Motor Driven Gear Pumps

These new electric gear pump units have been designed as the result of over thirty years experience in the field of developing and manufacturing gear pumps. The application possibilities are numerous; the pumps are self-lubricating and are able to operate with oils or any other fluid with proven lubricating capacity. These pumps can therefore be utilized in the fields of lubrication, refrigeration, hydraulics and, more generally, for the circulation of fluids for machines, motors and linear motion applications; these units can also be employed on recirculating systems without the need for particularly fine filtering of the circulation fluid.

One of the most striking features of these pumps is the high degree of silentness in operation, obtained with the use of gears specially designed for this type of unit. Also, thanks to particularly precise machining and finishing, a significant improvement has been achieved in efficiencies compared to all previous similar models produced. To ensure an external seal the pumps have an "O" ring located between the pump body and the relative cover in addition to a lip seal on the main shaft.

The body of the pump is produced in hydraulic cast iron and the gears and relative shafts in chrome-nickel steel - carburized, hardened and ground. The body of the low flow rate pump (up to 500 cc/min) is made of sintered steel; the shafts and gears in carburized and hardened steel with a seal on the main shaft.
