MAINTENANCE REQUEST FORMS: PUMP REPAIR REQUEST FORM | PICKUP REQUEST FORM
The MAAG S Series Triple Screw pump is specifically designed for handling clear, lubricating liquids without solid content. They are designed to tackle the toughest application challenges in the oil and gas, process, and marine industries. The pumps provide a smooth, constant flow regardless of the operating pressure, temperature, and viscosity.
Like their twin screw counterpart, MAAG S triple screw pumps are self-priming, compact, robust, and can be ATEX-certified for use in explosive areas.




MAAG’s S Series Triple-Screw Pumps consist of three rotating parts, a male drive spindle (driver screw) and two female secondary spindles (driven screws). As the driver screw starts rotating, the driven screws also rotate. Due to the movement of these screws, a minimal vacuum starts producing at the inlet section. This vacuum causes the fluid to enter through the inlet valve. The fluid is trapped between the gap of the “screws” and rotated as the screws rotate. As pressure increases, the fluid is discharged from the outlet valve and transferred to the desired location.
