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 SEG range of grinder pumps from Grundfos is specifically designed for pumping effluent and untreated sewage in small communities or sparsely populated areas with no sewer systems or where gravitation systems are unsuitable.
Pressurised systems are the perfect choice for transfer of effluent and sewage, and the SEG range combines cost-effectiveness with maximum protection for the environment by facilitating the use of smaller pressure pipes for minimal investment costs.

The SEG range is designed to reduce energy consumption and to keep downtime costs to a minimum, while maintaining peak performance throughout the system life.
Applications
The Grundfos SEG pumps are specifically designed for pumping untreated wastewater from domestic, commercial or municipal sources. The high discharge pressure enables transfer of wastewater over longer distances.
Features and benefits
- Cable plug connection
- Efficient grinder system
- SmartTrim impeller adjustment
- Unique clamp connection
- Specially designed lifting handle
- Unique cartridge shaft seal
- Modular design
- Heavy-duty ball bearings.

Grundfos EF pumps are designed for pumping wastewater (excluding toilet waste) from private dwellings. They are also suitable for pumping liquid manure from farms, and for a variety of industrial applications.

The EF pumps are designed for free-standing, hook-up or auto-coupling installation. The pumps are fitted with an integrated three-legged stand. They are capable of handling liquids containing solids of up to 30 mm in size.
The Grundfos EF pumps are fitted with an open single-vane impeller with excellent solids-handling capabilities.
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
- Unique cartridge shaft seal
- Modular design
- Heavy-duty ball bearings
- Short rotor shaft.
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.
