Sulzer ABS Piranha grinder pump series
The Piranha range is split into the S series, which includes the S21, and the PE series with IE3 motors. In front of the impeller sit a spiral bottom plate, a stationary cutter ring and a shredding rotor that cut cloths and plastic before they reach the hydraulics. The bottom plate is adjustable to take up wear. Versions exist for 50 Hz and 60 Hz, three-phase 400 V and single-phase 230 V supplies.

Ordering Sulzer pumps and spare parts: what we need
Send the full type designation and the serial number from the nameplate, the supply voltage, phase and frequency, the discharge size, and whether an explosion-protected version is required. For cutter or seal parts, the nameplate photo is enough for us to trace the parts list. This applies equally to GCC municipal projects.

FAQ
Questions about Sulzer
Common questions about Sulzer equipment, part numbers and supply to Oman and the GCC.
01What is the difference between Piranha S and Piranha PE pumps?
Both are submersible grinder pumps with the same cutting principle. The PE models are fitted with premium efficiency IE3 motors, while the S series is the high-head line and has a reversible cutter that can be turned and used on its second side before it needs replacing. The model on the nameplate tells you which family you have.
02How does the Piranha cutting system work?
A shredding rotor turns against a stationary cutter ring directly ahead of the impeller, with a spiral bottom plate guiding solids into the cutter. Cloths, plastic bags and similar items are cut small enough to pass through small-diameter discharge lines. The bottom plate can be adjusted to restore the clearance to the impeller as parts wear.
03Where are Sulzer Piranha grinder pumps used?
Sulzer describes them for sewage removal from houses and remote settlements where a conventional gravity sewer is too costly, where the ground rises and falls, or where only small-diameter pressure pipe can be laid. They are also used for commercial wastewater and sites such as motorway service areas.
04When was Sulzer founded?
Sulzer was founded in 1834 in Winterthur, Switzerland, as Gebrüder Sulzer, and is still headquartered there. Sulzer AG is listed on the SIX Swiss Exchange.
05Is Seven Star LLC a distributor of Sulzer?
No. Seven Star LLC is an independent industrial supplier based in Muscat. We source Sulzer pumps and parts through commercial channels, check the model or order code against the manufacturer's documentation, and provide the manufacturer's datasheet and the certificates the manufacturer issues with the order, on request.
