DP Range – The Portable Utility Pump

The Grundfos DP range is designed for pumping drainage and surface water, groundwater, and industrial process water without solids and fibres. These versatile pumps serve farms, private housing, and small industry with portable convenience or permanent auto-coupling installation.

Suction Strainer Base DP pumps feature a suction strainer that serves as the pump base, allowing passage of solid particles up to 10mm maximum. The strainer is easily dismantled for cleaning or inspection of pump hydraulics.

Semi-Open Multivane Impeller The easily adjustable impeller handles solids up to 10mm while maintaining high efficiency and reliable performance.

Application Suitability:

  • Drainage and surface water removal
  • Groundwater pumping
  • Industrial process water (without solids/fibres)
  • Construction site dewatering
  • Basement flood control

EF Range – Excellent Solids Handling

The Grundfos EF range handles effluent and liquids with small impurities, including fibrous wastewater from laundries and liquid manure from agricultural operations. The open single-vane impeller design provides superior solids handling capability.

Integrated Three-Leg Stand The EF pumps feature a built-in stand that keeps the suction inlet well clear of the pit bottom, preventing debris ingestion and ensuring reliable operation.

Open Single-Vane Impeller Capable of handling solids up to 30mm, the single-vane design minimizes clogging while efficiently moving effluent containing fibrous materials.

Application Suitability:

  • Effluent with small impurities
  • Drainage and surface water
  • Liquid manure from farms
  • Laundry wastewater (fibrous content)
  • Wastewater without toilet discharge
  • Private homes and commercial buildings

Key Features & Benefits

AUTOADAPT Technology Available models with AUTOADAPT features eliminate all external sensors, switches, and cables from the wet well pit. Installation, commissioning, and operation are simplified while reliability is significantly increased. AUTOADAPT versions include built-in motor protection.

Patented SmartTrim Impeller Adjustment The SmartTrim system enables extremely easy adjustment, service, and optimization of the impeller to maintain peak performance. Adjustments can be made without dismantling the pump and require no special tools.

Double Cartridge Shaft Seal The efficient double cartridge shaft seal system ensures longer operation time with less downtime. The easily accessible design simplifies service and seal replacement.

Watertight Cable Plug The polyurethane-filled stainless steel cable plug connection provides a watertight and durable seal around cable leads. Even adverse handling or cable breakage will not result in water entering the motor. Simply pull out the plug when servicing—no special tools required.

Stainless Steel Clamp Assembly The unique clamp system ensures quick and easy disassembly of the pump from the motor unit. Loosening the stainless steel clamp requires no special tools, enabling fast field service without cleaning the casing to access bolts.

Ergonomic Lift Handle Designed for optimum point-of-balance, the ergonomic handle facilitates safe handling. The motor unit rotates 180° on the pump housing, protecting the auto-coupling sealing during installation and removal.

Thermal Switches & Motor Protection Thermal switches in the motor windings protect against overheating, ensuring long motor lifetime. AUTOADAPT versions include additional built-in motor protection for enhanced reliability.


Installation Options

Portable Freestanding Both DP and EF ranges can be used as portable pumps for temporary applications or locations requiring flexibility.

Auto-Coupling System Permanent installation using auto-coupling enables pump removal for service without entering the wet well, ensuring safe and efficient maintenance access.
