Gear pump G 11-21 101

Gear hydraulic pumps Г 11-21 are used in lubrication and hydraulic systems of metalworking equipment, hoists, presses and other machines. The Г 11-21 pump is intended for pumping of technical oils and other liquids providing strengthening of capacity, without mechanical impurity and do not create corrosion of working bodies of the pump. The kinematic density of the fluid is from 17 to 400 mm 2 / s (cCt), the temperature of the fluid is from + 10 ° C to + 55 ° C. The lower limit of viscosity limits the lubricating ability of fluids, the upper - engine power and suction. Pump Г 11-21 in nominal mode provides a pressure at upbringing of 2.5 MPa (25 kgf / cm2). The special design of the groove in the surveillance chamber increases the filling of the interdental cavities, reduces the resistance in the surveillance chamber and, as a result, increases the efficiency and feed rate of the pumps. Execution of injection chambers in the form of a narrow slit reduces the load on the supports and increases the solution. The pump Г 11-21 fastens to a plate through apertures on paws, and to the engine through the coupling.
