Rotary Gear Pumps

APPLICATIONS

Transfer of various grades of oils like light Diesel Oils, Fuel Oils,Transformer oils, lube oils, castor oils, Grease , wax etc.

Transfer of chemicals like sodium silicate, caustic soda, resins,enamels, adhesives, fatty acids, paints and varnish, pulp, juices,

Syrups, Alcohol, Kerosene, etc. Atomising of fuel oil at high pressure for burners and boilers. Lubrication of gear boxes, cranes, Machine tools, etc. Cooling and filtering in machine tools. Heat transfer liquids for chemical vessels. Hydraulic systems for presses, power pack units etc.

These pumps are simple in design and robust and sturdy in construction. Only testedmaterials are used to give them long life. They are built in various sizes and versions tosuit every possible industrial application.

These pumps available either foot mounted or flange mounted.Pressure range - 0 Kg./cmto 10 Kg./cm

Capacity - upto 4000 LPMSize - 3/8" to 8" Inlet - outlet

SPECIAL

FEATURES

Direction of rotation can be given as per client's requirements. Suction and delivery have threaded connections upto 20" BSP.

Flange connections can be given on request. 3" & above pumps haveintegral flange connection.

As per clients requirement pump is provided with electric motor, gearbox, diesel engine, base plate, coupling, guard, flanges, pulley & BeltDrive, Trolley Mounted, etc.

Pump are also available in steam jacketed design specially suitablefor liquids which solidify or become highly viscous at roomtemperature like LSHS, Wax, Coal Tar, Adhesives, etc.

Pumps are fitted with Mech. Seal, Gland Packing or oil seal as perclient's requirements.

Pumps are available under Low pressure range (0 to 10 Kg/cm) aswell as High pressure range (11 to 40 Kg/cm) On the basis ofrequirements.

Pumps are available in SS 304, SS 316, A 216 Gr. WCB, mild steel,gun metal, Aluminium Material also.

Pumps can be offered with external bearing design suitable forliquids which do not have lubricating property like molasses, high

temp. oil, Corrosive abrasive liquid, Pharmaceutical Products, etc.

Pumps are designed, mfd. & tested as per API Std. 676. A builtin relief wall is provided in Pump Back Cover. It can be

adjusted externally to ensure that the pump does not build uppressure above certain preset limit. This prevents overloading of the

motor as well as probable damage to the pump.
