Compared to ordinary screw pumps, single-stage screw pumps have some special structural features. These features are primarily designed to meet the unique requirements of the dosing process. The following are some of the special structural features of single-stage screw pumps:

Material Selection:

The stator of a single-stage screw pump is typically made of a variety of elastic materials to accommodate the transport requirements of different media.

Key components such as the rotor and stator may be made of more corrosion-resistant materials to ensure stability and durability when transporting corrosive media.

Seal Structure:

The seal structure of a single-stage screw pump may be optimized to improve sealing performance and prevent media leakage.

Some models of single-stage screw pumps may use mechanical seals or packing seals to accommodate different operating pressures and media characteristics.

Adjustability:

Single-stage screw pumps generally have good variable adjustability. Their flow rate is proportional to the speed, and the flow rate can be adjusted by adjusting the speed.

Some specially designed Single-stage dosing screw pumps may also be equipped with a flow controller or pressure sensor for more precise flow and pressure control.

Compact Structure:

Single-stage dosing screw pumps are typically compact, making them easier to install and maintain.

Some models may feature an integrated design, integrating the motor and pump body to further save space.

Adaptable Design:

Single-stage dosing screw pumps may have special adaptable designs, such as those for conveying high-viscosity fluids or media containing hard particles or fibers.

Their structure may be optimized to minimize agitation and damage within the pump body, maintaining the integrity of the media.

Maintenance Ease:

Single-stage dosing screw pumps may have fewer parts and a relatively simple structure, making them easy to disassemble and repair.

Some models may utilize standardized parts, facilitating the procurement and replacement of spare parts.
