Close Coupled & Split Coupled Vertical In Line Pumps (LVI, LVS SERIES)
The Lubi LVI are non-self priming, single-stage, vertical in-line, close-coupled type centrifugal pumps, where as LVS are non-self priming, single-stage, vertical in-line, split-coupled type centrifugal pumps. They have radial suction and discharge port.
Vertical in-line pumps offer largest floor space saving compared to End suction & Horizontal split case pumps.
Salient Features :
- LVS pumps can use industry standard motor designed for vertical operation.
- The axially split, spacer type rigid coupling allows for the mechanical shaft seal maintenance without disturbing pump or motor.
- These pumps are available with two types of mechanical seal arrangements, internal and external. In both arrangements seal can be removed easily and quickly for servicing without disturbing motor or pump from the piping.
- The high performance external type mechanical seal arrangement combines the advantages of a multi-spring balanced seal with premium quality and is the easiest to remove. The inside type mechanical shaft seal arrangement provides an economical alternative.
- Generous venting of seal chamber and liquid flushing at seal faces is provided by gland plate flush connections.
- The pump impellers are dynamically balanced to grade 6.3 of ISO 1940.
- Rigid volute casing with ribs integrally cast with equal suction and discharge flange size.
- Gauge, flush and drain connections are provide on the volute casing.
- Straighting vanes near the pump suction provide efficient suction performance and quite operation.
- Coupling access opening are guarded with a well designed coupling guard.
