The Grundfos DW pumps are robust, portable submersible pumps with a vertical discharge port.
Available with motors from 0.8 to 20 kW, they are designed to handle dewatering at construction sites, at excavation sites, in building drainage and in similar applications where there is a need to pump raw water or/and at high pressure.
DW main parts are made of aluminium in order for them to be as light as possible. This factor, in combination with the compact design and the high-pressure capabilities, make DW pumps portable and easy to handle. The semi-open type impeller is made of high-chrome stainless steel (550HB) in order to increase wear resistance. DW.50.08 (only) has a polypropylene motor housing.
DW pumps are excellent for dewatering and draining jobs. The portable design, wear resistant parts and high pressure capabilities ensure the reliability, sustained performance, user-friendliness and ease of servicing that are necessary in demanding dewatering applications at sites such as:
- Construction sites
- Steel works
- Fish ponds
- Underground parking drainage Industrial drainage pits.
Features and benefits
- Ease of servicing High pressure capabilities Control options.

The Grundfos HS 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 HS 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 HS pump is available in three configurations – pump with motor and baseframe, pump with baseframe, and bare shaft pump only.
The HS 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 HS ideal for any commercial building, water utility or industrial project.
Grundfos HS horizontal split case pumps are typically used in these applications:
- Air-conditioning/heating systems
- Public water supply
- District cooling/heating plants
- Cooling systems
- Public waterworks
- Process cooling
Features and benefits
- Easy to service: split case design
- Double suction minimises axial load,which extends the life of the wear rings, shaft seals and bearings
- Double volute reduces radial forces and minimises noise and vibration
- Independent bearing housing design allows access to the pump components without removing the top half of the casing
- High energy efficiency
- Low life-cycle costs
- Many product variants available.
