Product Overview
The Grundfos DP and EF pumps are purpose-built for pumping drainage water, surface water, and wastewater containing small impurities. These pumps serve installations in residential properties, agricultural settings, commercial buildings, and small industrial facilities across Dubai and the UAE.
Available with AUTOADAPT Technology
Both pump ranges come with optional AUTOADAPT features that eliminate external sensors, switches, and cables from the well pit. This advanced technology simplifies installation, commissioning, and daily operation while significantly increasing system reliability.
Grundfos DP Range – Portable Utility Pump (0.9 – 2.6 kW)
The DP range serves as a versatile portable utility pump designed for:
- Drainage and surface water removal
- Groundwater pumping
- Industrial process water handling (without solids and fibres)
DP Range Installation Options
- Portable, free-standing operation
- Auto-coupling system installation
DP Range Solids Handling
The DP pumps feature a suction strainer that allows passage of solid particles up to 10 mm maximum. This strainer serves as the pump’s base and can be easily dismantled for cleaning or hydraulic inspection.
Grundfos EF Range – Excellent Solids Handling (0.6 – 1.5 kW)
The EF range excels at pumping effluent and wastewater containing higher solid content:
- Drainage and surface water with small impurities
- Liquid manure from farms
- Wastewater with fibres (laundries)
- Wastewater without toilet discharge (residential and commercial)
EF Range Installation Options
- Free-standing operation
- Auto-coupling system installation
EF Range Design Features
- Integrated three-leg stand keeps suction inlet clear of pit bottom
- Handles solids up to 30 mm in size

Key Features and Benefits
Cartridge Shaft Seal
The efficient double cartridge shaft seal system delivers longer operation time with reduced downtime. The easily accessible design simplifies maintenance procedures.
Watertight Cable Plug
A polyurethane-filled stainless steel cable plug connection provides a watertight and durable seal around cable leads. This robust design ensures water cannot reach the motor even under adverse handling or accidental breakage. Simply pull out the plug during servicing—no special tools required.
Ergonomic Lift Handle
The ergonomic lift handle provides optimum point-of-balance lifting. The motor unit rotates 180° on the pump housing to protect auto-coupling sealing during handling.
Patented SmartTrim Impeller Adjustment
When impeller wear occurs, the patented SmartTrim system enables easy adjustment, service, and optimisation without dismantling the pump. No special tools required to maintain peak performance.
Stainless Steel Clamp Assembly
The unique clamp assembly system allows quick disassembly of the pump from the motor unit. The stainless steel clamp requires no special tools to loosen, enabling fast field service without cleaning the casing to access bolts.
Thermal Protection System
Thermal switches in motor windings protect against overheating, ensuring long pump lifetime. AUTOADAPT versions include built-in motor protection for additional safety.
