Depending on the structural material, knoll screw pumps are limited to 180° C with standard seals. Using a magnetic seal, the maximum allowable fluid temperature is increased to 300° C.
knoll screw pump advantages:
• The compact nature of the screw means higher volumetric efficiency compared to other displacement pump designs
• Robust design and balanced features enable very high pressures
• These pumps are inherently smooth and quiet
• The simplicity of the design makes the pump relatively cheap to produce compared to other rotary positive displacement pumps. They are also much less affected by physical scale than gear pumps and are typically used for large oil flows, for example over long distances
• Viscous fluids that cannot be handled by a centrifugal pump can be moved easily through a screw pump
• Because the pumping action is very limited, the output is very controllable. Doubling the size or speed theoretically just doubles the output
• Unlike centrifugal pumps, the output of screw pumps is completely independent of the discharge pressure
Running without centrifugal force means that pump speeds can be lower, making it controllable, smooth and less destructive
• This action makes the screw pump self-priming
• The discharge pressure of the gear pump can be very high due to physical limitations such as motor power, housing strength, shaft seal, and hydraulic factors such as volumetric efficiency
• The optimum efficiency point (BEP) of the centrifugal pump is very important. This does not apply to screw pumps
• Screw pumps have a low NPSHr compared to centrifugal pumps and are therefore very useful when the available net positive suction head (NPSHa) is small
• The screw pump is double rotating
• In contrast to other rotary positive displacement pumps, they have no timing gear and are of "all-metal" construction with only one shaft to seal
