Grundfos UNILIFT APG – cutting tool pump for domestic wastewater

The Grundfos UNILIFT APG is a single-stage submersible pump equipped with a grinder that grinds degradable solids into small pieces, allowing them to pass through pipes of relatively small diameter. The pump is ideal for sparsely populated areas where gravity sewer systems are not available, and for applications with large differences in terrain.

Cutting tool Grinds solid particles into smaller tubes.
Durable materials Cast iron and stainless steel for long life.
Flexible installation Submersible installation on auto coupling or freestanding.

Main advantages of UNILIFT APG

  • A cutting tool (grinder) for grinding destructible solid particles.
  • Allows the use of smaller diameter pipes.
  • Ideal for sparsely populated areas without gravity sewerage.
  • Suitable for single or two-family houses, residential buildings and sites with large differences in terrain.
  • Durable materials – cast iron and stainless steel for reliable operation.
  • Smooth surface to prevent dirt and impurities from sticking.
  • Four corrosion-resistant screws secure the motor to the pump housing for easy maintenance.
  • Possibility of submersible installation of auto coupling with guide rails or freestanding installation.

Applications

  • Pumping domestic wastewater in areas without a gravity sewer system.
  • Single or two-family houses with toilets and sanitary appliances below the sewer level.
  • Residential buildings and complex sites with a central pumping station.
  • Sites with large differences in terrain where gravity drainage is not possible.
  • Installation in pumping stations with auto-coupling and guide rails.
  • Freestanding installation in wells or tanks.

Suitable liquids

  • Domestic wastewater containing fecal matter and degradable solids.
  • Greywater from washing machines, sinks, showers and bathrooms.
  • Black water from toilets with fecal matter and hygiene products.
The pump is not suitable for liquids containing indestructible solid particles such as metal, glass or stones, flammable liquids such as oil or petrol, or aggressive chemicals.

General technical characteristics

Characteristics Value

Installation

UNILIFT APG is suitable for two types of installation:

  • Submersible Auto-Coupling Installation: The pump is mounted at the bottom of a collection tank with guide rails leading to the top. This allows for easy removal for servicing without emptying the tank.
  • Freestanding submersible installation: The pump is placed freely at the bottom of a well or tank. Suitable for smaller installations and temporary applications.
For permanent installation, the use of auto-coupling with guide rails is recommended for easier service and maintenance.

Operating modes

  • Automatic mode: With float for automatic start/stop between two liquid levels.
  • Manual mode: Without float, controlled by external controller or manual on/off.
  • Single-phase pumps: With built-in thermal protection and capacitor.
  • Three-phase pumps: Without built-in protection, require an external controller with motor protection.
UNILIFT APG is the ideal solution for sites where gravity drainage of wastewater is not possible and grinding of solids for transport through smaller diameter pipes is required.

Component materials

UNILIFT APG is constructed from durable materials such as cast iron and stainless steel, which ensure reliable operation and a long service life when pumping domestic wastewater with solid particles.

Component Material
Pump housing Cast iron and stainless steel
Cutting tool (grinder) Durable stainless steel
Impeller Vortex, stainless steel
Shaft Stainless steel
Camps Heavy-duty, pre-lubricated ball bearings
O-rings NBR rubber
Screws Corrosion-resistant stainless steel (4 pieces for the motor)
Cable Waterproof cable suitable for submersible work

Advantages of materials

  • Cast iron: High strength and durability for the main pump housing.
  • Stainless steel: Corrosion resistance for all components that come into contact with wastewater.
  • Stainless steel cutting tool: Ensures long life and reliable grinding of solid particles.
  • Vortex impeller: Reduces the risk of clogging and ensures efficient pumping of wastewater.
  • Heavy-duty bearings: Pre-lubricated and sealed for long life and quiet operation.
  • Smooth surface: Prevents dirt and impurities from sticking, reducing the need for maintenance.
  • Corrosion-resistant screws: The four screws that secure the motor to the pump housing are stainless steel for easy maintenance and long life.
All materials that come into contact with water are approved for handling domestic wastewater containing fecal matter and degradable solids.

Approvals and certificates

Grundfos UNILIFT APG has the necessary safety and quality approvals and certificates that guarantee reliable operation in domestic and commercial applications for pumping domestic wastewater.

Major approvals

  • CE marking: The pump complies with the requirements of European directives for safety, health and environmental protection.
  • EN 12050-1: Approval for use in lifting stations containing faecal matter (applicable to specific versions).
  • EN 60335-2-41: Safety standard for submersible sewage pumps.
  • ISO 9906: Standard for hydraulic performance of pumps.

Why are approvals important?

  • Health and Safety: Approvals ensure that the pump meets strict safety and reliability standards.
  • Regulatory compliance: The use of approved products is mandatory in many countries for installations related to wastewater disposal, especially in faecal matter plants.
  • Trust and quality: Certified products have passed rigorous testing and meet high quality standards.
  • EN 12050-1: This approval is particularly important for applications where the pump will be working with fecal matter and a higher level of reliability and safety is required.
Before installation, check whether the specific product number has the necessary approvals for your country or region. If additional certifications are required, contact Grundfos or your distributor.
