Single Screw Pump Oil And Gas Drilling, On Shore And Offshore Platform

APG Screw pumps are a type of rotary Positive Displacement Pumps. These pumps are the best choice for the transfer of liquids requiring smooth and non-pulsating flow. These pumps are known for their high suction ability. Single screw pumps cater to a number of industries including shipping, chemical, ceramic, paper, wastewater, paint, oil & gas, and many more. These pumps can efficiently handle the transfer of abrasive and non-abrasive liquids, with and without solid particles such as sewage, sludge, bilge, and foods such as jelly, yeast, and ketchup. These pumps offer very low life cycle costs. Also, single screw pumps are non-clogging.

Single Screw Pumps are reversible. These pumps work on the principle of positive displacement. These pumps comprise a single helix metallic rotor and a double helix elastomer stator. The liquid is pumped through the suction port. As the rotor moves inside the stator, cavities are formed. The liquid moves along the cavities due to positive displacement and gets discharged from the discharge port of the pump.

Please check below technical specifications for your reference.

Screw pumps mainly consisted of the discharge port, the stator, the rotor, the flexible section, the middle axis, suction room, seal, bearing, driveshaft, bearing body. Among these parts, the wearing parts are the rotor and stator. The screw pump wet parts can be made with high-quality rubber. According to different fluids' content and property, we'll provide a certain configuration on screw pumps. For example, for the abrasive material, we kindly suggest using special rubber instead of stainless steel. As we know, the S.S can't adapt abrasive material but corrosive material. Compared to other pumps, the screw pump is not easy to lead swirl. This helps much to maintain pump capacity. It is not sensitive to viscosity so it is capable to transfer material with high viscosity

Screw pump transfer drilling fluid via the screw conveyor rotation. The Center screw pole is the positive pole, the two sides screw conveyor is the negative pole. Negative poles rotate in the opposite direction with a positive pole.

Actually, when the screw axis is rotating, the lower Vroom will become large. Vroom will close against fluid sucked. The closed room will be pushed forward along the axle. Then the new suction cavity generates on the suction end. One and one closed cavity move forward, the fluid will be pressed out.

Positive Displacement
Because of single rotating elements, progressive cavities are generated which deliver a uniform, metered, and non-pulsating flow. The developed head is independent of the rotational speed, whereas the capacity is proportionate to the speed.

Self-priming
Inherently self-priming, the pumps can work on snore and do not require a foot valve.

Non-Clogging
Can handle solids in suspension or media containing a high percentage of solids.

Low NPSH Requirement
Suction lift capabilities of up to 9.5mWc and effective in high vacuum conditions.

Low Internal Velocity
Minimum degradation of shear-sensitive media, and can also handle highly viscous materials having pseudo-plastic characteristics.

Reversible
Due to the reversible rotation capabilities, Progressive Cavity Pumps can perform with equal efficiency in either direction.

Silent Running
Rotors turn inside a resilient stator and thus generate little noise.

Separate Bearing Housing
Fluids can be pumped without no contamination.
