Inner Structure
1. The external bearing system allows for individual lubrication, making it capable of handling both lubricating and non-lubricating media.
2. The timing gears ensure no direct metal contact between rotating parts, ensuring a long service life and safe operation even during short dry runs.
3. A circular valve is integrated to regulate pressure by redirecting excess medium back to the pump’s inlet or reservoir when necessary, helping to reduce torque and maintain stable operation.
4. During operation, the driving and driven screws form a sealed chamber with the pump casing, allowing the medium to be continuously and smoothly transferred from the suction side to the discharge side as the shafts rotate. This ensures a consistent, pulse-free flow due to the constant volume of the sealed chamber.
