Sulzer ABS Piranha Grinder Pump

Piranha Grinder Pumps provide effective and economical dewatering using small-diameter discharge lines in private, municipal and industrial areas. These Sulzer submersible pumps contain the most effective cutting system for use in pressure sewer systems.

Features of the ABS Piranha Grinder Pump include:

  • Piranha cutting system - spiral-grooved bottom plate and stationary cutting element
  • seal leak detection system
  • premium efficiency motor (IE3) in accordance to IEC 60034-30
  • double mechanical seals
  • small diameter discharge
  • temperature monitoring
  • lubricated-for-life, heavy duty ball bearings
  • adjustable bottom plate
  • explosion proof - ATEX, FM and CSA standards available 



The DrainAce Compact is commonly found in restaurants, basements of high-rise buildings, boardrooms, laboratories, doctor or dental surgeries, construction sites and portable buildings. Units are also available for greasy waste discharge from grease arrestors. 


Piranha submersible pumps have been designed for effective and economic dewatering using discharge lines of small diameter, in private, municipal and industrial areas.

These grinder pumps are suitable for the following applications:

  • sewage removal from living units and houses in remote settlements, where the laying of a conventional sewer would be too expensive, where large ground undulations are present or where it is only possible to lay pipelines of small diameter.
  • sewage removal from motorway resting sites, communal buildings and for renovation of buildings or areas of a city
  • for use in slaughter houses, food processing plants, paper factories, agriculture and similar areas
  • Piranha 08 and 09 are specially designed for private and domestic applications
  • maximum allowable temperature of the medium is 40oC, or short term to 60oC (max 5 mins)




The Sulzer ABS Piranha Grinder Pump provides a means of effective and economical wastewater transport utilizing small-diameter discharge pipes as opposed to larger diameter pipes required for gravity systems.

There are two varieties of the ABS Piranha Grinder Pumps: Piranha PE and S Series.

Piranha PE Grinder Pump

Sulzer’s premium range of submersible grinder pumps, type ABS Prianha PE, are equipped with Premium Efficiency IE3 motors in accordance to IEC 60034-20. These motors provide the perfect balance of reliability and energy consumption. The PE Grinder Pump offers operators the zero blockages and low life cycle costs, providing reliability and energy savings.

Piranha S Series Grinder Pump

The standard range of submersible grinder pumps, type ABS Piranha S, are equipped with water-tight, fully encapsulated, flood-proof motors. The pump and motor section form a compact unit, providing an economical, yet robust solution without compromising on the reliable design.

Effective cutting system

The Piranha cutting system consists of a lobed rotor cutting element attached to a centrifugal impeller working in tandem with a stationary cutting element fastened to a spiral-grooved bottom plate. The lobed rotor turns inside the stationary cutter designed with wave-shaped castellations. The number of waves is one less than the number of lobes on the rotor. The normal pumping action of the impeller causes water and solids to flow into the cutting elements and as the solids are sheared into small particles, they are pumped by the impeller into the discharge pipe.

Installation to fit any need

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

Fixed installations with pedestal (guide rail assembly)

Freestanding, transportable applications

Installation in areas where large fluctuations in terrain elevation are present.
