S Series Twin Screw Pumps

Blackmer® S Series Twin Screw Pumps are self-priming, double-ended positive displacement pumps that offer outstanding performance in the most demanding applications regardless of temperature, viscosity or pressure. This durable screw pump line is perfectly suited to applications in the chemical process, general industrial, transport and commercial marine markets.

S Series pumps are available in a wide range of configurations, including horizontal, vertical, high temperature, high pressure and high viscosity. These pumps provide flow rates ranging from 0.5 to 2,500 L/min (2.2 to 11,007 gpm) at differential pressures up to 60 bar (870 psi). S Series twin screw pumps can handle viscosities from 0.5 to 200,000 mm2/s (cSt) and temperatures up to 350°C (662°F).

Features and Benefits

S Series Twin Screw Pumps With Timing Gear (WTG)

Double-suction, self-priming twin screw pumps with external bearings and timing gear transmission. They are especially suitable for the delivery of fluids free of solids and/or with little abrasiveness.

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


  • Petroleum
  • Marine
  • Petrochemical
  • Liquid terminals
  • Refineries
  • Food & beverage
  • Chemical
  • Lubricating oil
  • Storage & transportation

S Series Twin Screw Pumps With Non-Timing Gear (NTG)

Single-suction design with a balance piston that compensates for axial pressure on the hydraulic components. Metal contact exists between the screw profiles and casing bore. These pumps are sutiable for the transfer of lubricating fluids with higher viscosities, such as bitumen and residual oil, at medium or high temperatures.

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


  • Asphalt
  • Chemicals
  • Heavy fuel oil
  • Liquid terminals
  • Petrochemical
  • Lubricating oil
  • Marine

S Series Multi-Phase Twin Screw Pumps

Designed for medium- to low-pressure applications, multi-phase twin screw pumps are robust, reliable and built to last within the commercial marine and oil & gas markets. These pumps are commonly used in the oilfields that have untreated streams, and have been designed for higher differential pressure and higher suction pressure applications.

  • Reduces backpressure
  • Increased production
  • Quick installation
  • Reduces downtime
  • Unique materials for extreme operating conditions
