S Series are self-priming double-ended positive displacement pumps available with or without external timing gears and bearings. Twin and triple screw designs provide complete axial balancing of the rotating screws and their timing technologies eliminate metal-to-metal contact with the pump.
S Series pumps are Atex-certified for use in explosive or dangerous environments, and have been specifically designed to address the difficult pumping challenges found in the oil & gas, process and marine industries. S Series pumps provide solutions that can meet the toughest application challenges regardless of temperature, viscosity or pressure.
S Series pumps are offered in four distinct lines, each having multiple model configurations and sizes:
Twin Screw Pumps (WTG) are double-suction, self-priming twin screw pumps with external bearings and timing gear transmissions. They are especially suited for the delivery of fluids free of solid substances and/or with little abrasives.
Twin Screw Pumps with non-timing (NTG) gear transmission feature a single-suction design and are ideally suited for transferring lubricating fluids with higher viscosities, such as bitumen and residual oil, at medium or high temperatures.
Multi-Phase Twin Screw Pumps have been designed for medium- to low-pressure applications and are robust, reliable and built to last within the water and oil & gas industries. Multi-phase pumps are commonly used in the oilfields that have untreated streams and are ideal for higher differential pressure and higher suction pressure applications.
Triple Screw Pumps are specifically designed for handling clear, lubricating liquids without solid content in the most demanding applications. Providing a smooth constant flow across a wide range of viscosities, temperatures and pressures, these extremely efficient pumps are reliable, compact, self-priming, low noise emission and environmentally friendly.
