All Dimensions are in millimeters. Unless otherwise stated specifications are subject to charge without prior notice as improvements are made from time to time.

These pumps give max. pressure of 35 kg/cm2 yet for continuous duty max. recommended pressure is 30 kg/cm2 pump can also be used at 2800 R.P.M the capacity will have approx. Double of normal duty condition. Pump rotation of direction can be clockwise & anti-clockwise as per requirements.

We wish to associate ourselves with you to serve you better, faster and at reasonable prices .We request your kind co-operation in our endeavour and assure you of our best attention is given a chance.

Every DurgaFIG pumpis tested 100% for its performance at 1440 rpm with oil of viscocity 35 cst at normal working temp. and pressure and pressure of 30 kg/cm2.

Rotary Gear Pump

Rotary Gear Pump Characteristics

Capacity:

All Positive displacement rotary gear pumps are self priming pumps in which the efficiency of transferring the liquid is deter mined by the cavity between the gear teeth.The accuracy in capacity thus depends upon the accuracy of teeth cutting and its profile. The DR series of Durgagear pumpshas modified profile teeth cutting yield accurate capacity within the force range. The double helical heringesbone gear design delivers constant volume without any pulsation. It also avoids internal slipage and gives great volumetric efficiency.

Pressure:

All Durgagear pumpsare self priming type pump with suction lift of 5 metres at mean viscocity and speed of 1440 RPM. The liquid flows into the pump due to a difference in pressure is called NPSH (Net Positive Suction Head), the accurate calculation of which is very much necessary for the selection of a pump. When the suction lift is more than 5 meters the pump has to be run at slow speed.
The discharge pressure indicated by the pump is nothing but the over coming of pressure exerted by the resistance of the pipeline and the shearing force of the Liquid.Thus a gear pump does not develope pressure by its own but work against the system pressure exerted on it.

Rotary Mini Pumps

Rotary Mini pump have wide application in lubrication of Machine Tool, Press Tool, Chemical, Pharmaceutical, Textiles, Printing, Canning & Bottling, Plastic Processing, Moulding Machines. Other application relate to transfer of fluid, burning oil, hydraulic power packs, rotary filters as well as vehicle engine lubrication.

Rotary Mini pumps are available in different sizes depending upon the discharge value in LPM at 1500 shaft RPM.

These pumps are generally non-reversible i.e. by change of direction of rotation of pump shaft, suction and delivery ports get inter changed.

Rotary Mini Pumps normally don't have built in relief valve. However if demanded, built in relief valve can supplied.

Salient Features

	Compact and good finish assembly of pump and motor makes it a noiseless proposition.
	These pumps can be made reversible if required (at RPM more than 400).
	For zero leakage facility, a mechanical seal can be provided.
	Available with various accessories like suction strainer, relief valve, inline filter.
	Provision for custom built pumps.
	Chemical handling & water discharge pumps are also available in same range.
	Max pressure is 25 bar for all types of mini-rotary pumps for oil of 68 cSt viscosity.
	Discharge of fluid is in between 0.5 LPM to 40 LPM (at 1500 RPM).
	Maximum recommended temperature of fluid is 80C.
	Standard pumps are ment for oil, however these pumps can also be designed for corrosive fluid.
	Recommended Viscosity range of fluid 10 -1000 cSt.
