Twin Screw Pumps

With Timing Gear (WTG)

Maag S Series (WTG) Twin Screw Pumps are double-suction, self-priming twin screw pumps with external bearings and a timing gear transmission.

The axial pressure on the S Series (WTG) Twin Screw Pumps’ hydraulic components is balanced automatically with no metal contact between the hydraulic parts.

The pumps are ideal for transferring non-lubricating or moderately abrasive fluids. Six different models in 80 different sizes are available to accommodate a wide range of temperatures, viscosities and operating conditions.

No Timing Gear (NTG)

Maag S Series Twin Screw Pumps 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.

Multi-Phase Twin Screw Pumps

Maag MS Multi-phase Twin Screw Pumps are designed for medium- to low-pressure applications, and are commonly used with untreated streams in the field, such as oil, gas and water.

Multi-phase Twin Screw Pumps utilize a screw profile and design, along with a special pump casing chamber, to effectively handle the small particulates.

Triple Screw Pumps

Maag S Series Triple Screw Pumps are positive displacement rotatory pumps which adopt a cycloid profile of meshing principals at the screw profile. The power spindle is driven by a motor and the idler spindles are driven by fluid hydraulic power in an intermeshing screw groove. Hydraulic force on the spindle is balanced by the hydraulic load on the balanced piston.

These pumps are ideal for handling smooth constant flow across a wide range of viscosities, temperatures and pressures without solid content. Three models are available.
