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 apolypropylene 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.

Overview
The Grundfos SQ 3” submersible pumps offer a wide performance range, making it easy to find a model that will suit your individual requirements.
The SQ is a compact, 3″ multistage centrifugal pump that can be installed in a borehole no larger than the pump itself. With their built-in electronics, SQ pumps are very easy to install and operate. They guarantee a reliable water supply at all times.
Equipped with permanent magnet motors, these flexible and compact pumps offer excellent efficiency levels and will supply pump heads up to 200 m.
If the SQ pump is connected to the Grundfos CU 301 control box, it enables the creation of a constant pressure water supply.
Applications
SQ/SQE pumps are suitable for both continuous and intermittent operation for a variety of applications:
- Ground water supply – private housing, small waterworks, small irrigation systems
- Liquid transfer in tanks
- Pressure boosting
- Environmental applications – remedial pumping or sampling
- Garages and petrol stations.
Features and benefits
- Dry-running protection
- Permanent magnet motor with high efficiency
- Wear resistance from floating impellers
- Protection against upthrust
- High flow velocity
- Soft-starts reduce wear on motor
- Over- and under-voltage protection
- Overload protection
- Over-temperature protection.
Additional features of the SQE
- Variable motor speed controls (with connection to the CU 301)
- Connection to the CU 301 for two-way communication.

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.

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
