:

  • Low noise
  • Low maintenance
  • Reliable
  • Self-priming
  • Environmentally friendly

Common Applications & Industries Served

  • Lube oil delivery
  • Hydraulic units
  • Machining
  • Marine
