If operating at high temperatures, a suitable cooling system will be installed.
Pump vibration is within the API610 permitted range. 6 Bearing housingįull circular bracket design minimizes any vibration of the bearing housing. Using a balance line, seal chamber pressure on both sides (coupling and anti-coupling side) is designed to maintain suction pressure for the mechanical seal. Gland packing can be installed upon request. 5 Shaft seal and seal chamberĪll seals and plans for mechanical seals comply with API682 and API610 requirements. The double keyway design of the main shaft makes balancing easier. Minimizing main shaft deflection as far as possible prolongs bearing and seal life. 3 Wear ringsįitted with replaceable wear rings. The impeller is dynamically balanced to comply with API610 requirements. The impeller is firmly secured to the shaft by interference fit and split rings. The arrangement of impeller vanes and diffusers is designed to avoid vane-pulsation buildup. 2 Impellerĭesigned for high efficiency and low NPSH, the enclosed single-suction (BTBFD: double suction at 1st stage) multi-stage impeller is designed to meet a wide range of specific operating conditions. The centerline support design prevents misalignment caused by thermal expansion. The radially split outer casing is fitted metal-to-metal with a controlled compression gasket that ensures perfect sealing without misalignment.

The casing is designed in full compliance with API610 requirements (design pressure, nozzle external force, moment, etc.).Ĭylindrical forging from high-grade steel grants the strength required for safe operations under high pressure up to maximum operating temperature. This model adopts a fully enclosed impeller designed for specific operating conditions with maximum efficiency and low NPSH. 8 Replaceable wear ringsīoth the casing and impeller are fitted with wear rings. Shaft rigidity complies with API682 and API610 requirements, minimizing shaft deflection and extending mechanical seal life. 6 Lubricationīearings are lubricated using an oil flinger system. The bearing housing is equipped with a constant level oiler. Labyrinth end seals and deflectors (non-sparking materials) effectively retain oil in the housing and prevent entry of foreign material into the housing. 4 Replaceable labyrinth end seals and deflectors 3 Bearingsīearings are designed for a bearing life of at least 25,000 operating hours. The seal chamber is designed to comply with API682 and API610 standard dimensions.
The top centerline discharge design enables reliable self-venting. Metal-to-metal fitting prevents misalignment, ensuring perfect sealing. The casing is designed in compliance with API610.
