GTA Submersible Archimedes Screw Pumps

Submersible Archimedes screw pumps

The GTA Pump series are multi-purpose submersible Archimedes positive displacement high-performance screw pumps. In addition to being a primary oil transfer pump, the GTA pumps can be utilized for numerous applications such as offloading emergency pumping of heavy crude, bitumen, tank cleaning, pipeline maintenance, sludge removal, etc. These pumps also come in a stainless steel series, specially designed for long-term permanent use on Vessels.


“Reliability and longevity for pumping any kinds of high-viscous liquids"

How it works

GTA pumps are easy to deploy and versatile to use. For example, an oil skimmer fitted with a GTA pump can easily have its pump removed and used for other pumping duties.

The special internal geometry of the GTA pump design ensures a gentle pumping action that will not emulsify the liquid and ensures the efficient movement of the fluid through the unit.

The smooth operation and easy flow control also reduce cavitation for a constant flow.

Because the pumps never lose their prime, they are operational from the moment they hit the liquid.

The screw pump, although an ancient Egyptian invention from more than 2,000 years ago, continues to prove its worth in modern industries with its reliability, versatility, and efficiency. It pumps fluids of high viscosity and handles large pressure changes with little impact on performance.

Lamor’s GTA Pump series are multi-purpose, high-performance, hydraulically driven submersible positive displacement Archimedes screw pumps. The capacities of the GTA pumps are certified by Bureau Veritas in varying oil viscosities.

The high-torque hydraulic motors make the pumps extremely efficient. Pump models and capacities vary from 20 m³/h to 140 m³/h (88–616 gpm) and operate in temperatures ranging from –20 to +60°C (–4 to 140°F), reaching up to 14 bar outlet pressure.

The pump casing is compact and, depending on the model and intended application, made of robust yet lightweight aluminum or stainless steel. All internal components are made of acid-proof steel with specialized seals for reliable operation and longevity.
