What is a screw pump:
Screw pump is a kind of positive displacement pump, composed of rotor and stator. The metal rotor drives the stator through a chain and begins filling the cavity with an equal amount of liquid, which is then pushed through the pump outlet. They are highly rugged pumping systems that ensure optimal performance and reliability.
How the screw pump works:
The rotor in the pump rotates in the stator, and as it rotates, the cavity in the stator is filled with process media and is brought to the pump outlet under pressure. The fluid bag has a set volume that determines the volume flow of the pump, which is proportional to the speed of the rotor and results in a low level of shear and almost no pulse.
Advantages of KNOLL screw pump:
• Has a uniform flow proportional to the rotational speed
• Suitable for low NPSHa and suction (up to 8 m) applications, depending on size, stage and speed
• Capable of handling shear-sensitive and heterogeneous fluids containing gases, solids, abrasive particles and fibrous materials
• Can pump low and high viscosity fluids
• Can be used for low flow and metering applications
• Wide temperature range from -40ºC to +150ºC
• Low pulsation, minimal impact on process media
• High discharge pressure, up to 48 bar (6 bar/stage). Cells have 1-8 phases
• Reversible operation with effective pressure up to 12 bar
• Pumps can be manufactured to meet the requirements of a wide range of available materials, meaning that pumps can be tailored to meet the needs of individual applications
• Modular design based on the Diamond series, which means that accessories and design adjustments can be added to build custom units while ensuring that major spare parts remain up to standard.
• The patented pin joint design provides enhanced solid passage and protection as well as high reliability and up to 8,000 hours of operating life (before maintenance or failure).
