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 basic CR pump range, which can be applied in almost any industrial solution, is already in itself the broadest range available. Through our modular approach, we have made it even broader.
The basic CR pump range is available in four different materials: cast iron, two grades of stainless steel, and all-titanium. There are eleven flow sizes, capable of producing up to almost 50 bar of pressure, and with a variety of shaft seals, rubber materials and supply voltages.
Pump parts which are typically vulnerable to difficult liquids or particularly demanding operating conditions can be optimised for their purpose and designed for specific requirements.
Applications
CR pumps provide a complete range of pump solutions so that all applications, industrial and domestic, can benefit from the Grundfos touch. The applications that can be covered include the following:
- Process water systems
- Washing and cleaning systems
- Seawater systems
- Pumping of acids and alkalis
- Ultrafiltration systems
- Reverse osmosis systems
- Swimming baths.
Features and benefits
- Reliability
- High efficiency
- Service-friendly
- Space-saving
- Suitable for slightly aggressive liquids
- High corrosion resistance
- Single-pump solution making high pressures possible.

Impeller clearance can be adjusted by tightening or loosening the adjustment screws at the bottom of the suction cover. Adjustment can be carried out without dismantling the pump.
Applications
The pumps are suitable for:
- Drainage
- Effluent
- Wastewater not containing discharge from toilets.
Features and benefits
- Cable plug connection
- Unique clamp connection
- Specially designed lifting handle

The SB and SBA pump is a submersible booster pump for the pumping of clean water. It is especially suitable for rainwater applications and private wells. The pump is available in two versions:
SB
The Grundfos SB is a submersible pump for the pumping of clean water. It is designed for use in domestic applications. The pump itself is very silent, and when installed underground in a rainwater collecting tank or well, noise will never become an issue. The SB pump requires an external controller, like Pressure Manager, for automatic operation.
Features and benefits
- Flexible selection – Pump + controller
- Complete control and monitoring
- Easily accessible controller – for service & replacement
SBA
The new Grundfos SBA is a complete all-in-one unit. It is built on the proven SB platform, but comes with an integrated control unit – eliminating the need for an external pump controller.
The SBA is literally a plug- and pump solution. Once installed and connected to the piping, all you need to do is switch on the pump.
Features and benefits
- Easy selection – one unit
- Easy installation – one unit
- Flexible installation – no controller inside the house
All SB and SBA pumps are available in two main variants
- With integrated suction strainer (1 mm mesh)
- Or with side inlet/flexible suction hose with floating suction strainer (1 mm mesh).
All variants are available with or without float switch:
The float switch offers automatic operation and dryrun protection, stop at low water level, ensuring that surface fragments do not enter the strainer.
Applications
The SB and SBA pump is a submersible booster pump for the pumping of clean water. It is especially suitable for rainwater applications.
Features and benefits
- Noiseless operation
- High reliability
- Integrated protection.
- Floating suction strainer The model with floating suction strainer always draws the water from just below the water surface where the water is clean and free from solid particles.
Additional features of the SBA:
- Simplicity – all-in-one unit
- Easy installation – no external control unit
- Integrated dry-running protection
- Automatic restart after dry-running
- Lifting eye

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.
