gear pump , Iran
A hydraulic gear pump consists of two meshing gears inside a housing. This pump is a fixed-displacement positive displacement type. Its flow rate ranges from 0.1 to 150 gallons per minute. Its working pressure can reach 250 bar. Its volumetric efficiency is typically between 85% and 95%. Its standard rotational speed is from 900 to 3600 RPM. These pumps are built in external and internal gear types. Their design is simple and robust. Common housing materials include aluminum, cast iron, and steel. They are suitable for mineral oils with a viscosity of 10 to 160 cSt.
Minimal clearance between gears and housing is key for performance. This clearance is usually maintained between 10 and 20 microns. Gear pumps generate relatively high noise levels. Their sound pressure level is often between 70 and 85 dB. They have low sensitivity to fluid contamination. These pumps typically lack internal pressure regulation. They require an external relief valve. They provide constant torque at various speeds. Their initial and maintenance costs are very economical. These pumps are widely used in industrial and mobile hydraulic systems.You can order and buy gear pump from Iran by contacting us through whatsaap and email.

Key Advantages and Disadvantages of Hydraulic Gear Pumps
Hydraulic gear pumps, a type of positive displacement pump, are known for their compact and simple design. They are self-priming and provide a fixed displacement output proportional to rotational speed. They are typically suited for medium working pressures commonly up to around 250 bar and common flow rates up to 1000 liters per minute. Their volumetric efficiency often ranges between 70% and 90%, and they can effectively pump high-viscosity fluids even over 1,000,000 cP. Their primary disadvantage is sensitivity to abrasive particles and solids in the fluid, which causes wear and gradual efficiency loss. Also, compared to piston pumps, they lack the capability for very high-pressure operation, and their output flow has some pulsation which may require a damper. Their operation is usually accompanied by noticeable noise from gear meshing.
