1. INTRODUCTION

This user's and maintenance manual refers to motor-driven gear pumps 37000-3400000, 3410-

It is recommended that this manual is carefully kept in good condition and is always available to persons requiring to consult it.

To request further copies, updates or clarifications with respect to this manual contact the Engineering Department at Dropsa

SpA.

The use of the pump referred to in this manual must be entrusted to qualified personnel with a knowledge of hydraulics and

electrical systems.

The manufacturer reserves the right to update the product and/or the user's manual without the obligation to revise previous

versions. It is however, possible to contact the Engineering Department for the latest revision in use. You can find additional

copies and newer revisions of this document from our website http://www.dropsa.com. Alternatively contact one of our sales

offices.

The pump, and any accessories mounted on it, should be carefully checked immediately on receipt and in the event of any

discrepancy or complaint the Dropsa SpA Sales Department should be contacted without delay.

DROPSA S.p.A. declines to accept any responsibility for injuries to persons or damage to property in the event of the non-

observance of the information presented in this manual.

Any modification to component parts of the system or the different destination of use of this system or its parts without prior

written authorisation from DROPSA S.p.A. will absolve the latter from any responsibility for injury or damage to persons and/or

property and will release them from all obligations arising from the guarantee.

Instructions for the correct ordering of the required model, and a list of importers, is shown in Section 4.

These new 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 utilised 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.

WARNING

For all the motor-driven pumps we have shown the applied power to the motors in function of the maximum pressure demand

indicated in the table. For higher pressures the motor must be suitably sized; accordingly, to obtain a quotation, state the

voltage, the maximum operating pressure and if the service will be continuous or intermittent. (Max pressure = 30 bar for

continuous service); (max. pressure = 60 bar for intermittent service); (For cylinder block versions from 1-30 bar it depends form

delivery and kW). Working temperature of the fluid –20 - +100 degrees with low to medium velocity oil.

On request flameproof motors can be supplied in various voltages.
