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.

Grundfos EF pumps are designed for pumping wastewater (excluding toilet waste) from private dwellings. They are also suitable for pumping liquid manure from farms, and for a variety of industrial applications.

The EF pumps are designed for free-standing, hook-up or auto-coupling installation. The pumps are fitted with an integrated three-legged stand. They are capable of handling liquids containing solids of up to 30 mm in size.

The Grundfos EF pumps are fitted with an open single-vane impeller with excellent solids-handling capabilities.

Impeller clearance can be adjusted by tightening or loosening the adjustment screws at the bottom of the suction cover. Adjustment can be carried out without dismantling the pump.

Applications

The pumps are suitable for:

• Drainage
• Effluent
• Wastewater not containing discharge from toilets.

Features and benefits

• Cable plug connection
• Unique clamp connection
• Specially designed lifting handle
• Unique cartridge shaft seal
• Modular design
• Heavy-duty ball bearings
• Short rotor shaft.

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 JP pump is a self-priming, single-stage centrifugal pump with axial suction port and radial discharge port, G 1 or Rp 1. The pump has a built-in ejector with guide vanes for optimum self-priming properties.

JP pumps are available in two material variants.

Material variant A: Cover plate, motor stool and base plate in one unit. The handle is fitted crosswise. Both elements are made of composite material.

Material variant B: Stainless steel cover plate, aluminium motor stool and stainless steel base plate, all separate parts.

The robust design makes the pump suitable for fixed installation. The custom-built composite handle is fitted lengthwise.

The pump is directly coupled to a special fan-cooled asynchronous Grundfos motor that is adapted to the pump performance Single-phase motors have a built-in thermal switch and require no additional motor protection Three-phase motors require external motor protection

Applications

Built for a long, trouble-free working life, the small and handy Grundfos jet pump is suitable for a wide variety of water supply and transfer duties in home, garden and hobby applications as well as in agriculture, horticulture and small-scale service industries.

When used in combination with a pressure control or tank, the JP pump is ideal for small water supply systems.

Features and benefits

• Self-priming
• Stable operation even if there is air in the liquid
• Ideal for small water supply systems
• Compact and handy.
