Maag’s S Series Twin Screw Pumps (WTG) are double-suction, self-priming twin screw pumps with external bearings and timing gears transmission. They are especially suitable for the delivery of fluids free of solid substances and/or with little abrasiveness.

Maag S Series Twin Screw Pumps with non-timing (NTG) 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.

Multi-phase Pumps are commonly used in oil fields with untreated streams. In order to satisfy the demands of oil, gas and water containing small particulates, the Multi-phase Pumps adopt a unique screw profile and design, along with a special pump casing chamber, to achieve an increase in mixture and heat distribution. A variety of materials and seals are available to meet challenging operating conditions in the field.
