The Best Cantilever Pump Solution For Your Application

At Egger, we strive to reduce your operations budget by supplying our pump technology which has the lowest life cycle cost available. Factors affecting life cycle cost include initial purchase price, maintenance over the life of the pump, and energy consumed.

Longevity, Reliability, and Energy Efficiency!

Recessed impeller vortex pumps are commonly used for abrasive slurries and/or solids handling applications since they have no submerged seals, bearings, bushings, or suction check valves. Cantilever pumps use an overhung shaft is supported by heavy-duty ball bearings that are located above the pumped liquid.

Cantilever pumps are designed to operate continuously, even when dry, without wearing out. There are also a variety of material options for corrosion and abrasion resistance such a Cast iron, Stainless steels (304, 316, Duplex, & Super Duplex), or 25.3% High Chrome iron.

These pumps ensure process reliability, high efficiency and low operating costs.

Egger pumps are available with a number of different impeller types, which change the nature of the flow through the pump.

The Turo® TA impeller is capable of pumping raw municipal sewage with a high content of fibers, that may clog conventional impellers.

Applications

MUNICIPAL: Cantilever pumps are widely used in municipal sludge, scum, & grit where abrasive slurries containing stringy solids must be passed without clogging or wear.

INDUSTRIAL: Typically found in chemical plants, wastewater treatment plants, food processing, pulp & papermaking, steel and other metal processing, mining, and in power generation including coal, nuclear and electrical generating stations.

Advantages

Open channel
Non-clogging
Quiet running
Insensitivity to abrasion
Gentle pumping
Modular system
Long tool life

Design Guidelines: Wastewater Pumping and Piping Systems

• Keep suction piping as short as possible, approximately 10 to 15 feet.
• Pipe line velocity: 6 to 8 fps (feet per second)
• Provide cleanouts and flushing connections
• Avoid the use of check valves
• Full port pinch valves for isolation
• Hardened metal fully recessed “vortex” impeller pumps
• Pumps having flushed mechanical seals or flush-less hydrodynamic seals
