Products / FZ-SP Self-priming pump
FZ-SP · Food-grade stainless steel
Self-priming pump
Reliable suction, even from below.
Our FZ-SP self-priming pump is built in stainless steel for the food industry and for milk transfer. Thanks to its self-priming capability, it draws liquids even from below its own level and automatically resumes operation after an interruption — with no manual intervention.
Hygienic, robust and reliable, it is ideal for foaming liquids and for transferring product between tanks and containers. Its modular design simplifies maintenance and keeps running costs low.
Made in Italy, it combines proven engineering with high energy efficiency to support demanding food, beverage and dairy processes.

The nameplate can be yours
Every FZ-SP leaves the workshop with a stainless steel nameplate: model, serial number, power, speed, flow and pressure — readable for the whole life of the pump.
- Your logo and your addressOn request we engrave the nameplate with your own logo and address: the pump reaches the plant under your name.
- The curve of the pump you orderAsk us for the performance curve of your exact configuration: we send it with the quotation.
Performance curves
Interactive tool — flow up to 24 m³/h, head up to 26 m: browse the real H–Q curves and find the right model for your duty point.
Performance by model
Values at 50 Hz and 1450 rpm, read from the H–Q curves above: maximum flow and maximum head, that is at zero flow.
