Submersible grinder pump type ABS Piranha

Main benefits

Effective and economical dewatering using small-diameter discharge lines
Unique cutting systems provide blockage-free operation
Adjustable bottom plate maintains continuous efficiency
High efficiency IE3 motor on Piranha PE gives energy savings
Flexible installation options: fixed with pedestal / guide rail and transportable

Main applications

Sewage removal from living units and houses in remote settlements where:

The laying of a conventional sewer would be too expensive
Large ground undulations are present
It is only possible to lay small-diameter pipe lines

Piranha – the submersible grinder with the unique cutting system

Unique cutting system for Piranha PE and S

This cutter system has a unique concept in grinder pump design. It consists of a spiral bottom plate and a stationary cutter ring combined with a shredding rotor located in front of the impeller, for optimum blockage-free running. The shredding system can shred challenging items such as cloths and plastic bags.

For a longer service life, the high head version of Piranha S has a reversible cutter that can be rotated. The cutter face can be used on each sides before the cutter needs replacing.

Adjustable bottom plate on Piranha PE and S

To counteract the effects of wear and to maintain efficiency, the optimum clearance between the bottom plate and the impeller can easily be restored.

Flexible installation options

The Piranha grinder pumps can be installed in several configurations to fulfill virtually any requirements, including:

Fixed installation with pedestal (guide rail assembly)
Free-standing transportable applications
Installation in areas where large fluctuations in terrain elevation are present

Sulzer pumps and engineering expertise halve costs for a wastewater system in Norway
Norway is famed for the beauty of its rugged landscapes, but hilly or mountainous country can be a nightmare for wastewater engineers. With no flat or downhill route available between communities and the wastewater treatment facilities that serve them, reliable infrastructure requires some creative thinking.
Pressurized dewatering: the economical solution for wastewater disposal problems
Pressurized dewatering is typically suitable for sewer systems in outlying areas with no direct access to local gravity sewer lines. It solves ground water pollution problems by utilizing current pumping technology combined with modern trends in sewage removal.
Sulzer solves motorway jams
Drivers rely on motorway rest areas and service facilities to ensure their comfort and safety on long journeys. However, for Austrian operator ASFiNAG, heavy use of these facilities was leading to maintenance headaches. Now, thanks to Sulzer’s Muffin Monster™ grinder and Piranha pump technology, wastewater pump blockages are becoming a thing of the past.

Applications

Commercial waste disposal from toilets
Commercial wastewater from toilets comprises all sewage water flushed from toilets on commercial, industrial or public properties.
Commercial wastewater without toilet waste
Commercial wastewater without toilet waste includes drainage and grey wastewater.
Domestic waste disposal from toilets
Domestic wastewater from toilets comprises all sewage water flushed from toilets or residential properties.
Domestic wastewater without toilet waste
Domestic wastewater without toilet waste includes drainage and gray wastewater.
Pressurized systems
Pressurized sewage systems are well suited to outlying locations such as holiday areas and coastal regions, where there may be no direct access to local gravity-based systems. They can also provide an economical alternative to gravity sewers, since they involve smaller pipeline diameters and less excavation.
