AP series positive displacement-almost-vacuum pumps
The AP series process pumps are part of the tailor made production of Belli Meccanica.
The body of these pumps is equipped with a particular structure with guide that allows to work up to 12bar of pressure in continuous service 24/7 and with impressive dry suction rate. The pump body is designed and customized according to the flow rate and operating pressure required, in order to produce a pump with specific sizing and perfectly calibrated on the application. The materials are selected according to the characteristics of the liquid to be pumped and go from cast iron and carbon steel to stainless steel or bronze. This type of pump is also manufactured according to Atex zone 1 standards, with single or double body and with flow rates up to 500mc / h and is used in all those processes where very high reliability is required in continuous service. For example fuel supply of burners or injection of additives or methyl esters in large pressure pipes are typical applications of these pumps.
The AP series pumps have an impressive dry suction lift capability: more than -0.9 bar of vacuum (more than 9 meters of water column). The internal special geometries and perfect clearances makes the pump capable of working also with mix of liquid and gas bubbles, pushing with a behaviour similar to a compressor.
The npsh required by the pump is very low up to 0,5m of npshr.
These particular features makes the pump a sort of hybrid self priming-vacuum-compressor pump that can work fine also with vessels and reactors in vacuum and in applications where the liquid is very close to the boiling point.
Atex skids for solvent transfer and dosing
Belli Meccanica designs and creates custom skid for dosing and transfer of solvents and flammable liquids
The skid in picture was designed for an important italian company that operates in the solvent market
The customer required a pump on skid capable of going in suction from undergronud tanks and pushing the liquid to another storage tank. The pumped quantity had to be dosed very sharply with the aim of creating a solvent blend in the discharge tank. The request was also for a portable solution so that the pumps could be used in different tanks and pumping points in the outside area.
Because of the high vapour pressure of the pumped liquids, the pump should be capable of high suction and low npsh required. Furthermore Atex zone 1 compliance was requested
Pompe a disco cavo in acciaio inox serie L-HY
La nuova serie di pompe a disco cavo in acciaio inox serie L-HY rappresenta una novità assoluta nel campo delle pompe a disco cavo oscillante.
La pompa è stata sviluppata per offrire la massima qualità ed affidabilità in tutte quelle applicazioni che richiedono alti standard qualitativi e materiali inossidabili o speciali.
La base della pompa in acciaio inox è realizzata partendo dal pieno tramite lavorazione cnc, in modo da offrire una elevata finitura delle parti a contatto col liquido pompato e rugosità fino a Ra 0.8, altrimenti non ottenibile con le basi in fusione standard.
