Brief introduction

Single-stage screw pump and self-priming screw pump are a new type of pump that operates according to the reciprocating meshing volume principle. The main working components are the eccentric screw (rotor) and the fixed sleeve (stator).

Single-Stage Screw Pump, Self-Priming Screw Pump is a single-screw transport pump, with its main working components being the eccentric helical screw (referred to as the rotor) and the inner surface of the screw sleeve, which is double-threaded helical (referred to as the stator). The working principle of the single-stage screw pump parameters is that when the motor drives the pump shaft to rotate, the screw rotates around its own axis while also rolling along the inner surface of the sleeve. This forms the pump's sealed chamber. With each rotation of the screw, the liquid within the sealed chamber is pushed forward by one pitch. As the screw rotates continuously, the liquid is propelled in a spiral manner from one sealed chamber to another, eventually extruded out of the pump body. The single-stage screw pump parameters are a new type of mechanical liquid conveying equipment, featuring simple structure, reliable operation, easy maintenance, continuous and uniform discharge, and stable pressure. The single-stage screw pump parameters are a pump that uses the rotation of the screw to suck and discharge liquids, and it is particularly suitable for handling thick liquids.

Single-stage screw pump, features of self-priming screw pump:
Single-stage screw pumps, due to their structure and working characteristics, offer numerous advantages compared to piston pumps, centrifugal pumps, vane pumps, and gear pumps:

1. Capable of conveying media with high solid content.
2. Uniform flow with stable pressure, more pronounced at low RPMs.
3. The flow is directly proportional to the pump's speed, thus offering excellent variable regulation capabilities.
4. Multi-functional pump capable of transporting media with varying viscosities.
5. The pump's installation position can be arbitrarily inclined.
6. Ideal for transporting sensitive items and goods prone to damage from centrifugal forces.
7. Compact, lightweight, low noise, simple structure, and easy to maintain.
