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.
Applications
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
- Excavations
- Tunnels
- Steel works
- Fish ponds
- Underground parking drainage Industrial drainage pits.
Features and benefits
- Durability
- Portability
- User-friendliness
- Ease of servicing High pressure capabilities Control options.

DWK and DPK are submersible pumps designed for dewatering and drainage applications. The cast-iron construction and the hydraulic design contribute durability and high efficiency. The differences between the DWK and DPK pump ranges lie in the discharge arrangement and the installation type. The DWK is designed with a top discharge pipe and suction strainer, and is thus more suitable for temporary installation, whereas the DPK has a side discharge and a ring-stand or auto coupling (as accessories), and is suitable for permanent installations.
Applications
DWK/DPK are excellent pumps for dewatering and draining applications. The combination of compact design with high-pressure capability makes the pumps suitable for use in pits, whether for temporary or fixed installation. The installation design options provide the flexibility needed to cover many needs. Applications include:
- Construction sites
- Excavations
- Tunnels
- Fish ponds
- Drainage pits.
Features and benefits
- Durability
- High efficiency
- Installation flexibility
- High-pressure capabilities, cost-effectiveness.

The Grundfos DP pumps are designed for pumping drain water and groundwater from installations in or around private housing, farms and small industrial plants. These pumps are also ideal for flood-relief applications and as utility pumps in farming, industry, etc.
DP pumps are fitted with a suction strainer, on which the pump stands. The suction strainer allows for the passage of solid particles of up to 10 mm in size, which is the maximum free passage size through DP pumps. The strainer is easy to dismantle for cleaning or for inspection of the pump hydraulics.
The impeller for the DP range is of a semi-open multivane design. The impeller clearance can easily be adjusted simply by tightening or loosening the adjustment screws at the bottom of the suction cover.
Pumped liquids
The pumps are suitable for:
- Drainage and surface water
- Groundwater
- Industrial process water without solids or fibres.
Features and benefits
- Cable plug connection
- Unique clamp connection
- Specially designed lifting handle
- Unique cartridge shaft seal
- Modular design
- Heavy-duty ball bearings.

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.
Applications
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
- Irrigation.
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.
