Open Top Type Single Screw Pumps

The NC type Open Top Type Single Screw Pumps, is a progressive cavity pump. Its main components are the rotor and the stator. The rotor is a screw with a large lead, high teeth, and a small helix inner diameter, and it has a specific cross - sectional shape. The stator is a matching screw sleeve. The two form a liquid - storage space. When the rotor rotates, the medium is transported axially from the suction end to the discharge end.

Product Features

● Compared with centrifugal pumps: The single-stage screw pump does not require the installation of inlet and pressure - end valves, and its flow rate is in a stable linear flow.

● Compared with piston pumps: The TPNC - type pump has self - priming ability, and its suction lift can reach up to 8.5 meters of water column.

● Compared with diaphragm pumps: The Spiral pump can transport various mixed impurities, media containing gases, solid particles or fibers, and can also transport various corrosive media.

● Compared with gear pumps: The TPNC - type pump can transport high - viscosity media.

● Compared with piston pumps, diaphragm pumps, and gear pumps: The NC - type pump can be used for pharmaceutical filling and metering

Application Fields
