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.

The AeroJet is a self-aspirating aerator that keeps aerobic treatment processes running and also helps to avoid odour problems in wastewater storage, as anaerobic zones can be eliminated.
AeroJets are a flexible way of providing both mixing and aeration with the same device. AeroJets are easy to install, operate and maintain, as they do not require any blowers, air distribution piping or control valves.
The flexibility of the AeroJet offers distinct advantages for upgrading aeration capacity to meet increased oxygen demands. It can be used either alone or as a supplement to existing aeration equipment.
AeroJets are available in many different sizes to ensure that all needs can be met, no matter what the size and shape of the tank.
Applications
AeroJets are ideal in applications where aeration is needed to enhance biological processes, to avoid odour problems, or to supply oxygen in:
- Municipal or industrial WWTP
- Stabilisation and equalisation tanks
- Fish farms
Or in applications where flexible oxygen supply is essential:
- Refurbishment of treatment plants
- Boosting oxygen supply at peak loads
- Avoiding oxygen depletion in lakes or channels
Features and benefits
- Handles both aeration and mixing
- Self-aspirating aerator – no need for additional air distribution pipes, blowers or valves
- Submerged aerator increases oxygen transfer time
- Submerged installation reduces noise and limits aerosol formation at the tank
- Available as a free-standing unit or with the pump on an auto-coupling
- Can easily be installed or repositioned even while processes are running
- Fit all tanks, regardless of size and shape
- Made completely in stainless steel for strength
- Fed by a submersible wastewater pump of the SL, SE or S types
- Large free passage – no clogging

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 APG pumps are submersible pumps with a horizontal discharge port. They are specifically designed for the pressurised pumping of sewage and wastewater containing destructible solids. The pumps are equipped with a cutter system which cuts destructible solids into small pieces so that they can be led away through pipes of a relatively small diameter. The pumps are available with or without control box and level switch. Pumps without control box must be connected to a separate pump controller with motor starter.
Applications
The compact design makes these pumps suitable for both temporary and permanent installation. They are suitable for both free-standing installation and installation by means of an auto-coupling guide rail system. The APG pumps are designed for pumping:
- Sewage
- Wastewater
- Wastewater with high content of fibrous material
Features and benefits
- Integrated cutting system (APG)
- Dry or submerged installation
- Installation on auto coupling
- Sensors in windings

The Unilift AP and Unilift AP Basic are submersible drainage pumps designed for both temporary/portable installation and permanent free-standing installation. These single-stage pumps are made mostly of stainless steel. All types are available in either single phase or three phase versions and for 50 or 60 Hz power supply.
The number in the type designation, e.g. AP12, indicates the spherical particle size that can pass through the pump.
All Unilift AP and AP Basic pumps are fitted with a plug for connection to the mains.
Unilift AP is a single stage pump with either semi-open impeller (AP12) or with vortex impeller (AP35 and AP50). All Unilift AP pumps are fitted with a stainless steel sleeve for cooling during operation. The strainer at the bottom prevents particles larger than the pump is designed for from entering the pump. The strainer is clipped onto the pump housing. All Unilift AP pumps can be supplied with or without float switch, for automatic or manual operation. Pumps with an ”A” in the type designation are fitted with a float switch. 3-phase versions have an additional starter box connected to the float switch. The outlet is positioned at the top of the pump and is available in Rp 1 1/2 to Rp 2.
An optional non-return flap valve can be fitted in the outlet in order to prevent backflow.
Unilift AP Basic pumps are single-stage pumps (AP35B, AP50B) with vortex impeller. All Unilift AP Basic pumps are made of stainless steel, with a composite baseplate. The Unilift AP Basic range is designed for submerged operation, either free-standing on the base plate or installed using an auto coupling. The pump inlet is designed to prevent to large particles from entering the pump. The base plate is clipped on by means of four clips hidden under the composite ring at top of the pump housing. The ring prevents dirt from sticking to the clips. All Unilift AP Basic pumps can be supplied with or without float switch, for automatic or manual operation. Pumps with an ”A” in the type designation are fitted with a float switch. The outlet is positioned at the side of the pump and is R 2.
