GRUNDFOS DP RANGE
The Grundfos DP pumps are designed for pumping drain water and groundwater from installations in or around private housing, farms, small industry, etc.
The portable Grundfos DP pumps are also ideal for flood-relief applications and as utility pumps in farming, industry, etc.
The 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 size - the maximum free passage through the DP pumps. The strainer is easy to dismantle for cleaning or inspection of the pump hydraulics.


Easy-adjustable impeller
The impeller of 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.
Installation
The Grundfos DP pumps with motors up to and including 1.5 kW are fitted with a 90°-angled discharge port with a 2" inside tread for mounting of a rigid or flexible discharge pipe. These models are for free-standing or portable use only.
Grundfos DP pumps with 2.6 kW motors are fitted with a standard DN 65 flange. Flanged models can be mounted free standing or on an auto-coupling system.
GRUNDFOS EF RANGE
The Grundfos EF pumps are designed for pumping wastewater without toilet waste from private dwellings. These pumps are also suitable for pumping liquid manure from farms, and for a variety of industrial applications.
The EF pumps are designed for free-standing installation. The pumps are fitted with an integrated three-leg stand that keeps the suction inlet well clear of the pit bottom. The EF pumps are capable of handling solids of up to 30 mm size.


Efficient channel impeller
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.

GRUNDFOS SE RANGE
The Grundfos SE pumps are designed for pumping surface water, wastewater, and sludge, containing industrial wastewater.
The Grundfos SE pumps are also ideal for installation in underground parking areas, car wash plants, and similar situations where a robust, dependable pump capable of dealing with large quantities of wastewater is required.


Self-cleaning channel impeller
The Grundfos SE pumps are fitted with a closed single-channel impeller capable of handling moderate amounts of fibres and solids of up to 50 mm size.
The Grundfos channel impeller pumps provide high efficiency and excellent non-clogging capabilities. The channel impeller of the SE range has a free passage of 50 mm. Channel impeller pumps are ideal for heavy-duty operation and for pumping large quantities.
The 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.
Installation
The Grundfos SE pumps are fitted with a standard DN 65 discharge flange. The pumps can be installed free standing or on an auto-coupling guide-rail system in a pump pit.
GRUNDFOS SEV RANGE
The powerful Grundfos SEV pumps are designed for pumping wastewater with a high content of solids and fibres, including toilet waste, from pump pits in connection with private dwellings or other small building complexes.
Highly efficient SuperVortex impeller
The SEV pumps are fitted with a patented Grundfos SuperVortex impeller, which is extremely efficient in handling solids and fibres. The SEV pumps have a free passage of 65 mm.


No clogging or jamming
In a pump fitted with a Grundfos SuperVortex impeller, the flow takes place entirely outside the impeller.
The design of the impeller ensures that long fibres pass freely through the pump without getting caught and without causing clogging or jamming. This means less downtime and overall higher pumping efficiency.
