Grundfos LS
Horizontal Split Case Pumps
The Grundfos LS horizontal split case pump is a single-stage, non-self-priming,
between bearing, centrifugal volute pump.
The axially split design allows easy removal of the top casing and access
to the pump components (bearings, wear rings, impeller, and shaft seal)
without disturbing the motor or pipework.
The independent bearing housing allows for ease of maintenance without removing the top casing.
The double volute design reduces the radial load on the shaft, extending component life,
minimising vibration and providing quiet operation.
The Grundfos LS pump also offers high pump efficiencies throughout the range.
High energy efficiency along with long pump life and easy maintenance add up to low life-cycle costs.
The Grundfos LS pump is available in three configurations
- Pump with motor and baseframe
- Pump with baseframe
- Bare shaft pump only
The Grundfos LS pump is ideal for custom applications and is available in a wide range of variants.
The high efficiency and low life cycle costs make the LS ideal for any commercial building,
water utility or industrial project.
