Gianneschi

Since 1969 Gianneschi Pumps and Blowers (previously known as G&R up until 2004) have been popular all over the world serving the marine industry from pleasure boats to commercial vessels and military ships between 12-120mts in length.

Due to continuous growth & success, it was necessary to renovate and en-large the factory space. The factory was shifted to a covered area of 4000m² fully equipped with automatic tools such as a painting machine and a vertical storage. Completely made in Italy the pumps, water pressure systems, blowers, water heaters, engine pumps, compressors and dc/ac motors achieves the highest quality on the market;  thanks to the fact that every product is tested before being delivered to the customer. Gianneschi is able to please their clients in every way - assisting them with their requests whether administrative or technical. Gianneschi explores different ways to simplify customer’s life on board by offering the best type of package which would suitable for the application. It could be one product or one of the complete kits which saves time and money for the customer.

When a product is purchased from Gianneschi, sales and service points worldwide are available to the customer’s wherever they may be. In 2004 Gianneschi also introduced Gianneschi Service which is able to repair and give assistance on products.



  • The electric pumps “MVG” series are volumetric pumps. A metal single-thread helical rotor formed by an endless screw turns in a floating rubber stator with double-thread helical profile. The pump can practically manage all types of fluid like dirty, viscous and/or with suspended parts. Even if they are self-priming pumps, in order to allow the self-priming and lubricate the stator it is necessary to fill the body pump with water. Gianneschisuggests to install a non-return valve on the suction pipe in order to prevent the pump emptying. At the first start or after a long time of no use, it is important to verify the correct direction of rotation in order to avoid the unscrewing of the rotor. ApplicationsEmptying of waste, liquid with small suspended parts etc. Construction features Body pump: BronzeScrew rotor: Stainless steel AISI 316Stator: Bunan NBRMechanical seal: Graf-allox-NBRUniversal joint: Stainless steel AISI 316Motor shaft: Stainless steel AISI 316 Motors Insulation: “F” classProtections: “IP 22”for dc ; “IP 54/55” for acVoltages: 12 - 24 V dc, 1Ph 230V ; 3Ph 230/400V ac 50/60 Hz
