Symbols and notices used in this booklet: Presence of dangerous voltage. Non-compliance may result in personal injury. Danger of an explosion occurring. ATTENTION! Non-observance may result in damage to the unit or negatively affect its performance. NOTE: Important information for particular attention. Application areas Piranha submersible grinder pumps have been designed for the pumping of sewage containing faecal matter from buildings and sites where the location is below the sewer level.
The general and specific health and safety requirements are described in detail in the “Safety Instructions for Sulzer Products Type ABS” booklet. If anything is not clear or you have any questions as to safety make certain to contact the manufacturer Sulzer.
Detailed technical information is available in the technical data sheet “Submersible Grinder Pump Type ABS Piranha 09 - 125” which can be downloaded from www.sulzer.com > Products > Pumps > Submersible Pumps. Maximum noise level ≤ 70dB. This may be exceeded in certain circumstances.
General design features Submersible grinder pump fitted with a shredding system hydraulic. The shredding system is located before the impeller and consists of a shredding rotor in combination with a stationary cutting ring fixed to a spiral bottom plate. Design features Piranha-S Shredding system Cast iron lifting handle and Bottom plate adjustment...

Pressure release screw Upper bearing - single row Motor chamber drain plug/ pressure test point Motor housing Motor with thermal sensors Volute 10-pole terminal block Stainless steel shaft Impeller Moisture sensor (DI)
Weight per foot (lbs) 0.29 0.42 0.74 1.18 1.98 Weights of accessories, other than or in addition to those listed, must also be included when specifying the working load of any lifting equipment. Please consult with your local Sulzer representative prior to installation.
The lifting equipment, e.g. crane and chains, must have adequate lifting capacity. The hoist must be adequately dimensioned for the total weight of the Sulzer units (including lifting chains or steel ropes, and all accessories which may be attached). The end user assumes sole responsibility that lifting equipment is certified, in good condition, and inspected regularly by a competent person at intervals in accordance with local regulations.
Mounting and installation The regulations covering the use of pumps in sewage applications together with all regulations involving the use of explosion-proof motors should be observed.The cable ducting to the control panel should be sealed off in a gas-tight manner by the use of a foaming material after the cable and control circuits have been pulled through.
Electrical connection Before commissioning an expert should check that one of the necessary electrical protective devices is available. Earthing, neutral, earth leakage circuit breakers, etc. must comply with the regulations of the local electricity supply authority and a qualified person should check that these are in perfect order.
Operation with frequency inverters (Piranha-PE three phase): The stator design and the insulation grade of the motors from Sulzer means that they are suitable for usage with frequency inverters. It is however essential that the following conditions are met: • The guidelines for EMC (electromagnetic compatibility) are complied with.

10.5 Changing direction of rotation The direction of rotation should only be altered by a qualified person. If the direction of rotation is incorrect then this is altered by changing over two phases of the power supply cable in the control panel. The direction of rotation should then be rechecked NOTE: The direction of rotation measuring device monitors the direction of rotation of the mains supply or that of an emergency generator.
When carrying out repairs, only original spare parts supplied by the manufacturer should be used. Sulzer warranty conditions are only valid provided that any repair work has been carried out in an Sulzer appro- ved workshop and where original Sulzer spare parts have been used.
Shaft sealing is by means of double mechanical seals (Piranha-PE), and mechanical seal / lip seal (Piranha-S). ATTENTION! Once removed, bearings and seals must not be re-used, and must be replaced in an approved workshop with genuine Sulzer spare parts. 12.6 Maintenance of lifting stations.
Troubleshooting guide Fault Cause Pump does not Moisture sensor shutdown. Check for loose or damaged oil plug, or locate and replace faulty mechanical seal / damaged o-rings. Change oil. Air lock in volute Shake or raise and lower the pump repeatedly until resulting air bubbles no longer appear at surface level.
