STP

Marine engineers and operators rely on reliable cargo transfer equipment to ensure efficient and safe operation. Framo's STP is a marine-rated cargo pump designed for handling oil and chemicals. This submerged turbine cargo pump utilizes a hydraulic drive system and is installed within the cargo tank. The STP is designed for demanding marine applications and its performance is detailed in the manufacturer's data sheet. Common issues encountered with the STP include cargo/hydraulic seal leakage through the cofferdam, hydraulic motor wear due to poor oil cleanliness, impeller cavitation damage, and bearing wear in the pump stack. To maintain optimal performance, it's crucial to keep a supply of mechanical seal kits, bearings, wear rings, O-rings, and hydraulic motor seal kits on hand. Service procedures include regular cofferdam purging and monitoring before and after cargo discharge. Hydraulic oil sampling and filter maintenance should be carried out according to the planned maintenance schedule. Lift-out inspections are typically performed during drydock periods.
