Buffalo Pumps - Model VCRE -Vertical Lube Oil Pumps

The VCRE family of pumps is designed specifically with these requirements in mind. The VCRE lube oil pump is a vertically submerged pump that utilizes an ANSI standard hydraulic construction, enclosed bearing housing, and welded piping construction which eliminates the inherent maintenance and leakage problems associated with other pumps.

During operation, axial and radial thrust loads are controlled by Buffalo’s exclusive modified casing volute and impeller design.

Buffalo Pumps is backed by extensive field-proven experience in designing pumps to handle any lube oil application. This experience also provides flexibility in assisting OEM’s contractors and end-users in designing a sound installation that ensures maximum life.

vcre_image2.jpgOur on-site lube oil test tank gives Buffalo Pumps the ability to simulate field conditions in order to properly select VCRE pumps for the critical applications they are installed in. The lube oil test tank also allows for performance verification of any vertical lube oil pump if desired.

The VCRE pump design has been a mainstay in the power generation industry for over 60 years.

Our robust design on these vertical pumps has allowed for them to be implemented on various skid designs with several different turbine manufacturers.

The VCRE pump is also available with an open impeller (VCRO style) for heavier duty applications including light slurries and sumps.

• Impellers for the VCRE were designed specifically to provide low axial thrust to provide long life bearings.
• Thrust bearing life is maximized through casing, impeller, and impeller balance chamber design to reduce axial forces on the bearing. Impeller position within the casing is maintained in a specific location.
• Bearings can be either grease or oil lubricated. Radial bearing life is maximized through our special casing design to reduce radial hydraulic thrust.
• Our shafts are designed such that the first critical speed is a minimum of 20% higher than the operating speed. This rigid shaft design provides worry-free operation.
• Close tolerance machined and rabbeted fits are utilized on all major components. This facilitates the ability to rebuild the original pump assembly in the field.
• Coverplates are a minimum of 7/8” thick to provide a rigid, flat and leakproof connection to lube oil tanks. Coverplate dimensions can be customized to fit customer requirements.
• Motor stands are designed to allow most motors to be shipped mounted to the pump. All pump/motor assemblies are factory aligned to ensure alignment
• capabilities in the field.
