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.

Grundfos RC pumps are used for the circulation of liquid refrigerants in refrigeration systems.

The RC pumps have been designed and optimised for use with CO₂ as a refrigerant, but can also be used with NH₃ (Ammonia) and selected HFCs.

The low required NPSH and the fact that no traditional loss-generating protective devices are needed can help system designers to reduce the dimensions and cost of the system. The RC pumps have an innovative design in stainless steel which makes specially suited for use with high pressure refrigerants (CO₂) – the pump has only one seal between the refrigerant and ambient sides. A version with welded connections eliminates the use of counter flanges and possible leakage in flange connections.

Applications

Grundfos RC pumps are designed for the circulation of liquid refrigerant in refrigeration systems.

Features and benefits

• Barrel-type, semi-hermetic, high-pressure design
• Multistage centrifugal pump
• Canned motor (no shaft seals)
• High energy efficiency
• Wide range for variable speed capacity control
• Low NPSHR and robust to vapour bubbles in inlet
• Installation and service friendly
• Compact and low weight.

DWK and DPK are submersible pumps designed for dewatering and drainage applications. The cast-iron construction and the hydraulic design contribute durability and high efficiency. The differences between the DWK and DPK pump ranges lie in the discharge arrangement and the installation type. The DWK is designed with a top discharge pipe and suction strainer, and is thus more suitable for temporary installation, whereas the DPK has a side discharge and a ring-stand or auto coupling (as accessories), and is suitable for permanent installations.

Applications

DWK/DPK are excellent pumps for dewatering and draining applications. The combination of compact design with high-pressure capability makes the pumps suitable for use in pits, whether for temporary or fixed installation. The installation design options provide the flexibility needed to cover many needs. Applications include:

• Construction sites
• Excavations
• Tunnels
• Fish ponds
• Drainage pits.

Features and benefits

• Durability
• High efficiency
• Installation flexibility
• High-pressure capabilities, cost-effectiveness.

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
