The AeroJet is a self-aspirating aerator that keeps aerobic treatment processes running and also helps to avoid odour problems in wastewater storage, as anaerobic zones can be eliminated.

AeroJets are a flexible way of providing both mixing and aeration with the same device. AeroJets are easy to install, operate and maintain, as they do not require any blowers, air distribution piping or control valves.

The flexibility of the AeroJet offers distinct advantages for upgrading aeration capacity to meet increased oxygen demands. It can be used either alone or as a supplement to existing aeration equipment.

AeroJets are available in many different sizes to ensure that all needs can be met, no matter what the size and shape of the tank.

Applications

AeroJets are ideal in applications where aeration is needed to enhance biological processes, to avoid odour problems, or to supply oxygen in:

• Municipal or industrial WWTP
• Stabilisation and equalisation tanks
• Fish farms

Or in applications where flexible oxygen supply is essential:

• Refurbishment of treatment plants
• Boosting oxygen supply at peak loads
• Avoiding oxygen depletion in lakes or channels

Features and benefits

• Handles both aeration and mixing
• Self-aspirating aerator – no need for additional air distribution pipes, blowers or valves
• Submerged aerator increases oxygen transfer time
• Submerged installation reduces noise and limits aerosol formation at the tank
• Available as a free-standing unit or with the pump on an auto-coupling
• Can easily be installed or repositioned even while processes are running
• Fit all tanks, regardless of size and shape
• Made completely in stainless steel for strength
• Fed by a submersible wastewater pump of the SL, SE or S types
• Large free passage – no clogging

The Unilift CC is a single-stage submersible drainage pump, designed for the pumping of drain water and grey wastewater. The Unilift CC can pump down to a water level of 3 mm above the floor by removing the strainer. The Unilift CC is suitable for permanent as well as temporary installation. The Unilift CC is fitted with a non-return flap valve in the outlet in order to prevent backflow from the piping system. An adaptor ensures good connections to 3/4”, 1” or 1 1/4” outlets.

The strainer is made of stainless steel, while the main pump parts, e.g. the sleeve and pump housing, are made of moulded composite materials.

The Multibox B-CC7 is an Unilift CC combined with further elements such as a hose with Storz coupling, an adaptor for threaded Storz coupling and a box with perforated-mesh sides to be used as a pre-strainer for the pump. It is the perfect solution for use as an emergency kit for single family houses in the event of flooding.

Applications

The Unilift CC is designed for the pumping of the following:

• Water and rainwater in horticulture
• Water from rivers and lakes
• Rainwater, drainage water and water from flooding
• Water for filling/emptying containers, ponds, tanks, etc.
• Effluents from showers, washing machines and sinks below sewer level
• Pool water
• Ditch drainage water
• Groundwater (lowering applications)
• Effluents from viaducts, underpasses, etc.
• Drainage water from garage sprinkler systems.

Features and benefits

• Composite materials
• Stainless steel strainer
• Self-venting valve in handle
• Available with level switch

The Unilift AP and Unilift AP Basic are submersible drainage pumps designed for both temporary/portable installation and permanent free-standing installation. These single-stage pumps are made mostly of stainless steel. All types are available in either single phase or three phase versions and for 50 or 60 Hz power supply.

The number in the type designation, e.g. AP12, indicates the spherical particle size that can pass through the pump.

All Unilift AP and AP Basic pumps are fitted with a plug for connection to the mains.

Unilift AP is a single stage pump with either semi-open impeller (AP12) or with vortex impeller (AP35 and AP50). All Unilift AP pumps are fitted with a stainless steel sleeve for cooling during operation. The strainer at the bottom prevents particles larger than the pump is designed for from entering the pump. The strainer is clipped onto the pump housing. All Unilift AP pumps can be supplied with or without float switch, for automatic or manual operation. Pumps with an ”A” in the type designation are fitted with a float switch. 3-phase versions have an additional starter box connected to the float switch. The outlet is positioned at the top of the pump and is available in Rp 1 1/2 to Rp 2.

An optional non-return flap valve can be fitted in the outlet in order to prevent backflow.

Unilift AP Basic pumps are single-stage pumps (AP35B, AP50B) with vortex impeller. All Unilift AP Basic pumps are made of stainless steel, with a composite baseplate. The Unilift AP Basic range is designed for submerged operation, either free-standing on the base plate or installed using an auto coupling. The pump inlet is designed to prevent to large particles from entering the pump. The base plate is clipped on by means of four clips hidden under the composite ring at top of the pump housing. The ring prevents dirt from sticking to the clips. All Unilift AP Basic pumps can be supplied with or without float switch, for automatic or manual operation. Pumps with an ”A” in the type designation are fitted with a float switch. The outlet is positioned at the side of the pump and is R 2.

Applications

• Water and rainwater in horticulture
• Water from rivers and lakes
• Rainwater, drainage water and water from flooding
• Water for filling/emptying containers, ponds, tanks, etc.
• Effluents from showers, washing machines and sinks below sewer level
• Pool water
• Ditch drainage water
• Groundwater (lowering applications)
• Domestic effluents from septic and sludge-treating systems
• Liquids containing fibres from light industry, laundries, etc.
• Effluents from viaducts, underpasses, etc.
• Drainage water from garage sprinkler systems

Features and benefits

Unilift AP is for permanent or temporary free-standing installations. Most components are made of stainless steel. Cable fitted by means of a plug. Available in both automatic and manual versions. Single-phase versions have an integrated thermal switch.

S pumps form the backbone of many sewage systems. They are selected for their strength, their durability, and for innovative features such as the SmartTrim impeller clearance adjustment system and the Smart Seal for leakage prevention.

The SmartTrim system used on the S-pumps makes it easy to adjust the factory-set impeller clearance and thus to maintain maximum pump efficiency.

The Grundfos SmartSeal Auto-coupling gasket provides a completely leak-proof connection between the pump and the base unit of the auto-coupling system. The shaft seal is capable of rotating in either direction. When the pumps are installed with separate pipework, sludge sedimentation can be avoided by back-flushing the system at regular intervals.

Applications

The pumps are suitable for the following applications:

• Transfer of unscreened raw sewage
• Transfer of raw water
• Pumping of water containing sludge
• Pumping of industrial effluent.

Features and benefits

• Wide range
• SmartTrim
• Operation with/without cooling jacket
• Submerged or dry installation
• Channel and vortex impellers
• Built-in motor protection
• SmartSeal
• Large free passage
• SuperVortex impeller.
