LaBour LVA
Heavy duty design ANSI pump, available in a wide range of metallurgies. Standard design includes lowest “Shaft Flexibility Factor (L3/D4)” in the industry, highest bearing “Basic Dynamic Load Rating”, power end L10 life in excess of 100K hours and “Flinger” oil lubrication system.
Applications
The LVA ANSI-standard pump will handle corrosive, toxic
and abrasive process liquids such as acids, bases and solvents.
● Agriculture
● Chemical Transfer
● Petro-Chemical
● Pulp & Paper
● Plastics
● Refining
● Pharmaceutical Plants
A wide range of alloys, options and sealing systems makes it
an ideal choice for almost any application.

Features
- The LVA casing is a self venting, top cenerline discharge with a fully confined gasket.
- Dual oil level monotoring systems; “Bullseye Sight Glass” and clear “Trico® Optimatic” constant level oiler.
- Two heavy duty, back-to-back mounted, 7300 series, angular contact bearings, providing an industry leading L10 life in excess of 100,000 hours.
- Largest shaft diameter (D) and shortest impeller overhang (L), resulting in the lowest “Shaft Flexibility Factor (L3/D4)” in the industry.
- Flinger type lubrication system creates a constant oil mist cascading over the radial & thrust bearings, resulting in cooler running bearings than other manufacturers flooded lubricated bearings.
- Integral impeller pump out vanes reduce stuffing box pressure, extending mechanical seal and bearing life.
- A Low Flow Impeller is available for select sizes of Pump Group I, II & III pumps. This Low Flow Impeller helps extend MTBF for those applications operating close to shut-off on a standard pump.
