VL / VLS (Vertical In-Line Close or Split Coupled) Information

Features with Benefits

BRACKETS

• The heavy duty cast and machined motor bra provide the motor with a rigid and reliable mounting surface
• Accurately machined register fit of brackets allows for concentricity and near perfect alignment of rating parts

CASE WEAR RINGS

• Replaceable case wear rings protect the pump casing from wear and tear and permit simple and easy maintenance of proper running clearances.
• Case wear rings reduce maintenance costs and help maintain high operating efficiencies.

INLINE FLANGES

• Inline design allows for space savings, being mounted “in-the-line” requiring no floor space.
• Inline design reduces initial cost by saving in material and installation costs with bases and mounting foundations
• Flanges are sized with the same suction and discharge sizes according to flow rate to most engineered pipe sizing, thus eliminating the need for reducers, elbows, or other fittings

IMPELLERS

• Engineered “closed” (double shrouded) impellers with Francis Vane design improves the pump’s efficiency.
• Extended vanes and enlarged eye contribute to a reduction in vibration and noise as well as reduced overall NPSH required for these pumps.
• Impellers are statically and dynamically balanced to ISO 1940-G3, decreasing noise and vibration.
• Hydraulically balanced impellers reduce radial loads, prolonging seal and bearing life.
• Multiple material selections allow for customized solutions to meet specific application requirements.

SHAFT and SHAFT SLEEVES

• Vertical configuration of the shaft eliminates shaft slope and related distortions, promoting longer seal and bearing life compared to conventional horizontally mounted units.
• Shaft sleeves are available in a wide variety of metallurgies, such as steel, bronze, etc.
• Sleeve protects the shaft from corrosion and wear, extending the overall life of the shaft and usable life of the pump.

SUCTION BAFFLE

• Integrally cast suction baffle directs flow directly into the eye of the impeller for a more even distribution flow, eliminating pre-rotation and suction losses and creating a smooth, quiet pump operation.

VOLUTE

• Compensated double volute design virtually eliminates radial forces caused by a hydraulic imbalance inherent in pump volutes.
• Double volute design extends seal and bearing life, minimizing noise and vibration, and improving operating efficiency.
