- Screw pumps lift water one level up; channels bring water one level down.--> A screw pump will take water from the square next to it (you can define the source direction), 1-Z level down. So if you have water at level Z=0 and a pump at level Z1, when active the pump will lift it to it's level, (1 up) and deliver it in front of it.To prime a water pump, start by turning off electrical power to the pump and opening any relief valves on the system. Then, insert a hose into the plumbing fixture and turn it on so the tank in the pump starts filling up.

The screw pump is a positive displacement pump. This indicates that the liquid is moved by consistently displacing the space occupied by the liquid. The screw pump is driven . See more
Centrifugal pumps play a crucial role in various industries, ensuring the efficient transfer of fluids from one location to another. One important component of centrifugal pumps is the balance line, which helps maintain the hydraulic balance within the pump. The balance line is a key feature in pumps such as the BB3 and BB5, where its location and size are carefully designed to optimize pump performance.
Centrifugal pump balance lines are used on pumps with 2 or more stages - their primary purpose being an integral part of the pump's axial thrust compensation. Note that not all pumps utilize a balance line - it depends on how the design is set up to handle axial thrust. While not meant to be an exhaustive list,
Hydraulic Balance Line Pump
In a centrifugal pump, the hydraulic balance line is essential for ensuring that the pressure on both sides of the impeller remains balanced. This is particularly important in high-pressure applications where any imbalance could lead to pump failure or reduced efficiency. The hydraulic balance line is typically located near the impeller or on the casing of the pump, allowing for the equalization of pressure and minimizing the risk of cavitation.
Pump Balance Line Size
The size of the balance line in a centrifugal pump is critical for maintaining the hydraulic balance and preventing issues such as vibration or excessive wear on pump components. The size of the balance line is determined based on factors such as the flow rate, pressure, and type of fluid being pumped. A balance line that is too small may result in pressure imbalances, while a line that is too large could lead to inefficiencies in the pump system.
Axial Pump Balance Line
In axial pumps, the balance line plays a crucial role in ensuring that the axial thrust generated by the impeller is properly balanced. The balance line in an axial pump is designed to counteract the axial forces exerted on the impeller, preventing damage to the pump bearings and shaft. Proper sizing and placement of the balance line are essential for maintaining the long-term reliability and efficiency of axial pumps.

I've posted examples of a BB3 and a BB5 pump below with the location of the balance line highlighted for each. (The configuration for a BB4 will typically be the same as a BB5). As
Advantages of the screw pump. The screw pump combines many advantageous features of other pump solutions: Like the centrifugal pump, for example, it has no pressure or suction valves, and like a piston pump, the eccentric screw pump also has excellent pumping speed.The flow rate is constant and speed-dependent.Like a gear or screw pump, it handles pumped material with .
