Recently, PSG's Blackmer said that its S-Series twin-screw pumps can optimize the reliability, flexibility, economy, performance and value of critical liquids from ship to tank, and the operational capacity will meet the needs of shipyards and shipping companies.
Blackmer's S-Series twin-screw pumps are suitable for tanker loading and unloading because of their compact design, consisting of two screws that mesh during operation to form a cavity that seals against the surrounding pump casing.
When the screw shaft is running, the delivered liquid moves axially, helping the liquid to stabilize and continuously transfer to the center of the pump at the discharge port. This method of operation will ensure efficient and near-pulse-free transport of liquids, which is a key consideration for long-distance transport of highly viscous liquids.
Blackmer's S-Series twin-screw pumps feature a timing gear (WTG) construction and a double-suction design with no metal contact between the hydraulic components and axial auto-balance. Since there is no liquid agitation or emulsification shear, it is low in noise and almost pulsating, suitable for conveying corrosive and non-corrosive, low viscosity or high viscosity and clean or abrasive liquids. Other features and benefits of the S-Series twin-screw pump include self-priming, convenient compact design, short-time dry running capability, high suction booster head and constant flow in varying conditions.
