Backwashing refers to the reverse-pumping of water, for example for the periodic washing of filters. Grundfos can supply pumping solutions that deliver the very strong force with well-executed flush times and speeds required for effective backwashing.
Backwashing is a form of preventive maintenance to prevent further clogging of the filter medium. Backwashing in water treatment plants is an automated process, usually run by programmable logic controllers (PLCs). The backwash cycle is usually triggered when the differential pressure over the filter exceeds a set value.
Grundfos can supply pumping solutions to cope with the hugely varying flow requirements for backwashing, ranging from huge split-case and mixed-flow pumps, where the focus is on moving water rather than added pressure, to our highly successful vertical multistage centrifugal pump (CR) – and covering all performance requirements in between.
Grundfos can supply the specialist expertise to help meet your performance objectives, from the initial identification of needs, to the selection, installation, operation, and maintenance of the pumping solution. Grundfos commissioning agreements ensure correct installation and service agreements cover all eventualities, from routine maintenance to spare parts and pump audits.
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

Grundfos’ new range of GHP (Grundfos Hygienic self-Priming) pumps takes efficiency and durability to new levels in sanitary processes.
The pumps are based on the well-known HILGE technology and are further optimised to offer reliable operation even under the tough conditions encountered in cleaning processes.
The single-stage self-priming GHP pumps combine the best of the F&B-HYGIA end-suction pumps with the reliable HILGE technology. The result is an optimised pump range that comes with increased efficiency compared to traditional side-channel pumps and can be counted on for long operational life.
One pump – More applications
Due to the robust construction of the new GHP pumps they are able to handle liquids with a high content of air as is the case in CIP return systems.
In effect, this means that the same pump can be used for product conveyance as well as for the cleaning processes. Compared to side-channel pumps, GHP pumps are also less sensitive to handling products containing particles.
Low noise operation
The GHP pumps feature a new, unique hydraulic technology that allows the impeller to be adjusted to accommodate exact duty-point requirements.
This translates into a noise level significantly lower than compared to traditional side-channel pumps.
Specially designed for sanitary applications
The all-stainless steel GHP pumps have been specially designed for trouble-free operation in sanitary processes such as:
- Cleaning processes (CIP return)
- Evacuation of tanks and pipes
- Pumping liquids with a high gas content
- Pumping liquids in Food and Beverage industries.

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
